How to solve the high noise problem of Roots blowers
Thread Content
There are several Roots blowers in the factory, and their noise level is well above the allowed limits; it does not meet the regulations. How can the noise generated by these Roots blowers be reduced? For those who use rotary vane blowers, please be cautious; it would be best to include a photo if available. Thank you

It’s quite troublesome, but it works pretty well. There are also inlet and outlet silencers, as well as vent silencers – all of them are needed.
I don’t know what the Roots blower at the site of the original poster looks like. The Roots blower I’ve seen was inside a soundproof enclosure, with vibration damping pads. In addition, import and export silencers also serve to reduce noise
There’s no good solution; all that can be done is build a soundproof room.
The Roots blower has excessively high noise levels; the rotor needs to be replaced. Additional soundproofing measures
There’s no good way to add soundproof rooms separately! ! ! ! ! ! ! ! ! ! ! !
This is how we install soundproof rooms.
Is it the noise of the fan itself or the noise at the air inlets and outlets? Rotary vane blowers are somewhat noisy by nature, but if there are abnormalities, it may indicate a problem with the blower itself; silencers can be added to the inlet and outlet openings to reduce noise.
A loud noise level is a characteristic of rotary vane blowers; noise reduction is usually achieved by using soundproof enclosures
First, ensure that the equipment is operating normally (aside from noise issues), such as no increase in casing temperature, no rise in gearbox temperature, no vibration at the bearing locations, no fluctuations in motor current, and no abnormal noises. This helps to rule out problems with the equipment itself. What remains is to reduce noise levels by installing silencers, adding soundproofing materials to the walls of the room where the equipment is located, and requiring personnel to wear earplugs when entering that room
