Description
The Cox AirFlow 2 CBA R50 pneumatic dispenser is an air-powered, two-component dispenser for 50 mL square back cartridges in 1:1 and 2:1 ratios. It is used for bead dispensing in bonding, sealing, and shimming work, where air pressure replaces hand pressure on the trigger. An adjustable air regulator, air return, and quick exhaust valve give the operator control over the bead and help prevent run-on.
Older paperwork may list this tool as A50/1:2 or DP2 A050-01/2. The current part number is DP2C 050-12-070-211.

Performance in Production
- The adjustable air regulator sets output pressure anywhere up to the 50 psi maximum, so the operator can match the bead to the material instead of fighting the trigger.
- Minimum trigger pressure keeps trigger effort light across a shift of repeat dispensing, which cuts hand fatigue on 50 mL cartridge work.
- Air return and the quick exhaust valve help stop flow when the trigger is released, which prevents run-on at the end of a bead.
- Air consumption is 40 liters per minute, so size the shop air line and regulator for that draw before you put the tool on a bench with other air tools.
- At 4.81 lb (2.2 kg) with a glass fiber reinforced nylon handle and cartridge holder, the tool stays light enough for bench or line work.
- The tool is rated for low to medium viscosity materials. For heavier pastes, call us before you order.
Common Applications
- Bonding with 50 mL two-component cartridges
- Sealing with 50 mL two-component cartridges
- Shimming with 50 mL two-component cartridges
- Bead dispensing of 1:1 and 2:1 cartridge materials where air control is preferred over hand pressure

How Pneumatic 50 mL Cartridge Dispensing Works
A pneumatic dispenser uses shop air to push the cartridge plungers, so the operator controls the bead with the regulator and trigger instead of squeezing a manual gun. The steps below follow the controls on the AirFlow 2 CBA.
- Confirm the cartridge is a 50 mL square back A-System or B-System cartridge that runs at 1:1 or 2:1. For 4:1 or 10:1 cartridges, use the 4:1 and 10:1 version listed under Related Products.
- Connect shop air and keep the supply at or below the 50 psi maximum.
- Set the regulator low, then raise pressure until the bead is steady for your material.
- Fit the mixer nozzle your cartridge system calls for and dispense. Minimum trigger pressure keeps the pull light.
- Release the trigger. Air return and the quick exhaust valve help stop the flow so the bead ends cleanly.
The tool is rated for low to medium viscosity materials and handles bonding, sealing, and shimming beads.
Frequently Asked Questions
What is the Cox AirFlow 2 CBA R50 used for?
It is a pneumatic dispenser for 50 mL two-component cartridges, used to apply beads for bonding, sealing, and shimming. Pneumatic dispenser, pneumatic dispensing gun, and air-powered cartridge gun all describe the same kind of tool.
What is the old part number for the AirFlow 2 CBA R50?
The old item number is A50/1:2 and the old material description is DP2 A050-01/2. The current part number is DP2C 050-12-070-211, and the medmix material number is 159361.
Which cartridges does the AirFlow 2 CBA R50 fit?
It fits square back 50 mL cartridges at 1:1 and 2:1, which are the MIXPAC A-System and B-System 50 mL formats. Cox lists the broader AirFlow 2 CBA 50 line at 1:1, 2:1, 4:1, and 10:1, and the 4:1 and 10:1 version is a separate item on this site.
Does it fit round back S-System cartridges?
No. For S-System round back cartridges, use the S50 dispenser for 1:1, 2:1, and 3:2 or the S50 dispenser for 10:1.
What air pressure does it need?
Maximum pneumatic pressure is 50 psi (3.5 bar). Air consumption is 40 liters per minute, and the adjustable regulator sets the working pressure below that limit.
What viscosity can it dispense?
It is rated for low to medium viscosity materials. If your material is thicker, call us before ordering.
Does it work with cartridges larger than 50 mL?
No. The cartridge capacity is 50 mL (1.7 oz). For 310 mL, 400 mL, 600 mL, or sausage packs, browse our dispensers, mixers, and nozzles.
Are the components CE and REACH approved?
Yes. Cox lists CE and REACH as the tool component approvals.
