Javac CDC30 Cordless Power
Cut the Cord on Traditional HVAC Jobs: Explore Modern Opportunities
You know the scene. You reach a Sydney rooftop and the power point is thirty metres away. You try to wrangle an extension lead across hot sheet metal while the wind kicks up. The cord snags on a ladder rung. The tenant watches. You just want to pull a clean vacuum and move on. That is the daily grind for many Australian techs in summer.
The answer is simple. Remove the cord. The javac cdc30 cordless vacuum pump gives you true portable power. You set the pump down, fit your large-bore hoses, and press go. No generator. No long lead. No shared power boards on a busy site. Your vacuum log starts on time and your day runs sharper.
This cordless shift is not a gimmick. It is a change in workflow. You move faster on high-rise jobs in the CBD. You work safer on pitched roofs in Brisbane storms. You cut set-up time on rural installs where mains power is not available. You can finish a split system upgrade in Melbourne without asking the shop owner to shut off a coffee machine so your pump does not trip a breaker.
Javac built the CDC30 in Australia to solve Australian problems. The pump is compact. The handle is solid. The case takes a few knocks in the ute without drama. The motor is tuned for heat and dust. The result is a tool that matches our climate and our work pace. That is why cordless is winning jobs across the country.
Why the Javac CDC30 Stands Out in HVAC Tools
The CDC30 is a two-stage vacuum pump that moves 30 litres per minute. Those figures live in the real world. You can see the pull-down speed on your micron gauge and you can feel the pump settle into a steady hum. The design target was simple. Pull deep vacuum fast enough for residential splits and many light commercial jobs while keeping weight and size low.
Battery freedom is the heart of the CDC30. The platform accepts popular trade batteries. You can run Milwaukee M18 packs or Makita 18V packs with the right adapter. That means you do not need a brand-new charging system on the van. You use the batteries you already own for your drill, driver, and impact wrench. One battery family keeps your day simple and your load light.
Ultimate vacuum matters for warranty and for moisture control. The CDC30 is rated to an ultimate vacuum of 15 microns under lab conditions. Out on a hot driveway in Perth you will not stare at a lab sheet. You will trust your micron gauge and your dry nitrogen sweep. The pump has the headroom to get you there when the system is tight and your lines are clean.
The unit is ready for modern gases. The CDC30 is designed for use with A2L refrigerants and is R32 compliant when you follow safe work steps. The motor and sealing choices reflect that. The valves are placed with care. The instructions focus on purge, fresh air, and spark risk. The pump is a tool, not a shortcut. Use it right and it supports safe work every day.
Build quality is where Javac shines. The CDC30 is designed and built in Australia by a team that has delivered pumps since the sixties. You feel it in the castings, the fasteners, and the way the carry handle sits in the hand. You can service the unit locally. You can speak to a local tech if you need a part. That is worth real money over the life of a pump.

Why Australian Tradies Prefer the Javac CDC30 for HVAC Jobs
Every minute on a ladder is a minute of risk. Corded pumps force you to plan power access and cable runs before you even start. The javac cordless workflow removes that barrier. You place the CDC30 near the system, use short, fat hoses, and keep your steps to a minimum. Your hands stay free and you avoid trips and tangles. That is safety by design.
The next win is reach. Mobile jobs are easier when you do not need a generator. Brisbane roof jobs often have power, but not always where you need it. Rural installs in central NSW can be an hour from a store. A reliable battery vacuum pump means you are ready to work the moment you open the van door. You save time on every call.
Shared batteries are not just handy. They cut costs. Most teams already carry three or four 5Ah or 8Ah packs for day-to-day work. Those packs can power the CDC30 with an adapter. You are not dragging a new charger system into the shed. You charge all packs at night on the same board and you know which ones are healthy.
Weight and size matter at the end of a long day. The CDC30 hits the sweet spot. It is heavy enough to feel stable on the roof. It is light enough to carry in one hand while you hold a hose set in the other. The footprint fits a standard van shelf. The rubber feet settle well on tile and on concrete. You can set the pump close to the service ports and keep hose runs tidy.
