US FABRICATED
Filtrus designs and fabricates baghouse systems, cartridge collectors, and complete turnkey dust collection solutions for grain processors, pharmaceutical plants, metal fabricators, chemical operations, and food manufacturers. NFPA 660 compliant. US-manufactured.
Systems
Every Filtrus system starts with your process data. Airstream conditions, dust type, grain loading, and facility layout determine the design - not a product matrix.
The workhorse for high-grain-loading industrial environments. Pulse jet baghouses handle 10,000 to 100,000+ CFM with automated filter cleaning, built for continuous-operation facilities. Designed for grain processing, metal fabrication, chemical, and mining applications.
High-efficiency filtration in a compact footprint. Filtrus cartridge collectors use PTFE and nanofiber media rated to MERV 15+ for applications where fine particle control is critical - pharmaceutical, food, and precision manufacturing environments.
First-stage separation removes bulk particulate before the primary collector, extending filter life and reducing pressure drop. Designed as integrated stages in complete dust collection systems for grain, wood fiber, and heavy-particulate processes.
From airstream characterization and ductwork engineering through fabrication, installation, and commissioning - Filtrus manages the complete scope. ACGIH and SMACNA design standards applied throughout.
NFPA 660 requires every facility handling combustible dust to complete a Dust Hazard Analysis. Filtrus systems are engineered to address DHA findings - explosion venting, spark arrestors, grounding, and filter media selection included in the design scope.
Filter bags, cartridges, pulse valves, rotary airlocks, and controls - stocked and shipped from our US fabrication operation. Engineers available for troubleshooting, performance audits, and system optimization throughout the equipment lifecycle.
Industries
Industrial dust collection is not a one-size application. Filtrus builds systems for industries where getting it wrong carries real consequences.
Grain dust is combustible - NFPA 660 Chapter 21 mandates specific collection and explosion prevention requirements for grain elevators, feed mills, and processing facilities.
Cross-contamination prevention and 316SS sanitary construction are standard requirements. Filtrus systems meet FDA facility air quality requirements.
Aluminum, magnesium, and titanium dusts carry explosion risk under NFPA 660 Chapter 22. Welding fume, grinding dust, and plasma cutting particulate require application-specific filter media and collection configurations.
Reactive and hygroscopic dusts demand filter media, housing materials, and explosion protection measures matched to the specific compound. Filtrus works from your dust characterization data.
Sugar, flour, starch, and spice dusts are combustible - NFPA 660 Chapter 21 applies. Sanitary design and food-grade construction materials are available across all Filtrus system types.
Commercial sawmills, engineered wood plants, and large-scale millwork facilities require systems built for sustained high-volume operation.
Combustible dust classification varies by compound. Filtrus specifies filter media and static dissipation based on your material's Kst and MEC values.
High grain loading, abrasive particulate, and extreme environments require robust housing construction, abrasion-resistant inlet design, and silica dust compliance with OSHA's 50 µg/m³ PEL.
Off-shelf dust collectors are built around average conditions. Industrial processes are not average. A system sized for typical grain loading in a standard configuration will fail under the specific conditions of your facility - elevated temperatures, atypical particle sizes, high moisture content, or unusual inlet geometry.
The most common failure modes are mismatched air-to-cloth ratios, undersized inlet ductwork, wrong filter media for the dust type, and missing explosion protection. Each of these is a design decision that a catalog configuration cannot make for your process. Each one has a cost: premature filter failure, production downtime, OSHA citation, or worse.
Filtrus starts with your process data - dust type, particle size distribution, Kst value if applicable, inlet airflow conditions, temperature, moisture content, grain loading, and facility layout. The system is specified from those inputs. Ductwork is designed to ACGIH Industrial Ventilation Manual and SMACNA standards. Equipment is selected to match, not the other way around.
The cost of a properly engineered system is lower than the cost of replacing an undersized one. Production downtime, OSHA fines, insurance consequences, and the capital cost of a second system purchase are all avoidable with correct engineering at the outset.
Your process has specific inlet conditions. Your system should be engineered to match them.
NFPA 660 became effective December 6, 2024. It consolidates six previously separate combustible dust standards - NFPA 652, 654, 61, 484, 655, and 664 - into one unified framework. Every US facility that handles or generates combustible dust must now have a completed Dust Hazard Analysis (DHA) and remediate any identified gaps. Penalties for non-compliance include operational shutdowns and daily fines.
How we work
Here is what working with Filtrus looks like.
We review your process data: dust type, grain loading, airflow requirements, facility layout, and compliance history. No online configurator. No catalog.
Dust type, particle size, Kst/Pmax values if applicable, inlet temperature, moisture, and grain loading are documented and used as design inputs.
Ductwork per ACGIH and SMACNA standards. Equipment selection and sizing. Compliance review against NFPA 660, OSHA, and EPA requirements. Drawings and documentation package.
Your system is built in the United States at our fabrication facility. Quality checks at each fabrication stage. Factory performance validation before shipping.

Coverage
When your facility needs an industrial dust collection system or a full baghouse system sized to real process data, you work with engineers who fabricate equipment in the United States and support industrial facilities nationwide.
US fabrication shortens freight and coordination for plants in the central US compared to overseas sourcing. Facilities in Oklahoma City, Tulsa, Wichita, Kansas City, Dallas, and Houston see practical domestic freight and mobilization timelines for large equipment. That matters when you are staging a collector, duct runs, and startup support. Every Filtrus system is built to be NFPA 660 compliant by design - not retrofitted after the fact.
Nationwide service does not mean anonymous support. Filtrus engineers travel for site surveys, installation oversight, and commissioning in Denver, Houston, and other major industrial hubs, as well as rural processing sites across the country. Whether you are in the central US, the Gulf Coast, or on either coast, you get direct engineer contact from inquiry through start-up.
FAQ
System sizing starts with your total process airflow requirements - the CFM needed across all capture points, plus a 15-20% design margin. Dust type, grain loading, inlet temperature, and moisture content all affect filter media selection and housing design. Filtrus engineers size every system from your process data. Contact us to start a sizing consultation.
NFPA 660 is the unified combustible dust standard that became effective December 6, 2024. It applies to any facility that handles or generates combustible particulate solids - including grain, wood, metal, pharmaceutical, chemical, and food processing operations. Compliance requires a completed Dust Hazard Analysis and remediation of any identified gaps. Filtrus systems are engineered to address DHA findings directly.
Baghouse systems use fabric filter bags and are the standard choice for high-grain-loading, high-temperature, and large-volume applications. Cartridge collectors use pleated filter media in a compact housing and are preferred where fine particle control and MERV 15+ filtration efficiency are required - pharmaceutical, food, and precision manufacturing environments. The right choice depends on your dust type, particle size, airflow volume, and space constraints. Filtrus engineers will recommend the correct configuration for your process.
Lead time depends on system complexity and current fabrication queue. US fabrication is consistently faster than overseas alternatives, which typically run 16-26 weeks. Contact us for a current lead time estimate on your specific project scope.
Filtrus provides full turnkey scope - engineering, fabrication, field installation coordination, and commissioning. We also work with your preferred installation contractor when required. Either way, a Filtrus engineer is on site for startup and performance verification.
Filtrus builds dust collection systems for grain processing, pharmaceutical manufacturing, metal fabrication, chemical processing, food manufacturing, commercial wood products manufacturing, plastics, rubber, and mining operations. If your process generates industrial particulate and requires NFPA 660 or OSHA-compliant dust collection, contact us to discuss your application.
