Frequently Asked Questions

Q.What is so unique about the Zero-Turn Pulse Cleaning System and how does it benefit me?

A.As the name implies, the Zero-Turn Pulse Cleaning System delivers maximum cleaning energy in straight-line paths through the media and easily pulses the dust out of the fluted channels. No old-style blowpipe delivery systems, no airflow bends and turns through the media—all the cleaning energy goes straight through the fluted channels. As a result, the filter packs clean better, recover more easily, and filter life is extended.

Filter Bags

Q.The material in Dura-Life bags is only 10.5 ounce vs. the 16 ounces found in polyester. Are they as durable as standard polyester bags?

A.Absolutely, Dura-Life bags are as durable as any standard polyester bad on the market today. The Dura-Life product is actually comparable in thickness to standard polyester, but is made from smaller denier fiber through the hydro-entanglement process that creates a loftier fabric. As part of the battery of tests that we ran on the Dura-Life material to qualify the material prior to release, we ran a series of abrasion tests. The Dura-Life material passed these abrasion tests with flying colors.

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.

Mist Collectors

Q.What are the advantages of Synteq XP Media?

A.Proprietary Synteq XP Media is engineered with a blend of small and large fibers with a resin-free bonding system. The result is superior performance and longer filter life in the most challenging applications.

Q.What size are mist droplets/particles?

A.Mist can generally be defined as a liquid droplet 20 microns in diameter or smaller. Oil-based fluids typically produce mist droplets that range from 0.5 microns to 10 microns. A smoke droplet is typically smaller, from 0.07 microns to 1 micron, and is a solid or liquid aerosol.

Q.What determines the performance of a mist collector?

A.A mist collector can be characterized by pressure drop, efficiency, and flow rate. Pressure drops affects the energy required to pull the airflow through the system. The efficiency of the system determines how clean the air will be as it leaves the collector and flow rate determines how much air will be cleaned.

Torit PowerCore Collectors

Q.Is the PowerCore filter a bag or a cartridge?

A.The PowerCore filter is neither a bag nor a cartridge. It’s a filter pack with a handle. We’ve configured the media into a corrugated flute structure, which not only makes the pack rigid and sturdy, but allows more media to be used effectively in a smaller volume. The media is then rolled into an “ob-round” shape that is only 7" deep by 22" long. The PowerCore filter pack, in conjunction with the PowerCore collector, has been designed to replace conventional baghouses with fabric or pleated filter bags. You’ll be amazed at how easy it is to change out the PowerCore filter packs. They can be removed and replaced in just minutes, without using tools—and without a confined space permit.

Q.Why are Torit PowerCore TG dust collectors so much smaller than traditional cartridge collectors?

A.The difference is compact PowerCore filter packs in combination with a very unique collector design. One compact, offset-stack TG filter pack replaces up to three traditional filter cartridges. The PowerCore technology enables us to package more effective filtration media area into smaller spaces because of its unique, corrugated configuration method. Pairing the compact PowerCore technology with our Donaldson-developed, proprietary Ultra-Web® media technology allows the dust collectors to shrink in size. And that is not all. The dust collector itself is designed to be smaller and smarter. By engineering the airflow patterns inside the collector, and by adding the new state-of-the-art Zero-Turn Power Pulse Cleaning System, we have been successful in reducing the overall housing volume while maintaining excellent filtration performance.

Q.What kind of dust can Torit PowerCore TG handle?

A.So far, we’ve tested and approved Torit PowerCore TG for all thermally generated dusts and some metalworking dust, including: * Laser Cutting * Plasma Cutting * Welding * Thermal Spray We continue to test and develop Torit PowerCore solutions for other dust challenges. Donaldson Torit will always recommend the best filtration solution for the specific application, whether it’s a cartridge, baghouse, or Torit PowerCore.

Q.Is the PowerCore TG filter pack a bag or a cartridge?

A.The PowerCore TG filter pack is neither a bag nor a cartridge. It’s a rectangular filter pack in a lightweight metal casing with an easy-grip handle. The media is configured into a corrugated off-set stack flute structure, which not only makes the pack rigid and sturdy, but allows more media to be used effectively in a smaller space. The metal casing adds rigidity needed in metalworking environments. You’ll be amazed at how easy it is to change out the PowerCore TG filter packs. It takes only one person to remove and replace the filter packs in just a couple of minutes, without using tools and without any loose parts to handle.

Q.What kind of filter media is used in PowerCore TG filter packs?

A.Our best: our Donaldson-developed and proprietary Ultra-Web® media. It’s made of two layers—a sturdy substrate bonded with a thin layer of nanofiber—that capture both small and large particulate—resulting in a very high performance media. The ASHRAE 52.2-1999 test standard proves it. Standard PowerCore TG filter packs have a Minimum Efficiency Reporting Value (MERV) of 13.

