Description

The Graco D-Gun Spray Foam Gun (Model D, part 295530) is engineered for professional small- to mid-output foam applications such as interior stud-wall spraying or insulation inside truck and trailer bodies. With interchangeable mixing chambers in 55, 62 or 70 size you can choose the right chamber for your application: the 55 yields approx. 8-inch (20.3 cm) pattern at 18-20 in away and about 6-8 lb/min (2.7-3.6 kg/min) output. The 62 offers about 9-inch pattern and 7-10 lb/min output. The 70 delivers about 10-inch pattern and 9-12 lb/min output. The air cap allows easy cleaning of the purge rod, the lightweight design reduces fatigue, and the built-in pattern control knob gives fine tuning for spray distribution. Mechanically self-cleaning, the D-Gun eliminates costly solvent-flushing and keeps downtime minimal. Use the Graco D-Gun when you need reliable foam output with adjustable pattern size, reduced operator strain and efficient cleaning in truck-body, trailer or cavity-insulation applications.

Frequently Asked Questions

Service & Support

Can I switch between the 55, 62 and 70 mix chambers on the Graco D-Gun for different spray widths?

Yes, the Graco D-Gun supports the 55, 62 and 70 mix chamber sizes (model numbers 295530 for D-55, 295532 for D-62, 295533 for D-70) so you can swap modules to achieve different pattern diameters and output rates.

What cleaning or purge procedure is needed when switching materials or finishing the job with the Graco D-Gun?

The Graco D-Gun features a mechanically self-cleaning design, meaning you don’t need costly solvent-flushing each time; the air cap also facilitates cleaning of the purge rod. However, users should still follow the manufacturer manual for changeovers and scheduled maintenance.

If I’m working at a higher output requirement than 9-12 lb/min, is the Graco D-Gun still suitable?

The Graco D-Gun is rated for about 9-12 lb/min output and ~10-inch pattern with the 70 mix chamber. For significantly higher output or wider patterns, a larger gun model may be more appropriate
