Variable Air Volume

Efficient Variable Air Volume (VAV) Control Unit are Duct mounted pressure dependent bypass type unit, ideal for low and medium pressure applications. These unites are suitable for both cooling and heating system. The temperature can be preset on the electronic analogue/digital thermostat, which senses the room temperature and controls the VAV unit.

The required quantity of air to each zone is pumped in to the area based on the load requirement and the balance air bypassed through the bypass section of the VAV unit above false ceiling or to return air ducts.
