Can anyone recomend a good filter for spray booth that wont make my gaffer cry ! Lol
We had a pretty good devilbiss one but its about 10 years old and needs changing so had a little look and not found much.i know ya gets what ya pay for but my gaffer aint gonna spend £300 on a filter ! £100 then he will i think,anyows if theres anything over here in uk that you guys use and does a good job then im all ears,thanks carl.What kind of filters?Intake, exhaust etc
I do appologise mate,air line filters.
We have one of these for each booth http://www.autorefinishdevilbiss.com/Division/DeVilbiss/AirControlandFiltration/DAD500%E2%84%A2.aspx
Sharpe, sata,also make them.Very good filter mate but my gaffer just will not spend that sort of money,he will redo several cars tho ! Its like banging my head up a wall but its not my shop mate.
Any other suggestions ? Also home made air line coolers,a link to a home made cooler would be great,heard about them but not seen any,thanks carl.The one Jay linked to is the minimum needed for any paint shop. anything less that that wont cut it
I know mate its just convincing my boss,he says “weve never had this problem before ” regarding water breaking thru our filter but we havent really had a summer over here in uk like this summer as its been quite warm for a few months and really humid,plus we have took on 2 other guys so compressor is getting a bashing,he just dont get it when i tell him we need a better filter system :chair
I feel like buying one myself im that p1ssed off ! What do ya do tho ? Carl.How much time will the desiccant last in a production environment?
What about connecting 2-3 water separators on the line in different places.. will that help..
I have a water separator and filter directly on my compressor and have one on my gun.. never had any problems.. the weather is humid and hot so it is like in the UK..[quote=”martinMK” post=33071]What about connecting 2-3 water separators on the line in different places.. will that help..

How often do you spray? I ask because a separator at the compressor does little good if any. The air needs to cool so the H2O can condense. A minimum 25 feet of pipe is required before the first filter. I don’t see how you can push an inadequate system to the limit in a production shop and maintain system efficiency.1-3 cars/bikes per month..
Do you suggest that I move the water trap further from the compressor?
My compressor is new and does not spew out oil.. but I get quite in my water trap.. Maybe like in the video adding a condenser coil and then the water trap will help?
It was just a suggestion.. I see a lot of people adding water traps on their lines and get excellent results with their air. So maybe all you need is 2-4 water traps that will dry the air and will cool until it reaches the gun?[quote=”martinMK” post=33073]1-3 cars/bikes per month..

That’s why you have so much water. I’m not high production and only double your demands. I have 50 feet of 3/4″ pipe with two drain legs in route before a Devilbiss QC3 and have no water problems. I never use filters on my gun. If your production increases you need the one Jayson and Ding suggested. Read this: http://www.sharpe1.com/sharpe/sharpe.nsf/Page/Air+Piping+LayoutWere a small but busy shop and spray about 3 to 5 cars a day,but these are 1-3 panels only and hardley ever do completes,say 2 every 6-12 months.we have about 15 foot from compressor to filter but only had water troubles in the last month or so,compressor is 12 months old but it gets a bashing from 3 body guys either priming painting or using the da so never gets time to cool off.my gaffer wants another compressor now for the air tools but we only have one supply of 3 phase so we can only run a single phase if we get another.but as i keep telling my gaffer the filters he has are fecked and we need good fitration whether or not he gets another compressor.
As a stupid knee jerk reaction he bought a new cheapo filter and a cheapo filter regulator but as im the only painter to use a gun gauge i pointed out that when i set the wall mount to get 2 bar at the gun it surges up at first then falls down to 1 bar :headsmack:
I cant win and they seem to take little notice of me and the other work collegue giving advise.is the surging because its supplying the first filter then supplies the second and when it empties the second the first wont flow enough air again or am i wrong here,im totaly pissed of with it now !I keep reading about people saying that a filter/seperator at the compressor output is no use. But my own experience – although in a DIY environment – goes against this. The water collects in the at compressor filter/seperator and I get nothing whatsoever in the filter/seperator regulator further down the line. When air is compressed inside a vessel and it is released from a small orifice and vented to a low pressure environment it cools down rapidly. I learnt this at work as we make high pressure air systems. So I say put the filter/seperator at your compressor and keep your pipes clean.
scoobycarl, is the surging more like the gauge reads say 40 PSI then when you pull the trigger it drops to 30 and stays there? Or is it that you pull the trigger and it rises then falls?
