Ok guys, i figure im going to need to get a compressor sooner or later

can you guys please tell me what i need to look for

eg: what psi range, price, make, model.

i know i need a regulator and water trap but even so they can be baught seperatly.

just need some general advice, tips.

let me know what compressors you guys have, how you rate them and what would be ideal for me

and a point i would like to ephesise...i dont really want to be spending a great deal of money on one....deffinatly not more than £100

so if anyone can point out a decent one on ebay or know anyone who is selling one/seen one at a regular stall at a boot sale or something that would be great!

thanks.

This is what you want RJW,get you bid in,you should be able to get it reasonable as there are about 5 of these on at the moment.

thanks Barry, that looks and sounds great!

unfortunatly....no money untill next month, hopefully there will be some more up then!!!

***There will be more on e-bay,just place 'Diaphram Compressor' into the search box when you are ready for one,I think this chap is dealing in them,mine cost £150 all those years ago,and has no water trap or pressure gauge,so this is a really good buy,they are so quiet as well.

Good Grief!!, you can't go wrong at that price can you?

I'm sure mine cost somewhere in the region of 120.00 quid a couple of years ago. Still, I bought it from an art shop and they have always known how to charge!

rjwood_uk

yes it does seem like a very good buy, thanks alot for the point in the right direction.

I’m getiting back into scale modeling after a break of some years, and thinking I should finally get around to purchasing an airbrush and compressor after seeing the results that can be achieved.

I’ve narrowed down the airbrush choice but have a couple of questions regarding the choice of compressor and regulator / filter etc.

The compressor I’ve purchased is a Werther International



The manual states:

“Output is 70lpm free air delivered, maximum pressure is 50psi (3.5bar) but running pressure is less as an air bleed must be fitted to this machine and ultimate working pressure depends on size of nozzle assembly used. 150 watt shaded pole motor, thermally protected, on/off switch, for the occasional user (not continuously rated). “

I’m a little unsure of what is meant by an air bleed – it seems the regulator which can be used is one of two types, the regulator can either restrict the air to lower the psi or alternatively bleed some of the air to the atmosphere at the regulator and limit the air flowing to the compressor. The images below show the two types.



My question is – what is the difference in these types of diaphragm compressor available, all seem to be designed for airbrushing whilst some seem to mention this air bleed thing.

What experience do you have regarding these compressors? Any advice would be welcome. I already have the first type of regulator pictured above - would I damage the compressor if I fitted this type?

i have the one in the second picture, it came with my compressor from everthingairbrush.

i too have no idea what is ment by "bleeding" the air. but these two are not the compressors they pressure regulators and water traps. now i know on the 2nd one there is a little thing on the bottom you press to release the water that collecs and im guessing that is whats at the bottom of your one ( the silver bit ) so maybe it means bleeding the water not the air?

just an idea.

I had a look at the second type of regulator - it's described as a Bleed type regulator:

1/4" BSP Swivel nut air inlet to attach to compressor
1/8" BSP Male outlet to attach suitable airhose
100 PSI (7 BAR) Pressure gauge
50 micron filter to remove particulates and moisture from air supply
One-touch water drain
Bleed type regulator to reduce pressure

I assume it must vent air to stop some kind of back pressure building up against the diaphragm in the compressor or something. I just wondered why it seemed to mention this specifically with the Werther Compressor I purchased - maybe it's just a bit pony - might cause it to overheat or something if the airflow is restricted or something?

I also found this when I was looking for more info online, this compressor has internal bleeding - Can anyone help clarify what all this means? I'm sure it'd pretty much work by just screwing a regulator on the outlet but it's nice to understand why some things work and others work better:

CYCLONE I MODEL 180-1

not sure there sorry, i notice it says 1/8" BSP Male outlet to attach suitable airhose.

i didnt get that info with mine and had no idea what size it was going to be or what size the hose i got with my badger airbrush was so i now have to wait to get some adaptors. but now knowing that its 1/8" helps me alot thanks!!!

and i have lost my adaptor for use with "cans of air" so i cant do any spraying. my bradger is getting lonely.lol
