How Do Industrial Dust Collectors Work?

Built tough, industrial-sized dust collectors are the workhorses of the industry. 

Standing as tall as 50 feet in some cases, industrial dust collection systems by Lapp Millwright are designed for robust, long-term use in high-dirt settings like manufacturing and grain or feed handling. 

These dust collectors are not for light-duty work, like your hobby woodworking shop, and often get used in the most dirty manufacturing settings – also where they’re most important to keeping products impeccable and team members healthy! 

Powerful and effective, industrial dust collection systems are deployed in industries that handle the dustiest and nastiest of the dirty: grain handling, seed handling, rubber production, silica, feed manufacturing, wood shops, aggregate handling, and more.

Anywhere you’re dealing with particulate, smoke, or dust, Lapp Millwright’s industrial dust collection systems can help you create a safer, healthier, more efficient, and cleaner working environment for your team.

How Industrial Dust Collection Systems By Lapp Work

Lapp Millwright has made dust collection our business since 2001. With both off-the-shelf and custom systems, easy-to-clean filters, and time-saving features refined over decades of customer feedback and real-world use, our industrial dust collectors are built to breathe easy.

Most dust collectors that we build or provide use a series of hoses and inlets attached to machinery to pull dust and debris off the manufacturing floor at the site of its creation, like a small vacuum hose next to a chop saw, or an inlet near a grinder. These tubes pull the particulate to a central dust filtration system, generally located outside the building, that includes a vortex chamber and traditional filter baghouse, where small and large dust particles either fall out the bottom into a large hopper or are trapped in one of many central filter bags, the heart of the dust filter system. 

In the case of ambient dust filters, which work to pull finer particulate out of the air rather than right at the site of the dirt, your industrial dust collection system in the building might look more like a large HVAC system.

Features of Industrial Dust Collectors

Our dust collection and filter systems rely on a few select steps to effectively filter air:


      1. A vortex chamber

      1. A baghouse with filters

      1. Proprietary self-cleaning devices

      1. A blower powering the entire system

    Lapp Millwright provides some of the most vetted and effective dust filtration systems around. 

    It begins with our unique vortex chambers, where air and dirt first enter the filtration element. Air and dirt from the manufacturing floor enter this cylindrical chamber at a high rate of speed, at which point pressure immediately drops. Large debris, large dirt, and bigger particulates almost immediately fall out of the air to the bottom of the vortex chamber. This critical step removes a substantial amount of the heavier and larger debris that normally clogs filter bags, helping to save you time and expense with less filter cleaning and less frequent filter replacements. Our systems can often extend filter life by 2X compared to traditional filter systems with no vortex chamber. Bulk material then falls out of a dedicated air lock at the bottom of the bag house. 

    The remaining finer particulates then travel upward through the vortex chamber and into the industrial bag house (IBH), where dozens of long, tubular filter bags remove fine dust and particles from the air. 

    Compared to traditional industrial dust filters, the inclusion of a dedicated vortex chamber dramatically reduces filter replacement, extends filter life, and reduces ongoing maintenance issues. 

    Our industrial collectors also come standard with explosion relief panels and a walk-thru entry door in the clean air compartment for maintenance and filter changes. Filter bags come standard with snap tops and disc bottoms for very easy filter change-outs. 

    Self-Cleaning Industrial Dust Filters

    Finally, our dust collectors feature two unique and proprietary self-cleaning methods to reduce cleaning frequency and save you money on filter replacements: reverse air blowers and medium pressure cleaning systems. 

    Both systems live above your filters and work by creating reverse air through the filters to knock dirt loose and extend filter life. The advantage of the reverse air blower is that it requires no solenoids or diaphragms, no drive chains or sprockets to maintain, and no need for compressed air. Our complete bag house can even stay online while cleaning is in process. 

    Our medium pressure cleaning system uses its own air pump/blower to distribute air through a rotating cleaning arm that moves from filter bag to filter bag and has sensors to align its cleaning arm directly over filter bags before sending a “pulse” of powerful air down through the bag. This pulse type cleaning gives more of a shock to the bag, breaking dust loose, and is therefore better suited for very fine dust that is trying to penetrate the bag on the dirty side.

    All of our systems work with highly accurate magnehelic gauges that measure the pressure of the clean air versus the dirty air in your filter system. When pressure falls, it means the bag or bags are no longer filtering properly.

    Common Questions About Dust Collectors For Manufacturing 

    Why are dust collectors so tall?

    Our full-stack systems can be as tall as 50 feet to accommodate 12-foot filter bags plus another 12-foot clean air compartment for safe bag cleaning. 

    With our cyclone system underneath a bag, our systems can look taller than the competition, but we promise that our proven systems can save you more money on filter replacements and more time and headache on cleaning.

    How often do I have to change bags? 

    That depends entirely on your use and the setting, but changing filter bags is easy .

    What keeps particles from entering the industrial filter bags? 

    Our internal cyclone does a tremendous amount of the heavy lifting to reduce large particulate and detritus. 

    Are your industrial systems OSHA approved? Do you have sprinklers?

    It all depends where you are! We can add sprinkler systems to any industrial dust collection system, and we’re comfortable working within your industry’s unique regulatory framework to create custom, efficiency, and effective tools to keep your facility clean.
