 Flex-Kleen Dust Collectors

Founded in 1959 Flex-Kleen has over 100,000 dust collectors in service worldwide, many still operating after 40 or more years. The product line covers pulse-jet baghouse collectors, cartridge collectors, bin vents, high-pressure collection, and high-vacuum collection, with systems ranging from 30 CFM to 100,000 CFM.

CECO Environmental Flex-Kleen’s engineering depth covers the most demanding technical challenges in industrial dust collection and applications where standard catalog equipment fails. Corrosive process environments. Sanitary food and pharmaceutical requirements. Combustible dusts requiring NFPA-compliant explosion protection.

Low bulk density materials and high temperature and high vacuum applications. Where other equipment has failed, Flex-Kleen systems are frequently the correct solution. What fits for your Indiana facility? We figure that out for you here at Collectors & Filters.

Flex-Kleen iSeries Cartridge Dust Collector

The iSeries is Flex-Kleen’s current-generation plug-and-play cartridge collector, a heavy-duty construction rated for Kst 400 St-3 combustible dusts with explosion vent panel enclosure built in, NFPA 68 compliant. The horizontal filter layout provides tool-free, ground-level filter access without reaching into vertical housings, a meaningful maintenance safety improvement over conventional cartridge designs.

The iSeries is designed for fast deployment without sacrificing performance or compliance, covering chemicals, metal processing, woodworking, mining, plastics, pharmaceuticals, food and beverage, and electronics applications.

Flex-Kleen Pulse-Jet Baghouse Collectors

For high-volume applications, continuous duty, and process conditions that exceed cartridge collector limits, Flex-Kleen pulse-jet baghouses handle dust loads from small production systems through large-scale industrial operations. Reverse pulse-jet cleaning maintains filter performance without interrupting production.

Filter media options cover standard polyester felt through high-temperature woven fabrics and specialty materials for aggressive chemical environments.

Flex-Kleen Replacement Parts

Flex-Kleen replacement parts are available for all makes and models of filtration equipment, not just Flex-Kleen units. Filters, cages, pleated and cartridge media, diaphragm valves, solenoid valves, timers, gauges, and miscellaneous hardware.

If you have a legacy Flex-Kleen unit, a hard-to-find component for an older system, or need cross-reference parts for equipment from other manufacturers, contact us. We find what other distributors can’t.

Fisher-Klosterman High-Efficiency Cyclone Dust Collectors

Fisher-Klosterman has been designing custom air pollution control and product recovery equipment since 1948. Their XQ Series cyclones are the primary industrial cyclone design in use today developed through research to achieve collection efficiencies high enough to eliminate the need for downstream baghouse filtration in many applications. Fisher-Klosterman’s guaranteed performance is backed by sophisticated modeling when complete operating data is provided, not estimated from generic efficiency curves.

XQ Series High-Efficiency Cyclones

Fisher-Klosterman offers seven models in the XQ Series. All covering different levels from standard industrial separation through ultra-high efficiency for fine particulate and product recovery applications. Units are available from miniature collectors through units large enough to require field assembly.

Dual, quad, and multiple-cyclone arrangements address height restrictions or increase collection efficiency. Common inlet manifolds, outlet manifolds, and hoppers simplify ductwork connections for multi-cyclone installations.

Construction options include carbon steel, stainless steel, and any required alloy. Fisher-Klosterman cyclone designs exceed NFPA explosion containment and venting standards. Severe service applications include high temperature, high pressure, erosive particulate, corrosive gases, are Fisher-Klosterman’s core competency, not edge cases.

CECO HEE-Duall Mist Elimination

Most CNC mist problems get solved with a machine-mounted collector. But if you’re running hard chrome plating, anodizing, or any process that generates hexavalent chromium, you need something different. Standard coalescing media degrades in those environments and won’t meet OSHA’s hexavalent chromium exposure limits. That’s where HEE-Duall mist collector comes in, their HEXmaster® and HEPA-HEX™ systems are EPA-tested specifically for those applications, built in corrosion-resistant FRP and PVC rather than steel.

