compressor for plasma cutting

[timgunn1962]

While it is still new, I'd check the size of the pastel in the Non-Return-Valve with a decent caliper and mark it on the receiver. You need to be able to measure to .1mm. If you wait until it fails,it mat have squidged a bit and measuring the old on will not necessarily get an accurate measurement. If yo fit a pastel that's fractionally too big, it can stick. It's worth getting a spare now, to save hassle in the future. It's also worth getting a spare inlet air filter element for the box-type inlet filter. I don't know whether that pump will accept Solberg-type inlet filters. If it will, they'll reduce inlet noise. Even the cheap Solberg-a-like ones work well. It's never a big difference, but it is often noticeable.

The best A/V mounts I have found for noise reduction are Paulstradyn. The movement on start-up can be a bit of a shock the first time you see it. Probably not worth it on a concrete floor, but we have compressors on wooden floors in shipping containers and it can make a lot of difference over "normal" rubber mounts.

And remember the receiver needs to slant downwards towards the drain end.

Good point, combined with a No-Loss Float Valve on the drain, you then pretty much forget condensate even exists.

Machine Mart have a belt driven 14cfm 50l on offer at the moment

I have an older one very similar. Absolutely brilliant. Same as the bigger garage ones just with a smaller tank. Keeps up easily with plasma and air tools etc. about the limit for a normal 13amp plug. Will run on an extension.

I picked up the new compressor today.
Looks the biz. Much quieter than the old thing. Old thing suddenly looks very sad.
My mechanic looked at it, stroked it and said aaaawww blessssss.
I did not have the right connector, that goes on tomorrow.
Thanks all for advice.

Belt drives are brilliant. I hate direct drives they are so noisy.
The Machine Mart ones are either British or Italian I think. Should last you many years!
