Overview

In many facilities, effective dust collection doesn’t require specialty media—but it still demands reliable filtration, durable materials, and dependable performance. Donaldson’s standard fabric bag filters are designed to help meet every day operational needs, offering strong filtration and dust cake release across a wide variety of general-purpose applications.

These filter bags are built for use in Donaldson and non-Donaldson pulse-jet baghouse dust collectors, and are available in a range of materials and configurations to match your process and performance requirements.

Built for Versatility and Strength

Standard fabric filter bags are ideal for applications that don’t involve high heat or extreme chemical exposure but still require strong filtration media, abrasion resistance, and consistent dust release. Donaldson offers multiple finishing options—like singed or glazed surfaces—to help cleaning efficiency and extend bag usability between changeouts.

What Sets Donaldson’s Fabric Filters Apart?

  • Durable media that can help handle abrasive dust and regular pulsing
  • Surface treatments that support consistent dust cake release
  • Available for a wide range of dust collectors, including non-Donaldson brands
  • Construction options like heat-seamed bags for durability and performance
  • Accessory options such as ground wires, abrasion cuffs, and expansion rings for enhanced support

Media Variations

Polyester Felt – Singed Finish

A versatile, cost-effective option for general dust collection

This 540 g/m² (16 oz/yd²) singed polyester felt is a dependable choice for everyday use in pulse-jet baghouse systems. The singeing process removes surface fuzz and helps create a smooth surface for consistent dust cake release.

Key Features:

  • Strong and abrasion-resistant media
  • Good for applications up to 135°C / 275°F
  • Suitable for a wide range of dry dust types
  • Heat-seamed for durability
  • Available in many sizes and configurations

Polyester Felt – Glazed Finish

For consistent dust cake release in dry applications

The glazing process melts and smooths outer fibers to form a high-sheen finish that supports efficient pulse cleaning. This media shares the same base properties as the singed version but offers enhanced surface smoothness.

Key Features:

  • Glazed outer surface for consistent dust release
  • Strong and chemically resistant
  • Rated for temperatures up to 135°C / 275°F
  • Available with optional accessories for system compatibility

Polypropylene Felt

For chemical exposure and moisture resistance

This 540 g/m² (16 oz/yd²) polypropylene felt is ideal for environments where acids, alkalines, or hydrolysis may be present. It’s also naturally resistant to bacteria and mildew, making it a strong choice for food or chemical applications with moderate temperatures.

Key Features:

  • Excellent chemical resistivity
  • Temperature resistance up to 93°C / 200°F
  • Suitable for wet or corrosive dust environments
  • Compatible with many collector styles

All standard fabric filter bags are available in a wide range of top and bottom configurations, diameters, and lengths. Whether you operate a Donaldson baghouse or a collector from another manufacturer, we can help match the right media and configuration to your application needs.
