aircompressor and spray gun

 
  NSWGRules Locomotive Fireman

Not too sure if this enquiry should be here or in the Weathering Thread.  I'm wanting to purchase an aircompressor and spray gun for weathering and also overall paint jobs for NSW HO.  - what do you recommend?  I've checked out 'Runway 13' s stock at Liverpool in October 2012 but now see others alot cheaper on ebay?

Is there a difference? - or just stick with what Paasche recommends?

I purchased a "runway 13"  air compressor and spray kit at the Liverpool exhibition last Oct.. No problems and very happy with it. Spare parts and accessories available so watch out for those cheapies on eBay.

When my Badger air compressor died back around 1990 I decided to buy an all-purpose compressor for the shed. I've gone through about 3 compressors since then. I have used them for air brushing (of course), but they are also invaluable for a myriad of other jobs around the shed/house. Having a 25 litre tank with over 100 psi available, I am able to blow the dust out of the air filter of my 4x4, as well as the filters of the house air conditioning system. Then there is the kids bike tyres, as well as the 4x4 and trailer/s.

I also have a couple of air tools such as a 10mm wide belt linisher, die grinder etc.

To avoid having to fiddle with the pressure settings when I want to use it for air brushing, I have used a "T" junction at the compressor's outlet. This leads to 2 different moisture traps, each with a regulator and ON/OFF valve. One outlet is set at around 28psi, whilst the other is set to maximum pressure.

I use "RYCO" fittings exclusively, even on my 4x4's air system.....I have a 7cfm engine-driven compressor on the Landcruiser too, so I can use a dust gun or tyre inflator when out in the sand etc. Of course, that 4x4 compressor supplies the 18 litre tank @ 135psi to operate my set of triple Klein "train horns" too!! That stirs-up wayward pedestrians and lane-changers; not to mention roos and emus etc!!!

Does such a compressor have enough free air delivery to drive the die grinder? I wouldn't have thought so.

Yes it does, but only in relatively short bursts of about 30 to 45 seconds. I then tend to stop working, check the progress of the job and allow the tank to recharge for about the same amount of time. I tend to only use it for small jobs such as elongating a hole etc.

Hi all,

I'm looking into getting an air compressor for my air brush (rather than waiting until I have lots to paint and borrowing one, which is a tad inconvenient) and was hoping someone could advise on an air compressor that wasn't overly noisy. I've read the above threads and done a bit of a search, so I know I'm looking at an air compressor that isn't oil-less, and that a regulator and water trap are highly recommended (given Melbourne weather, I'll be getting a water trap).

Any suggestions as to what would be a good-value-for-money air compressor on the quieter end of the range?

Hi Mr Monk,

I bought something like this ebay item :  http://www.ebay.com.au/itm/1-6HP-Air-Compressor-for-Spray-Gun-Air-Brush-AS-186-/260985916715?pt=AU_Air_Tools&hash=item3cc3f90d2b&_uhb=1


I've only used it infrequently so far but has worked well & is very quiet.

Same type as I have, & works without a problem & as Alex says runs very quiet, good to have an air compressor nearby without a long air line to the large one shut behind the garden shed doors.

Interesting tool.

I see some pros/cons with this tool

Pros:
Good price
suitable air pressure range for airbrushing
comes with a water trap
quiet

Cons:
Maximum pressure is too low if you also want it for other air tools like a nail gun or braider.
The air tank is very small at three litres.

I have a 2.5HP/24 litre. This will run most air tools very well. I have used it extensively with a variety of tools like nail guns, staplers as well as my airbrush. That said, it is not suitable for a paint spray gun. Mainly because the air tank is too small. That said, when I am air brushing, the pressure is very low (about 20-30psi) and I can do a lot of painting before the compressor needs to pump/cycle the air tank. Consequently, I don't find noise to be a big issue.

The compressor in the link above would be quite adequate for air brushing though I suspect it may cycle frequently due to the small tank.

So in summary, if all you want to do is airbrush, then it would be fine, but it would be limited if you also wanted to use some air tools.

Good luck!

