About 3 months ago I bought a 60 gallon Husky air compressor. Yesterday I was using the D/A sander for about 2 hours. I have installed metal piping in the garage with two drops, then an air filter at the end of the piping. I realized yesterday that the compressor made a funny noise whenever I hit the air trigger on the D/A sander...what is this noise? It isn't from the motor, because it also occurred when the motor wasn't running. I also realized that some water was getting past the air filter. My theory is that because the metal piping was becoming warm from the air compressor running every five minutes, that the water wasn't condensing as efficiently in the pipes before it reached the air filter...thus not all the water was removed from the air. I have never had this problem before, usually all the water is removed from the lines ()then again I have never used the air compressor with a sander for this long before). My concern now is that when I eventually start priming/painting the car, the compressor will be running quite a bit, which will in turn cause the pipes to warm up and the result will be water in the air lines.

My solution is to buy one of these http://www.tptools.com/p/74,113_1and...ir-Filter.html, and install it after the air filter I already have installed - will this solve my problems? Please, I need help guys.

 

Water will be your # 1 concern. That filter will help alot. Install a water trap at the compressor and that one you posted at the end of your air line (before your gun hose) when you spray. MotorGuard makes hose-end filters that mount on your spray gun. G/L

Two tips. Face you "T" take-offs up. Second, run the main line slightly downhill away from the compressor, and "T" down to a drain valve.

 

Don't know how you ran your lines, but the air out of the tank should use the port at least 1/2 way up or at the top of the tank.
There should also be a drain at the very bottom of the tank to drain water at least daily if used a lot. There are auto drains available for just that.

I have used a Binks similar to this since the early 70s' (with replaceable elements) as well as the small inline at the gun.

Never had any contaminants of any kind in the paint.
Moisture is also bad for air tools.

Sounds expensive now, but puke some moisture over your final paint and you'll wish you had one

 

There is lots of good info all over the net as to how to run the lines. You have to run at least 12' pipe between the compressor and the water trap. You must give the air time to cool down and allow condensation before it hits the water trap, otherwise the moist air will go thru the trap and then condense in the line ....

If you're in a humit area (like FL) you can run the pipe thru a bucket of ice and water to cool the air before it hits the water trap.

A Devilbiss "snake" moisture eliminator worked great for me - I used that in addition to two water traps and two filters..... overkill maybe .... but it worked

As for the funny noise: check the oil level

BTW, the air inlet filter that comes with the compressor is way too small and is plugged after a few hours.... because of the restriction the compressor can run very hot.... not good.....

Doubt if opinions have changed much in couple of months.

Here's another good thread

Looks like he got some great advice in the older threads..... without a profile we have no clue where he's located....
Stinger: fill out your profile

I have tons of water in the tank and in the line when I use the compressor. I have to drain the lines and the water trap otherwise water will make it to my dessicant snake (which is designed to remove moisture, not water).... this is FL, here you need a dryer on the air inlet side....

 

Mybad79, dod you use just one coffee filter over the funnel? What about the wire mesh....did you glue than to the inside of the funnel as well? Is the filter just taped to the funnel?

Thanks

I cut the wire mesch round so it would sit right at the end of the conical funnel. You can glue it to the funnel but you don't have to. You can use one or two coffee filters, two layers of filter material still flow more air than the crappy stock filter (which is 1.5" diameter?)...

The filter is just taped to the funnel - makes replacement easy

 

Here's an air filter for ya..............................
