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.
Airguard Envirocare HXA-AG is an OEM-equivalent high-efficiency pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega, providing reliable filtration for gas turbine intake applications.


The HXA-AG High-Efficiency Pocket Filter is designed for gas turbine air-intake systems, providing high-efficiency filtration in offshore and coastal environments. It is built to handle high air velocities in both wet and dry conditions, helping protect turbines from challenging intake-air conditions. As an OEM-equivalent replacement for Altair-specified systems, the HXA-AG offers high dust-holding capacity and reliable build quality for demanding power-generation applications.
The HXA-AG has four filter pockets with a two-stage construction: a high-loft nonwoven mat captures coarser dust, while 100% polypropylene lofted media provides high-efficiency filtration. Needlefelt separators keep the pockets evenly spaced under airflow, helping maintain lower resistance and higher dust-holding capacity. The pockets are held in a stainless-steel frame with a 22 mm header, with standard and non-standard sizes available, plus adjoining clips and factory-fitted seals for multi-panel installations.

Holds up well under load and keeps our energy costs down. Very happy with the performance across the plant.
Matched our OEM specification perfectly and was delivered within 24 hours. Excellent airflow and build quality.
Dust holding capacity is noticeably better than what we were using, so we're getting longer intervals between changes.
Does the job well at a fair price. Would like a couple more size options, but the performance is excellent.
Good build and consistent efficiency. Easy to install and the technical team helped us pick the right grade.
We've switched our units over to these and the efficiency is consistent with a noticeably longer service life than our previous supplier.
We order these regularly and the quality doesn't drift — same media, same fit, same performance every time.
Noticeable improvement in air quality after fitting these. Sturdy frame and accurate dimensions — no complaints.
Meets our stringent air quality targets and the support from Airguard helping us specify was first class. Highly recommend.