Q.Are Torit PowerCore TG collectors and PowerCore TG filter packs available from other manufacturers?

A.No. Torit PowerCore TG dust collectors and PowerCore TG filter packs are only available from Donaldson Torit.

Q.How can the Torit PowerCore CP Series collectors be so much smaller than a traditional baghouse?

A.There are two reasons the Torit PowerCore CP Series collectors are smaller: the filter packs and the collector design. One 7" PowerCore filter pack replaces six traditional 8' fabric filter bags. We are able to include a large amount of filter media area in the 7" space because of the unique corrugated configuration method. With shorter filter packs, the size of the collector can be reduced. The collector is designed to be smaller and smarter. By engineering the airflow patterns inside the collector, we have been successful in reducing the amount of space required while maintaining excellent filtration performance.

Q.Does Torit PowerCore improve traditional baghouse filtration?

A.Yes. The PowerCore CP Series collector design and engineered airflow work to prevent a common baghouse problem—bridging. The possibility of dust bridging between the filter packs is eliminated in Torit PowerCore. By designing the filter pack and the collector together, Donaldson Torit has developed an optimized solution for dust collection where baghouses are typically applied.

Q.Can dust bridging become a problem with Torit PowerCore?

A. No. There is no chance of bridging between PowerCore filter packs—and therefore no plugging due to bridging—in a Torit PowerCore collector. Here’s why: * Bridging happens in baghouses because the pulse-cleaning knocks accumulated dust down the length of the filter, and often it accumulates in the lower interstitial spaces. On particulate that tends to stick to itself or nest, the accumulation builds, eventually into a bridge. Torit PowerCore is engineered with computer-modeled fluid flow analysis to manage the incoming dirty air and the velocities directed into the filter pack, avoiding interstitial problems. And, the PowerCore filter pack is only 7" deep, so there’s virtually no opportunity for a dust bridge to develop. * Donaldson Torit’s new Compact Pulse Cleaning System is a proprietary, computer-modeled pulse-cleaning technology designed to match the “ob-round” shape of the PowerCore filter pack. The pulse pattern covers the entire media pack and pulses the dust out of the fluted channels. There is no possibility of bridging.

Q.What kind of dust can Torit PowerCore CP handle?

A.So far, we’ve tested and approved Torit PowerCore for many industries where baghouses are typically applied, including: * Cement & Gypsum * Food Products * Mining & Quarry * Grain – Milling & Processing * Paper & Packaging * Plastics * Glass * Textiles * Rubber * Wood – Lumber, Furniture & Millwork (including very fine wood flour) We continue to test and develop Torit PowerCore solutions for other dust challenges. Donaldson Torit will always recommend the best filtration solution for the specific application, whether it’s a cartridge, baghouse, or Torit PowerCore.

Q.What kind of filter media is used in PowerCore filter packs?

A.Our best: our Donaldson-developed and proprietary Ultra-Web® media. It’s made of two layers—a sturdy substrate bonded with a thin layer of nanofibers—that capture both small and large particulate—resulting in a very high performance media. The EPA PM2.5 testing proves it. PowerCore filter packs have 78% FEWER emissions than traditional polyester filter bags.

Q.Can I retrofit my current collector with PowerCore filter packs?

A.Not at this time. Torit PowerCore uses an advanced filtration technology. The filter packs, tubesheet, pulse-cleaning system and engineered airflow of the collector have been optimized as an integrated system. Retrofitting an existing collector is not advised.

Q.Are Torit PowerCore and PowerCore filter packs available from other manufacturers?

A.No. Torit PowerCore and PowerCore filter packs are only available from Donaldson Torit.

Q.Why do PowerCore TG filter packs recover better than traditional filter cartridges?

A.If you experience those job shifts of cutting typical 10 gauge sheet metal today and 1/4" or thicker plate steel tomorrow, the better recovery feature means a lot to you. PowerCore TG filter packs can handle the shift in dust loading better than any traditional filter cartridge because they can collect more dust and they are cleaned by the channeled pulse energy of the Zero-Turn Pulse Cleaning System. Therefore, PowerCore TG filter packs recover more easily than traditional filter cartridges from dramatic spikes in pressure drop during pulse cleaning. The result is longer filter life.

Q.Can I retrofit my current collector with PowerCore TG filter packs?

A.Not at this time. Torit PowerCore uses an advanced filtration technology. The filter packs, tubesheet, the new state-of-the-art Zero-Turn Pulse Cleaning System and engineered airflow of the collector have been optimized as an integrated system. Retrofitting an existing collector is not advised.
