Product catalog summary
Overview
The GDX™ system is a self-cleaning pulse filter system designed to enhance power output in gas turbine systems. It offers high filtration efficiency, reduced maintenance, and extended filter life, making it ideal for remote or hard-to-access locations.
Key Features and Benefits
  • Spider-Web® Filter Media: Proprietary self-cleaning technology that ensures high performance and longevity.
  • Versatile Applications: Suitable for power generation, oil & gas, and industrial uses.
  • Unique Design: Features a cartridge fixation sealing and locking system, and a downflow airflow design for improved pulse-cleaning.
  • Robust Construction: Adaptable to various environments including desert, marine, and arctic conditions.
  • Programmable Control System: Allows pulse cleaning based on time, pressure drop, humidity, or manual initiation.
  • Modular Design: Facilitates shipping, site erection, and space optimization.
  • Global Manufacturing: Donaldson's worldwide presence ensures project-specific manufacturing capabilities.
Operational Mechanism
  • Air Intake: Air enters through inlet hoods, protecting filters from weather elements.
  • Filtration Process: High-efficiency Spider-Web® filter cartridges remove submicron particulates.
  • Pulse Cleaning: A reverse air blast dislodges dust from the filter surface.
  • Dust Evacuation: Dust is moved to a hopper and evacuated after each cleaning cycle.
Enhancement Features
  • Noise Attenuation: Inlet silencing systems and acoustic weather hoods.
  • Power Augmentation: Compatible with evaporative coolers and chiller coil systems.
  • Inlet Heating: Controls bellmouth icing and NOx emissions.
  • Moisture Removal: Inlet treatment systems for moisture elimination.
  • Dust Management: Optional augers, vacuums, and fan systems.
  • Multi-stage Filtration: Additional filtration stages for higher efficiency.
Spider-Web® Technology
Spider-Web technology is central to the GDX system, utilizing Donaldson’s proprietary nanofiber technology for superior turbine protection. The nanofiber web increases filtration efficiency and enhances pulse cleaning effectiveness. The Spider-Web XP variant offers additional protection with nanofiber on both sides of the media substrate.

GDX-2

MAXIMIZING POWER OUTPUT The GDX self-cleaning pulse filter system is designed to exceed the expectations of power plant operators worldwide. It offers high filtration efficiency, lower operating differential pressure and extended filter life. The system's automatic pulse cleaning system ensures that the GDX requires significantly less maintenance than other intake systems - making it the best choice for remote or difficult-to-access locations. Additionally, the pulse-cleaning operation keeps the system pressure drop low, enabling the turbine to run at peak efficiency, maximizing power output....

THE HEART OF THE SYSTEM - SPIDER-WEB® HIGH-EFFICIENCY FILTERS Spider-Web technology is a key component of the GDX system. Donaldson's proprietary nanofiber technology delivers superior turbine protection. Spider-Web nanofiber technology is comprised of a fine, even web of fibers bonded on the upstream side of a filter media substrate (either purely synthetic or a natural/synthetic blend). This web increases filtration efficiency, thus reducing compressor fouling. The enhanced surface loading improves the effectiveness of the pulse cleaning. For added protection, Spider-Web XP carries the nanofiber...
