Circular Air flow measuring and pressure control stations | AHQ type

The type AHQ...D circular air flow measuring and pressure control station is designed to control the supply duct pressure per zone, to a minimum value that still allows the VAV terminals in this zone to function efficiently, reducing operating cost and noise level.

Productspecifications

Flo-Cross®, high accuracy, centre-averaging air flow sensor.
Static measuring device with 100% repeatability on-site measurements.
Amplified signal, at least 2,5 times, to improve reading accuracy at low air velocity.
The large number of test points (at least 24) ensures a true average measurement signal.
Better than 2,5% accuracy even with irregular duct approach.
Required minimum straight ductwork approach of 1x diameter only.
Compact design, optionally available in double wall construction.
Suitable for large air volumes.
Low pressure loss over the terminal.
Low noise production.
Maintenance free.
