Is there any equipment available for silencing the exhaust from vacuum pumps? And if it’s the pump itself, how can noise be reduced?

There is a project where the client requires noise reduction for the exhaust gas from the vacuum pump. Are there any noise suppressors available? It would be great if you could provide a sample photo of them. How to handle noise reduction for the pump body?
If it is a vent pipe, search for information on the principle of silencers on Youku; they can be made manually based on the pipe diameter, or purchased directly online. This thing doesn’t require much technical skill. As for noise reduction for pumps, if temperature is a concern, glass wool can be used for insulation, or soundproof enclosures, covers, or rooms can be installed. It would be best to send some photos from the scene for easier discussion and reference.
It is originally a vane type, which is a piston pump. It’s loud. You can check to see if it’s loose. Try changing the pin of the coupling.