The last reason is heat. Australia bakes pumps every summer. Javac designs for hot motor housings and long run cycles. Air paths and clearances are set up for hot outside days. The case resists the bumps and scuffs that come with scaffolds and stairs. You can feel the pump was made for our conditions rather than adapted from a colder climate.
Real-World Australian Applications of the CDC30
Picture a Sydney CBD high-rise with street noise below and a narrow plant-room walkway above. You need to evacuate a split system without laying a cord across a corridor used by cleaners and security. The CDC30 shines here. You carry the pump and hoses in one trip, set up, and start the pull. You check micron readings on your gauge and add the result to your service notes. The work area stays clear and safe.
The next day you are on a Brisbane retail rooftop. Afternoon storms are forecast. You want to get off the roof before the first gusts. The cordless set-up is quick. You remove cores, place the pump, and start drawing down. You keep the case on the leeward side of the unit to avoid spray. When the rain comes you are already closing valves and packing the hose set. The job finishes early.
Perth brings a different story. A remote mining site has a small generator running lights and a fridge. Power load is tight. A corded pump would force you to turn something off or run a second genny. The CDC30 lets you work without touching the shared power board. Your battery plan covers the shift and your log shows a clean vacuum history for the maintenance record.
Back in Melbourne you complete a set of split system upgrades across townhouses. Parking is cramped and access is tight. The cordless pump makes each install a single run from the van. No cable reel. No hunt for a safe outlet. The workflow is smooth and the client sees tidy gear and a careful tech. That impression builds trust and repeat work.
Regional jobs round out the picture. Rural properties often have old boards and limited sockets near the outdoor unit. A battery pump is the fastest path to a good result. You stage the job, purge with nitrogen, and pull down. Your micron gauge tells the truth and your pump keeps pace without drama. The day finishes on time even when power is patchy.
Did you know? Cordless can improve evacuation speed
Shorter hose runs are easier when the pump sits right beside the service ports. Less hose means less internal volume. That can reduce pull-down time compared to a corded pump placed near a distant power point. Good hose choice and core removal still matter, mate.
CDC30 vs Corded Pumps: Performance Comparison
Numbers help you plan your kit. Cordless is about more than freedom. It has to hit targets that keep systems dry and clean. The table below compares common field choices. Figures are indicative and may vary with outside heat, hoses, and service practice. Always trust your micron gauge and follow best-practice methods for evacuation.
| Model | Flow (L/min) | Stages | Ultimate Vacuum | Power Source | R32/A2L Ready | Best Use Case |
|---|---|---|---|---|---|---|
| Javac CDC30 Cordless | 30 | Two-stage | Down to 15 microns (lab) | 18V battery | Yes | Mobile work, rooftops, rural |
| Javac Vector 90L corded pump for heavy-duty applications | 90 | Two-stage | Down to 1 micron (lab) | 240V mains | Yes | Large systems, long runs, commercial |
| Javac CAL 81 R32-rated pump for flammable refrigerants | 75 | Two-stage | Deep vacuum capable | 240V mains | Yes | R32 service, fast pull-downs |
Use this table as a quick guide when you decide what to carry in the van. For everyday split installs and mobile service, the CDC30 is a strong choice. For big commercial work with long line sets, a high-flow corded pump like the Vector may still be the best option. You can carry both and choose per job.
Maximising Battery Life: Tips for Longer Runtime
A cordless pump is only as good as your battery plan. In Sydney you might do three split installs in one day with travel between sites. Each pull-down and rise test takes time. Plan enough amp hours to cover the whole run. Many teams start the morning with four fully charged 5Ah or two 8Ah packs and keep a charger on the passenger seat for top-ups at lunch.
Milwaukee M18 packs are common on Aussie utes. Makita 18V is also strong in HVAC. The CDC30 works with adapter options so you can match your existing platform. The key is not brand. The key is confidence that your packs are healthy. Mark each battery. Rotate them. Retire weak cells early. Your pump deserves the same care you give your drills.
Runtime depends on outside heat, hose length, and system size. A solid 5Ah pack can often cover a domestic pull-down and a stable rise test when the lines are dry and you remove cores. Tough systems may need a second pack. Track your own numbers. Write runtimes in the van logbook. After two weeks you will know how many packs you need for your route.
