Professional Air Balance

Professional air balance speaks to what is a building air balance and how is a building air balance done.

To air balance air systems using air balance instruments, it is necessary that one understands the operation of the many varied air systems that provide heating, ventilating and air conditioning for today's buildings.

To provide an air balance for a building one must adjust supply and return fan air volumes to meet specified operating parameters.

The air balance technician must set the mixed air section of the various air systems to specified operating parameters.

The air balance technician must adjust terminal devices such as variable air boxes, bypass boxes, dual duct mixing boxes and constant volume boxes to the correct sequencing and air flow.

Last but not least the air balance technician must adjust individual supply air diffusers, return and exhaust air grilles to the correct design flow rate.

At the completion of an air balance the technician must compile and table reports detailing all work done.

To be able to provide an air balance an understanding of these principles must be mastered.
