Donaldson Torit Modular Baghouse (MB) Dust Collectors

​The Donaldson® Torit® Modular Baghouse (MB) dust collectors deliver reliable, efficient, continuous-duty, pulse-jet operation & easy maintenance.​​​​

Modular Baghouse Dust Collectors

290_Modular_Baghouse_CollectorsCompact, Modular Design

The MB advantage is found in the breakthrough technology of Dura-Life™ bag filters. Dura-Life bags offer longer bag life and reduced emissions. The MB provides reliable service with easy maintenance. Computer designed inlets and deflector plates, coupled with maximized bag spacing, result in optimal airflow with minimal abrasion. Advanced valves, providing 50% more cleaning air, result in a more efficient operation. Over the life of the collector, no other baghouse can provide this much value.

Baghouse Operations That Work

The Modular Baghouse collector comes in two models: the MBT allows walk-on, top access to the bags (clean-air side) of the collector. This configuration is ideal for indoor or tight budget applications. The MBW offers a walk-in clean-air plenum, so bags can be replaced in any kind of outdoor weather.

The MB has two inlet configurations; the most common configuration allows the dirty-air to enter through the hopper inlet located under the bag filters. The dirty air hits a deflector at the end of the inlet, which causes heavy particulate to fall directly into the hopper. This reduces the amount of dust that comes in contact with the bags resulting in longer bag life and lower pressure drop. For applications with light and fibrous dust, a high body inlet is available that reduces upward air velocities allowing the dust to properly fall into the hopper after the bags have been pulsed.

Engineered For Reliable Performance

Modular Baghouses are a reflection of Donaldson Torit’s commitment to technical research and development. Sophisticated FLUENT®* computer airflow analysis has been used to assure the Modular Baghouse provides a uniform airflow resulting in reduced bag abrasion, longer bag life and lower maintenance costs.

Dumpster Discharge For Heavy Dust Loading

ModularDumpsterDischargeFor applications with heavy dust loading, the MB has an easy to use Dumpster Discharge. This option provides either a two or three cubic yard self-dumping dumpster that can be hauled away with the use of a forklift. The dumpster comes with a lid that seals the system so that no rotary valve is required. The lid is lifted off of the dumpster via a mechanical lift, which is included with the package.

Dura-Life Technology - A Breakthrough For Bag Users

Standard in all Donaldson Torit MB Baghouse Collectors

Traditional 16 oz. polyester bags are produced with a needling process that creates larger pores where dust can embed into the fabric, inhibiting cleaning and reducing bag life. Dura-Life bags are engineered with a unique hydroentanglement process that uses water to blend the fibers. This process provides a more uniform material with smaller pores, better surface loading, and better cleaning. These advantages provide twice the operating life before bags need to be replaced due to pressure drop. Longer life from Dura-Life bags lowers maintenance and operating costs and raises baghouse dust collection to a whole new level.

What is a hydro-entanglement process?

Instead of a mechanical process using needles to entangle and compress polyester fibers into a felt material, the hydro-entanglement process uses jets of water to entable and compree the polyester fibers into felt. The process creates a material that is more uniform and provides better filtration.

How are Dura-Life bags different from standard polyester bags?

Dura-Life bags are made from polyester material that is created through a hydro-entanglement process instead of a needle punch process. The hydro-entanglement process creates a more consistent and uniform filter material. The material is comparable in thickness to standard polyester, but weighs about 1/3 less. The fibers are smaller and the hydro-entanglement process creates a loftier and lighter weight fabric that filters more effectively.
