Attaching a tank to a small diaphragm air brush compressor

by Mike
(Stevensville, MD USA)

I currently own a small 1/5 hp diaphragm type, tank-less air brush compressor. It works ok, but I really want the smooth supply of a tank. I just ordered a 2.5 gal tank with 7 female 1/4" npt ports in hopes of using it as a storage tank. It is designed for use with air horns, but I thought it might work for my purpose. What do you think? Will it work ok? How would I go about hooking it up? Thanks a a lot!, Mike

Air Brush Tank

It should work great.

Hook the compressor to one end and output to the other.

I suggest a ball valve on tank in and out line to lock off pressure between jobs, as compressor will now have to fill tank.

A low pressure regulator on output line set lower than compressor output but works good on the spray unit would help as well.

Some states require safety blow offs (PRV's) on tanks.

Attaching a tank.
by: Bill - Publisher

Hi Mike....

That's the problem with the low cost diaphragm type air brush compressors. They provide a pulsed air supply which is a problem in that the paint flow will change with pressure fluctuation.

Diaphragm compressors are also deliverers of fairly low pressure as compared to their higher cost, and noisier, piston type cousins.

Adding a reservoir will help remove pressure pulsations from your air supply, provided your regulator is set below the pressure set points of the compressor.

I can't see any reason why adding a tank to your compressor will do anything but help your air brush painting.

Make sure that when the compressor is running to fill the tank, that it doesn't exceed it's duty cycle.

Just run an air line from the compressor discharge into the tank's supply receptacle.

I'd put a check valve into the line from your compressor to the tank so that higher pressure in the tank can't get back to the compressor as it starts and stops.

Is your unit an auto start, or do you use a foot switch? If you use a switch, how will you control the compressor on/off cycle to fill the tank?

A picture of your tank would be useful to help understand what connecting equipment it came with. Here's a link to a page with information about someone that has done what you're thinking of doing.

In this example, the tank is detachable from the air source. Nevertheless, it is a remote tank filled from a compressor, and used to supply air to a number of different devices.

Regards,

Bill

Can't turn regulator knob on brand new Windstorm by Sparmax

Windstorm Regulator

Windstorm Regulator

I am new to using compressors and have a brand new Windstorm compressor. I have followed the instructions on adjusting the regulator, but I'm simply unable to get it to move. The top of the knob says "push lock" and shows a double-headed arrow to adjust clockwise or counter-clockwise. I've read the instructions carefully and #5 just says to adjust regulator only when power is on and airbrush is connected. I have followed the instructions. Is this knob just stiff from being new? Needs WD-40? I don't want to use a wrench if it is going to damage something. Thanks in advance: Brad

Hey Brad. As per your note "The top of the knob says "push lock"", the adjusting knob on this combination filter / regulator is a locking one. You need either to pull it up or push it down to lock and/or unlock it, I suspect.

Rather than just turn it with brute force, try pulling up on the knob.

Let us know if this does anything, as a comment here, will you?

Cheers,

Bill

no air out of air hose through valve on airbrush compressor

by Arthur



i have air coming from my compressor when hose is attached, but when i connect hose to valve body no air comes through, this is even before i connect to airbrush

Art, I reposted this to get the photos to appear.

On photo 1, air is coming from your compressor when the hose is attached, and out the end of the hose. Is that not a coupler I see in the photo? Is it not checked? That means that air will not flow when there is no connector inserted into the coupler.

Now, in photo 2, you have inserted a valve or something into the coupler on the end of the hose. The picture is a bit out of focus so I can't quite see what that is.

However, if air is coming out of the hose when you don't have the valve inserted, and then you insert the valve and the air flow stops, then your valve is has to be the problem.

Air Brush connection won't?

by Jim
(Buford, GA)

I bought a Powermate VP201 compressor at a garage sale to use for my airbrush. I am trying to determine how to connect my Paasche air brush hose to the compressor since none of the connectors seem to fit.

Thanks,

Jim

Hi Jim...

You have a couple of options, but the simplest would be to remove the discharge coupler from the discharge line of the air compressor, and replace it with the Paasche connector, which has a unique footprint for their products.

If you do a search for Paasche quick connects, or connectors as I just did, you will find a host of sources.

Cheers,

Bill

Airbrush connection
by: Ronald Norris

I have been fooling around with airbrushing for about 1 1/2 years. I don't know how long that you have been doing this but here is a site to go to. They will answer any question that you have about this type of stuff and just about anything else on this subject. CHICAGO AIR BRUSH SUPPLY.COM, also THE AIRBRUSH FORUM.COM. Best of luck
