Overview
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.
The MB advantage is found in the breakthrough technology of our filter bags. Dura-Life™ filter bags and Ultra-Web® pleated bag filters. Dura-Life filter bags provide twice the life over standard 540 g/m² / 16 oz/yd² polyester bags. Our pleated bag options with Ultra-Web SB, provide longer filter life and reduced emissions. Both options can lower the overall cost of operation of the collector.

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 Modular Baghouse has a hopper inlet that was designed with the help of computer airflow analysis to provide maximum performance. When dusty air enters the inlet, it hits a deflector plate at the end of the inlet, which causes heavier particles to drop directly into the hopper. This design reduces the amount of dust that comes in contact with the bags, thus reducing bag abrasion and providing reduced pressure drop and longer bag life.
Dumpster Discharge for Heavy Dust Loading
For applications with heavy dust loading, the MB has an easy to use Dumpster Discharge. This option provides either a 1.5 or 2.3 cubic meter / 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.
Two Breakthrough Filter Options for Your Modular Baghouse
Dura-Life Filter Bags Provide Twice the Life Over Standard 540 g/m2 / 16 oz/yd2 Polyester Bags
Traditional 540 g/m2 / 16 oz/yd2 polyester bags are produced via 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 jets to blend the fibers. This process creates a felt with smaller pores which keeps more dust on the surface of the filter resulting in better pulse cleaning and longer bags life.
Dura-Life Filter Bag Benefits:
- Up to two times longer bag life
- Energy savings due to lower pressure drop
- Reduced replacement bag and maintenance costs due to longer bag life
Pleated Bags with Ultra-Web SB Provide Longer Life and Reduced Emissions
For more than two decades, Donaldson Torit has advanced the proven Ultra-Web fine fiber technology. Ultra-Web provides a very fine, continuous fiber of 0.2 - 0.3 micron in diameter to form a web-like net that traps dust on the surface of the media. Combining Ultra-Web technology with a sturdy spunbond polyester substrate, Ultra-Web SB pleated bag filters provide longer life, reduced downtime and reduced emissions.
Ultra-Web SB Pleated Bag Benefits:
- Reduced collector size and first cost
- Up to two times longer filter life
- Energy savings due to lower pressure drop
- Reduced maintenance and downtime costs
- Reduced emissions

FAQs
Q. What Is a Hydro-Entanglement Process?
A. 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.
Q. How Are Dura-Life Bags Different from Standard Polyester Bags?
A. 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.
