compressor auto drain kitquestion...
beware - these are not good if you pump puts out more than 100 or so
PSI - I tried one, my pump is set to 160 - it blew the little o-ring right through the device and it was totally useless. On the plus side, harbor freight gave me my money back. so my tip is "don't" On Sat, 25 Mar 2006 22:29:20 -0800, "ted harris" wrote: Hello, I just purchased a Harbor Freight auto drain kit here; http://www.harborfreight.com/cpi/cta...emnumber=42221 Anyone got any pictures of their installation job or any tips on installing it?

I just purchased a Harbor Freight auto drain kit here; http://www.harborfreight.com/cpi/cta...emnumber=42221 Anyone got any pictures of their installation job or any tips on installing it? Mine works great... now! But first I had to learn the hard way that the plastic tubing they include can't handle the heat near the compressor. It blew right out of the fitting as soon as it got a little warm. My solution was to replace it with copper tubing to a point about 10 - 12 inches from the drain and then I used a coupling to tie into the plastic hose for the rest of the run because the fitting on the drain valve itself is odd and requires the plastic tubing. It's been working fine for 4 years or so IIRC. I complained to Harbor Freight and they refunded my money but let me keep the kit so I can't complain. :-) My compressor has a 20 gallon tank. If you have something quite a bit larger I'd be concerned that the valve won't be open long enough to drain all the water out but I really don't know whether it would be a problem...

Thanks, Hey Ted, Maybe it won't apply directly to your application, but if you want a REALLY GOOD tank drain, I suggest items from a company called Burkert, or from a Burkert local dealer/distributor http://www.burkert.com/ or http://www.buerkert.com/ Specifically a solenoid valve: http://www.buerkert.com/COM/buerkert_products.php?type=6013A&sk_id=30&show_as= 6013 for the voltage you need, AND PLUS .....the modular timer control for it, for which I have a zillion numbers on the invoice, but can't locate it on the web page using them, so ask the dealer for assistance. Mine is on an 80 gallon vertical DeVilbiss Tradesman model garage style unit. The drain is simple enough, and I have mine on the existing bottom-of-tank drain, outboard of the manual drain valve and fitted with an el-cheapo (Harbor Freight??) quick disconnect, and set to drain the tank for 10 seconds every 6 hours, and it is set up so that works on a 10 seconds on, 5 hour 59 minute and 50 seconds off, which means that anytime the power to the compressor controls (and this timer) is removed and re-applied (ie...the breaker tuned off and on) it "blows-down" at actuation and then starts the six hour cycle. This way, condensation created during compressor operation has time to "run" to the bottom of the tank, rather than only as the tank unloader works. The timer is easy to set in many ways and over a huge timing range. The convenience of the quik-connect is that if I want to "check it" or reset the timing, I don't have to do it on my knees or bent over upside down...I just disconnect it and bring it to work height. Take care. Brian Lawson, Bothwell, Ontario. ps.... for the winter months, it just blows-down into a zorb-all snake, and in the summer (when it is actually doing something!!) it blows out a plastic tube under the garage door. It is quite surprising to me that there is so little blown-down on this cycle, but prior to adding this unit it used to have quite a fair quantity of moisture/crap discharge, when and if I was lucky and remembered to do it manually once a week. Quite a difference! I'm not into painting, so I can't say how much this affects "dry air supply", but I imagine it helps a lot. I think if it mattered more to me, I'd set it to a 5 seconds every hour time. |

compressor auto drain kitquestion...
I did install a similar drain on my compressor but it would only drain when
there was 0 psi in the tank. I have my compressor on all the time so it never drained. When I did stop the compressor and release the air pressure the rust plugged the drain and I had to file it into file 13 (garbage can). Eric |
