Replacing a CP2 coalescer panel filter requires more than matching its part number or external dimensions. Engineers and procurement teams should verify the filtration system, panel depth, airflow, media construction, frame material and operating environment. The Airguard CP2-AG is an OEM-equivalent replacement option for compatible Altair and other specified intake systems. | ||

What Is a CP2 Coalescer Panel Filter?
A CP2 coalescer panel filter is designed to capture moisture droplets, salt aerosols and liquid contaminants from incoming air. It is used in demanding air intake applications where moisture and airborne contaminants can affect downstream filtration equipment and gas turbine components.
Unlike a conventional particulate filter, a coalescer uses specialised media to encourage small liquid droplets to combine into larger droplets. These can then drain or be carried away through the filtration system, depending on its design and operating arrangement.
CP2-style panels are particularly relevant to:
Gas turbine air intake systems
Offshore oil and gas installations
Marine propulsion equipment
Coastal power generation facilities
Offshore wind turbine applications
Industrial engine and HVAC air intakes
The correct replacement must maintain compatibility with the existing filter housing and meet the operating requirements of the installation.
Why CP2 Filter Replacement Requires Technical Verification
An OEM part number provides a useful starting point, but it does not confirm every detail required for a successful replacement. Two panels may have similar external dimensions while differing in media construction, depth, airflow capacity or sealing arrangements.
These differences can affect pressure drop, moisture separation and installation.
Before approving a replacement, engineers should review the following:
Verification point | What to check | Why it matters |
|---|---|---|
OEM reference | Existing part number and system | Establishes the correct product reference |
Dimensions | Height, width and depth | Confirms housing compatibility |
Airflow | Required flow rate and face velocity | Helps avoid excessive resistance |
Media | Polyester, synthetic or metal mesh | Determines the filtration and coalescing arrangement |
Frame | Stainless steel or other specified material | Supports mechanical and environmental suitability |
Sealing | Gaskets, clips and adjoining arrangements | Reduces the risk of air bypass |
Operating conditions | Moisture, salt, dust and temperature | Helps establish material and media suitability |
A replacement should be assessed against the complete specification rather than selected through a part-number match alone.
Airguard CP2-AG: OEM-Equivalent Replacement Specifications
The Airguard CP2-AG is designed as an OEM-equivalent coalescer panel for compatible gas turbine intake systems. It is specified for Altair System 2, Altair Neptune and Altair Vega applications, with additional listed equivalents and systems.
Its construction combines polyester coalescing media with plastic-coated wire mesh in a V-pleated arrangement. A stainless-steel frame supports the assembly.

These are published product specifications. Final suitability should still be checked against the original equipment requirements and the operating conditions of the installation.
How the CP2-AG Construction Works
The CP2-AG uses a high-efficiency polyester mat positioned between two layers of plastic-coated wire mesh. The assembly is pleated to create a corrugated structure.
This construction provides several functional benefits:
Increased media area: The V-pleated arrangement provides more effective filtration area within the panel format.
Structural support: The mesh helps support the media and maintain the panel's construction.
Moisture coalescing: The polyester media supports the capture and combination of liquid aerosols.
Mechanical filtration: The panel also captures airborne particulate contaminants.
Frame stability: The stainless-steel frame provides structural support during installation and operation.
The combination is intended for applications where airflow, moisture and salt exposure must be considered together.
Which OEM Systems and Part Numbers Does CP2-AG Replace?
The CP2-AG product specification identifies compatibility with several air intake systems and equivalent panel references.
System or manufacturer reference | Listed compatibility | |
|---|---|---|
Parker Hannifin / Altair | System 2 | |
Parker Hannifin / Altair | Neptune | |
Parker Hannifin / Altair | Vega | |
Parker Hannifin / Altair | Aquila | |
Airfil | GT2 | |
Veotec | CP2 coalescer panels | |
Wozair | CP2 coalescer panels | |
Sterling Thermal | Listed equivalent panel references |
The product page also lists the following OEM references:
K8581
K0840
K26035
K26462
332-013
332-016
These references should be treated as cross-reference starting points, not as permission to assume that every panel carrying a similar designation is interchangeable. Confirm the exact system, dimensions and configuration before placing an order.
CP2 Coalescer Panel Filter Applications
The CP2-AG is intended for industrial environments where liquid aerosols, moisture and airborne particles can enter the intake system.
Offshore and Marine Installations
Marine and offshore equipment can be exposed to salt mist, humidity and moisture-laden air. These contaminants can contribute to corrosion and affect downstream filtration components.
A coalescer panel helps manage liquid aerosols before air reaches subsequent filtration stages. Frame material, sealing and media condition are important considerations in these environments.
Gas Turbine and Power Generation Systems
Gas turbine intake systems require filtration arrangements suited to their airflow and environmental conditions. A coalescer panel may form part of a staged filtration arrangement, helping manage moisture and liquid aerosols before downstream filters.
The replacement must match the intake system's required airflow, installation dimensions and pressure-drop limits.
Industrial and Wind Applications
Industrial engines, offshore wind installations and other air intake applications may experience varying combinations of dust, moisture and salt exposure.
The correct panel specification depends on the equipment design and the contaminants present at the installation.
CP2 Filter Replacement: What Should Engineers Check Before Ordering?
A structured replacement process helps reduce the risk of receiving a filter that fits physically but does not meet the required operating specification.
Confirm the existing reference — Record the part number from the installed filter, equipment documentation or maintenance records. Check whether the reference relates to the complete panel or a specific component.
Measure the existing panel — Confirm the height, width and depth. Also check the available housing space and any retaining arrangements. Do not rely on approximate measurements where a precise fit is required.
Verify airflow requirements — Review the design airflow and expected face velocity. The replacement should operate within the limits specified for the intake system.
Compare media and construction — Check the media type, mesh arrangement, frame material and pleat design. These details help establish whether the proposed replacement is suitable for the installation.
Review sealing and installation details — Inspect gaskets, clips, adjoining panels and the direction of installation. Poor sealing can allow unfiltered air to bypass the media.
Confirm the operating environment — Provide information about salt exposure, humidity, moisture, dust and operating temperature. These conditions can influence the material and construction requirements.
Request technical confirmation — Before issuing a purchase order, obtain confirmation that the proposed replacement matches the required system and specification.
CP2-AG vs a Generic Coalescer Panel Filter
A generic coalescer panel may appear similar to an existing CP2 filter, but visual similarity does not establish technical equivalence.
Comparison factor | CP2-AG | Generic replacement |
|---|---|---|
System references | Specific OEM-equivalent systems listed | Compatibility may be unclear |
Media construction | Polyester mat with plastic-coated wire mesh | Depends on supplier |
Frame | Stainless steel | Depends on specification |
Panel depth | 22 mm / 50 mm options | Must be verified |
Flow specification | Published at 9 m/s | Requires confirmation |
Dimensions | Standard and non-standard options | Must be verified |
Technical documentation | Product specification available | Depends on supplier |
The important distinction is not whether a replacement looks like the original. It is whether its documented construction and operating characteristics meet the requirements of the equipment.
