Making your home or building comfortable depends on getting the heating, ventilation, and air conditioning (HVAC) just right. Our Air Balancing Hood and Flow Hood Australia help ensure even airflow throughout the space, eliminating hot or cold spots.
Designed for precision, our laminar flow hood options provide accurate airflow measurements, helping you optimize system performance. Featuring HEPA filter compatibility, they effectively capture airborne particles for improved indoor air quality. With a well-calibrated filter face, our hoods maintain consistent readings, ensuring an efficient vertical laminar airflow distribution.
When your HVAC system is balanced, it not only feels better, but it also uses less energy. This means you'll save money on your energy bills while still staying comfortable.

Measure air volume at diffusers and grilles with confidence using professional air balancing hoods and flow hoods from Testo and TSI. This range is built for TAB contractors, commissioning agents and HVAC technicians who need fast, accurate readings for commercial buildings, healthcare, education and high-end residential projects across Australia.
An air balancing hood – sometimes called an air capture hood or flow hood – sits over a supply or return grille to directly measure the volume of air in litres per second (L/s) or cubic metres per hour (m³/h). Instead of guessing from velocity readings alone, you see the actual air flow being delivered into the space, so you can tune the system against design values or commissioning requirements.
In a typical commercial building, HVAC can account for a large share of total energy use. Getting supply air volumes right helps avoid hot and cold spots, pressure problems and wasted fan energy, while supporting indoor air quality and comfort targets. Correctly balanced systems are also easier to document for compliance and building tuning projects.
TSI’s AccuBalance hood systems are a TAB industry benchmark, designed to take direct air volume readings at diffusers and grilles with a detachable micromanometer and optional probes. Our TSI range includes:
The Testo 420 is a lightweight, battery-powered flow hood with interchangeable hood sizes, ideal for sites where you’re moving between diffusers all day. HVAC Shop stocks:
Air balancing hoods are most effective when used with other test instruments. Many technicians also pair them with humidity and temperature meters, differential pressure meters and Bluetooth smart tools for logging and reporting. You’ll find these in our broader test & measurement collection.
Not sure which hood or kit is right for the job? Use this quick guide, then review individual product pages for detailed specs and hood sizes.
If you’re unsure which hood suits your typical projects, contact our team with your project type, diffuser sizes and any compliance requirements, and we’ll walk you through the options.
A typical test, adjust and balance (TAB) or commissioning workflow might include:
Balancing airflows this way helps maintain consistent temperatures, better indoor air quality and more predictable energy use – all key goals in modern Australian commercial buildings.
This collection has been curated for professionals who rely on precise airflow data:

A vane anemometer measures air velocity at a point and requires you to calculate volume flow based on the grille area and velocity profile. An air balancing hood (flow hood) captures the full flow coming through the grille and reports volume directly, which is usually faster and more repeatable for TAB work – especially on swirl or multi-slot diffusers.
Ideally yes. Matching the hood footprint to the diffuser or grille size helps minimise bypass leakage and measurement uncertainty. That’s why both TSI and Testo offer multiple hood sizes and frame kits, so you can match common 600 x 600 mm, 300 x 1200 mm and similar formats used in Australian ceiling grids.
Most air balancing hoods are designed for single-person operation, especially when paired with lightweight frames or telescopic stands. On some sites, a two-person setup may still be safer or more efficient depending on access, ceiling height and WHS requirements. Always follow site safety rules.
Testo and TSI publish detailed accuracy specifications for their flow hoods, typically including overall volume flow accuracy and operating ranges. Instruments are supplied with calibration certificates, and many users schedule regular recalibration to maintain traceability – especially for compliance and certification work. Refer to each product page and manufacturer datasheet for exact figures.
Yes. While these instruments are common in commercial TAB and commissioning, they are also useful for diagnosing tricky residential ducted systems – for example, confirming supply volumes to bedrooms, studies and living areas when occupants report comfort issues. Just ensure the hood fabric and frame are suited to the grille sizes you’re working with.
In addition to a flow hood, many technicians carry vane anemometers, differential pressure meters, hygrometers and Bluetooth smart tools to log temperature, humidity and pressure. Together, these give a more complete picture of comfort, air quality and system performance.
