General

The R3G355-AM29-71 fan belongs to the class of centrifugal radial fans. A distinctive feature of this device is its optimal design without a casing, providing high output pressure of the air flow. It is widely used in supply and exhaust ventilation and air conditioning systems of industrial and residential buildings and structures.

The use of GreenTech EC technology (with integrated electronics) in its production makes it possible to achieve high output air flow pressure, good noise insulation, and energy savings, which meets modern environmental requirements.

The fan is an impeller with a diameter of 355 mm. The wheel, which has 6 backward-curved blades, is mounted directly on the engine shaft and rotates at a speed of 1970 rpm clockwise when looking at the rotor. Blades of this type make it possible to do without a spiral casing, increase air pressure and reduce air losses.

The principle of operation of the device: air enters the wheel through the inlet pipe and exits through the outlet at an angle of 90 to the direction of suction.

The M3G 084-FA EC motor operates at 200 V, consumes 500 W, provides high fan performance and low noise levels.

The operating temperature range of the device (-25° C – +60° C) allows the fan to operate efficiently in different climatic conditions. Minimum dimensions (case diameter 360 mm, height 148 mm) and low weight of 5.7 kg make it possible to save space and use various installation options.

The device complies with standard EN 60950-1, degree of protection of electrical equipment IP 54.
