Wagner GM 4100AC AirCoat Manual Spray Gun
Small Gun. Serious Finish.
A spray gun does not have to be big, heavy, or complicated to earn its place in a finishing operation. It has to feel right in the operator’s hand, atomize the coating properly, and keep doing both through a full production shift.
The Wagner GM 4100AC AirCoat manual spray gun is a compact, lightweight applicator designed for professional metal, plastic, and wood finishing. Its smaller grip, low trigger force, and balanced 600-gram design make it especially comfortable for operators with smaller hands.
Wagner AirCoat technology combines high-pressure material delivery with supporting atomizing air. The fluid pressure does most of the work, while Wagner’s air-guidance system softens and shapes the spray pattern. The result is controlled atomization, a soft spray pattern, and the finish quality production work demands.
This is the kind of tool that proves a simple point: when the gun fits the operator and the coating is properly controlled, better work becomes easier to repeat.
Features That Earn Their Keep
-
Compact GM 4100AC Design:
The smaller gun body fits comfortably in smaller hands and provides better control in detailed or confined finishing applications.
-
Lightweight 600-Gram Construction:
Reduces the weight operators must carry through long production shifts, helping limit hand, wrist, and arm fatigue.
-
Low Trigger and Holding Forces:
Makes repeated spraying more comfortable and helps the operator maintain control throughout the working day.
-
Wagner Air-Guidance System:
Coordinates supporting air around the fluid stream for optimum atomization and dependable pattern control.
-
Soft AirCoat Spray Pattern:
Uses lower material pressure with supporting atomizing air to produce a soft, controllable pattern for professional finish quality.
-
Forged Gun Housing:
Provides the strength and reliability required for demanding daily production conditions.
-
Interchangeable Air Caps:
Allows the gun to be adapted for compatible waterborne or solvent-containing coatings using the appropriate air-cap configuration.
-
Multiple Nozzle Options:
Supports nozzle sizes from 0.007 to 0.023 inch for materials ranging from lower to very high viscosity.
-
Maximum Material Pressure of 250 Bar:
Handles fluid pressure up to approximately 3,626 PSI for properly configured AirCoat applications.
-
Durable Wetted Components:
Stainless steel, carbide, polyamide, polyacetal, and PTFE components support dependable operation with compatible coatings.

A Gun Should Fit the Work—and the Person Doing It
The operator is the one who carries the gun, pulls the trigger, follows the contours, and answers for the finished part. Giving that person a lighter, properly sized applicator is not a luxury. It is a practical way to support better control, reduce fatigue, and produce more consistent work.
The Wagner GM 4100AC does not try to impress the operator with extra weight or unnecessary complication. It simply provides a compact grip, dependable construction, and the AirCoat control required to put down a professional finish.
