Roof smoke exhaust fans of BPДВ type represent a series of nine standard sizes with air capacity from 1500 m3/h to 90000 m3/h and developed static pressure from 50 Pa to 1100 Pa at a temperature of handled medium 20°C.
PURPOSES OF FANS
Fans BPДВ are installed on the roof of buildings and serve for removal of high-temperature smoke-air mixtures occurring in fire and simultaneous heat release outside buildings and structures.
Degree of fire resistance of fans is 180 min at a temperature of gas-air 600°C.
BPДВ fans are intended for operation in conditions of moderate and tropical climate (version У, Т), placement category 1 under GOST 15150-69. Environmental temperature is from -30°C to 40°C (45°C for tropical version).
