Low Investment And Energy Consumption Negative Pressure Fan System

In terms of design, negative pressure fans are usually made of durable materials to withstand harsh environments. They often have a large impeller and a powerful motor to ensure strong air extraction capabilities. Some models may also come with adjustable speed settings to meet different ventilation needs.

Advantages of negative pressure fans include energy efficiency, low noise operation, and easy installation. They can significantly reduce the need for air conditioning in certain settings, saving energy costs. Additionally, they help to maintain a comfortable and healthy working or living environment by removing excess moisture and pollutants.

1)12-speed rotor with ball bearings for high performance and low noise.
2)High-density galvanised protective mesh, not easy to rust, high safety factor.

3)waterproof and dustproof shutters, air flows smoothly

4)Thickened steel plate painted T-frame makes the whole machine more compact and stable.
5)Built-in hammer, solve the problem of traditional machine can not be natural ventilation after power failure, boot louvre automatically open, shutdown louvre automatically closed.
