Cox AirFlow 3 VBA 400B Pneumatic Dispensing Gun, 400mL 1:1 and 2:1

Description

The Cox AirFlow 3 VBA 400B is a two-component pneumatic dispensing gun that handles 200mL and 400mL side-by-side Total System cartridges at both 1:1 and 2:1 mix ratios. Air-powered flow keeps two-part adhesives, sealants, and epoxies metering evenly, so mixed material comes out at the correct ratio from start to finish.

Cox AirFlow Pneumatic Dispensing Gun Overview

This model uses the AirFlow Series 3 air system, giving smooth, regulated output for standard-viscosity two-part materials. Because the trigger meters air pressure rather than muscle, operators hold a consistent bead through long runs without fatigue. Support for both 1:1 and 2:1 cartridges makes one tool cover a wider range of jobs on the bench or in the field.

Applications for This Pneumatic Dispensing Gun

The AirFlow 3 VBA 400B suits bonding, sealing, and potting in sign and display, synthetic turf, pool, and construction work that calls for 1:1 or 2:1 two-part cartridges. Air actuation shines on repetitive dispensing and on materials that are hard to push by hand. Pair it with the correct static mixing nozzle from our dispensing guns, mixers, and nozzles category.

Setup and Nozzle Selection

Correct nozzle choice drives mix quality on every shot. Load the cartridge, fit a fresh static mixing nozzle sized for the material and mix ratio, then set the air regulator to the lowest pressure that gives a clean, continuous bead. Purging a short length before the first application clears any off-ratio material at the tip and confirms the two parts are fully blended before they reach the work.