  • HEXmaster®: 3-stage dry scrubber design: can be upgraded to wet scrubber; ideal for oil mists, alkaline mists, and part washing operations
  • HEPA-HEX™: HEPA-rated composite mesh: EPA performance tested and guaranteed for hexavalent chromium, hard chrome plating, and anodizing
  • Construction: Corrosion-resistant PVC and FRP: handles chromic acid, sulfuric acid, nickel, cyanide, and phosphoric acid mists
  • Lowest Pressure Drop: HEXTRACK single composite mesh pad system minimizes energy consumption and maintenance costs
  • Hood Systems: Hoods, ducting, and push-air systems available for complete source capture at the machine enclosure
  • Manufacturer: CECO Environmental HEE-Duall division, Lennon, MI

Why us for the Complete CECO Environmental Portfolio Matters

Standard industrial distributors carry one product type  baghouses, or cyclones, or scrubbers and recommend what they sell regardless of whether it is the correct technology for the application. We supply the complete CECO Environmental portfolio, which means we recommend the correct technology for your specific application without being constrained to a single product line.

A plastics compounder in Columbus with combustible polymer dust gets a Flex-Kleen iSeries with Kst 400 explosion protection. A foundry in Terre Haute with high-temperature abrasive dust gets a Fisher-Klosterman XQ Series cyclone in alloy steel. A large-scale industrial operation with a heavy dust load in Fort Wayne gets a Fisher-Klosterman cyclone as primary separator feeding a Flex-Kleen baghouse.

We match the technology to the application, not the application to the technology we happen to stock.

KB Duct — Modular Industrial Ducting

Kirk & Blum, which has been fabricating industrial sheet metal since 1907. Today KB Duct is one of the most complete modular industrial ducting lines available, offering three distinct system types to match any application:

  • Clamp-Together Duct — Available from 3″ to 24″ diameter in 22-gauge to 10-gauge steel depending on diameter. Applicable to virtually every dust collection system including wood, paper, chemical, fume, oil mist, and abrasive applications.
  • The standard n-butyl rubber gasket covers 95% of applications; FDA silicone is available for food and high-temperature service; Viton and ePTFE gasket materials handle the aggressive chemical applications where standard rubbers would fail. Note: clamp-together should not be used for heavy concentrations of liquid or for positive-pressure dust conveyance, those applications use flanged duct.
  • Welded Flanged Duct — Available in lengths up to 20 feet, material up to 1/4″ thick, seam-welded on 16-gauge and heavier material and on diameters 25″ and above. The heavy industrial end of the ducting spectrum foundries, cement plants, sand and coal conveying, and other severe abrasive applications.

The KB Duct Series 1000 Clamp is their proprietary joining hardware, galvanized steel with an extra-large handle designed for true one-handed operation, built to be opened, repositioned, and re-clamped repeatedly without losing holding force.

