Description
Mastercool 90068-2V is a trade-tough 8 CFM, two-stage vacuum pump that pulls down fast to a 15-micron spec. Dual-voltage, compact, and loaded with service-friendly touches, it’s a ripper choice for techs who want fewer re-evacs and less mucking around between jobs.
Key features & trade benefits
- Two-stage rotary vane (8 CFM) — deeper vacuum than single-stage pumps, helping you dry systems properly and cut call-backs.
- Gas ballast valve — reduces moisture-related oil contamination, keeping performance steady on humid sites.
- Manifold isolation valve + 3 ports (1/4″ MFL, 3/8″ SAE, 1/2″ ACME) — isolate the pump for decay tests and hook up the gear you’ve already got.
- Big sight glass, front fill & angled drain — quick oil checks and clean changes so you’re back on the gauges faster.
- Thermally protected motor (3/4 HP) + cooling fins & high-volume fan — built to keep its cool on long pulls.
- Field-replaceable cartridge (90168-B) — refresh the business end instead of binning the pump.
- Lightweight reinforced base — stable setup on rooftops, scissor lifts and tight plantrooms.
Why this pump matters on real jobs
On a sweaty Sydney arvo with a deadline looming, you want a pump that just works. With the 90068-2V, you spin on a 3/8″ evacuation hose, crack the gas ballast to purge, and watch microns fall. Isolate with the built-in valve, confirm a tidy decay, charge, and you’re off before peak hour. She’ll be right.

Pro tip
Warm, fresh oil pulls deeper. If your micron reading stalls, isolate the pump with the manifold valve, run the gas ballast briefly to vent moisture, then reseal and continue. Swap oil if it’s cloudy — cheapest performance boost you’ll buy. No worries.
Compatibility & system info
- Applications: Domestic & light-commercial HVAC/R evacuation, automotive A/C service.
- Inlet ports: 1/4″ MFL, 3/8″ SAE, 1/2″ ACME (fits common R134a service hoses).
- Electrical: Dual-voltage 110/220 V, 50/60 Hz. Ideal for AU 230 V sites.
Built for Aussie conditions
From humid Brisbane plantrooms to summer rooftops in Sydney, the cooling fins and high-volume fan help keep temps in check during long evacuations — fair dinkum workhorse behaviour.

FAQs
Will this hit 15 microns in the field?
Yes, when paired with large-bore hoses, fresh oil, cores removed and a micron gauge at the system. Depth depends on system condition.
Which hose size is best?
Use 3/8″ evacuation hose direct to the pump for faster pulls and lower restrictions.
Do I need to isolate for a decay test?
Yes — use the built-in manifold valve to isolate the pump, then watch the rate of rise with your micron gauge.
