air supply system

air supply system


Stable air supply system for controlled fresh air supply in sanitation and negative pressure areas.

Test setup:

air supply system

1: air supply system
2: air-tight room 1,5 x 1,5 x 2 m
3: negative pressure unit
4: hose
5: PVC pipe
6: measuring point static pressure
7: counter air
8: volume flow measuring device (thermal anemometer AIRFLOW TA430)

Test evaluation

1) Flow rate air supply system (m³/h), depending on the negative pressure (Pa) in the air-tight room (2).
