Description
The Cox AirFlow 3 dispenser runs 400 mL two-component cartridges at a fixed 2:1 mix ratio, trading a hand trigger for shop air so bead output stays even from the first stroke to the last. The VBA-400B frame accepts standard 400 mL side-by-side cartridges and drives the piston with pneumatic force instead of a ratchet mechanism, which matters on long production runs where hand fatigue changes bead consistency partway through a shift.
Where the Cox AirFlow 3 dispenser fits
Shops running structural adhesives, potting compounds, and two-component sealants through 400 mL cartridges use the AirFlow 3 to hold mix ratio steady across a full cartridge, not just the first few strokes. It suits production cells with a regulated air drop already in place, repair stations that cycle through several cartridges per shift, and any 2:1 two-component job where an uneven push between the two plungers would throw off cure or bond strength.
How the Cox AirFlow 3 dispenser performs
Running on regulated shop air up to roughly 100 psi (6.8 bar), the gun develops close to 2.2 kN of thrust at the piston, enough to move medium-viscosity two-component material through a static mixer without the operator forcing the stroke. The frame measures about 8 in (203 mm) and the tool weighs close to 4.8 lb (2.2 kg), light enough for sustained one-handed work along a seam or joint.

Pair the gun with a 2:1 static mixer and matching cartridge from Chemical Concepts dispensers, mixers, and nozzles. Cox documents the full AirFlow pneumatic line, including service parts and air fittings, at Cox Dispensers. Confirm the 2:1 ratio matches the cartridge before loading, since a ratio mismatch wastes material and can produce an unusable bead. Keep the air line regulated to the gun’s rated pressure, bleed trapped air before each new cartridge, and wipe cured material from the piston rod and nose area between shifts.
