Cartridge Filters

Whatever brand cartridge-style filter house you have, we have a filter for you. If you didn't get Donaldson filters originally, try upgrading to Donaldson Spider-Web®, our nanofibre media technology, for higher efficiency filtration.

Spider-Web® Technology

Proven and proprietary Spider-Web® technology delivers longer filter life, cleaner air and greater cost savings than other types of filter media. Made with an electrospinning process that produces a very fine, continuous, resilient fibre 0.2-0.3 micron in diameter, Spider-Web forms a permanent nanofibre web with very fine interfibre spaces that trap dust on the surface of the media.

  • Superior media, capturing submicron dust particles
  • Longer filter life, better pulse cleaning, surface loading technology
  • Lower pressure drop, optimal pulse cleaning, maximum turbine efficiency
  • Filtration efficiencies to meet specific application needs

A filter must be rated at least a MERV 13 on the ASHRAE 20-point scale to effectively filter submicron dust particles. Donaldson® has perfected our standard MERV 13-rated Spider-Web filters, optimising filtration and turbine efficiency without sacrificing filter life or increasing pressure drop.

For applications that require even  higher efficiency, there’s a Spider-Web  filter to meet your needs.

GDX & GDS Filter Pairs

In the Donaldson GDX Air Inlet Self-Cleaning (pulsed) and GDS (static) Filtration Systems, one conical and one cylindrical filter are paired and mounted horizontally to provide superior turbine protection.

Features

  • Many high performance choices, including our exclusive high performance Spider-Web and Spider-WebXP nanofiber media.


Sturdy Construction

  • Pleats: To maintain maximum filtering surface: pleats are held in place with hot melt spiral beading inside and outside, our patented Pleatloc™ technique prevents media bunching.
  • Liners & Endcaps: Galvanized metal or stainless steel
  • Gasket: Seamless urethane
