Fan Powered Variable

Description

The FPV, variable volume fan powered air terminal unit, is essentially a single duct terminal with an integral fan chamber mounted on the side (in parallel) to the primary air stream. The integral fan chamber contains a fan and induction port. The fan does not continuously operate, therefore, the primary air chamber and the fan chamber are separated by a back-draft damper to prevent flow of conditioned air into the fan chamber, plenum space and backward rotation of the fan motor. The FPV is lined with insulation to provide sound absorption and thermal resistance.
