The PFAH-AG Pre-Pocket Filter is engineered for gas turbine air intake systems in offshore and coastal environments, where it captures coarse dust and salt at the primary filtration stage before they reach high-efficiency downstream filters. Made from non-shedding, thermally bonded polyester, it is available in mixed-pocket, four-pocket and three-pocket configurations to suit different housings and dust-loading conditions. Built as an OEM-equivalent replacement for Altair-specified intake systems, the PFAH-AG offers high dust-holding capacity and helps extend downstream filter life and reduce change-outs.
The three- and four-pocket filters use non-shedding, thermally bonded polyester media to protect downstream high-efficiency filters. They feature a stainless-steel frame with a 22 mm header, with standard 597 × 597 × 400 mm four-pocket sizes, custom sizes, clips and seals available.

Common questions about PFAH–AG.
The PFAH-AG is a high-efficiency pre-pocket filter designed to protect downstream high-efficiency filters in demanding air intake systems. It is suitable for gas turbine and wind turbine intakes, gas and diesel engines, marine propulsion and industrial HVAC applications. Its non-shedding bonded polyester pockets provide reliable filtration in offshore, onshore and coastal environments.
Yes. The PFAH-AG is an OEM-equivalent filter compatible with Altair System 2, Altair Neptune and Altair Vega air intake systems. It can be supplied as a compatible replacement for OEM part numbers PFAH/001516F and PFAH/006058F, subject to specification and dimensional matching.
The PFAH-AG offers 93% efficiency up to 5 microns, high dust-holding capacity and reliable performance at high air velocities in wet and dry conditions. Its 100% silicone-free, non-shedding polyester media and stainless steel frame help extend the service life of downstream filters in demanding gas turbine and industrial air intake applications.
Yes. The PFAH-AG industrial pre-filter can be matched to suitable gas turbine and industrial air intake applications where a pre-filtration stage is required to reduce the contaminant load on downstream filters.
Yes. The PFAH-AG can be assessed as an OEM-equivalent or replacement-by-specification pre-pocket filter. Provide the existing filter part number, dimensions, pocket quantity, airflow and filtration requirements for accurate matching.
Existing OEM, Parker®, Altair® or other manufacturer part numbers can be submitted for replacement matching. A specific cross-reference should only be published once it has been verified against the original filter specification.
A properly selected pre-pocket filter captures larger airborne particles before they reach finer downstream filters. This can reduce contaminant loading on coalescer and high-efficiency filtration stages and support longer service intervals, depending on operating conditions.
The correct choice between PFAH-AG and PFA-AG should be based on the existing filter specification, dimensions, pocket construction, airflow and required filtration performance. Sending the installed filter part number or technical drawing is the most reliable way to identify the correct replacement.
The available product information identifies Altair System 2, Neptune and Vega compatibility.
PFAH-AG should be selected according to the environmental conditions stated in its product specification, including factors such as dust, moisture, salt, humidity, temperature and airborne contamination where applicable. The installed system and required filtration performance should be checked before selection.
Where PFAH-AG is identified as Altair-compatible, Airguard Envirocare positions it as an OEM-equivalent or specification-matched replacement. Exact compatibility should be confirmed against the installed filter's part number, dimensions and required performance. The available product information identifies Altair System 2, Neptune and Vega compatibility.
Yes. Airguard Envirocare can provide available technical information for PFAH-AG, including technical datasheets, technical drawings and other relevant information on request.
The stated manufacturing origin is the United Kingdom.
Depending on the product, order requirements and delivery location, PFAH-AG can be delivered in approximately 2 to 7 working weeks.
Use of an alternative filter should not be described as automatically voiding a gas turbine warranty. Warranty terms are set by the turbine OEM and the applicable contract, so customers should confirm the requirements with the OEM or operator before installation. Where this product is used as an OEM-equivalent replacement, its dimensions and performance specifications should be verified for the specific installation.
Yes. Airguard Envirocare offers a 12-month manufacturer's warranty for PFAH-AG.
