Hello, you`ll have to find a way of keeping the compressor cooled; in a box it will soon get overheated and it will seize

I`ve got a broken one that proves that  


greetings, Bert

the search is as valuable as the finds...

Has anyone used a silent compressor with an airpen?  The free air from the smaller silent compressors is low (around 1cfm up to around 2cfm).  I am wondering if you can still get a useable pen in practice despite the low cfm.  Thanks

I tried a silent compressor with my tt pen as had a spare one, and it would not work. My normal compressor gives around 4.5 cfm. at 90psi,   5.5 cfm at 40 psi.

I don't think a tt pen would work with 1cfm airbus no knowledge of any other type pen

I have a silent one, works fine but is very pricey

A powerful silent one would work, but they are not intended to be run continuously, so it's not ideal for prepping. 

I have a fairly normal ƒâ€š‚£100 one which is super noisy, but it's quite easy to build a silencing box for it, if you have simple carpentry skills or if (like me) you hire a carpenter to build one.

Matt on here has one. Seems to cause nothing but trouble with the tt pen. And will overheat between 30-60 mins of orepping

Does anybody use the one Ken Mannion sells as part of his Complete Starter Setup offering?

I did have it, but it stopped working quite quickly. I'm not sure why, I think I was just unlucky.

I replaced it with a decent Machine Mart one with a bigger capacity, and have had no problems since.

Didn't Ken replace it???

Well, by the time I'd sent it back to him, it wouldn't have been worth it really. And besides, I felt that a bigger capacity would work better.

I bought the starter kit from KM over 10 years ago.... the compressor still works, but I replaced it with a bigger one a few years ago... I keep the small one as a back up just in case.

Can the starter kit compressor drive an air-pen?

Yes, it comes on quite a bit compared to the larger ones, but its more than capable of running an air pen, when using the air grinder its on almost constantly.

What capacity compressor do people recommend for ST and TT pens? Also any recommendations for brands to look out for or avoid?
 
Cheers,

Mr P.

If you go into Machine Mart, and get a decent 50 litre model from them, you can't go too far wrong. I bought a 50l and it never overheats and runs nicely.

Hi

I've got one of these:

Clarke Raider 15/500 3hp 50 Litre Air Compressor

It's 3 HP but runs off a normal 240V supply. It does 14.5 CFM, which is more than enough for airpens and all the air tools that I use.

I've also got a

Bambi BB24V Compressor - Silent Air


This is only 0.5 HP and does about 2 CFM

This silent compressor will run some air pens for a couple of hours before it gets too hot and trips out. It's no good for air tools such as grinders. You need a large silent compressor like Bow1980s if you are going to be doing a lot of work.

All air tools come with a CFM or l/min air usage. Your compressor needs to have an air generation capacity in excess of the air tool or alternatively a large reservoir for air storage.

If you are worried about the noise, go for a silent compressor (which are pricey) or build a sound suppression box.

If you are not worried about the noise, and you are just using air pens, then you can get a decent compressor that will meet most needs for less than ƒâ€š‚£100 or alternatively, go up to the next level with a bigger version for about ƒâ€š‚£200.

Thanks to you both, Aurelius and Welsh Wizard! My old compressor died when I started it up after a period of inactivity so the advice is very useful.
Cheers,

One other thing, are the connectors a standard fit? I have the ST, I guess this would just plug in ok?
Cheers,

Hi Mr P

Your ST pen should have a standard quick release snap connector.

Take it with you when buying the compressor and the sales staff should be able to tell you what you need. At Machine Mart, the couplings are only a couple of pounds.

My compressor is in another room and I have about 15 foot of flexible air hose that runs between rooms. When I bought my equipment, the only thing I had to change was the coupling on the compressor outlet.

By the way, if you go on Kens website, it gives you the air usage and operational pressures of the various pens.

Hi,
I use a Jun Air silent compressor for my CP pen. Works just fine. The compressor does get hot though....i can work for a about 15 minutes, then let the machine cool down for 15 minutes....etc...
It's a hassle but to be able to work without the loud noise is a joy !! greets, Marcel

Hi,
 
I'm using a Jun-air too! It's expensive but worth the money. It sounds like a refrigerator, wich is great. I also have a 'normal' compressor. This one I will install out of my shed in a rain and soundproof box. At least, that is the idea!
 
Greetings, Walter
