The PFA-AG is a high-efficiency pre-pocket filter designed for gas turbine intake systems, capturing coarse and medium particles, salt aerosols and moisture before they reach downstream high-efficiency filters. It is built for high-velocity airflow in wet and dry conditions and provides an OEM-equivalent /Altair® replacement for offshore, coastal and onshore sites, with non-shedding polyester media and a stainless-steel frame.
The four pockets use non-shedding polyester media in a strong stainless-steel frame, helping prevent fibre release and maintain shape at high air velocities. The synthetic media handles wet, humid, sea spray and dry conditions, while its cleanable design helps reduce replacement costs.

From purchase order to delivery on site. Every PFA–AG is built, checked and shipped by our own team.
Common questions about PFA–AG.
The PFA-AG is a high-efficiency pre-pocket filter designed for gas turbine and wind turbine air intakes, gas and diesel engines, marine propulsion and industrial HVAC systems. It uses non-shedding bonded polyester pockets to provide dependable filtration in offshore, onshore and coastal environments.
Yes. The PFA-AG is an OEM-equivalent replacement compatible with Altair System 2, Altair Neptune and Altair Vega. It can be supplied as a compatible replacement for OEM part numbers PFA/001516F and PFA/002849F, with the filter specification and dimensions matched to the existing installation.
Yes. The PFA-AG is designed to perform in demanding industrial and marine environments. Its stainless steel frame, silicone-free synthetic media and cleanable design support reliable filtration in humid conditions, while the filter can operate at temperatures up to 80°C without its performance being affected by humidity.
The PFA-AG pre-pocket filter is designed for industrial air filtration systems that require an initial filtration stage before a downstream coalescer or high-efficiency filters.
The PFA-AG can be matched to suitable industrial HVAC, air handling, gas turbine ventilation and industrial air intake systems where its dimensions and filtration performance meet the installation requirements.
Yes. The PFA-AG can be supplied as a replacement-by-specification or OEM-equivalent pre-pocket filter when the original part number, dimensions, airflow, pocket configuration and required performance are provided.
Yes. Send the existing OEM or manufacturer part number, together with filter dimensions and available technical information. This can be used to assess the appropriate Airguard Envirocare replacement.
Using a suitable pre-pocket filter can reduce the amount of larger particulate contamination reaching downstream high-efficiency filters. The final filtration arrangement should be selected according to the system design and operating environment.
Both PFA-AG and PBR-AG belong to Airguard Envirocare's pre-filtration range. The appropriate filter should be selected according to the existing part number, dimensions, airflow, pocket design and required filtration performance.
PFA-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 PFA-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 FAQ material does not identify a specific gas-turbine air intake system for this product; use it only where its published dimensions, airflow and filtration requirements match the installed system.
Yes. Airguard Envirocare can provide available technical information for PFA-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, PFA-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 PFA-AG.
