How to judge the impeller rotation direction and inlet and outlet of Roots blower?

1. Check the arrow on the belt protective cover. The direction indicated by the arrow is the rotation direction of the fan belt. The inlet, outlet and rotation direction of the fan can be judged from this aspect.

2. Judging from the pressure gauge, the pressure gauge of Roots blower delivered under positive pressure will be installed at the outlet. If there is a pressure gauge at the outlet pipe, it means the outlet, and the other pipe orifice is the air inlet.

3. Judging from the pressure relief valve, like the pressure gauge, the pressure relief valve is also installed at the outlet. There is a bolt hole for the pressure relief valve, indicating that this side is an outlet and the other side is an inlet.

4. Judging from the inlet silencer, the structure of the inlet silencer contains filter cotton, while the outlet silencer does not contain filter cotton

If our Roots blower has only the head and no other parts, then I will judge according to the bolt holes of the pressure gauge and pressure relief valve. When the new equipment has complete accessories, it is easy to judge the inlet and outlet of Roots blower.
