PVC Compressor

Compressor with a PVC pipe receiver - this is really possible! Surely none of the masters will argue that the compressor in the workshop is simply irreplaceable. For these devices today produced a lot of improvised tools. Yes, and economically it is more profitable than electrical equipment. For a small workshop usually take ready-made compressors based on the amount of equipment involved, and the average intensity of its use. By calculating the amount of air consumed, you can also calculate the power of the compressor unit. Our today's home-made product is a little-quite a full-fledged compressor. Of course, it is unlikely that it will replace the main compressor unit, but as an additional portable device it will fit perfectly. Later we will see what she is capable of. So let's start!
Compressor from PVC pipes

A brief description and working principle

At first glance, it seems that this is not a serious matter, because plastic pipes do not withstand high pressure. In fact, it will not.As warned by the author of the homemade product itself, the safe working pressure should not exceed 3 bar or atmospheres. Two electric compressors of an oil-free piston type are supplemented by two receivers made of closed plastic pipes interconnected. From the end of one of the receivers there is an output of a quick-detachable adapter for an elastic air hose. The unit is powered by 12V battery. Manual shutdown.

We select the necessary materials and tools

The material base for this device is as follows:
  • PVC pipe with a diameter of 110 mm;
  • Four external PVC plugs for receivers;
  • Standard pressure gauge;
  • Oxygen hoses;
  • Spiral hose with quick coupler;
  • Compressor nipple - 2 pieces;
  • Nipple from an old bicycle chamber - 2 pieces;
  • Ball valve with the transition to the quick-connection;
  • Automotive compressor for tire inflation for 12V - 2pcs;
  • Segment boards for the bed;
  • Several strips of metal for the racks under the receivers;
  • 2 or 4-contact button-switch;
  • Fum-tape, glue for PVC, heat shrinkable tubes;
  • Hardware: clamps, bolts, nuts, screws,washers;
  • Spray gun with spare needle-nozzle for testing the unit.

We put our receivers in cuffs, and connect the fittings with oxygen hoses. Connections with fittings fasten to the clamps.

Try on the compressors at the installation site. You must make sure that they fit freely on the stand and do not interfere with each other. We disassemble them in order to connect in parallel. Solder the contacts with a soldering iron. We use for this native cable from compressors.

We assemble the compressors anew, and fix them on the frame with self-tapping screws. To reduce the vibration of their work, you can additionally glue their bodies with double adhesive tape.

We remove the button-switch from the side of the compressors, closer to the nipple junctions, solder the contacts, and glue the button to the stand on the hot glue.

Testing the operation of the unit

After all connections have been made, you can connect both compressors with their regular hoses to the nipple connectors. By connecting the battery to 12V, we can make a test run and check the operation of our collecting device on the pressure gauge. Do not forget to close the ball valve before this. We insert a spiral hose with a spray gun through the quick-detachable connector, and enjoy the work of a self-made compressor unit. Good luck to all self-made!

Practical Tips

Do not forget about basic safety precautions when working with even such a compressor unit. It is necessary to constantly monitor the allowed pressure, not allowing the excess, otherwise the receivers can simply break. In this assembly, the electrical circuit provides for this to be done only in manual mode. All connections, threaded or adhesive, must also be carefully checked for tightness. Any air etching, especially from the end caps, can lead to a breakdown of the adhesion of the adhesive joint and its subsequent depressurization. As the shells of all components - compressors and receivers are plastic, avoid installation strikes in order not to disturb the integrity of the fragile plastic.
Choose PVC pipes as thicker as possible,since their lifespan will be longer.

Despite the fact that such equipment does not claim to be a prof. tool, it can be used for applying paint or varnish spray. It is also possible to do dust-free workplace without spending the power of a conventional compressor. And for airbrushing such a device will probably be more convenient than a bulky staff compressor. It weighs a little, so for field conditions it is the most suitable equipment. In any case, it deserves the title of technical home-made, and will be able to help out in the absence of the main tool.
