Can the inlet and outlet of Roots blower be common?

No. According to the query of the use specification of roots blower, the roots blower needs to be customized for its upper in and lower out. The upper in and lower out of roots blower are mostly intensive, so the inlet and outlet of roots blower cannot be used universally.

Roots blower is a positive displacement fan, with impeller end face and fan front and rear end covers. The principle is a rotary compressor that uses two blade rotors to make relative movement in the cylinder to compress and transport gas.

The inlet and outlet of Roots blower cannot be used universally because their structures and functions are different.

Roots blower is a gas compression equipment with the impeller as the main structure. It can squeeze the compressed gas by rotating the impeller to increase the gas pressure and discharge it. Among them, the gas entering Roots blower needs to pass through the air inlet, while the gas discharged after being compressed by Roots blower is discharged from the air outlet.

Although the air inlet and outlet are both used for gas inlet and outlet, their positions and cleaning requirements, sizes and shapes are different. If the air inlet and outlet are used together, it will lead to problems such as poor gas flow, increased energy consumption, and increased failure rate. Therefore, the air inlet and outlet positions of Roots blower should be allocated according to the use requirements and product instructions.

Positive pressure use:

In this case, the main application is the fan outlet - blow

Negative pressure use:

In this case, the main thing should be the air inlet - exhaust of the fan
