Contractors searching for a low-pressure spray foam applicator may encounter several descriptions for the Titan ProPurge: two-component gun, plural-component gun, air-purge gun, or even “air-mixed spray foam gun.” These phrases do not all mean exactly the same thing. Understanding how the gun, hose assembly, air supply, and Maze nozzle work together makes it easier to order the correct equipment and avoid compatibility surprises.
What is the Titan ProPurge?
The Titan ProPurge is a low-pressure applicator for two-component polyurethane spray foam. It receives the two liquid components separately and directs them into a replaceable static-mixing nozzle at the front of the gun.
Titan advertises Helix LP system output up to 15 pounds per minute; that is a system capability, not a guaranteed gun-only production rate. Its maximum fluid-pressure rating is 145 psi, and its maximum air-pressure rating is 115 psi. Those figures are equipment limits, not universal operating settings. Actual flow and pressure depend on the proportioner, chemical temperature and viscosity, hose size and length, nozzle condition, system restrictions, and material manufacturer’s requirements.
Individual gun package: MPN 153951; UPC 024964276189. Titan’s six-unit master carton is labeled top-level P/N 0153951.

Air purge is different from air mixing
“Air-mixed spray foam gun” is a common search phrase, but it is not the most precise description of the ProPurge process. The two polyurethane components mix inside the disposable Maze-style static mixer. Compressed air serves the gun’s purge function; it does not replace the physical mixing path inside the nozzle.
This is why the nozzle is a functional part of the application system rather than merely a spray tip. Its internal geometry provides the path through which the two components combine before leaving the gun.
What comes with the gun?
This Foam Solutions Titan ProPurge offer includes the pictured hose assembly. Titan’s literature distinguishes the gun’s attached A-side, B-side, and air hose leads from separate longer whip-hose packages, so compare the photos and confirmed part number when matching an existing setup.
Maze nozzles are not included with the gun. They are operating consumables and must be purchased separately. The separate nozzle listing contains 25 Titan ProPurge Maze static-mixing round nozzles.

Why connection compatibility still matters
Titan identifies the ProPurge as a low-pressure spray foam gun, but “low pressure” does not mean every low-pressure proportioner uses identical fittings, hose arrangements, air connections, or controls.
Before ordering, verify:
- The make and model of the proportioning system
- The A-side and B-side chemical-hose connections
- The available air connection and air supply
- The system’s normal working-pressure range
- Hose routing and component identification
- Material-manufacturer equipment requirements
- The gun and nozzle manufacturer part numbers
If the existing setup is unclear, send Foam Solutions photos of the hose ends, fittings, current gun, and equipment label so the connection requirements can be reviewed before ordering.
Understanding the published ratings
Titan advertises Helix LP system output up to 15 lb/min, but that is a complete-system capability; the gun cannot create output that the rest of the system cannot supply. Pump capacity, pressure stability, temperature, material viscosity, hose restriction, and nozzle condition all affect the delivery rate.
Likewise, the listed maximum pressures should not be treated as target settings. The correct operating range comes from the equipment instructions, chemical technical data, and the complete system configuration. Establish compatibility before connecting or pressurizing new equipment.
Choosing the correct Maze nozzle
The ProPurge uses a Maze static-mixing round nozzle. The terms identify meaningful features:
- Maze refers to the internal mixing path.
- Static mixing means the materials combine through fixed internal geometry rather than a powered mixing mechanism.
- Round identifies the nozzle configuration.
A generic nozzle that looks similar should not be assumed compatible. The connection, internal path, and intended applicator must match. Verify that replacement nozzles are specified for the Titan ProPurge and compare the manufacturer part number.

Which product should you order?
Choose the gun listing if you need the Titan ProPurge applicator and the pictured hose assembly included in this Foam Solutions offer. The gun is $125, or six guns are $700.
Choose the nozzle listing if you already have a ProPurge gun and need replacement Maze static-mixing round nozzles. Each package contains 25 nozzles and costs $125. Six packages—150 nozzles total—are $700.
Both products include free standard shipping to contiguous-U.S. addresses. For a new setup, order the gun and an appropriate supply of Maze nozzles after confirming the connections and system requirements. For an existing ProPurge setup, verify the model and part number before replenishing nozzles.
Quick answers
Does this ProPurge offer include the pictured hose assembly?
Yes. This Foam Solutions gun listing includes the pictured hose assembly.
Does the gun include Maze nozzles?
No. Maze nozzles are sold separately in 25-packs.
Is the ProPurge an air-mixed gun?
Air-mixed is a common search phrase, but air-purge is more accurate. The chemicals mix inside the Maze static-mixing nozzle while compressed air provides the purge function.
