HV3-AG was engineered for gas turbine air intake systems that need reliable protection in offshore and coastal settings. Salt-laden air and moisture can quickly corrode turbine internals if left unfiltered. HV3-AG stops this by combining high fine-particle efficiency with low pressure drop, so the turbine keeps its output and fuel efficiency over long duty cycles.
The filter is optimised for high face velocities, in both wet and dry conditions. As an OEM-equivalent replacement filter, HV3-AG matches the fit and function of the original Altair part, so it drops into existing housings without modification.
Construction
HV3-AG pockets are manufactured from nonwoven needlefelt polyester filter media, chosen for its high efficiency characteristics and non-shedding bonded structure. The filter is supplied with 3 or 4 pockets depending on the housing configuration and is held in a stainless-steel frame with a 22 mm header. Full stainless-steel construction is available for maximum corrosion resistance, along with factory-fitted seals and adjoining clips for bank installations.

Solid quality
Good build and consistent efficiency. Easy to install and the technical team helped us pick the right grade.
Nathan Grant
Great filtration and good value for money. Delivery was prompt and the fit was accurate for our housings.
Grace Bennett
Cut our change-out frequency
Dust holding capacity is noticeably better than what we were using, so we're getting longer intervals between changes.
Andrew Fletcher
Straightforward specification
Sent over our old filter details and got a like-for-like match back the same day. Fitted first time with no modifications needed.
Leah Blake
Top quality and great support
Meets our stringent air quality targets and the support from Airguard helping us specify was first class. Highly recommend.
Ryan Hughes
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.
Hannah Kowalski
Good communication on lead times
Kept us updated from order through to dispatch. The filters themselves have performed exactly as described.
