High Efficiency Pocket
Filters
Protect turbines from corrosive contaminants
– to minimise maintenance and extend their lifespan.
Airguard Envirocare manufactures a range of high-efficiency pocket filters designed to protect gas turbines in environments with high levels of sub-micron particulate matter. These solutions support gas turbine air inlet filters and overall gas turbine air inlet filtration, providing a barrier against common contaminants like wet and dry aerosols, drilling mud, grit blasting debris and hydrocarbons.
When used within the air intake system, Airguard Envirocare high-efficiency filters, in conjunction with marine vane separators, reduce salt concentrations, prolonging the turbine's life and reducing maintenance downtime.
The filters can be selected according to operational requirements to provide benefits, including increased turbine output, reduced fuel consumption, and extended filter life cycle. Airguard Envirocare manufactures a range of high-efficiency pocket filters, including HV2-AG, HV3-AG, HVL-AG, HXA-AG, HVX-AG, LHF- AG, T60-AG.
They can be used as gas turbine air inlet pre-filters or as part of the final filtration stage, depending on site conditions and performance requirements.

Other Manufacturer Equivalents
Airguard Envirocare also manufacture high-efficiency pocket filters for other OEM systems.
Our HV2-AG, HV3-AG, HVL-AG, HVX-AG, HXA-AG, LHF-AG and Freudenberg T60-AG filters are compatible with Altair Aquila System, Altair Neptune Systems, Altair Vega Systems and Altair System 2.
These options provide a reliable replacement route where air intake filters are required to match existing designs and performance expectations.
HV2-AG
Offers exceptional protection for turbines in offshore and coastal environments. This filter is specifically designed to perform at high velocities, whether conditions are wet or dry.
HV3-AG
Specifically designed to perform at high velocities in wet and dry conditions, the HV3-AG is ideal for gas turbine ventilation systems, industrial filtration, platform HVAC systems, and marine propulsion.
HVL-AG
Constructed with a two-stage filter pocket design, the HVL-AG combines a high-capacity pre-filter with a high-efficiency needlefelt media, all secured in a durable stainless-steel frame. Optimised for high-velocity performance, it reduces salt ingress, supports improved fuel efficiency, and is suitable for systems such as Altair System 2, Neptune, and Vega.
HVX-AG
The HVX-AG filter offers low-pressure drop, high resistance to salt and humidity, and is cleanable and recyclable. It is suitable for high-velocity airflow and is available in various sizes. It works with multiple pre-filters and is interchangeable with other manufacturer models.
HXA-AG
The HXA-AG filter is built for gas turbine environments, offering high efficiency against salt aerosol and high dust holding capacity. With a two-stage synthetic media design, it performs reliably across wet and dry conditions up to 80°C. It is available in standard or custom sizes and integrates easily with pre-filters and turbine systems.
LHF-AG
The LHF-AG filter delivers reliable turbine protection with high dust-holding capacity and low pressure loss, even in wet and humid environments. It features a secure sealing design to prevent unfiltered air bypass and is available with optional gaskets for added performance.
T60-AG
The T60-AG filter is built for long-term use, requiring fewer replacements and maintaining low pressure loss in both humid and dry conditions. Its high dust capacity and easy-change design reduce downtime and maintenance efforts.
