Description
The Cox AirFlow 3 VBA 400A is a high-power pneumatic dispenser kit for two-part 400 mL cartridges. The kit includes plungers covering 1:1, 2:1, 4:1, and 10:1 mix ratios, so a single tool handles the full Mixpac and similar dual-cartridge range without buying a second gun. It also accepts 200 mL cartridges with the appropriate adapter.
Where the Cox AirFlow 3 fits
The VBA 400A targets shops dispensing structural epoxies, acrylics, methacrylates, urethanes, and silicones in two-part cartridges. The S3 air-driven system delivers steady thrust for high-viscosity adhesives that strain manual guns, and the variable-flow trigger gives fine control on placement work. Typical users are countertop fabrication, composite repair, marine, prototype assembly, and field service techs who switch cartridge formats during the day.
How the Cox AirFlow 3 holds up under load
The dispenser is rated for shop-air pressures in the standard 70 to 100 psi range. The aluminum body and steel rod assembly tolerate daily production cycles, and the included thrust assemblies swap without tools. Air consumption stays modest because the trigger meters air flow rather than running continuously.
