Review on 💨 Optimized Motor Guard M-60 Sub-Micronic Compressed Air Filter - 1/2 NPT by Ryan Pollock

You will not receive a broken/cracked unit. I am concerned that Clinton R. Webb (see 1 star review May 23, 2013) may have received this defective unit after I sent it back(?). Anyway, here's a repost and summary of my comment I left on Clinton's #1. excellent rating. Hope this helps others. In January 2013 I installed this M-60 filter and it was leaking. I used 1/2" copper tubing for my air connections/piping so at first I thought I had bad solder, a leak near the filter outlet. Air through that outlet/outlet. So I took it apart again and searched for a After a very thorough inspection I found a crack or defect in the casting in the outlet area. I never expected a new filter to flow like this. Needless to say my soldering was fine and a lot of time was wasted so I am a bit am scratching my head. Revain sent me a replacement quickly and this one is leak free and has no defects. Actually works great. (see update below). If yours is leaking then it is defective and should be returned immediately. Now all I can do is hope that the defective unit I bought in January 2013 was not repackaged and resold to Clinton I spent a lot of time fumbling with a defective filter meln, which I was convinced was "okay". oh someone else wouldn't understand. But who knows. Of course, I had to spend time testing and retesting my connections to make sure they were reliable and not the cause. But just because I had it installed I could see a microcrack in the casting, but first I needed to know where it was leaking. Otherwise you would never know without installing it, so I could see that someone could say it doesn't look defective and try to resell it. A shame, to say the least, if this actually happened. UPDATE 1: I've been using this filter for over a year now and have tested mine to over 150psi. It doesn't leak. Otherwise I keep it constant at 100psi with no leakage. As for my setup, I have the compressor outside the garage in a service building (compressor station) and the duct runs through the basement (about 80 feet) in 1/2" copper. Where the line exits vertically from the basement (lowest point of the run ) and exiting up and down to the garage I have a gas shut off ball valve with a drain cock so I can service/drain the lines regularly Water trap just in front of the Motor Guard M-60 filter This trap seems to catch most of the water (I have to do quite a bit on a daily basis draining a lot of water) before it goes into the M-60 paper filter. Also note that I like to run a vertical copper line after the M-60 filter at least 3 feet to allow gravity to deal with more moisture one last time, that could somehow get through my hydrophobic glove Finally, after a year of frequent use, the M-60 paper filter looks like new I thought I might have to change it , but was pleasantly surprised that it was dry and c UPDATE 2: The water separator I use is effective but I understand its capabilities are limited. The device is a simple cobalt water trap (note: many of those sold on Revain are probably as good or possibly better): 90 psi pressure, 5 psi pressure drop. I think most inexperienced people would expect this water trap [alone] to remove 100% of the water, including steam. You are completely wrong. They typically cost less than $25 and are ineffective on their own. Compare water for $20 and up now. Separator to professional line dryers which are expensive for a reason: They are very effective They are medically very effective for protecting VERY expensive tools and equipment. Get very good results so I recommend a water separator (and any should work better) to remove moisture and then this Motorguard M60. I use it every day with great results: varnishing, sandblasting. even general air drying with Cornwell 4" Blow Gun Kit, $49.95 SKU: CATBGK which I LOVE and highly recommend (I have two: 1 for the shop, 1 for the tool cart). Recommend for professional and heavy use I have a compressed air dryer ($600-$1,500.) For small jobs on site (i.e. not in a shop) such as oil-based painting, I use a built-in dry air filter powered by a portable compressor.These desiccant filters are excellent at absorbing water vapor and preventing fish eyes from appearing in color, however they are short lived and naturally absorb water from the air so if you open them either throw them away after a while or dry them for reuse most of them are marked as single use but with care you can dry them in a low temperature oven and then reseal Finally steam down your expectations ments to 100% laboratory dry lines. Forget about it without expensive equipment. But with the water separator and the M60, you get what most of us really want: a reliable, dry filament that will protect your air tools and deliver great results. For further reading, search for compressed air dryers and dew point to understand compressed air and moisture. Unfortunately, this is a lot more than just plugging in a $20 waterfall trap. Hope that helps.
