Features

• Use with 1107540, 1107577

Imer Air Pipe with Valve for Spraying Gun is a genuine IMER accessory designed to supply and control compressed air to IMER spray guns used with mortar, stucco, grout, fireproofing, and coating pumps. Typically sold under part number 3225598, this air pipe and valve assembly connects between the compressor and the spray gun, giving the operator precise air control right at the gun for consistent, high‑quality spray patterns on every job.

What Is the Imer Air Pipe with Valve for Spraying Gun?

The Imer Air Pipe with Valve for Spraying Gun is listed by Contractors Direct as “Imer Air Pipe with Valve for Spraying Gun, 3225598,” described as an air hose/pipe and valve set used with IMER spray guns. IMER’s Mortar Spraying & Conveying Line documentation identifies:

• Part number 3225598 – Air pipe with valve for spraying gun.

In IMER’s spray and pump systems, this component is an air line with an integrated shut‑off/adjustment valve that feeds compressed air to the spray gun. It is part of the accessory package used with IMER plaster sprayers, grout pumps, and mixer‑pumps to atomize material and control the spray pattern.

How the Air Pipe with Valve Fits into IMER Spray Systems

IMER pumps like the Mighty Small 50, Koine, and Step series are designed to mix and pump mortars, plasters, waterproofing, and coatings through material hoses to a spray gun, while a separate air hose supplies compressed air. In this setup:

• The material hose carries the mortar, stucco, grout, or coating from the pump to the gun.

• The air pipe with valve carries compressed air from the compressor to the spray gun.

• At the gun, air and material meet at the nozzle to create the spray pattern.

The Imer Air Pipe with Valve for Spraying Gun is the dedicated air line that:

• Connects to IMER‑specified compressors via couplings (often Geka quick couplers in IMER kits).

• Connects to IMER spray guns such as 1107540, 1107549, 1107577, 1107011, and other Pro‑Tek line guns.

• Gives the operator immediate control over air flow via the integrated valve, so they can fine‑tune atomization based on material and finish requirements.

Technical Role of the Air Pipe and Valve

In a spray pump system, compressed air is crucial for proper finish. The Imer Air Pipe with Valve for Spraying Gun provides:

• Air delivery

  • Transports compressed air at the correct diameter and length for IMER systems, typically matching hose standards like 13 mm air hose used in IMER kits.

• On‑gun air control

  • Built‑in valve allows the operator to open, close, or partially throttle air flow at the gun, not just at the compressor.

  • Supports quick pressure adjustments when switching materials (e.g., from thick mortar to thin coating).

• Spray pattern optimization

  • Proper air flow is essential for the spray guns’ deflectors and nozzles to produce even, well‑atomized coats.

  • Insufficient air causes coarse, uneven spray; excessive air can cause overspray and rebound. The valve helps dial in the sweet spot.

The air pipe and valve work together with the spray gun’s own air regulators (on models like 1107568 and 1107011) to give multi‑stage air control for demanding applications.

Typical IMER Kits That Use the Air Pipe with Valve

IMER’s S 50 Airless and mortar spraying documentation shows several kits where the air hose/pipe and valve are integral pieces of the system:

• Smoothing and grouting kit – 1107010

  • Includes spray gun, deflectors, 10 + 5 m material hoses, 16 m air hose Ø 13 with Geka couplings, and cleaning tools.

• Painting kit – 1107009

  • Includes spray gun with Ø5–Ø6 deflectors, 10 m material hose, 16 m air hose Ø 13 with Geka couplings, nozzle cleaner, and sponge.

• Mortar and fireproofing kit – 1107005

  • Includes spray gun, deflectors for traditional and premixed materials, 15 m material hose, and 16 m air hose Ø 13 with Geka couplings.

In these systems, the Imer Air Pipe with Valve for Spraying Gun (3225598) serves as the controlled air feed line to the gun, using the same style of air hose and couplings described in the kits.

Compatibility with IMER Spray Guns

The Imer Air Pipe with Valve for Spraying Gun is compatible with the full range of IMER Pro‑Tek spray guns used on mortar, stucco, grout, fireproofing, and finishing systems, including:

• 1107540 – Ø 25 F spray gun for traditional/premixed plaster with Ø14 deflector.

• 1107549 – Ø 25 F spray gun, 1.43 m long for fireproofing and premixed plaster.

• 1107568 – Ø 25 F spray gun with no‑spreading ball valve and air flow regulator.

• 1107577 / 1107641 – Ø 35 spray guns for mortar and fireproofing.

• 1107011 – Spray gun for finishing coat, filling, touch‑pointing, injections without deflectors.

All of these guns require a dedicated air supply line from the compressor, and the 3225598 air pipe with valve is designed as the OEM solution for that role in IMER setups.

Benefits of Using the OEM Imer Air Pipe with Valve

Choosing the genuine Imer Air Pipe with Valve for Spraying Gun offers several advantages over generic air hoses and valves:

• Designed for IMER pressure and flow ranges

  • Dimensions and materials match IMER pump and compressor specifications, ensuring adequate flow and safe working pressures.

• Proper couplings and fittings

  • Uses the correct coupling standards (such as Geka or cam‑type connectors) that match IMER equipment, reducing leak and misfit risks.

• Integrated control at the gun

  • The valve location is optimized for comfortable use, allowing the operator to adjust or shut off air instantly during spraying.

• Reliability and durability

  • OEM parts are tested to withstand abrasive jobsite conditions, frequent pressurization cycles, and exposure to overspray and mortar dust.

Using the recommended air pipe helps maintain consistent performance, reduces troubleshooting, and keeps IMER systems operating as designed.

Typical Applications for the Imer Air Pipe with Valve

Because it is a core accessory for IMER spray guns, the Imer Air Pipe with Valve for Spraying Gun is used in a wide range of applications, such as:

• Conventional and premixed plaster spraying

  • Traditional stucco, premixed plaster, and base coats on interior and exterior walls.

• Fireproofing

  • Spraying fireproofing mortars and materials using long guns and heavy‑duty deflectors.

• Waterproofing and protective coatings

  • Applying waterproofing products and specialized coatings with pump‑and‑spray setups.

• Smoothing and decorative finishes

  • Fine decorative plasters, smoothing layers, and thin finishing coats.

• Painting and thin coatings

  • Solvent‑free paints and coatings applied with painting kits like 1107009.

• Grouting and injections

  • Controlled‑pressure consolidation injections and panel cavity filling when used with appropriate injection kits.

In all these scenarios, the air pipe with valve helps maintain the right air delivery for optimal finish quality.

Installation and Use Considerations

To get the best results from the Imer Air Pipe with Valve for Spraying Gun:

1. Match hose length and size to the system

   • Use IMER‑recommended lengths and diameters (often 13 mm for air hose) to avoid pressure drops.

2. Connect with correct couplings

   • Ensure the air pipe is connected to the compressor and the gun using the proper quick couplers supplied or specified by IMER.

3. Set compressor pressure per material

   • Follow material data sheets and IMER pump manuals to set regulator pressure at the compressor.

4. Fine‑tune with the on‑gun valve

   • Use the valve on the air pipe and the gun’s own air control (if present) to adjust atomization while test‑spraying, before working on the final surface.

5. Inspect regularly for wear and leaks

   • Check the hose and valve for cracks, abrasion, or leaks, and replace if damaged to avoid inconsistent spray or loss of pressure.

Proper setup ensures safe operation and a uniform, professional finish.
