Subject: Portable filters for compressors
Thanks for all the people who replied to me, I appreciate it. For those who 
mailed me and asked for any information I got on the subject here it is.

<<I collected such a filter a week ago from MDE at Leicester so
that I could brew nitrox using my portable compressor.
Talk to:
Terry King
MDE Ltd.
57 Sparkenhoe Street
Leicester
Tel. 0116 2624262

Total cost was -281.99 inc VAT and the system comprised: 232bar
female DIN, filter tower and filter element, hose, one way valve,
purge and 232bar DIN male (all components downstream of the one
way valve are O2 cleaned and 'compatable').

NOTE. The idea of using this to brew nitrox using an unknown oil
lubed compressor is a bit dodgy - the compressor should use
synthetic, not mineral, oil and, of course, its primary filter
should be in good order.  It certainly won't do any harm to
straight air though.<<<<<<<<<<

They do Cylinder valves, Hoses, Filter Towers etc - all are made in store and
is of Excellent Quality they have been involved in diving for years and apart
from the std bits they do they will do custom anythings ie gas switch blocks,
Decanting Hoses etc.  I called them just before I went to Scapa earlier this
years re a portable filter tower, they do them as std parts, in both DIN and A
clamp.  We didn't get one in the end as I called the skipper and his compressor
is triple filtered.

Call them and talk thru your requirement - they are divers and are technical
too so will understand what you need>>>>>>>>>>>>>>>>>>>>>>

So, to summarise, yes they do exist and are not that expensive. They will 
improve the air quality coming from the compressors but you will still need 
to check on the compressor to find out if it is incompatible with filing 
cylinders that have high ppO2 in them already or in the futur.
