DAPMH30 from jehmco

the one I have running is pretty quiet so I did a little test and found that the more air outlets I shut off while it was running the louder it became so you may have a bit too much back pressure on it and may need to increase the amount of air outlets or use 1 as a bleeder valve to help relieve the back pressure

I had one until my recent upgrade. I put it on a piece of Poret foam. Quiet and powerful. Great bang for the buck!

I am unfamiliar with that specific model - they all look like they changed since i last purchased one.

Senase is right - use some sort of material to dampen the vibration. I used a piece of old carpet.

Initially when I set up this exact same pump for a friend, there was a noise issue . We then realized that it was placed on a surface that was causing the pump to resonate loudly. We then put a different material underneath it ( I think it was actually cardboard) and then it was fine. I would say first try placing different materials underneath it and secondly make sure it isn't vibrating and hitting any object around it. I hope one of these options can solve your problem. Good Luck!

I just bought DAPMH30 this pump and got it all set up it is so loud anyone have this pump?
