Donaldson GDS filtration systems clean inlet air for gas turbines and generators in both onshore and offshore applications around the world. Pairs of cartridge filters, mounted horizontally in the filter house, provide maximum filtration efficiency for large turbines with operating airflow of 80,000 to 1.2 million cfm / 2237 to 33557 cu.m/min. Design supports many inlet enhancements such as moisture separators, acoustic hoods, evaporative cooler or chiller coils, and anti-icing systems.

GDS for Large Turbines (over 80,000 cfm).pdf

The GDS filter system has air inlets on two sides, covered by weather hoods with moisture eliminator panels that eliminate 99.5% of droplets larger than 60mm from the incoming airstream. Insect screens are optional and are shown in the photo at left. Banks of filter cartridge pairs provide high-efficiency barrier filtration against dust, pollen, dirt and other airborne particulate. Designed for gas turbines and generators with operating airflow of 9,000 to 79,000 cfm / 255 to 2237 cu.m/min.
