Product Overview
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.
Construction
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.

Consistent between batches
We order these regularly and the quality doesn't drift — same media, same fit, same performance every time.
Hannah Nair
Would order again
Noticeable improvement in air quality after fitting these. Sturdy frame and accurate dimensions — no complaints.
David Dawson
Low pressure drop, high dust holding
Holds up well under load and keeps our energy costs down. Very happy with the performance across the plant.
Isla Bennett
Reliable performance
We've switched our units over to these and the efficiency is consistent with a noticeably longer service life than our previous supplier.
Nathan Sinclair
Cut our change-out frequency
Dust holding capacity is noticeably better than what we were using, so we're getting longer intervals between changes.
Grace Timms
Effective and well made
Does the job well at a fair price. Would like a couple more size options, but the performance is excellent.
Andrew Hughes

Good build and consistent efficiency. Easy to install and the technical team helped us pick the right grade.
