Duct fan KV-K 250

Fans of the Belarusian Plant of the producer. The quality is excellent compared to Chinese ones. Very powerful. One is enough for a large square. There is KASPI RED! Maximum air flow [m?/h]1080 Power supply V/F/Hz220/~1/50 Power consumption [W]155 Operating current, A0.9 Speed, rpm3119 Noise level (to the environment), dB(A) 53 Weight kg 5.2 Description KV-K series fans are designed for installation on round air ducts. The equipment provides pressure drop in the lines of ventilation and air conditioning systems, air supply to the serviced premises or air mixture suction from premises or separate zones. The devices are equipped with impellers with backward curved blades, combined with the outer rotor of the drive motor. Motor-wheels come obligatory static and dynamic balancing. To ensure the reliability of the fan as a whole, the motor is protected according to IP44 class, has a built-in thermal protection system with automatic restart. It is possible to smoothly control the performance of fans (changing the speed of rotation) in a wide range. For this purpose, external AC voltage regulators are used. In the design of the fan only high quality materials. The impeller is made of galvanized steel (with polymer blades for some models). The case is made of composite material, which provides high mechanical strength, resistance to corrosion and impact, improved thermal insulation and a significant reduction in the operating noise level of fans
