I had one like 35 years ago and worked perfectly on a MB 207 spending 1 year in Africa, it did save a lot of paper filters since the dust stayed in the pre filter.
see image then and my project now.
I am game.
Sorry Fellas. I came back from a ski trip to a flooded home. Frozen piped drenched my place for 5 days!!! Skiing was great. Now I am living in a hotel with my wife and 4 kids while we figure out long term arrangements. 3 months to put it back together.
Good New is: I'VE GOT MORE PRECLEANERS. THE BOXES ARE WATER DAMAGED BUT PRE-CLEANERS ARE NOT AFFECTEDE. :sombrero:
Still got plenty. Those of you who send the $$ by tomorrow by 10:00 Mountain time will have them in the mail USPS PP tomorrow by noon. Usual shipping is 6-9 days anywhere in the US.
You'll get brand new pre-cleaners in nicely water stained and warped boxes given the recent catastrophe which occured in my home over new years. :sombrero:
If you are interested then sent $35 to my paypal address: danrohweder@yahoo.com. PM with you address to be sure I have the accurate addy for mailing.
