Respirators

[SlipStream77]

I've been researching buying a new respirator for when I'm airbrushing. I usually use acrylics but I'd like protection to cover spraying primers and solvent based paints as well.

I spray in a very small room but with a window wide open, I was wondering if anyone can provide me with some advice on which respirator would be the most suitable.

I was advised that this 3M mask would be suitable but it's semi disposable, I'd rather be able to change filters.

I'm looking at one of these, would it provide the same level of protection?

3M are very good, but make sure you get the correct filters for the stuff you are spraying.

http://www.little-cars.co.uk/ sell masks and will be able to offer good advice.

I got a Sundstrom SR90-2 M/L mask with a Sundstrom cartridge Gas Filter SR297 (ABEK 1), both from ARCO. I keep the filter in a sealed sandwich box when I'm not using it since they degrade if not stored in a small airtight container.

I also use a spray booth with extractor.

No idea if they do any good, but I'm not dead yet.

Also make sure you are clean shaven as stubble will make a poor seal with the sides of the mask. I've got a 3m one with replaceable cartridges, works well but as above make sure you get the right ones.

Added to which, a dirty great extractor works a treat as well. I think I can change all the air in my workshop in under 2 minutes. Works well as air-con in the hot weather as well!

I built a mini spray booth. Cheap cooker hood in the back of a large cardboard box, flexible tumble drier hose hanging out of the window.

Thanks for all the advice, I've sent an email to Arco to see if they can advise too.

I will put some thought into a makeshift spray booth as well, sounds like a good idea.

Then I will finally be able to get back to modelling again!

FWIW just buy a sparaybooth. If you do go down the DIY route, consider explosion proof motors...

If you're after something easily storable, these are very good;

but yes, as dr_gn says, if you build your own, be very careful on which motor you select.

Thanks, that's good advice, I hadn't considered the risk associated with motors and flammable vapour - duly noted.

If I go down the route of a spray booth in addition to the respirator, I will certainly look at pre-made ones.
