Donaldson static (rather than self-cleaning) air filtration systems are most often chosen to protect inlet air on turbines and generators in urban, industrial, offshore, marine, and coastal environments.

GDS for Turbines with Airflow above 80,000 cfm
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 Turbines with Airflow below 80,000 cfm
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 cm/min.

GTM for Marine/Offshore Applications
Our 4-stage system very effectively removes dirt and salt particulate from the airstream, AND virtually eliminates water carry-over –- so the turbine on your FPSO, oil platform, or coastal location is well protected despite the weather. Modular configurations allow sizing for any turbine, small or large. Uses pocket-style filters.

GTR System with PowerCore Filters
Designed for low maintenance, GTR employs our patented PowerCore filter media technology. Because filters made of PowerCore handle more airflow than conventional pleated-paper filters, the GTR can be much smaller -- as much as 2/3 smaller! -- than conventional inlet filtration systems. Robust PowerCore provides high-capacity particulate loading, resulting in long filter life at a sustained low pressure drop.
