Fans ВР 5-35, 5-45 are applied for the stationary systems of ventilating, air-conditioning and air-heating, pneumatic transport in milling room of flour milling plants and for other sanitation purposes.
Fans are operated in the conditions of moderate (У) and tropical (Т) climate of the second and third category of location as per GOST 15150-69. Ifmotor is protected against weather impacts, it if allowed to use fans in the conditions of moderate climate of the first category of location.
Fans may be operated in seismically dangerous zones. Ambient temperature: -40°С to +40°С (45° Сfor the fans designated for tropical climate).
Simultaneous operation of several fans is not recommended without net elements. If fan is operated for suction, baffle is required at an output section.
