Method of reducing air compressor noise
A compressor assembly having a tank seal which seals a tank gap between a portion of a housing of the compressor assembly and a portion of a compressed gas tank and a method for controlling the sound level of a compressor assembly by configuring a tank seal to seal a gap between the housing of a compressor assembly and a compressed gas tank. The sound level of the compressor assembly can be controlled by sealing a tank gap between at least a portion of a compressor assembly housing and at least a portion of a compressed gas tank.
1. A compressor assembly, comprising:
a motor having a motor speed in a range of 7,500 rpm to 12,000 rpm which drives a driving mechanism;
