Direct Drive Negative Pressure Fan 540rpm With Huge Wind

Less Investment And Low Energy Consumption With Direct-Drive Negative Pressure Fan

Ventilation and cooling principle:

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.

1) less investment, low energy consumption. The same refrigeration rate, a one-time investment of about one-sixth of the air conditioning, operating costs of about one-tenth of the air conditioning;
2) cooling effect is remarkable, the temperature can be reduced to about 28 degrees, consistent with the human body temperature, if the water with the water wells as a source of water tanks better, can be compared to the effect of air conditioning;
3) air is fresh and moist, air cleanliness up to 99 per cent.
