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?
