Airguard Envirocare V99XS-GT-AG is an OEM-equivalent coalescer panel filter designed for demanding gas turbine, marine, offshore wind and industrial air intake applications. It provides a reliable replacement solution for compatible Altair® and other OEM air intake systems.

The V99XS-GT-AG was developed for gas turbine air intake filtration, where protection from airborne dust and liquid water droplets is essential for reliable equipment operation.
Its coalescing design helps remove water droplets while also capturing particulate contamination. This makes the filter suitable for environments where moisture, salt-laden air and airborne contaminants can affect turbine and engine performance.
The V99XS-GT-AG is compatible with a range of OEM systems, including Altair® System 2, Neptune, Vega and Aquila, as well as compatible Airfil GT2, Veotec CP2, Wozair CP2 and Sterling Thermal filter installations.
Airguard Envirocare manufactures OEM-equivalent filtration solutions to match the required form, fit and performance specification, with standard and non-standard sizes available for replacement and bespoke applications.
The V99XS-GT-AG uses a high-efficiency polyester filter mat positioned between two layers of stainless-steel wire mesh. The filter media is pleated into a corrugated V-profile to increase the effective filtration area and improve structural rigidity.
The pleated filter core is retained inside a robust stainless-steel frame available in 22 mm or 50 mm depths. Standard and non-standard sizes can be supplied, together with adjoining clips and seals for installation into compatible air intake housings.
