SELECTING THE PROPER SAFETY AIR GUN
Distance – Close-in or far-away application?For maximum efficiency choose a safety air gun with a short or no extension for close-in work. Use an extended reach safety air gun for cleaning far-away surfaces.
Air Supply – Size of compressed air line?Match the airline at the workstation with the safety air gun. Small diam-eter air lines (1⁄4” to 3⁄8” ID) power low-thrust models; larger diameter air lines (1⁄2” to 3⁄4” ID) power high-thrust models.
Ergonomics – “Thumbswitch” or “pistol-grip”style handle?Thumbswitch style safety air guns are often preferred for applications with overhead air line feeds. Pistol grip style safety air guns are generally pre-ferred for air lines fed from below. Operator preference, including comfort and grip, is key.
Additional Safety Features – Additional operator protection required?Choose a safety gun with blind-hole capabilities, or chip-fly-back protection where necessary. Choose a silencer nozzle where hearing protection is important.
Thrust – Low or high thrust required to move debris?Choose a safety air gun that delivers appropriate thrust for the surface to be cleaned; low thrust for light debris; high thrust for heavy or stubborn debris.
