ASLI Bypass Terminal Unit, model ST6000 is a single duct variable air volume pressure dependent air terminal unit, designed for use with constant volume low and medium pressure packaged air handling systems or roof top air conditioning units. ST6000 handles a constant supply of primary air through its inlet and bypass the excess air through the pressure relief damper into the plenum return when the pressure in the terminal unit increases. The supply air volume is controlled by damper blade which responds to the room thermostat in the occupied space to meet the cooling load.
