Leminar Variable Air Volume (VAV) Control units are ideal for low and medium-pressure applications. These units are suitable for both cooling and heating systems. The temperature can be preset on the electronic analog/digital thermostat, which senses the room temperature and controls the VAV Unit. The required quantity of air to each zone is pumped into the serving area based on the load requirement and the balance air is bypassed through the bypass section of the VAV unit above the false ceiling or to return air ducts.