Charging stations need love too. Keep your chargers out of direct sun. Vent the van. Secure the charger to avoid cord stress. If you drive long distances, consider a clean inverter set-up from a licensed auto-sparky. Your charger will run cooler and your packs will last longer. Little habits protect your investment.
Cold mornings change battery behaviour. A Canberra dawn can drop pack output. Warm a spare pack in a jacket pocket while you use the first one. Swap at the right time and your vacuum stays steady. Do not leave packs on hot dashes or near heaters. Temperature care keeps runtime predictable across seasons.
How to plan your battery rotation
Label packs one to four. Start job one with pack one. Use pack two on the next job, and so on. Charge one and two at lunch if needed. Record runtime in minutes beside each pack number. Replace the first pack that drops performance before it strands you on a roof.
Investment Guide: Smart Tools and Equipment for Australian Contractors
Value is more than a price tag. The CDC30 earns its place by reducing set-up time and removing generator hauling. The dollars make sense when you count labour saved on ladders, the fuel saved by leaving the genny at home, and the return trip you did not need because a shop power board tripped mid pull-down. That is real margin saved, job after job.
You can buy the unit as pump-only if you already run a compatible battery platform. If you want a full kit, consider adapters, cases, and hose bundles that suit your work. Choose what matches the jobs you do most often and the packs you already own.
Many contractors carry a corded backup for large systems. A common pairing is a portable cordless pump for everyday installs with a heavier unit ready for big lines. If that suits your plan, the Vector 90L is a strong partner when speed and deep vacuum margins matter on bigger pipework.
R32 work is part of modern service. If you want a dedicated mains unit for flammable refrigerants, the CAL 81 is a proven choice. It complements the CDC30 when your day mixes residential installs and commercial service calls with A2L systems.
Starter kits can help a small team step up fast. When you are building out a van from scratch, the Javac PAKSPLIT kit with CAL45 cordless-ready pump is a handy reference for hoses, tools, and gauges that round out a legal, capable setup.
Finance can make sense if cash flow is tight in your first summer. Spread the cost over the peak season so the pump pays for itself in saved labour. Keep your receipts and your calibration records in one place. Clean records help at tax time and during warranty reviews.
Safety and Compliance Guidelines for Australian HVAC Professionals
Cordless does not remove safety duties. It makes them easier to meet. Place the pump in a clear spot with fresh air. Keep ignition sources away when you service R32 systems. Vent the area and follow site rules. Your risk check is still the first step when you arrive. Good habits turn into a calm, repeatable process your team can defend in audits.
Australian standards and guidance are your anchor. Check the latest info from Safe Work Australia and match your work steps to that advice. Javac designs for our conditions, but your steps protect people and property. Train apprentices on purge cycles, micron targets, and clean oil changes. Keep a spare bottle of pump oil in the van and a tray for quick swaps.
Battery safety is part of that plan. Store packs in a cool, dry place. Use branded chargers. Inspect terminals for damage. Never transport damaged packs. Keep a fire blanket and a small extinguisher in the van. These simple steps let you focus on the job, not the gear.
Essential Maintenance Tips for HVAC Tools That Keep You Moving
Clean oil is everything. Dirty oil hides moisture and masks problems in the system. Drain the pump warm after a hard pull-down. Refill with fresh vacuum pump oil from a sealed bottle. If the oil clouds during a job, change it right then. It takes minutes and it protects the motor as well as your results.
Check your fittings weekly. A tiny nick on an O-ring can ruin a good plan. Keep a small gasket kit in the van. Replace tired parts before a failure. Wipe dust from the case after roof jobs. Keep vents clear. Coil the hose with care so it does not fight you at the next stop. The best techs treat their pump like a favourite drill. That habit pays back for years.
Record your vacuum times. A notebook page or a simple phone note is enough. If a pull-down on a standard two-head split suddenly takes twice as long, you will see it in the history. That data helps you find a sneaky leak or a failing hose core tool. It also proves your method when a client asks detailed questions later.
Extend Your Wireless Workflow with the CDC30
Cordless evacuation fits well with wireless measurement. Use a digital micron gauge to watch your trend from a safe spot. Set clear targets for pull-down and for a stable rise test. Keep your graphs as a PDF with your invoice. This level of proof sets you apart and cuts call-backs. You look calm because you are calm. The numbers are in your pocket.
