RFV ZN
Roof fan
Application
Roof exhaust fans RFV ZN are designed for ventilation of rooms with a low degree of air pollution.
They are used in exhaust installations from apartments, supermarkets, industrial halls, workshops, warehouses, toilets, garages, parking lots, and farm buildings.
Construction
The RFV ZN roof fans have a vertical air outlet. Housing made of aluzinc sheet. Impellers with backward tilted blades: sizes 125, 160 made of plastic, 200, 250, 315, 355,400, 450, 500, 560 made of aluminum sheet.
As standard, fans of sizes from 125 to 315 are equipped with a connection stub for connecting a ventilation duct. Sizes 355-560 do not have a stub pipe, to connect the cable, use P connectors and K connectors. Fans adapted to work in a vertical position on flat roofs, after using appropriate RS roof bases can be mounted on sloping roofs.
Motor
Electric motor made in accordance with the applicable Directives and efficiency classes, marked with the CE mark. The motor is adapted to voltage speed regulation, equipped with thermal protection (TP).
Power supply - three-phase 230 / 400V 50Hz, 400V 50Hz or single-phase 230V 50Hz (depending on the fan model and motor power). Selected three-phase models can be operated in 2-speed mode by using a Y / Δ switch.