SA, if you take note of the whole of my post you will notice my comment regarding large one in garden shed.  I have a large compressor which I have used now for several years, has two outlets & one is set for air brushing & the other for full pressure.  In the past there has been several threads on RP regarding compressors for air brushing, & I have been very much a supporter of the larger types like I have, & I still am as they offer a fair bit of flexibility & certainly much of a jack of all trades & useful for a wide range of work & they do have the ability supply a very good & reliable supply of air.  Thus they have their part & worthy to be considered for the hobbyist.

The reason I purchased the small compressor was quite simple, & that was the large one was relatively inconvenient to use, it resides in a shed & pretty heavy & bulky if I want to move it to a location for work, I can handle that for the wider chores, but as I am also on a waiting list for back surgery not a good move to be trying to move it around.  Aside from that, I had been thinking of something smaller & more convenient to use in the train room, something that is cheap to run as against the large compressor, & more especially light & easy to move around & handy for easy quick use.


While the air tank is small, there are a lot of compressors out there, especially those sold by the model paint & air brush manufacturers that do not have an air tank at all, & they also can be found on Ebay & at the same shop as provided in the link, thus having one even with only a 3 litre tank is quite adequate for the air brushing work


I do not do a lot of air brushing & when I do its more often than not for small jobs & the smaller compressor actually makes air brushing a bit more of a pleasure than the noise, long extension cord & air hose connections that can mean extra prospects of water or moisture getting into the brush.  So, as this is purely for hobby work rather than for large air tools it fits the bill very nicely thanks.

A6et,

Apologies, my post has fell foul of an electronic glitch. My intended post was meant to have included all of your post, plus the post from Railmod with the link to the small compressor. While composing my post I had a brief internet drop out which seems to have dropped out most of my quote of you and Railmod which I haven't realised until reading your reply.

In summary, the point I wished to make is that the small compressor was/is fine for airbrushing but would be limited if the original poster wanted to use an aircompressor for other than air brushing.

I was not trying to make a point against you.

Hi Dan,

Like Col I also have a larger Bunnings type air compressor - has a 25ltr tank, but it is very noisy, but as you say it also does have other uses (I sprayed my kitchen doors with it & they came out quite OK & use it for my Pressure Pot when casting), the reason I mentioned the one I did is partially because the MeddlingMonk asked about a not too noisy compressor & the fact they also come with a watertrap, but point taken if the MeddlingMonk wants to do more then just airbrushing then they would probably not be too suitable.

Cheers Alex.

No worries at all, & there are certainly joys with computers & where a lot of what is written goes to.  Also the way the current reply mechanism of RP I think needs a lot more oiling or going back to how it was in the past as certainly its a right royal pain in the rear end trying to reply & even edit your own post/replies.

My first post was based on the aspect of the question asked by NSWrules who was after a compressor for weathering & other modelling paint jobs, thus the link to the compressor that Alex provided was appropriate for the task in question, rather than something of the larger types, mine being a GMC that Bunnings sold & they ended up killing the brand & company off eventually anyway.

Thanks for the replies so far. The intended use for the air compressor would be airbrushing (and maybe blowing the dust out of my PC occasionally, though that's not an essential criterion) - I'm not looking to do any heavy work with it, so the main concerns are noise levels (don't want to upset the neighbours) and quality. It doesn't have to include a water trap (i.e. I can get one separately), but would be convenient if it did.

railmod and a6et - that eBay one looks like it'd do the job. Would you mind mentioning how long you've had it for and what sort of maintenance, if any, it's required in that time? Thanks.

Dan  I have not had mine for all that long at all, & tried it out recently & it worked well, only problem was with the paint spotting which is more with the air brush rather than the compressor.  I gave it a good run with the air brush set to 25psi & when compressor stopped I had the air brush opened fully to see how the compressor coped with the air supply, while it cut in the pressure gauge did not drop, so I am taking it that its capable of maintaining the needed air flow.

Believe me it is very quiet, & as I have industrial deafness which is affected at various pitches I could barely hear it at first.  The other aspect that I liked with the compressor is that it comes with a stated 12 month warranty whereas many others have only 90days stated.

