The most efficient way to pipe an air compressor system is with cold water PVC pipe. PVC is inexpensive, easy to cut with a hacksaw, and you can buy any configuration of fittings. Many companies run PVC air lines through their factories. From there they branch them off vertically with feeder lines to provide air to individual workstations. You can run lines in your own garage in one afternoon.

Things You'll Need

  • Female brass air coupler
  • Coil hose, plastic, 24-inches
  • Two PVC pipes, 3/4-inch, 10 feet long
  • Hacksaw
  • Two 90-degree, 3/4-inch elbows
  • PVC Glue
  • One 3/4-inch female "T"
  • Hacksaw
  • Three 3/4 to 1/2-inch threaded couplers

Video of the Day

Screw one 1/2-inch female brass air coupler into the air compressor's outlet valve. It should be sticking straight out from the front of your air compressor.

Lay the 10-foot pipe on the floor. Glue a 90-degree elbow on both ends. Cut the pipe in half. Glue a "T" coupler in the middle. Glue the pipe back together using the "T" as the coupler.

Cut three pieces of pipe at 36-inches. Glue a 3/4 to 1/2-inch threaded adapter to the ends of all three pieces. Screw a female 1/2-inch brass air hose coupler to each of the adapters. Glue the other ends of the pipe onto the 10-foot pipe onto both ends and the "T" in the middle. You should be looking at a "m' shape on the floor.

Lay the assembly in the rafters with the feeder lines extending vertically. Hook individual coil hoses to the ends of the brass air hose couplers.

Hook a 24-inch coil hose to the front of the air compressor. Hook the other end to the line coming down from the rafters. Turn on the compressor to fill the line with air.

Tips & Warnings

  • The measurements are for examples. You can run longer lines. Run them around corners or up the wall. Use zip ties to secure the lines in the rafters, or along the wall. Steel pipe can also be used, but be prepared to pay more and have an increased likelihood of air leaks.
  • Don't exceed 110 lbs. Air tools don't require that much pressure.
