Hi list,
Over here in the Uk theres a portable filter set available for under £200.
This has a di inlet, filter cartridge with user replaceable cartridges, one
way valve and din outlet. A very neat unit but again it is restricted to to
6CFM throughput
I saw this unit this week when a friend of mine brought it for a cave trip
to france where the air is known not to be double filtered.
I dont know the make and supplier details but will find out and post to the
list later

David
