FILTERED DUCT FANS
BSH-C
Device Components and Material Properties
The BSH-C double suction centrifugal box fan housing and fan are made of high quality galvanized steel that is resistant to corrosion. 25 mm stone wool was placed between the panels. Carcass structure is made of aluminum profile. Asynchronous motor belt pulley drive system is used. The device is capable of handling air at max. 40ºC.
Benefits
Rock wool insulation provides silence. The position damper is opened and the other damper is switched off so that the position of the device is desired and the special damper is not used during normal use times.
Fan Structure
Double suction, backward curved high pressure radial type fan. The fan wheel is manufactured from high strength resistant welded steel and streamlined to provide regular flow. Thanks to the suitable aerodynamic wing structure, it works silently.
Speed Control
Optional control devices can be provided. Speed control can be done with linear voltage regulator in 1~phase products (see BSC accessory). Speed control with frequency inverter can be done in 3~phase products (see BSC-F accessory)
Usage Areas
It is used for supplying fresh air to the shelters. They can be used in two different positions: normal time and war time. In normal time, the air is passed through the G4 filter only to the interior. In the time of war, fresh air; It can be sent to the interior by passing through the activated carbon filter and nuclear hepa filter which can purify the possible chemical (nuclear) gases.
