Small Hyundai compressor suitability for air fed mask?

[julianf]

Do you recon one of these would survive running an air fed mask full duty?

Currently I have a 3hp fiac direct drive running the air fed. It sucks loads of power, runs almost full duty (I have the regulator set to 6bar for the mask and it still runs almost full duty) and makes a right racket.

I forget how many CFM air fed systems need?

This is only running the mask, not the gun.

The honeywell/sperian airvisor II requires approx 10cfm. Devilbiss quote less even though they are both the same unit. I’m not sure on the requirement for others

I had the Honeywell mask. My 3hp compressor was on full duty to power it. Then there was the cost of the carbon filters in the three stage, which expire and are costly as heck. I gave up.

I never really see why a lphv fan wouldn't be better for air fed.

I mean, my Henry, if it were able to reverse, would blow way more air than I could suffer, at a fraction of the power use, and without any oil at all.

I have to use two compressors anyway, so it's not like I "already have the compressor"

What do you use now? Also fed up with the Honeywell.

Problem with lphv would be if your power drops out you no supply of air residual.

Hplv you can atleast exit the booth before you are out of air.

I use a full face 3M carbon filter mask. There's a PDF floating around this forum from a European health and safety department that tested carbon filters and found they filter out the isocyanate very well. I also found old memos from our health and safety department saying that they won't approve a passive mask because of risk of leaks. Well if risk of leaks is the risk then I'm happy to take it. I also think that compressor fed masks have their own risks which I'm not happy about.

Be sure to read the pdf though once you've found it as it says the filters need to be regularly replaced.

I have just bought the Iwata 2020 helmet. I'm quite impressed with it, the only niggles being that it is tight when wearing glasses And the fabric hood for the back is utter rubbish, held with three tiny bits of Velcro, which don't. I was pretty amazed that the visor film didn't get covered in overspray, yet my old 3M did. I could probably use the same Iwata film for a few sessions.

As far as carbon filters go, I have never changed one and it is only recently that I have noticed oily smells in the visor. I had new filters on order for months that never came, which is why I bought the new one.

Seems like a very silly choice to put an Acetate visor on a spay painting mask.

But you are meant to use a disposable film on top of the visor.

Is that compressor really 5.6cfm? I think it is really 2.2cfm. What service will it sustain - continuous rating or intermittent? As others have indicated, you don’t need 6 Bar for a mask. Carbon’s reply is correct it would mean that compressor is way too small.

3kW compressors generally deliver somewhere around 10cfm - whatever the marketing hype might try to make you otherwise believe.

Not paying the ridiculous prices on those

I’ve just had a quick look on eBay and the first one I’ve found is £13.95 for a pack of 10 covers. So just under £1.40 for a disposable cover
