I am experiencing a real problem with my brush.
I got a brand-new Sparmax Sp-20x (0.2mm). For the first 1 - 2 hours it worked very well, although I am using a small mini diaphragm compressor (the ones you typically use for nail art, etc... yes, I know that I need a real compressor very soon!!!) which is pulsing at reducing rates, typically. I am using Golden High Flow acrylics, sometimes reduced with some water drops.
My big problem now: The airbrush appears to receive no air (or not enough air pressure) once I screw on the nozzle cap on top of the nozzle. If I run air through the brush without the nozzle cap on, it feels and looks like it receives plenty of pressure (it must be between 10 – 20 psi). If I screw on the nozzle cap, the pressure reduces audible to almost nothing. To avoid misunderstanding what I mean with the nozzle cap, I am attaching the breakdown of the brush, with the “nozzle cap” highlighted.
I checked and cleaned the nozzle cap continuously. I deep cleaned the whole entire rest of the brush. The problem persists, and makes painting virtually impossible… I don’t have any air power in that device that sucks and sprays the paint as it should.
What is going wrong here? Is it an issue if the small diaphragm compressor, and would a better compressor (at higher psi) solve the issue? Or do I need to be worried about the air valve?
Any thoughts and experience is highly appreciated. I may overlook something elemental. This forum has become my only sounding board for airbrushing issues… I don’t have other people that I can ask those questions, and I find you guys so communicative and willing to share that I already want to buy them a few cold beers
