I have an Ace grit blaster that I've had for years. It has a tee piece that comes out of the the front. I seem to spend about 5mins blasting and 4 times that unclogging the tee piece or refilling the thing. I'm thinking of giving up with it an getting an eBay 20 gallon. I'm I just going to get the same clogging? My compressor is a 2 x 3hp with a 280 litre tank.
