A FNG question, a friend of mine has this old blower, no markings on it that i can find, looks similar to a SCOT unit but has some differences (Judson maybe?). does anyone know what make this blower is? does it have any value? does anyone have dimension for a SCOT blower for me to compare it to? Any help would be appreciated. Thanks
Doesn't appear to be a SCoT and does look rather large to be a Judson (although I understand they came in different sizes). Looks very mil-industrial - perhaps aviation related?
Don't know what it is, but that looks great.. I can think up several projects that would be a great addition to. So yes, it has some value, just because it's a little different.
I've no idea what it is, but I believe a number of European marques made their own blowers in earlier years. One thing to look at that may give some idea of where in the world it came from is whether the fasteners are imperial or metric.
Budd, you da man! These have been used for years for blowing things thru ducts and piping, etc........fibergl*** in mills, wood chips, or as a vac*** source for ****ing things thru ducts and pipes.........
Budd and Screamin' metal can you explain further? as in a shop air compressor for running pneumatic tools?
Not to argue, but I'm wondering if it is a Schwietzer supercharger from an early ***mins diesel. I know from pictures that they had multiple fins such as this one. In addition, I believe the superchargers were gear driven.
does anyone have a picture of this "Schwietzer supercharger" a quick Google search didn't show me much but i'll keep digging
I misspelled it, I believe it should be Schwitzer. I have seen pictures on the 'net just can't remember where!!, and an early blown ***mins powering a 1951 Mack in person, but I don't remember enough to positively id your unit.
heres kind of a ****y pic of the ***mins diesel with a blower, it does look much the same but doesnt have the same front end, and on an engine you would think they would use crankcase oil and not grease fittings.
Dosn't help ID the unit... but the guy is certainly interesting. google#1 Schwitzer edit for link http://www.cruise-in.com/resource/cismar03.htm
I may be wrong about the gear drive, it has been awhile since I saw the blown ***mins in person. A far as the crankcase oil, that's a tough call. I think compressors on diesel engines have their own oil supply, but use engine coolant instead of fins like a shop compressor. I st@ 2b corrected.
I believe what you have there is a supercharger from a legendary ***mins NHRS "Iron Lung" engine. These engines came in trucks from the early 50's into the late 60's. Some made their way into industrial applications as recently as the 1970's. The NHRS used a disc-style fuel pump which was the predecessor to the PT pump introduced on the NH series engines. The combination of the disc fuel pump and the supercharger made the engine whine like a banshee at full load. In the middle of the night you could pick out the sound of the ***mins "Iron Lung" from other trucks running in a pack... kinda like having a top fuel dragster in the middle of a bunch of Honda's. Here's the sound of an 275 HP NHRS Iron Lung at high idle in a Bull nose Kenworth. http://www.youtube.com/watch?v=WZDxj8E7acI&feature=channel_page
Krooser is right also, and they were also used as blowing and suction devices on heavy industrial applications. There's a really large machine behind a bearing facility right outside of Birmingham, Al. and this machine has about 3 or 4 of these blowers on it, being turned by a 200 HP electric motor. See the large bearing housing on the one end??????
I remember seeing roots blowers in 1950's war surplus ads in Pop Mechanics type magazines...they were apparently used to pressurize cabins of airplanes, which would probably mean B-29, Constellation, maybe DC 4 types...not very many WWII panes were pressurized. The ads gave no clue as to size or capacity.
http://victorylibrary.com/supercharger/super-pics7.htm have look around on here, surf around this site has loads of info
The blower looks a bit like an English Wade unit although I dont think it is. The Wade has an angled outlet . See the link below. http://www.bcsc.co.uk/info/supercharging.html Also, that Judson supercharger depicted on the You-tube clip appears to be a vane type. Can someone confirm that?
its looks like the large Marshall superchargers on these websites, does anyone have more info about these units??
http://www.flickr.com/photos/80652380@N00/391355007/ Did you try to google marshall supercharger, lots a stuff to read an find, this looks like yours mounted in front of the radiator crank driven, *****en! Also try marshall cabin blower , used for light air craft also, retrofitted on british sports cars, that victory site has a lot of info and links
This link shows a schematic of a Marshall blower and looks like the one depicted http://www.flightglobal.com/pdfarchive/view/1945/1945 - 1178.html Cabin blowers have been used to good effect as superchargers. Below is a pic of a supercharged VW powered hillclimb special which utilised a Rootes type Godfrey Cabin blower. This pic was taken easter 1971.
