Overview

 

Managing air quality in industrial environments is essential to the efficiency and productivity of your operation. At Donaldson, we understand the challenges you face—filter changeouts, high pressure drops, equipment wear, and regulatory compliance. That’s why we offer a complete range of Pleated Bag Filters designed to help extend filter life, reduce maintenance, and keep your operation running efficiently.

Whether you're running Donaldson or non-Donaldson equipment, our pleated bag filters offer a reliable solution to optimize your baghouse performance—all with the support of our global service and engineering expertise.

A Smarter Filtration Solution for Baghouses

Pleated bag filters are engineered to help resolve common issues found in traditional baghouse operations. The pleated design increases filtration area without requiring modifications to your existing system, while also allowing for easy handling and changeout.

How Our Filters Help:

  • Limited Filter Area: Pleated design provides 2–3 times the filtration surface area in the same footprint
  • High Pressure Drop: Lower air-to-cloth ratio reduces pressure drop and energy demand
  • Abrasion Concerns: Shorter filter length creates a larger drop-out zone, reducing filter wear
  • Stack Emissions: Advanced fine-fiber media captures submicron particles
  • Frequent Changeouts: Durable media and surface-loading properties extend filter life

What Sets Donaldson Apart

Our pleated bag filters combine innovative engineering, application-specific media, and a customer-first design approach to deliver an effective, hassle-free filtration experience.

Benefits at a Glance:

  • One pleated bag replaces one traditional bag and cage
  • Increased effective filtration area
  • Fast, easy installation and removal
  • Less downtime and airbone dust.
  • Low compressed air usage and maintenance
  • Available for Donaldson and non-Donaldson collectors

Key Product Features

  • iSeal Gasket: Soft EPDM gasket ensures a secure seal
  • High Flow Nozzle: Integrated with the venturi for top load collectors, it provides direct airflow, improves pulse energy and decreased pressure drop over the life of the filter.
  • One-Piece Molded Design: Reduces leakage potential at the tube sheet

Media Options for Every Application

Donaldson offers a wide range of media types to match the specific needs of your process—from standard environments to high-temperature or chemically challenging applications.

Ultra-Web® SB Filter Media

A fine-fiber web (0.2–0.3 microns) on a spunbond substrate traps dust at the surface, helping extend filter life and maintain airflow performance.

Specialty Media Options

  • PTFE (Torit-Tex®) Media: Ideal for moist or chemically harsh environments
  • Aramid: Designed for high-temperature dry processes (up to 191° C / 375° F)
  • PPS: Helps withstand chemical exposure and elevated temperatures
  • Conductive Grid: Suitable for electrostatic environments

Standard Efficiency Media

  • Spunbond Media: Durable spunbond construction increases filtration area while providing solid performance for a wide range of dry applications.
