Because Roots vacuum pump is a suction pump and needs customers to service atmospheric pressure, it will be more difficult to overcome negative pressure, while the positive pressure blower can use atmospheric pressure to boost the pressure and have a wider pressure range.

2. Which price is higher?

Because the manufacturing of Roots vacuum pump is more difficult, the price of general Roots vacuum pump is higher than that of Roots fan. We can see the quotation of the same model. The price of vacuum pump is often higher.

Roots blower can be used after installation, and the roots vacuum pump may need to be equipped with a front stage pump when starting. The purpose of the front stage pump is to ensure that the roots vacuum pump will not rise to a very high negative pressure, so the front stage pump is required to first increase the negative pressure, and then start the roots vacuum pump to continue to increase the pressure.
