Donaldson Torit Extends Proven Ultra-Web Technology to Deliver MERV 15 Rated Cartridge Filter

Share Article

New higher efficiency cartridge filter delivers longer filter life, cleaner air and greater energy savings.

Donaldson® Torit® announces its Ultra-Web® nanofiber technology line now includes an even higher efficiency cartridge filter that delivers longer filter life, cleaner air and greater energy savings. Ultra-Web SB, certified by independent lab tests at MERV 15 efficiency, is the latest extension of this dust collection technology that is backed by 80 issued and pending patents worldwide and has performed 25 years in the field.

Ultra-Web SB filters ship in 24 hours and are available as replacement filters for Donaldson Torit cartridge dust collectors as well as all other popular dust collectors. Ultra-Web technology also improves lives, extending beyond dust collection to use in medical research, M1 Abrams tanks and more.

Ultra-Web SB with MERV 15 efficiency is a tougher filter ideally suited for applications that face challenges from agglomerative dust in industries such as chemical, pharmaceutical, cosmetic, textile, grain, woodworking, metalworking and others. This filter media combines the excellent surface-loading and dust release capabilities of high efficiency Ultra-Web technology with a strong spunbond polyester substrate for enhanced durability, moisture and chemical tolerance when compared to typical spunbond or meltblown filter media. The spunbond substrate is also made with a unique resin-free process that allows Ultra-Web SB to perform in challenging conditions where higher temperature, chemicals and moisture could weaken or destroy the resin system within standard substrate media.

Ultra-Web SB cartridge filters also feature wide pleat spacing which allows thorough pulse cleaning of fine and fibrous particulate including ceramics, cotton, fiberglass, grains, shotblast, grinding, polishing and dust from powder coating.

To meet a wide variety of application needs, Donaldson Torit provides a full Ultra-Web line that filters submicron dust particles (0.3 micron and larger) with MERV 13, 14 or 15 efficiency ratings. Donaldson Torit has optimized its MERV 13 rated Ultra-Web technology through the years to provide the longest filter life and lower stabilized pressure drop while requiring less energy. Cartridge filters with higher MERV ratings often have shorter filter life.

Donaldson Torit designs, manufactures and markets in-plant air filtration and pollution control systems, replacement filters and products that help eliminate dangerous dust, fume and mist contaminants from the workplace. Donaldson Torit is part of the Donaldson Company, a leading worldwide manufacturer of filtration systems.
