Harmann RM EC
Radial fan duct with energy-saving motor
RM EC fans are used in general ventilation of living rooms in residential, public and industrial buildings.
The housing of RM EC fans is made of pressed galvanized steel sheet and epoxy painted gray (RAL 7035). The housing has standardized connection pipes with a negative tolerance (nipple) for connection in the system of round ventilation ducts. A junction box is mounted on the housing.
The RM fans are fitted with a dynamically balanced rotor, which is an integral part of the engine (so-called motor with a rotating housing). Shoulders leaning back are made of plastic.
The drive in the RM fans is carried out by a synchronous electric motor, brushless, electronically commutated 230V, 50Hz with integrated thermal protection and motor controller. The motors are adapted to smooth speed control in the full range while maintaining high efficiency. The change of rotational speed is possible by connecting an optional potentiometer or other controller using the analog 0-10V signal.
The degree of motor protection: IP54 (models 100 / 300-250 / 1000), IP33 (models 250 / 1200-315 / 2000).
The degree of protection of the junction box: IP44
The degree of protection for the entire device: IPX4
Insulation class: F
Maximum working temperature: 60-70 ° C depending on the model
