Circular Air flow measuring and pressure control stations | AHQ type

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.

Application

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.
