inline centrifugal duct fan

Shell: Use high quality tensile SGCC and tensile by mold, the surface have been spray processing, has strong ability to resist corrodes, with CAD design flow to enable to be maximum efficiency, Inlets and outlet diameter is design as the same pipeline standard, to easier to install, repair and cleaning

The actual simulation flow analysis, optimal design, Low noise powerful air volume

Use import bearing , low temperature rising and low noise. High torsion force, quickly startup and high efficiency

Junction Box: injection from in flame-retardant fiber PVC materials. Fire performance, security to use, the wiring easy disassembly in the shell outside

Use external rotor motor, runs smoothly and lasting for longtime

Unique fan design, powerful air volume and high efficency

Powder coating sunface and strong corrosion resistance

1. The products have been widely used in air supply and air exhaust in the hotels, conference rooms, supermarkets, stations and airports and other public places

2. RK type direct coupled centrifugal pipeline fan is a new type fan made by the domestic and foreign advanced technical design by our company. In order to be convenient for the air pipe connection, the inlet and outlet of the products have been designed according to the standard, and the two sides can conveniently connect with the air pipe, which is greatly reduce the costs of the pipeline design and production. This series fan has small volume, light weight, small vibration, low noise, long service life, high efficiency, good safety performance, and convenient installation and other characteristics. The products have been widely used in air supply and air exhaust in the hotels, conference rooms, supermarkets, stations and airports and other pubic places
