Testing and Balancing Pressure and Airflow - Supply Air Flow
There are two components to the supply air, the T�A�B� pressure point and front face air speed� Note that not every model has a perforated front
panel for supply air and only KVF models require a supply duct to be connected� Other models have an optional supply duct connection�
Before measuring airflows check the exhaust and supply fan on and functioning normally� Airflows must be balanced for each damper in each
hood section� It is important for the hood to have a balanced airflow, to ensure exhaust and supply function efficiently�
Using a manometer measure the pressure at the T�A�B� (Testing and Balancing) point� For hood models with
a perforated front panel, use a vane manometer to measure the face air velocity at 50mm from the front
panel� The air speed must be less than 0�6m/s� Do this for each supply plenum�
Compare results to the rating plate� Values must be within ±10% of specified value and the air velocity
must be less than 0�6m/s� If the values are incorrect, adjust the airflows as per below�
1� To adjust to supply dampers (each supply collar has its own adjustable damper), first remove the comfort nozzles
2� Locate the spring inside the supply plenum
3� Twist the spring to increase (anticlockwise) or decrease (clockwise) the pressure as required
4� The bolt on the axle may need to be loosened before the damper can be adjusted
5� Feed the spring back inside the supply plenum
6� Re-fit the comfort nozzles when done
