 for Greenhouses. Designed and 

 Drawn by the American Green-

FISHER SPECIALTIES- 



THE BEST FOR EVERY PURPOSE 



Here is a typical layout of a 

 modern greenhouse vacuum 

 heating system, designed and 

 drawn by the American Green- 

 house Mfg. Co. of Chicago, 111. 



You can see there is a Fisher 

 device for every purpose — 



vacuum pump governors, air 

 traps, reducing valves, back 

 pressure valves, etc. 



Florists throughout the country 

 have given Fisher specialties the 

 time test of service and found 

 them entirely satisfactory.

FISHER SERVICE 



When contemplating new heating 



systems, or when replacing old reg- 

 ulating devices, consult our Service Department. 

 Oftentimes we can save you considerable money 

 in initial outlay and maintenance cost by specify- 

 ing time-tried devices especially adapted to your 

 particular need. 



Gravity systems work better with 

 FISHER steam traps. Thousands of 

 florists will tell you so. 



Our book "POWER PLANT SPECIALTIES" has 

 valuable information for florists. It's yours for 

 the asking.
