high pressure steam systems, condensation is one 

 of the most formidable obstacles to economical 

 operation. It ceases to be a problem if the 

 Fisher Steam Trap, No, 33, is used. The 

 Fisher automatically, quickly and positively eliminates all 

 condensate, without wastage of steam. The capacity is 

 so great that if desirable one trap may satisfactorily 



serve where two would ordinarily be 

 required. 



Positive control of temperature is as- 

 sured by Fisher Reducing Valves. 



On either high or [low pressure systems 

 they convert any initial pressure to any 

 desired lower pressure and maintain it 

 evenly. There can be no dangerous 

 fluctuation of temperature with a 

 Fisher Reducmg Valve guarding the 

 pressure. 



For vacuum heating systems, Fisher Vacuum 

 Pump Governor, No, 8, maintains a steady 

 vacuum, the range of which depends upon the set- 

 ting of the weight on lever. We are able to build 

 this governor with angle as well as globe bodies. 

 You will readily appreciate what convenience and 

 economy of space this unique feature means. 



You need never have air accumulations or pockets 

 in your hot water mains. The Fisher Auto- 

 matic Air Trap, No. 30, instantly and auto- 

 matically releases air, while sealing tight against 

 the water. It has great capacity, and if placed at 

 the highest point freely relieves the entire system. 



Fisher Greenhouse Economizers make a vital appeal to the greenhouse operator 

 — they are money savers. That is also true of many other Fisher devices 

 besides those shown. 



May we send you more information about Fisher Greenhouse 

 Economizers? A letter or card will bring it.
