" HOLDER " PNEUMATIC SPRAYERS 



are unsurpassed for 



SIMPLICITY 



Self-contained pump (no outside pump— to get lost— or 

 loose parts of any description). 1 minute suffices to 

 pump to the requisite pressure to discharge the whole 

 of the contents in a fine mist-like spray without residue 

 and without re-pumping. Ail parts easily 

 accessible. 



POWER 



Average working pressure, 70-80 lbs. The Spray is 

 steady and constant, and very different from 

 that produced by the old type of fatiguing "arm-work" 

 machine. 



Both liands being free for the lance, standards can 

 be sprayed with accuracy and economy of fluid. 



RELIABILITY 



Barrel riveted throughout — like a boiler. In welded 

 copper or brass, many of the machines standing over 

 300 lbs. pressure. Pressure - gauge auto- 

 matically registers pressure. 



" Holder Sprayers" passed through their experi- 

 mental stages years ago, and are not to be compared 

 With ex fieri mental pneumatic machines, mniie of 

 iron sheeting, and -ivitli frequently not even a 

 pressure gauge fitted. 



Made in 10 sizes, from 12s. 6d. to £5 12s. 6d.
