Good day
I'm sharing with you my little project - a silencer box for an air compressor.
Design premise - cheap and functional, relatively small. Will only run for a minute max (don't worry about overheating), to fill a pressure pot. It will live in the house tucked under a work desk.
If not obvious from the pictures, I've starter with the base, where I placed the labirynt for the air intake. Used a carpet off cuts I had available. Once fully closed off, I've placed the springs somewhat evenly to support a plate for the actual compressor. Then I glued the box sides on, finished with the top board to have a complete cube. Cube was then split in two halfs, and I have doubled the walls in the base, to A. provide thicker barrier for the sound, and B. to act as a guide to fit the lid over the box. For supply of electricity, I've just bought an extention lead, switch and a grommet. For the air hose, this was 600mm whip and quickfit connector, which I epoxy glued in place. Last steps was internal padding, and there I called it finished, and ready for use.
How was the result? I don't want to blow my own trumpet, but it was better then I was hoping for. without the box and compressor running, you would have to shout quite hard to be able to communicate. With the box, it's just a quiet talk, as you would like it. You know it's running, but you don't really care that much about it running.
What do you guys thing? Not pretty by any means, but works a treat.
