INTRODUCTION 

The Model AA27H-- GunJet® Spray Gun is a high-pressure spray gun which 

features a heat resistant aluminum alloy handle that remains comfortable even 

while spraying high temperature liquids. The comfortable trigger grip remains 

responsive and easy to operate even at maximum flow and capacity conditions. 

As a safety feature, a Trigger Guard and special Safety Lock, which locks the 

trigger in the “off” position, help to prevent accidental discharges. The Model

for both the inlet and the outlet connections, within the accessories pressure
