    Different Types of Baghouses & Baghouse Filters

    There are three types of baghouses: shaker discharge, reverse air, and pulse jet. All three types function by pulling a vacuum through a filter media. The filter media collects solid particles until a dust cake forms. Once this dust cake is established, and assuming the correct media and conditions are in place, the discharged air or gas will be free of particles within acceptable limits.

    It’s important to note that the filter bag itself does not perform the filtration in a dust collector. Instead, either the initial dust cake or a precoat captures fine particles. Read more here about what are baghouse filters and how they work.

    Filter Bag Shaker Bag

    Shaker

    Shaker dust collectors are among the earliest types of baghouse systems and remain popular in smaller sawmills. These systems often feature a large bag fitting over a 55-gallon drum, with bag lengths ranging from 10 to 20 feet. A rope and pulley mechanism at the top of the bag allows operators to shake the bag, breaking apart the dust cake inside for easy discharge.

    Tubular shaker collectors, common in cement plants, use polyester sateen weave fabric bags. These bags vary from 3 to 12 inches in diameter and 2 to 14 feet in length. Compartments can hold a few to hundreds of bags, with multiple compartments often connected to the same dust stream. This design allows for continuous filtration while cleaning.

    Filter Bag Pulse Jet

    Pulse Jet

    Developed in the 1960s, pulse jet dust collectors build a dust cake on the outside of fabric filters. A blowpipe above the bags in the clean air plenum delivers a jet of air to each bag in rows of 6-10 tubes. A venturi seated within the open end directs the pulse into the bag for even cake discharge.

    Each fabric bag has a wire cage inside to prevent collapse during filtration while the bag is under vacuum. The top of each bag connects to its cage and cell plate with a snap band, bolt-on flange, or hose clamp. The bottom of the bag is typically a flat disc, sometimes with a wear strip to prevent abrasion from one bag rubbing against another and forming a hole.

    Filter Bag RF-Torit

    RF-Torit

    RF-Torit bags are a popular choice in industrial dust collection systems, known for their efficiency and durability. These bags are designed to handle high dust loads and provide superior filtration performance.

    In baghouse systems, the dust-laden air enters the baghouse and passes through the bags. The dust particles are captured on the outside surface of the bags, forming a dust cake that enhances filtration efficiency.

    Periodically, a reverse air or pulse-jet cleaning mechanism is activated to dislodge the dust cake, allowing it to fall into a collection hopper below. This self-cleaning feature ensures that the bags maintain optimal performance without frequent manual intervention.

    Replacement Baghouse Filters for Any Industry

    • Asphalt – Our filters are designed to withstand the abrasive and high-temperature environments of asphalt production. Whether for hot mix or batch plants using natural gas, waste oil, or fuel oil, we supply replacement filters compatible with OEMs like Astec, Gencor, and Standard-Havens.
    • Cement – We offer filters for all areas of a cement plant, including kiln baghouses, silo bin vents, and nuisance dust collection. Our filters exceed all EPA emissions standards (NESHAP, CMAT, MACT for Portland cement, PM2.5, etc.) and are compatible with dust collectors from ABB/Flakt, Flexkleen, FLS/Fuller, Mikropul, Norblo, Redecam, Solios, and other OEMs.
    • Chemical – Our filter fabrics are suitable for handling acidic or alkaline compounds and other corrosive or abrasive elements found in chemicals like lime, calc, fertilizer, and plastics. We offer special treatments and fabrics and can recommend the best combination for optimal performance and cost-efficiency.
    • Food Processing – We provide FDA-approved food-grade fabric filters for dust collectors used in food production, transportation, and packaging. Our filters are ideal for dust collectors on milling equipment, blenders, mixers, granulators, grain elevators, storage silos, and more.

We offer fabrics and coatings that withstand high temperatures and provide high-efficiency fume and smoke collection. Our filters fit major OEMs like Amerex, Norblo, and Wheelabrator.
    • Power Generation and Industrial Boilers – Our filters exceed the latest EPA emissions regulations for boilers and power generation, including Mercury and Air Toxics Standards, Boiler MACT, and NESHAPs. We have extensive experience with biomass and coal power production facilities, helping them meet new EPA regulations. Our filter fabrics and treatments include PPS, P84, PTFE/Teflon (fabric), fiberglass, and ePTFE membrane.
    • Wood, Sand, Minerals – FabCo Industrial Services provides specialized filters for dust collectors used in the wood, sand, and minerals industries. These applications often require filters with flame-resistant coatings or construction from nonflammable materials to ensure safety and efficiency.

    Choose the Right Baghouse Filter for Optimal Performance

    Selecting the right baghouse filter is crucial for efficient system performance. The wrong filter can lead to inefficiency, excess emissions, and damage to system components. The correct filter maximizes performance, extends filter life, and reduces downtime, ultimately saving you money. Ensuring proper filter selection and installation is essential.
