+7 (4942) 622-023ВР 280-46 medium-pressure centrifugal fan of single direction suction is a blade system, consisting of: impeller, spiral housing, frame (bedplate), diffuser and asynchronous motor (380V, 50Hz), of various rotation speed and power for expanding the range of aerodynamic characteristics. The impeller is “spiked”, has 32 forward curved blades. In regards to the direction of the impeller rotation, the fans can be of right and left rotation. If viewed from the inlet port and the impeller rotates clockwise – the fan is of the right rotation and, conversely, counterclockwise – of the left rotation. BP 280-46 fan has a spiral turning body, which can be installed in 6 positions (from 0? to 315?, with a range of 45?, 180? by special order). BP 280-46 fan is attached to the welded frame (bedplate), which during installation can be mounted on vibration isolators. The number and size of vibration isolators depend on the size of the fan. In regards to to the design, it is possible to manufacture the fans according to scheme 1 (the impeller is located on the motor shaft).
Designation of ВР 280-46 smoke exhaust fans
Smoke exhaust fans ВР 280-46 are used in the emergency smoke ventilation systems. They can have blast protection. These fans are intended for removal from a building of smoke-air mixtures caused by fire. Such fans are capable to work constantly with gases up to 400°С, if their temperature reaches 600°С no more than 120 minutes.
Operation conditions
Centrifugal fans ВР 280-46 ДУ are used to move non-explosive smoke-air mixtures that do not contain explosives, fibrous and sticky materials, conductive dust, corrosive gases and vapors in concentrations destroying metals and insulation, with a dust content of no more than 10 mg/m3.
The fans are designed for operation in conditions of moderate climate temperate (M) (-40°C to 40°C) and tropical (T) (-10°C to 50°C) climate of the 2nd and 3rd location environmental classes in accordance with GOST 15150-69.
For the motor protection from atmospheric influences (precipitation), fans are allowed to operate in a temperate climate of the 1st location environmental class, in accordance with GOST 15150-69.
When using these fans in case of fire, their further operation is unacceptable.
