Axial fan for general ventilation systems. Intended use SFL-M axial fans are designed for general ventilation systems as air supply or exhaust fans. The fans are designed to pump clean air in the right direction, depending on the fan version. The devices are adjusted to work inside and outside buildings, both in vertical and horizontal positions. The fans are designed for operation at a maximum ambient temperature of 55°C. The temperature of the conveyed medium cannot be higher than 55°C and lower than -20°C. SFL-M fans are manufactured within a diameter range of 315 to 1250 mm and a power range of 0.55 kW to 55 kW. They are always equipped with PTC sensors, and at the Customer's request they can be fitted with IE4 motors. The fan is designed and adjusted for continuous operation under conditions at the place of installation. It is characterised by a high resistance to the mechanical, corrosive, thermal, and humidity impacts to which it will be exposed during operation. The fans can work both in horizontal and vertical positions. Table 1. Standard dimensions of SFL-M fans Dimensions SFL-M 35 SFL-M 40 SFL-M 45 SFL-M 50 SFL-M 56 Design The fan is made of black powder-coated steel sheet with a plastic or aluminium rotor by default. The design of the rotor makes it possible to adjust the angle when the fan is off, with the prior consent of the manufacturer. It is adapted to work with a frequency inverter. Optionally, the fan can be manufactured with galvanised or stainless static elements. Heavy-duty, three-phase 400 V / 50 Hz motors are used in the fans. The motors are made in accordance with the IP55 ingress protection rating, hold FI insulation class, and use the IC411 cooling method.

Manufacturing versions high efficiency low level of noise SFL-M fans are made in two versions: SFL-M with a rotor made of glass-reinforced, fibre-reinforced polyamide SFLA-M with an aluminium rotor Installation The fans will be installed in the building per valid directives, local and OSH regulations, and according to reference documents such as the Operation and Maintenance Manuals.
