The LHF-AG is a high-efficiency pocket air filter for gas turbine and heavy-duty industrial air intake systems, using advanced synthetic media for high dust-holding capacity and stable pressure drop in wet and dry conditions. It is an OEM-equivalent replacement for Freudenberg T60 and Parker Hannifin/Altair series pocket filters, engineered for offshore and onshore turbine sites and offered as a lower-cost alternative without compromising build quality or service life.
The LHF-AG pocket filter uses advanced synthetic media designed to maintain low, stable pressure drop as dust builds, including in continuous high-humidity and wet conditions. Edge seals and gaskets around each pocket help prevent unfiltered air bypass at the frame joint, while stainless-steel frame options provide added durability for offshore and coastal gas turbine sites. Standard and non-standard pocket sizes are available to match existing housings without modification.

From purchase order to delivery on site. Every LHF–AG is built, checked and shipped by our own team.
Common questions about LHF–AG.
The LHF-AG is designed for gas turbine air intake and industrial filtration applications where high dust-holding capacity and dependable performance are required. Its rigid pocket construction is designed to maintain filtration performance in wet, dry and humid operating conditions.
The LHF-AG is compatible with Freudenberg T60 and Parker Hannifin / Altair specifications. Listed replacement part numbers include LHF/006220F, LHF/006225F and LHF/006238F, subject to confirmation of the required filter specification and dimensions.
The LHF-AG combines high dust-holding capacity with low pressure loss and a positive sealing arrangement designed to reduce unfiltered air bypass. Its durable stainless steel frame also helps protect against corrosion and degradation in demanding turbine operating environments.
The LHF-AG is a high-efficiency pocket filter designed for industrial and air handling applications requiring effective particulate filtration. Its pocket-filter format provides a large filtration surface within a compact installation space.
Yes. The LHF-AG can be supplied as an OEM-equivalent or replacement-by-specification filter when the original part number, filter dimensions, pocket configuration, airflow and filtration requirements are known.
Yes. Send the existing OEM or manufacturer part number, along with the filter dimensions and technical details. Airguard Envirocare can assess the information to identify a suitable LHF-AG or alternative high-efficiency pocket filter.
Yes. The LHF-AG is suitable for applications requiring a high-efficiency pocket filter, including industrial HVAC and air handling systems where the installed filter specification matches the required performance.
Where a standard size does not match the existing installation, provide the required width, height, depth, pocket quantity and technical specification for replacement matching or custom manufacture.
The choice between LHF-AG and HXA-AG should be based on the existing filter construction, dimensions, required efficiency, airflow and pressure-loss requirements. Sending the current filter part number or specification is the best way to identify the correct replacement.
LHF-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 LHF-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 LHF-AG, including technical datasheets, technical drawings and other relevant information on request.
The LHF-AG manufacturing origin is the United Kingdom.
Depending on the product, order requirements and delivery location, LHF-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 LHF-AG.
