Description
The Cox AirFlow 3 PPA 300B is a pneumatic dispensing gun for two-component adhesive and sealant cartridges. This configuration is set up for 450 mL side-by-side cartridges at a 2:1 mix ratio. Air power keeps bead output steady through longer production runs, while the trigger and regulator let the operator control material flow without the fatigue of a high-thrust manual applicator.
Where this pneumatic dispensing gun fits
Use this gun on assembly benches, fabrication lines, repair cells, and cartridge dispensing stations where compressed air is already available. It fits jobs that need repeatable beads from filled epoxies, urethanes, acrylics, silicones, and other two-component materials. The AirFlow 3 PPA 300B layout is useful when a shop wants a controlled pneumatic tool instead of hand force, especially on wide beads, long joints, or adhesive systems that require steady pressure across the full cartridge stroke.
The tool is also helpful when several operators share the same cartridge platform. Matching the gun to the cartridge volume and ratio keeps the plungers moving evenly, protects the static mixer from pressure spikes, and reduces the stop-start bead shape that can happen when a manual tool is pushed near its limit.

How this pneumatic dispensing gun handles material
The pneumatic drive is made for low to medium viscosity materials and factory use where air supply is part of the workstation. Cox product resources place the operating pressure at 6.8 bar (100 psi) with 40 liters per minute air consumption. The gun frame holds the cartridge set in alignment, and the air circuit applies force through the plungers so both sides feed into the mixer at the intended ratio. That matters on two-part products because off-ratio dispensing can leave soft spots, uncured material, or weak bond lines.
For application setup, confirm that shop air is clean and regulated before connecting the tool. Load the cartridge set squarely, purge both sides before attaching the mixer, then make a short test bead to confirm ratio, flow rate, and trigger response. Keep spare mixers near the station because two-component material can cure inside a static mixer during pauses. At shutdown, follow the adhesive maker’s purge and storage practice for the cartridge, then wipe the gun nose and plunger contact points so cured residue does not affect the next setup.
