Design
TFF is made from galvanized steel sheet with powder colour coating. The product consists of the xed part with xing
springs, equipped duct connection, the valve seat and the movable valve front plate. The front plate is held by the
central thread bolt and can be moved by rotating. So the gap between the plate and the seat can be adjusted to set
the required air ow volume.
