Lo guys.

Was at one of our customers garages the other week and spotted a paint booth in the corner (a big big one) so i asked if he would sell it and he jumped at the chase and said yes and quoted me a silly silly low price (it came with the garage when he brought it and its not been used in over 10 years, they only service cars now and do not do any form of bodywork)

it measures 28 foot long by 18 foot wide (double entry doors) its jsut over 11 fot high .i had a look inside and its a top draft (it has 4 huge filters in each corner top) they are plumed in pairs going to 2 enormous fans. it also comes with a 14 foot high diesel heater + all the pipe work and ducting same with the lights all in there and it all works. (the only downside is i have to take it all apart and get it back to our unit lol , can see it being a few trips on the flatbed + trailer)

so my questions are as follows:

if i wanted to build the booth back up but smaller are there any issues i should be aware of? (i am only ever going to do small cars like honda crx's civic etc) it means i get to keep more shed space and this should make it cheaper to run in terms of heating correct?
its an old booth and it has those fiberglass matting type of air filters, my local paint factor sells those new cardboard/paper filters are they much better and also how often should i be changing them? (every car painted?. or after every stage?) also i am assuming these take specialist strip tube lights?

is there anything else anyone can tell me regards to using/owning a booth that i need to look into?
i have not looked at things like how it is wired up (weather all the connection boxes are sealed/air tight, same with the light boxes weather those are also sealed/airtight)

Thanks!

Does it require three-phase power (for the fans)? Do you have 3-ph at your location? Keep the diesel exhaust waaay far away from the intake for the booth. With HVLP I doubt you'd need to change the filters every time but someone who runs/works in a shop can better answer that...

nope the fans are single phase (240volt) but i have access to 3 phase as our migs and tigs run on it. the exhaust for the heater heads right up through the roof so it will be a good 30 foot away outside

How much if u dont want it? I use a so called paint room,turns out ok work sometime we have to cut and buff.Ive ran across a few used booths but I still thought they were a bit high mostly the cross draft.I would have to put in another stall and most of my customers are broke they want stuff painted for nothin,anyway if its single phase wiring you are lucky most are three phase anyway good luck...

Even in a production shop the filters are not changed that often, when you see problems or reduced flow change them, it has an air makeup unit which you need for water born these days, but the problem I can see is flow and air change is calibrated to the type of booth or size, booths are modular so their is no problem resizing it but I would contact the manufacturer and see hat the flow should be and how to get this right, you want positive pressure.Diesel fired you may ant to change that to gas in the future, ho much did you pay for it?I have disasembled booths and their are alot of carriage bolts to remove.
good luck.

We use these filters for exhaust in both of our booths http://www.joyfilters.com/Paint-Pocket- ... lters.html and I can get 2-3 weeks out of them and our booths run 40-50 hrs a week.With the old fiberglass filters we would only get 3-5 days.Your intake filters should be changed 6-12 months for the high quality viledons.

i went and got it today.

it was only £600 and the guy that lets me have the unit paid half and is transporting it back for me. the fans are 3ph (they are bloody enormous and in a load of undergrowth, but they do work) we have some single phase fans at our yard though that we used in our makeshfit polysheeting booth.

would not be to bad taking all the ducting off today but everything is seam sealed together, and it was touching 36c in the roof of the garage so it was sloppy and stickey has hell.(not to mention the dust, i was black all over by midday, had to put the dust mask on it was that bad, 30 years of garage crap about a cm deep) it was only used a few times 30odd years ago but they guy tat lives next door complained about the smell and they used it as a storage area from then onwards.

its actually a rear draft booth the venting ontop is all for the heating, it also has normal fiber filters on the doors. everything works which is a bonus and its all galv steel. 6 heater ports on the roof, 2 normal large vents on the front and the 2 hugh fan ports on the rear wall, totoal 12 strip lights on ontop and they jsut shine through bonded in tougthened glass (its thick stuff, a good cm deep). will be putting this back in a similar place in out shed (in the corner and seal it into the wall and rear wall)

will probably either re-motor the fans to single or sell them and buy single phase. i can run them off the genny but it adds to cost having that running.

should have it all broken down for Wednesday, just need to finish the floor in our unit lol. never enough time!

jhc this is going to break me at this rate.

upper panels are turning into a nightmare, 6 sections wide and 4 strips deep. each held together by lots of rusty screws and nuts, and made worse by seam sealer lol. got jsut over half off the roof today, left the glass ones as those weight a flapping ton. also the roofing is only around 1.5mm thick so you have to be uber carefull where you stand when up top undoing the bolts.

shame im doing this on my lonesome as i would have had the lot out today including the wall sections.

i have all week but currently thinking it will all be out including the fans late thursday if im lucky.
