Frequently Asked Questions

Common questions about PBR–AG.

The PBR-AG is a gas turbine air intake pre-filter designed to capture larger particles and salt aerosols before they reach downstream high-efficiency filters. It is suitable for gas turbines, wind turbines, gas and diesel engines, marine propulsion and industrial HVAC systems operating in offshore, coastal and onshore environments

Yes. The PBR-AG is an OEM-equivalent pre-pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega. It can be supplied as a replacement for OEM part numbers PBR/000071F, PBR/000107F, PBR/000131F and PBR/001067F, subject to specification and dimensional matching.

The PBR-AG helps protect downstream high-efficiency filters by capturing larger airborne particles and salt aerosols at the first stage of filtration. It offers high dust-holding capacity, 93% efficiency up to 5 microns and reliable performance at temperatures up to 80°C, making it suitable for humid, salt-laden offshore and coastal environments.

The PBR-AG is an industrial pre-pocket filter designed for use as part of a multi-stage air filtration system, where an initial filter helps manage particulate contamination before subsequent filtration stages.

Yes. Depending on the system design, a PBR-AG pre-filter can form part of a staged filtration arrangement before downstream coalescer or higher-efficiency filters. The final arrangement should follow the equipment and application requirements.

Yes. Airguard Envirocare can assess the PBR-AG as an OEM-equivalent or replacement-by-specification filter when supplied with the existing part number, dimensions, airflow and filtration requirements.

A Parker® or Altair® cross-reference should only be published when verified against the relevant product documentation. If you have an existing OEM part number, it can be submitted for compatibility assessment and replacement matching.

For non-standard installations, provide the existing filter dimensions, technical drawing or sample, together with the required airflow and performance specification, for replacement matching.

Both PBR-AG and PB1-AG are part of the Airguard Envirocare filtration range, but they should not be treated as automatically interchangeable. The correct filter should match the installed system, dimensions, airflow and required filtration performance.

PBR-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 PBR-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 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 PBR-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, PBR-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 warranty for PBR-AG.
