Mueller - Model GTAF -Gas Turbine Inlet Air Filter
The Mueller Model GTAF Gas Turbine Inlet Air Filter is a highly effective and versatile inlet air filtration system that efficiently removes solid particulates, moisture and salts. Extensively field proven in a wide range of conditions in both offshore and land-based applications, the GTAF is a durable, compact, low-pressure drop, cost effective product. The GTAF has been a workhorse on rotating machinery from 1,000 to 12,000 hp. Because it holds a variety of 24" x 24" filter and prefilter combinations, the GTAF enables ideal filter selection to accommodate a wide range of efficiency requirements and air flow conditions.
The filtering efficiency of the extended surface area cartridge filter with pre-filter is 99% by weight arrestance, based on AC fine test dust, resulting in the removal of 99.2% of all dust particles 3 microns and larger in the air stream. The typical configuration of the GTAF system consists of an inlet air filter house with filter maintenance area, clean air plenum, rubber isolation joint, implosion door, duct with inlet trash screen and 90°-degree elbow, structural steel and ladders with platforms. The filter house design provides for two banks of filter elements 4’ wide and 5’ high.
