Ultra-Web® cartridge filters consist of a very fine, durable, continuous fiber layer forming a permanent web-like net over a cellulose substrate.
Air Quality for Worker Safety is Our Business
Filters & Parts
Over time, filters become clogged, reducing airflow and allowing fine particulates to bypass filtration. This means higher energy consumption, lowered air quality, process contamination, and potential regulatory noncompliance. Keep your filtration system in peak performance with Process Environments’ complete line of replacement filters and parts.

Cartridge Filters
Ultra-Web® cartridge filters consist of a very fine, durable, continuous fiber layer forming a permanent web-like net over a cellulose substrate. This technology catches submicron dust particles on its surface, which reduces pressure drop and makes pulse cleaning easier. We stock these Donaldson Torit cartridge filters:
- Downflo® Oval
- Downflo® II
- Water, Smoke, and Oil
Ultra-Web® technology extends filter lifespan, saves energy, and achieves MERV 15 and 14 efficiency ratings that meet stringent air quality requirements.
Panel Filters
We provide lightweight, easy-to-handle panel filters for diverse industrial air filtration needs. HEPA filters capture 99.97% of particles as small as 0.3 microns, while 95% DOP filters excel in oil mist applications. Donaldson Torit panel filters are effective for cleanrooms, pharmaceutical manufacturing, and other high-purity environments.
PowerCore® Filters
PowerCore® filter packs can handle high airflow with a 50% to 70% smaller footprint than traditional baghouse and cartridge filters. Proprietary filter media effectively stops submicron particles, and the filters are lightweight and easy to handle and replace. We offer PowerCore® filter packs for general industrial or thermally generated dust.
Bag Filters
Donaldson Torit manufactures a wide range of filters designed for baghouse and other types of dust collectors including
- Fabric Bags
- Pleated Bags
- Helix Tubes
Ultra-Web® SB Pleated Bag Filters
These bag filters use the same proprietary electrospun fiber web as the cartridge filters. They have excellent resistance to damaging materials in challenging industrial environments.
Dura-Life™ Bag Filters
Dura-Life™ filters use a unique hydroentanglement fabrication process that creates a small-pore, uniform material that catches more fine dust particles, resulting in improved surface loading and up to 30% lower emissions.
Competitor Filters
Take advantage of Donaldson Torit’s advanced technology, even if you don’t have a Donaldson filtration system. We carry a complete line of replacement cartridge, panel, and bag filters that fit any type of collection system.
Parts and Accessories
We stock Donaldson Torit parts and accessories that fit most major filtration collectors, including:
- Diaphragm Valves
- Solenoids
- Replacement Kits
We can source replacement components for both current and obsolete dust, fume, and mist collection systems.
