This is the battery powered respirator.
As far as I know it was made by a company called TRITON for the British/Australian/NZ market and is no longer available.
The respirator filter uses two standard P2 cartridges.
It's a bit clunky and underpowered compared to more recent respirators but given it includes a helmet/filter/face shield and muffs it has some uses.
The Muffs are so-so (only 25db reduction) so had to use additional ear plugs when milling.
I also found it was underpowered in terms of air delivery so I replaced the dry cell batteries with a higher V Li-ion battery pack but this still did not provide enough air in hot weather to remove sweat generated when milling.
Have used it only a few times when milling on super dry logs in confined spaces.
However it does have many other uses including to destroy wasp nests and cleaning up very dusty environments like my deceased Father in law's shop which was ankle deep in sawdust.
In my shop I have very good fully plumbed dust extraction with a 4HP extractor located outside my shop
