57 bcr Posted October 11, 2012 Share Posted October 11, 2012 That filter is a Farr Dynacell Dry-Type air filter.They were an alternative to the old oil-bath used on many engines at the time (late 60's-early 70's).By time the mid 70's rolled around,MACK & others had switched to a dry element in the round housing like the oil baths used.I believe they were less restrictive than the oil bath also.I still see them around from time to time,mostly at antique truck shows.

kscarbel Posted October 11, 2012 Share Posted October 11, 2012 Farr air cleaners were popular with west coast customers.Farr was sold to a Swedish company (Camfil AB) in 2000. Then Camfil sold the Farr division to Parker Hannifin in 2002, and it became Parker Farr Filtration.http://www.parker.com/literature/Hydraulic%20Filter/Farr%20Literature/Parker%20Farr%20Brochure.pdf Quote Link to comment https://www.bigmacktrucks.com/topic/27754-square-air-filter-boxes/#findComment-141235 Share on other sites More sharing options...

Vladislav Posted October 12, 2012 Share Posted October 12, 2012 Steve, by the way, when I wrote you I always wanted to wright "Steve" but I noted "Stev" in a place of your name.Please clean this conclusion for not making conclusion by me or maybe anybody else calling you a wrong name.On my mind round filters look better on a rounded corner R's as they are.Vlad Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/27754-square-air-filter-boxes/#findComment-141385 Share on other sites More sharing options...

57 bcr Posted October 14, 2012 Share Posted October 14, 2012 We have a a Farr/Camfil palnt in nearby Crystal Lake,Ill. When it was built in the '50's it was the P&H Diesel engine plant.Just a little useless trivia for BMT users!
