How exciting to find that someone has already torn-down this eact sup pump! I am so appreciative of the interior photos. My goal is to reduce the noise output from my Puffer Pro, and I am wondering how much space there is inside the case to potentially line some of the interior plastic surfaces with a self-stick “mass loaded vinyl” sheeting… It might be that I’ll have to apply it to the exterior for the best coverage. Does it appear to be that case that the only air inlet for the machine is via the “deflate” nozzle? I wonder how they deal with the machine over-heating as there does not appear to even be any ventilation holes.