I also have a constant charge pump that is set to 30psi it is ok in a computer but barely, I have used the large compressor to give the innards a spray with it set at below 50psi & that was more than adequate, but I think its a bit much really.  So, I do not see any problems with this compressor doing that work either.

As its a small motor & air brushing can use a lot of air it did get a bit warm to touch when it was pumping constantly, but so did the big one.

I started with a 40L GMC unit with a separate water trap/regulator.  This worked well but was quite noisy and when I moved to my new place I couldn't bring it with me.

I then purchased a Runway13 AS186A compressor/tank for airbrushing and have been happy with it's performance so far (3+years).  My main criteria for purchasing was size and sound level, both smaller than the 40L GMC unit.  The ebay units linked above look similar but without the case and airbrush holders which I find very useful.  No maintenance required yet.

Over time I have noticed that so many items end up being almost so identical with the exception of the paint & brand on the product.  GMC when Bunnings took them over as their primary dealer, spawned another similar brand sold in Big W where I got the GMC from, likewise pretty well all the other market type stores such as Repco, Super Cheap Auto's & Bunnings new air compressor brand Trade Air all are pretty well the same compressor, & I wonder if they are not made in the very same Chinese factory, same thing as DVD players a few years ago were made in Maylasia with all having the same innards but a different case & brand.

I tend to think the same thing with these air brush compressors, especially when one does a check through all the ebay stores selling them, with basically identical items with little difference. Some have covers that sort of hide some parts, some have no tank etc, & some have the holders like the Runway model, some also include cheap air brushes as incentives.  

When I checked each of these out as well as the Runway model you linked to, the similarity is very much there except for the different style of the covers. Most notable in the look alike stacks is the pressure gauge/moisture trap arrangement which for all accounts Is identical to the $80.00 Ebay version which is a little cheaper than the Runway version. That said I hear a lot of good things about runway products overall. Overall though I could waste 3 of the cheap versions over 3 years all just outside of the warranty period & still have change in my pocket.

Hi Mr Monk,

I've had mine for about 1 & 1/2 years, used it a bit to spray a few models & showed/taught someone the basics of airbrushing & it worked well then, but it has not really had heavy usage. - I've not done any maintenance on the unit - BUT the pressure dial was broken when it arrived & the company concerned (Princess Trade?) replaced it very quickly no questions asked & did not ask to see, nor return the broken unit.

Cheers Alex.

Thanks railmod and a6et. I've found Princess Trade on eBay as well and they stock that particular air compressor, so I'll probably get one of those from them.

I think you would be right here as a Dremel like tool at Cheap as Chips here in SA a few years back was identical except for colour and brand to the Mitre Ten own brand there was a huge difference in  price though the Mitre Ten one you were simply paying more for their name on it. When it finally gave up the ghost a while back I handed it to a mate who had the Mitre Ten version of it and he used the old cheap one for spare parts, his now has one side of the actual body of it blue and the other side orange the cheap one was blue by the way, and the Mitre Ten one was orange.

I'm seeing more people (including MMRs who are not sponsored by Iwata Smile using Iwata Ninjas (http://www.amazon.com/Iwata-Medea-Studio-Series-Single-Compressor/dp/B002JLVM5U) at model shows.

They seem to work well and are very quiet although like everything else made by Iwata they cost a pretty penny.

When my Passche compressor gives up I'll be looking at one; I've not heard any complaints so far.

Actually, the longer the hose the less water in the air at the end, I work for an industrial compressor company and have been told by the engineers that the colder the air is the less moisture it will carry. A longer hose will let the air cool down a lot more therefore droping the moisture content in the air considerably. We also sell industrial air dryers which are basicaly just a large fridge, the hot air goes in one end and goes to about 2 degrees C where most of the moisture is removed.

Ok it's overkill for the hobbist but you get the point.

Fair enough, I admit to not having had much problems with moisture in the large compressor, however at our previous residence it sat in the garage & I worked in the separate building I used in part for the layout, it was around 15 metres away & it was still darn noisy for me, still works a treat though but I need ear muffs for it now.

While an overkill is true they do serve the multi task well but I really enjoy the quietness of the little on now.

This is overkill for hobby use.Laughing Imagine how long the small pump would have to run to fill this?
