Compressor and blasting.

Hi,
Not put much on here for a wee while as I've been busy outdoors with laying lock block, installing roller doors,harling (pebble dashing to you doon Sooth!)'pointing and generally working away doing some jobs on my good lady's "to do" list, and quite a few that hadn't made it on to it yet!
Anyway, I would really appreciate some advice from "them as wot know and do"!
Some time ago I purchased an MSB soda blaster/ grit blaster. I've seen umpteen videos of these and other similar pots in use and results seem impressive. However, when I do it the damned thing keeps clogging and I spend more time unclogging it than I do blasting, and last year I gave up.
I keep the soda/grit in the workshop which is pretty dry,so I assume that the water removal from the compressed air is well below par. Can someone please tell me some proven gadgets to put inline to keep my air dry. Names, models, suppliers all would be welcomed.
Thanks in anticipation.

First -make sure the compressor receiver is well drained. I would also dry the soda on trays in the oven (when SWMBO is off site.... ). then keep it in sealed containers You could pass the air through a vessel containing silica gel - but it would need to be able to take the pressure - and/or, put a silica gel container on the intake to the compressor to dry the air on the way in.

I knew I could rely on you, Roy. Thanks. Like the idea of the silica on the way in!
However, any other suggestions re good quality water traps etc are still invited. Belt and braces, glue and screw etc!!
Thanks again

Oh yes - you can get self draining water traps to put on the compressor outlet - but they only remove any 'free' water and don't really 'dry' the air. Here you go... http://www.ebay.co.uk/itm/AIR-REGULATOR ... 2590e35487

I have a very good quality Norgren Olympian water filter/pressure regulator installed in the delivery side of my compressor and whilst it is good I always find that it is better to wait for a day with low humidity if doing something that could be effected by the moisture content. And yes I still have to drain it on a regular basis.
My local Aldi recently had on special offer (at nearly half price) a WORKZONE Air Filter Regulator & Lubricator with hoses and couplings Model No: WWAFRL/13,03/2013, 49865. I purchased one and it has yet to be installed so cannot comment on the quality of the product. They do come round on offer at Aldi quite often. :D
