Radial blower GRK R 31 / 4 D 4 pole, size 310

Plastic radial blower. High-pressure fan for industrial applications. Suitable for the promotion of corrosive and acid-like media. For easy and direct installation on a pipe system. Low noise level and high efficiency. The engine is located outside the air stream. The engine base made of epoxy coated steel sheet, for fixing the fan, is included in the delivery. Plastic housing. Standard alignment for case LG 270 °. Suitable for temperature ranges from -15 ° C to + 70 ° C. Radial wheels with reverse curved polypropylene shovels. Rotary current motor: Asynchronous current motor. Protection class IP55. IE3 engine. Type of operation S1 (continuous operation). Speed control with frequency inverter. Permissible frequency range for speed control with frequency inverter 20-50 Hz. The temperature in the fan engine is monitored by cold conductor. The cold conductors must be connected to a discharge system that permanently separates the fan from the net at too high temperatures. Electrical connection: connection in the clamping box on the motor.