Common Questions About CECO Equipment, HEE-Duall & KB Duct

CECO Environmental is a global industrial air quality company that owns several specialized dust and mist collection brands including Flex-Kleen baghouse and cartridge collectors, Fisher-Klosterman cyclones, HEE-Duall mist eliminators and wet scrubbers, Kirk & Blum ductwork, and KB Duct clamp systems. They're the go-to when the application is too demanding for a standard off-the-shelf collector.
Flex-Kleen is CECO's baghouse and cartridge collector brand, founded in 1959 and with over 100,000 systems in service worldwide. Flex-Kleen covers pulse-jet baghouse collectors, cartridge collectors, bin vents, and high-vacuum systems from 30 to 100,000 CFM. They specialize in difficult applications including corrosive environments, sanitary food and pharmaceutical processing, and combustible dust requiring NFPA-compliant explosion protection.
The Flex-Kleen iSeries is designed for a wide range of industrial applications including chemicals, metal processing, woodworking, mining and minerals, plastics, pharmaceuticals, food and beverage, and electronics. It is one of the few plug-and-play cartridge collectors that addresses combustible dust applications without requiring separate explosion protection to be added. The horizontal filter layout allows ground-level, tool-free filter access, which is a meaningful safety improvement over conventional vertical cartridge designs.
Fisher-Klosterman is CECO's high-efficiency cyclone brand used for pre-cleaning large volumes of heavy particulate before downstream baghouse or cartridge filtration. Fisher-Klosterman cyclones are common in high-volume industrial applications including foundries, grain processing, and heavy manufacturing where chip and coarse dust loads would overwhelm filter media directly.
A Fisher-Klosterman XQ Series cyclone is the correct primary separator when filter media would fail rapidly due to high dust loading, when abrasive particulate would destroy bag or cartridge media, when process temperatures exceed filter media ratings, or when product recovery without media contamination is required. Cyclones use centrifugal force rather than filter media to separate particulate, so there are no bags or cartridges to blind, replace, or contaminate the collected material. In heavy-duty applications, the most effective system design is often a Fisher-Klosterman cyclone as the primary separator feeding a Flex-Kleen baghouse as secondary filtration, extending filter life significantly by removing the bulk of the dust load before it reaches the media.
Cyclones and baghouses serve different roles and are often used together. A cyclone separates heavy chips and coarse particulate using centrifugal force with no filter media, making it ideal as a pre-cleaner upstream of a baghouse. The baghouse then captures the fine residual dust the cyclone passes through. For high-volume applications with mixed coarse and fine dust, a cyclone-baghouse combination extends filter life significantly and reduces long-term operating costs. Collectors and Filters sizes both components together as a complete system.
HEE-Duall is CECO Environmental's mist elimination and wet scrubbing brand, formed from the merger of Harrington Environmental Engineering and Duall Air & Water Technologies. HEE-Duall manufactures mist eliminators, packed bed scrubbers, venturi scrubbers, FRP centrifugal fans, and biological treatment systems for industrial air quality applications. Their products are built for corrosive, chemical, and high-efficiency applications where standard steel equipment would fail primarily using fiberglass reinforced plastic (FRP) and PVC construction. Collectors & Filters supplies HEE-Duall mist eliminators for CNC machining, metal finishing, and plating operations throughout Indiana and the Midwest.
The terms are often used interchangeably but describe different approaches. A mist collector typically refers to a machine-mounted unit like the AGET MISTKOP® that draws contaminated air from a CNC machine enclosure through coalescing or centrifugal filter media to capture oil and coolant mist at the source. A mist eliminator, like the HEE-Duall HEXmaster® or HEPA-HEX™, is typically a hood-and-duct system that captures mist at the machine opening using composite mesh pad technology. Mist eliminators are the correct choice for corrosive mists, acid mists, alkaline mists, and hexavalent chromium applications where coalescing media would degrade or where EPA compliance requirements apply. We can help you determine the right technology for your specific machine and fluid type.
If your facility performs hard chrome plating, decorative chrome plating, anodizing, or any process that generates hexavalent chromium mist, OSHA's hexavalent chromium standard (29 CFR 1910.1026) requires engineering controls to reduce employee exposure below the permissible exposure limit of 5 micrograms per cubic meter as an 8-hour time-weighted average. A standard oil mist collector is not adequate for this application. The HEE-Duall HEPA-HEX™ system is EPA performance tested and meets current federal emission standards for hexavalent chromium capture. If you are running chrome plating, anodizing, or stainless steel welding operations in Indiana, contact us to discuss the correct mist elimination specification for your process.
KB Duct clamp-together ductwork is available with four gasket materials matched to application requirements. Standard n-butyl rubber covers approximately 95% of industrial dust collection applications including wood, paper, chemical fume, oil mist, and general abrasive dust. FDA silicone is specified for food processing and high-temperature service. Viton gaskets handle aggressive chemical environments including solvents, fuels, and many chemical process streams. PTFE gaskets are specified for the most chemically aggressive applications. Contact us with your specific process conditions and we will confirm the correct gasket specification before you order.
KB Duct clamp-together is the correct choice for the majority of dust collection ductwork installations, diameters from 3 to 24 inches, negative-pressure systems, and applications involving wood, paper, chemical fume, oil mist, and most abrasive dusts. The clamp-together system installs significantly faster than flanged duct and allows repositioning and reconfiguration without cutting or welding. Flanged duct is specified when the application involves positive-pressure dust conveyance or diameters above 24 inches. Welded flanged duct is the correct specification for foundries, cement plants, sand and coal conveyance, and other high-abrasion service. Contact us with your dust type, duct velocity, and system pressure and we will confirm the right specification.
Yes. KB Duct clamp-together is well suited for welding fume extraction systems. Welding fume is a negative-pressure, low-particulate-load application that falls well within the design parameters of KB Duct clamp-together in galvanized or stainless steel. For facilities extracting hexavalent chromium fumes from stainless or chrome alloy welding, stainless steel duct with Viton gaskets is the correct specification. For mild steel MIG and TIG welding fume, standard galvanized duct with n-butyl rubber gaskets covers the application. Contact us with your weld process and fume volume and we will confirm the right duct specification.
Yes, with the right transition fittings. KB Duct clamp-together connects to existing spiral duct or flanged duct through standard transition couplings. This makes KB Duct a practical choice when expanding or reconfiguring an existing system, adding new drops off a main spiral trunk line, or connecting to a collector with a flanged inlet. We can specify the correct transition components for your existing duct dimensions and connection type. Contact us with your duct sizes and connection details and we will put together the right parts list.
