3M 7100228104 Spray Gun 2 Qt Composite Npsm 20 Psi

Product Description

The 3M 7100228104 is a composite-body gravity or pressure-feed spray gun designed for paint application in professional and trade finishing environments. Built with a composite body for reduced weight and corrosion resistance, this spray gun accepts air supply through an NPSM-threaded inlet and operates at a maximum pressure of 20 psi. The 2-quart capacity cup provides sufficient material volume for continuous surface coverage without frequent refills. Each unit ships as a complete assembly including the spray gun and air valve, ready for immediate use in body shop, industrial coating, or finish carpentry workflows.

This spray gun is suited for professional painters, auto body technicians, and finishing contractors working with water-based or solvent-based coatings. The composite construction keeps overall tool weight low, reducing operator fatigue during extended spraying sessions. The NPSM air inlet is a standard thread form compatible with typical shop air fittings. At 20 psi maximum operating pressure, this gun is configured for low-pressure application work, making it appropriate for fine finish coatings where atomization control is critical.

Key Features

• Composite body construction reduces weight and resists corrosion from solvents and water-based materials
• 2-quart cup capacity supports extended spray sessions with fewer material refills
• NPSM-threaded air inlet fits standard shop air supply connections
• 20 psi maximum operating pressure suited for low-pressure fine-finish applications
• Includes spray gun and air valve as a complete ready-to-use assembly

Compatibility

Designed as an OEM-style spray gun for professional paint application setups using standard NPSM air supply connections and low-pressure finishing systems.

Installation Notes

Installation and setup should be performed by a qualified painter or finishing technician familiar with compressed air spray equipment. Shut off and bleed the air supply line before connecting or disconnecting the gun from the air source. Verify that the shop air regulator is set below the 20 psi maximum before operation. Clean all fluid passages thoroughly after each use to prevent coating buildup and maintain consistent atomization performance.
