sandblasting hood

Frank Caldwell · Feb 28, 2012

When I am sandblasting, my lense fogs up on my hood. Anyone have a recomendation for a vented hood?

My reply is on the paint and bodywork forum.

30 years ago I worked in a big blasting booth. The hood I wore had compressed air plumbed to it.

Don't really know (that's never stopped me before) but many years ago in scuba dive class, I was taught that regular compressed air out of a regular air compressor had tiny drolets of oil, and caused some sort of bad lung disease. Compressed air for humans comes from a special type of compressor.

A minimum 1/2hp (3/4" is better) Gast or Thomas vane compressor or vacuum pump will supply an air fed helmet. They can be had cheap on eBay.

Alot more expensive is a good helmet. I used to run enough air into my helmet so that it nearly floated off my head. There was no chance of a foggy interior or dust migration into the helmet. It probably consumed more than 25 CFM. I was a professional SB contractor using the entire output of a 750 CFM screw compressor for one operator.

Don't skimp on good lung and ear protection.

You know, I never thought of this till now - even though I constantly battle the same problem (blast everything with my head tilted up to one side looking out that last little clear 1/4")

When we go scuba diving we spit in our masks and wipe it around on the lens to keep them from fogging... I never considered how or why that might work, or if there's a less nasty alternative....

- but - might be worth trying? Or at least worth googling for an alternative.

Google "cat crap anti-fog". It"s like 7 bucks. Works good. I used it in the military. Shawn