Round out your kit and compare other models in the same brand family when you browse our complete Javac Australian-made equipment range. For a deeper dive on this model, you can also read our CDC30 technical review. Prefer a dedicated gauge for clean logs? A popular option is the Javac BluVac LTE digital vacuum gauge, which pairs neatly with cordless evacuation and keeps reports tidy for audits.
Pro tip for clean microns
Remove cores, use large-bore hoses, and isolate the pump with a core tool for your decay test. Keep the CDC30 close to the service ports so your hoses stay short. Small wins stack up to stable, low micron numbers you can defend with confidence.
Battery Maths and Runtime Planner for Aussie Routes
Think in amp hours per job. A healthy 5Ah pack might cover one domestic pull and a rise test in mild weather, while an 8Ah pack can stretch to tougher systems. Track outside heat, line length, and whether cores were removed. Write the minutes per job in your log so you can predict the day. Two 8Ah packs can often cover three standard split installs in Sydney with lunchtime top-ups. In Darwin heat, plan extra capacity and cool packs between runs.
If a pack sags early, retire it from critical work and use it for light tasks. Do not squeeze a dying pack on a roof. The time you lose will erase any savings. Keep your inverter wiring tidy, fuse the circuit, and mount the charger where airflow is steady. A calm charging plan means predictable runtime and less stress.
Cordless Setup Workflow in Australia
Arrive and scan the site for fresh air and any spark risks, then place the CDC30 beside the outdoor unit so hoses stay short. Fit large-bore hoses and remove cores to clear restrictions. Sweep with nitrogen if the system has been open or if moisture is likely. Start the pump and watch the micron trend on your gauge from a shaded, safe spot. When you hit your target, isolate the pump at the core tool, shut off valves, and watch the decay. A stable, low rise confirms a dry, tight system. Keep the graph and notes with the invoice so your audit trail is complete.
Troubleshooting and Field Fixes
If microns stall high, check for warm, cloudy oil and swap it out while the pump is still slightly warm. Inspect O-rings and hose seats for nicks. Confirm cores are fully removed and that the gauge is away from the pump so readings reflect the system. If decay rises fast, isolate sections to find hidden moisture or leaks. In wind or light rain, shield the gauge and connections. A few calm minutes of checks usually beats a second site visit.
Warranty, Service, and Spare Parts in Australia
Keep your receipt and a copy of your calibration records with the pump. If something feels off, call support early so a small symptom does not become a big failure. The benefit of buying Australian is fast answers and local parts. A quick seal change can save a full day of downtime in January. Store the unit out of direct sun, strap it for long drives, and keep the case clean so service checks are easy.
Environmental and Site Etiquette
Work tidy and leave no trace. Keep oil changes controlled with a tray and bottle. Let in fresh air when working indoors and follow building rules. A quiet, cordless set-up lowers noise on apartments and retail sites. That goodwill matters when you are chasing repeat work across strata and commercial clients. Your process is part of your brand and a neat, safe set-up gets noticed.
Frequently Asked Questions
How long does a battery last on the CDC30?
Runtime depends on the system and the pack. A healthy 5Ah pack can cover many residential pull-downs when the lines are dry. Tough jobs may need a second pack. Track your own times in your area to set a repeatable plan.
Is the CDC30 really strong enough for day-to-day work?
Yes, within its class. The 30 L/min flow and two-stage design give you the control you need for split systems and many light commercial jobs. For huge line sets, a high-flow corded pump is still the better choice.
Can I use the CDC30 on R32 systems?
Yes, when you follow safe methods for A2L refrigerants. Let in fresh air, remove ignition sources, and follow site rules. The pump is designed for this class of work. Your safe work plan remains essential.
Which batteries should I use?
Choose the platform you already run across your tools. Milwaukee M18 and Makita 18V are common. Keep packs cool, charge with maker-approved chargers, and rotate them by number for even wear.
How does cordless change my set-up?
You place the pump beside the unit rather than near a distant outlet. That often shortens hose runs and reduces internal volume. The result can be faster pull-downs and a neater work area with fewer trip risks.
