    New compressed air distribution

    I posted a thread in the flatwork project showcase area (http://familywoodworking.org/forums/...ead.php?t=5576) that shows an exhaust fan I built. Of course, after building it, I could not get it to the window so I had to move my compressor and re-structure my compressed air distribution system. While I was at it, I decided to run copper pipe to the other side of the shop. Also added in plenty of filtration, a timer drain that I had not had a chance to install, and a hose reel that I also had not had time to install.

    Nice neat job Mike! I used 3/4" pipe and it is OK but I could never get all of the small leaks stopped completely so next time I am going with copper.

    Looks great, Mike!

    I notice your compressor is elevated on a platform - is that just a 2x4 framed platform with a plywood skin on it to absorb vibration? Are those rubber pads under the feet, also? I'm going to have to do something about vibration with my 60gal compressor and I'm interested to hear about your platform

    Very well installed - I'm contemplating plumbing for air, too, one day

    Very neat job, Mike. I noticed that you did your homework and did the takeoff from the main line with a "T" out of the top too, which is the proper way to do it to further minimize moisture getting into the "Drops".

    Allen,

    My previous setup that I had to change to get the fan to fit into the window was black pipe. It seems like I spent a long time trying to get all of the leaks out. Never did. Finally just gave up and turned the air off at the compressor when ever I was not in the shop. Real pain in the neck. I tested the new setup for leaks by turning the air off at the compressor and it took 4 days for the pressure to drop below 20lbs. I'm happy with that.

    Jason,

    I built the platform for several reasons. First was to provide stability so that the foot print would about twice as big as the foot print for the feet that are built on the compressor. It seemed like the unit would be a tip hazard unless I drilled into the slab floor and anchored the unit. I really didn't want to drill into the slab. With the base, the compressor is very stable and does not have a tendency to tip at all. The other reason was to attempt to isolate the physical sound transmission into the rest of the house when the compressor is running. I really wanted specific vibration isolators but when I priced them I decided that I would just use rubber sheet that I found at my local hardware store. I cut holes into the rubber sheet and put that under the feet of the compressor. I also cut the rubber sheet and but it between the bolt washers that secure the compressor feet to platform. The platform is made from hardwood 3/4" plywood and 2x4 with a cross brace in the middle for strength. I put leveling feet into the 2x4. This allowed me to level the platform since the floor has a small slope to allow for water drainage (builders seem to think that people park cars in these garage areas). Under the leveling feet there is another sheet of rubber. I don't know how much difference this really makes since I never ran the compressor without the rubber sheets in place.
