Cheaper Heat 

 For Greenhouses 



You florists who use the hot water system of heating Icnow 

 how air in a pipe line retards the free flow of water. 



And you know that air in the pipe lines is the usual cause of uneven 

 temperature throughout the houses. 



In order to overcome this opposition to proper radiation you generate 

 more heat and, consequentiy, burn more coal. 



But you can avoid this needless waste and insure even heating by using a 



Fisher Automatic Air Trap 



(TYPE 30)

^m A Fisher Air Trap installed at the highest point in your pipe lines will 



^H relieve freely all air and close tight against the hot water— guaran- 



^H teeing even heat throughout your houses. 



^1 It is a simple device— self-contained— has no outside adjustments that 



^= can be tampered with. 



^B Its short, powerful fulcrum insures positive action. 



^B Fisher standard of construction is adhered to throughout. 



^E Forty years of hard, everyday service have proved the superiority of 



^= Fisher Specialties. Fisher Air Traps are worthy of the name they bear.
