Here is where Filtex started. (See image.) The company was founded by a woman and the original location was here in Los Angeles. I have a write-up around here somewhere from a 1940s issue of the Los Angeles Times that tells about her - the tone of the article is "marveling" at the fact that a WOMAN is actually the founder and CEO of a large corporation!
A woman used to own and operate Buhl-Tornado industries-the one that now makes one of the only two external filter wet-dry vacuums.The Filtex Central cansiter units look just like one I saw in the garage of a home while looking at their yard sale-the vacuum wasn't included-asked them about it-they really liked the system.What sort of dirt collection does it use-do you dump the canister or does it have a bag?noted what looks like two external motor units on the one pictured here-at that house it had only one.Sounds like an interesting vacuum.Now Tornado industries is part of the Tacony group.
Had a female managing director at one place I had to put up with at one time, very formidable woman..fearsome, got the job done and didn't care if you didn't like it.
That would be nice-the paper bag in the cloth one-would make it easier at emptying time.And the dirt is filtered out of the airstream before reaching the suction motors.Looks like the motors are in series-one has a sealed fancase-the other one the fancase is vented.Would figure the vented fancase motor is the last one in the suction circuit.
They had two motor models with the option of parallel or series. One model with the motors piped in series had a high water lift and the parallel had a high cfm.
Oh, I see - I didn't realize they had two motors mounted on the sides like that. These are completely new to me, central vacs are quite rare around here for some reason and I've never seen a Filtex cleaner except the canister model at Fred's.
