Features

FRP Negative Pressure Fan

The whole machine is designed with CAD/CAM, which has low investment costs, large air volume, low noise, small energy consumption, stable operation, long life, high efficiency etc.

The louver window is automatically closed to dust, waterproof, beautiful and generous; it can be blowing and winding, which is the best choice for modern workshops to cool down and ventilate.

The cooling principle

The negative pressure fan is the use of air-to-air-to-flow and negative pressure air-replacement principle. The opposite-door or windows naturally inhale fresh air from the installation location, and stuffy gas indoor  is quickly forced out of the room. , Any poor ventilation can improve, and the cooling effect can reach 90%-97%.

Structure

Quoting IP54 and F-Class insulation fan special aluminum-shell motor are produced by foreign advanced technology. It has a lack of overload protection, long service life, stable operation, and small noise.

FRP horn -shaped negative pressure fans mainly include 3 leaves, 5 leaves, 6 leaves and 7 leaves,  The material of the wind leaves mainly includes three types of die-casted aluminum alloy, engineering plastics (nylon and fiber), and glass fiber reinforced fiber reinforcement.
