Description
The Cox AirFlow 1 CBA 25 R50 1:1 dispenser is a compact, air-powered, two-component dispenser for 50 mL A-System and B-System square back cartridges at a 1:1 ratio. 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, minimum trigger pressure, easy loading breach, and quick exhaust valve give the operator control over the bead and help prevent run-on.
Older paperwork may list this tool as A25 or DP2 A025-01. The current part number is DP2C 050-01-110-111.

Performance in Production
- The adjustable air regulator sets output pressure anywhere up to the 75 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.
- The easy loading breach speeds up cartridge changes on a busy bench, and Cox lists secure cartridge fit as a benefit of the design.
- The quick exhaust valve helps 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.
- The 4.1 in (105 mm) frame keeps the tool compact for tight benches and small assemblies, and it is rated for low to medium viscosity materials.
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 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 1 CBA 25.
- Confirm the cartridge is a 50 mL square back A-System or B-System cartridge that runs at 1:1. For 2:1 cartridges, use the 2:1 AirFlow 1 version listed under Related Products.
- Load the cartridge using the easy loading breach and connect shop air at or below the 75 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. The quick exhaust valve helps 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 1 CBA 25 R50 1:1 dispenser 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 1 CBA 25 R50 1:1?
The old item number is A25 and the old material description is DP2 A025-01. The current part number is DP2C 050-01-110-111, and the medmix material number is 159359.
Which cartridges does it fit?
It fits square back 50 mL cartridges at 1:1, which are the MIXPAC A-System and B-System 50 mL formats. For 2:1 cartridges, use the AirFlow 1 dispenser for 2:1.
What is the difference between the AirFlow 1 CBA 25 and the AirFlow 2 CBA R50?
The AirFlow 1 CBA 25 is the more compact tool with a higher pressure limit (75 psi against 50 psi) and an aluminum handle, and this version is set up for one ratio. The AirFlow 2 CBA R50 covers 1:1 and 2:1 in one item.
Is there a manual or battery option for 1:1 cartridges?
Yes. The Chem-Set PAK-50 manual gun runs 50 mL square back cartridges at 1:1 and other ratios, and the Chem-Set battery gun runs 1:1 square back cartridges.
What air pressure does it need?
Maximum pneumatic pressure is 75 psi (5.2 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.
Are the components CE and REACH approved?
Yes. Cox lists CE and REACH as the tool component approvals.
