The PFA-AG is a high-efficiency pre-pocket filter designed for gas turbine intake systems, capturing coarse and medium particles, salt aerosols and moisture before they reach downstream high-efficiency filters. It is built for high-velocity airflow in wet and dry conditions and provides an OEM-equivalent /Altair® replacement for offshore, coastal and onshore sites, with non-shedding polyester media and a stainless-steel frame.
Construction
The four pockets use non-shedding polyester media in a strong stainless-steel frame, helping prevent fibre release and maintain shape at high air velocities. The synthetic media handles wet, humid, sea spray and dry conditions, while its cleanable design helps reduce replacement costs.

Effective and well made
Does the job well at a fair price. Would like a couple more size options, but the performance is excellent.

Priya Barker
Exactly to spec, fast turnaround
Matched our OEM specification perfectly and was delivered within 24 hours. Excellent airflow and build quality.
Nathan Mercer
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 Adeyemi
Would order again
Noticeable improvement in air quality after fitting these. Sturdy frame and accurate dimensions — no complaints.
Michael Harrison
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.
Leah Martins
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.
