BDTX 355 B MID

The case and fan are made of high quality galvanized sheet metal which is pressed against corrosion. All models have an external rotor motor with a closed structure and have air transport at max. 40ºC. On request, the motor can be produced as thermally protected against high temperature. The terminal box and mounting legs aresupplied with the product as standard. Suctionand discharge nozzles are compatible with ductdiameters and can be connected by clamp.

Designed to work between round ducts. The fanblades are aerodynamically curved and provideregular flow. The fans are composed of backward sloping and infrequently arranged fins.

The rotation of the fan on the motor housing savesefficiency and space. It works at optimum soundlevels while providing strong air suction. It can beoperated in any position. If necessary, it can bemounted on the wall thanks to the mounting legs. Speed can be adjusted with speed control devices.

Optional control devices can be provided.

* Linear voltage regulator speed control can bedone. (see BSC accessory)

Round duct fans are used in low and medium volume ventilation requirements in duct systemswhere the application area is limited. It should beused with oil holding filter in oily environments.
