[BCMA] fans for positive pressure cases

[Moderated BCMA subscriber listserv.]

Hello all,

It has been many years since I built a positive-pressure case. We are  
about to go into production on Phase 2 of the Quatse Salmon  
Stewardship Centre and must protect a replica underwater sea-wall from  
dust.

Does anyone have current info on sources of small, silent, 24/7 fans  
and inlet air filters for the purpose? Or any other news on the  
technique would be most welcome.

Many thanks,
