How to Install an Automatic Air Compressor Drain From Harbor Freight?

Answer 1

When you get yourself an automatic air compressor drain from the manufacturer called Harbor Freight, you may notice that the manual of instruction that it comes with says that it has not been designed for an air compressor that comes with either a copper or an aluminum tubing for unloading, and it will not work with an air compressor that comes with a pressure operation of greater than 100 PSI. However, these restrictions may potentially be overridden by a few simple steps.

1. Check out the instruction manual once more.
2. Take out the pipe for unloading from your compressor. Get a marker and make a note on the knurl of your T where you plan to make your cuts. You should be sure to leave enough room for a two millimeter flange and enough room that you can clamp your flaring tool on the pipe for easier holding.
3. Take a drill bit measuring out to a quarter or an inch and further enlarge nuts present on the T meant for compression.
4. Take out the nut used for compression that you just enlarged on the pipe and thread it so that it heads towards the opening and use this to make a flange. You will require the flaring tool to create the flange.
5. You will want to double check you flanged your pipe across the T that represents the male end and that it reaches the knurl. If it does not do this, you will need either a swaging tool or an awl from a carpenter so it can fully enlarge all the way down.
6. Keep making your flanges as you will require them, and then you can assemble the pipe for unloading, allowing it to be secured within its position between the compressor and its pressure switch.
7. Take the end of the copper pipe and connect it so that you can automatically drain your assembly. There may not be enough height for your valve to drain effectively, so when this is the case, you can attach a brass angle to the tank before you attach the valve. This will allow you to avoid the bottom access.
