This unique hand spray blow-off gun features an adjustable spray pattern and a calibrated lube flow adjustment knob. The patented atomizing system reduces air consumption and produces non- turbulent spray patterns extending up to 6 feet from the nozzles. A separate air-blast nozzle is used for maximum blow-off force. A wide variety of interchangeable nozzles are available. All nozzle components also interchange on Shamrock's Automatic Spray Heads used on reciprocating or stationary spray systems. All seals are standard 0-rings. The extra-long operating lever reduces fatigue and increases control of the spray action.
UNIQUE DESIGN FEATURES:
The Shamrock Hand Spray / Blow-off Gun uses innovative design and construction to overcome the most frequent complaints regarding other brands. Shamrock's unique atomizing system (U.S. Patent No. 3,907,207) directs pressurized lube radially from the center of the nozzle mixing chamber into a thin curtain of high-velocity air. This system produces a fine mist, even at high fluid flow rates, with a minimum compressed air requirement.
Interchangeable nozzles permit matching the spray pattern to the job. The No. 2 nozzle, producing a small fan spray pattern, is used on most dies. The No. 0 nozzle produces a narrow cone spray pattern and is used on dies having deep ribs and cores. The No. 4 nozzle which produces a medium fan spray pattern, is used on shallow contoured dies to minimize the spray cycle time. All nozzles are fully interchangeable between the Hand Spray Gun and Shamrock's Automatic Spray Heads.
A separate, vented air blast nozzle is used to provide maximum blow-off force with minimum air usage. Maximum operating noise level is within OSHA limits with an inlet air pressure of 90 psi.
RELIABLE OPERATION:
The extra long control lever minimizes actuation effort and reduces operator fatigue. Pressing the control lever down slightly produces a strong air blast from the blow-off nozzle. Depressing the control lever further stops the air blast and starts the atomized lube spray. The unique, non-turbulent spray pattern extends from 3 to 6 feet from the gun tip (depending on nozzle style) providing controlled lube coverage in deep cavities and on remote areas of large dies. The patented Shamrock atomizing system is much more efficient than other brands, requiring up to 60% less compressed air volume for the same amount of effective lube transfer.
The large calibrated lube flow adjustment knob is easily gripped even while wearing gloves. Less than one full turn is required from minimum to full on, allowing lube flow to be increased quickly during the spray cycle to cool hot spots and then reduced to spray the rest of the die surface. This can reduce total spraying time and lube usage while improving casting quality. A positive mechanical stop prevents the knob from being removed accidentally.
The actuating valves are located under the control lever for added protection. The hand grip position adjusts easily to fit any hand size. No special seals are required as standard 0-rings are used throughout. The adjustable hanger and integral brass flash scraper are convenient finishing touches.
