Compact Filters for Gas Turbines

in EN 779 filter classes F7, F8 and F9 and ISO 16890 filter classes ISO ePM1, ISO ePM2,5, ISO ePM10

Compact filters owe their name to their compact, space-saving construction. They provide maximum media area within minimum volume, offering an optimum combination of high filtration efficiency and low pressure drop. As a result, compact filters attain long service life even when used with high volume flow rates and high inlet particulate concentrations.

EMW® has a proven track record spanning more than 30 years as a manufacturer and supplier of minipleat compact filters for gas turbine inlet air filtration. Whatever your gas turbine, its operating mode site air conditions and maintenance intervals, we can provide the best air filter for the job at hand.

Application Fields

High Efficiency + Rugged Construction
= Reliable Power Plant Operation

Our GT compact filters offer up to 38 m² media area in a single space-saving filter unit. A cast airtight seam joins the water-repellent media to the aerodynamically optimized plastic frame. A fully synthetic nonwoven fabric mat on the outlet side enhances pleat strength, ensuring secure operation even with pressure drops in excess of 5000 Pa and under other heavy-duty conditions.

Can be stopped and rotated!


Highly Efficient Filter Media

For efficient particulate removal even under heavy-duty operating conditions.

XXL Media Area

Innovative minipleat technology provides maximum filter media area in the smallest of spaces.

Heavy-Duty Strength

EMW® minipleat compact filters for gas turbine applications are equipped with a pleat reinforcing mat on their outlet side. This reinforcement system provides superb toughness and other advantages over conventional metal or plastic reinforcing grids. The result: heavy-duty strength and outstanding dependability even under extreme conditions such as pressure drops greater than 5000 Pa.

Aerodynamically Optimized Frame

EMW® GT compact filters incorporate a specially designed plastic frame which minimizes turbulent air flow in gas turbine inlet air filtration. GT compact filters provide further benefits as well: they are easy to install and fully incinerable for simple disposal after use.

Advanced Design for Superb Airtightness

The filter media is joined to the frame by an airtight full-perimeter joint. The joined module is finished with a continuous foamed-in-place seal applied on the inlet or outlet side as desired.

All data given are based on test results determined according to EN 779 or ISO 16890. The data are average values subject to tolerances due to normal production fluctuations. The figures are only suitable for comparison with those of other products tested according to the same standard. Dust holding capacity according EN 779 is measured till a final pressure drop of 450 Pa, whereas according ISO 16890 the dust holding capacity is measured till 300 Pa. If higher final pressure drop levels are suitable, the dust holding capacity will be accordingly higher.
