Airguard Envirocare PB1-AG is an OEM-equivalent pre-pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega. It helps protect downstream high-efficiency filters in gas turbine air intake systems from dust, salt, and other airborne contaminants.
The PB1-AG pre-pocket filter is engineered for gas turbine air intake systems operating in demanding offshore, coastal and onshore environments. Installed as an initial filtration stage, it captures coarse dust, salt aerosols and airborne particles before they reach the downstream high-efficiency filters.
With a dust-holding capacity of 625 g at 1 m/s and 93% efficiency at particle sizes up to 5 microns, the PB1-AG helps reduce contaminant loading, extend final-filter service life and support reliable turbine performance. Its cleanable synthetic media and stainless-steel frame make it a durable OEM-equivalent replacement for Altair-specified filtration systems.
The PB1-AG is available with three or four individual pockets manufactured from non-shedding, thermally bonded polyester media. The pockets are secured within a robust stainless-steel frame with a 22 mm header, providing stability under high-velocity airflow and challenging environmental conditions.
Standard and non-standard sizes are available, with adjoining clips and factory-fitted seals offered where required for secure installation.

From purchase order to delivery on site. Every PB1–AG is built, checked and shipped by our own team.
Common questions about PB1–AG.
The PB1-AG is an OEM-equivalent pre-pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega. Compatibility should be confirmed using the existing OEM part number, dimensions and operating requirements before ordering.
The PB1-AG is suitable for gas turbine intakes, wind turbine intakes, gas and diesel engines, marine propulsion systems and industrial HVAC filtration units. It can operate in offshore, coastal and onshore environments.
Yes, the PB1-AG is available in standard and non-standard sizes. Adjoining clips and factory-fitted seals can also be supplied to meet specific housing and installation requirements.
The PB1-AG pre-pocket filter is designed for industrial air filtration systems requiring an initial stage of particulate filtration before downstream filters or sensitive equipment.
The PB1-AG can be assessed for suitable gas turbine, engine intake and industrial air handling applications based on the required filter specification, airflow and environmental conditions.
Yes. The PB1-AG can be matched as an OEM-equivalent or replacement-by-specification solution using the existing filter part number, dimensions, pocket configuration, airflow and required performance.
Existing OEM or manufacturer part numbers can be submitted for technical comparison. Specific Parker®, Altair® or other cross-reference numbers should only be included when verified against the relevant product or OEM documentation.
Send the current filter part number, width, height, depth, number of pockets, airflow and filtration requirement. Providing a photograph or technical drawing can further help identify the correct replacement.
The PB1-AG and PB1P8-AG should be selected according to their individual filter construction and application requirements. PB1P8-AG is positioned within Airguard Envirocare's coalescer panel range, so it should not automatically be substituted for a PB1-AG pre-pocket filter without checking the full specification.
The available product information indicates compatibility with Altair System 2, Neptune, and Vega.
PB1-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 PB1-AG is identified as Altair-compatible, Airguard Envirocare positions it as an OEM-equivalent or specification-matched replacement. Confirm exact compatibility 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 PB1-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, PB1-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 specification should be verified for the specific installation.
Yes. Airguard Envirocare offers a 12-month manufacturer's warranty for PB1-AG.
