History of PD Blowers

Meyer and Sons, one would note the sameness of their design and dimensions to the Sutorbilt airlock as theirs was placed on the market shortly after the versions at Sutorbilt were discontinued.)

By the early 50’s, the Sutorbilt unit tools were getting tired. Impeller contours were still ground personally to matching sets. There were 3 to 5 persons who did nothing fabricate impellers. By now Mr. Clark owned the large majority of the business as Bill Sutor had left this company in 1946.

The blower industry was never at a loss for new applications. In the late forties an inventor came into town from Minnesota. He had invented an Isomagic ice machine that he could sell to each and every restaurant. Imagine, ice cubes at your demand, pure and crystal clear. The clear part was the important word. Everyone knows that each commercial icehouse uses an aerator to bubble the air through the ice as it freezes to insure clarity. Lots of PD blowers were bought for this purpose. This Minnesota inventor had a patent in the process and needed a lightweight blower to solve his aeration problems. Since the pressures were light an alternative series blower with aluminum parts and a 2-½ inch gear size was designed and created. Some 250 unusable model 2520 aluminum blowers began to gather dust on the shelves as the venture failed. Since the aluminum elements limit severely the pressures at which a blower can use, there they sat, a monument to the Isomagic company.

The Uranium Trend

The Cold War came to the rescue. The search for Uranium drove a craze, not heard of since 49ers poured across California searching for gold. The deserts of California, Arizona, Nevada and Utah crawled with uranium searchers looking for that elusive element that until a long time ago was described inside the dictionary as a “pointless” metal, not found inside the United States of America Geiger counters were at the ready as a mass movement not seen since the gold rush era of the unemployed of the Great Depression made its way along the deserts. Once a find was made, the claim may be staked and then “proved.” The proving was the challenging part. A core sample would have to be taken and given to the assayer. How to discover the core sample was the problem. The typical core sampling was completed a wet method. There seemed to be no water on the desert and for that reason the need for some sort of dry recovery method.

Enter the scene a gentleman in the remote Simi Valley. Reese Houston had been his name although people promptly rechristened him Sam (The name Sam stuck until finally he changed it legally.) Sam had an idea. A two man pack operation that will carry the core driller and the core remover. All powered by a chain saw engine. Not a bad idea. He had the core driller doing work well. All that was left was a small lightweight vacuum to pull out the cuttings. Compact struck a chord. Why don’t you try the Isomagic blower that only weighed 12 lbs. After all there was not a way he could use up 250 blowers. He was magnanimously loaned a test machine and off he proceeded to go. blower packages
