IIRC, the filter element is a standard folded paper element available from lawn mower suppliers. Google Media Blast Gloves
to find suppliers of replacement gloves.

Not exactly freight cars... but I noticed the other day that
both of the gloves in my North Coast booth are torn. Anyone know
a source for replacement gloves? And replacement air filters?
I have used one of North Coast's grit blasting cabinets for some fifteen years and swear by it. It is a Godsend when cleaning a brass model after changes have been made to it requiring soldering and is great for removing paint from most plastics without destroying detail. More recently I have found a wholesaler who handles them and have added them to the goods supplied by New England Rail Service. The working space is 11 1/2 x 18 x 22 so it is comfortable to work on models in. Aluminum oxide grit is available for them in 60, 120 and 220 size in 10 lb. pails for $20 to $22 per pail depending on grit size. By the time shipping is considered a cabinet and grit should be less than $200, which is considerably less than I paid for mine at the dealer cost from North Coast years ago.
