Self-Cleaning Filter Systems

Donaldson self-cleaning systems are designed to help turbines & generators operate everywhere – in dusty deserts, urban/factory areas, on the coast, in the frosty north. Because they are self-cleaning, they require little maintenance between filter change-outs.

GDX for Large Turbines
The OEMs’ number one choice, the Donaldson GDX™ has become the industry standard for pulse-cleaned inlet air filtration systems over the last decade and a half. Its banks of filter cartridge pairs (mounted horizontally) are made with high-efficiency Spider-Web filter media technology. GDX provides convenience and high filtration efficiency for turbines with operating airflow of 80,000 to 1.2 million cfm / 2237 to 33557 cu.m/min. This Design supports many inlet enhancements such as moisture separators, acoustic hoods, evaporative cooler or chiller coils, and anti-icing systems.
GDX System Description

GDX for Smaller Turbines
Sized for turbines requiring airflow less than 79,000 cfm/ 2237 m3/min, this GDX design has all the same convenience and high-performance characteristics of its larger brother, but fewer filter cartridges.

The Donaldson TTD™ system is the original pulse cleaning air filter system for gas turbine and generator ventilation applications. Filter cartridges are mounted vertically. Available with one level of filter elements for airflow up to 79,000 cfm/ 2237 m3/min, or with several filter levels to accommodate larger airflow.
