"■FISHER VACUUM GOVERNORS 



The governors are installed on their vacuum pumps. They consistently 

 maintain any amount of vacuum required. They have successfully done 

 so for several years. The performance of other Fisher Governors assures 

 the long life and lasting satisfaction of this governor. 



Fisher Pump Governors are not new. They have been. on the market 

 for over thirty years. Many of the "old timers" are in service today — 

 proving the durability of Fisher Governors. 



Perfect reduction from high to a uniform low pressure is 

 obtained in the Amling range by Fisher Reducing Valves. 

 These valves are dependable and through years of service have 

 added to the reputation established by Fisher Governors. 



Inner valve construction is double-seated and is made of our 

 special formula, hard phosphor bronze. It will not stick or 

 wiredraw. 



Our interesting book, "Potver Plant Specialties," tells 

 you all about Fisher Governors, reducing valves and other 

 greenhouse fuel economizers. It's yours for the asking—
