Air Filtration

With decades of experience in commercial air filtration, not only do we stock and manufacture the highest quality air filtration products, we employ knowledgeable technicians and sales people to help you determine the best filter for your application. We can analyze filter media and contaminants in our comprehensive St. Louis lab or at your location. We partner with filtration industry leaders, and FSP-manufactured dust bags are compatible with–and often recommended by–original equipment manufacturers.

OEM Dust Bags

Our durable synthetic or natural fiber dust bags can lower your costs by increasing baghouse efficiency. We offer long-lasting replacement filter dust bags for more than 120 brands, including: Kice, Airlanco, IAC, Sly, Flex-Kleen, Mikro-pul, Pneumafil, Carter Day, Pang Borne, MAC, Wheelabrator, DCE Volkes, and Young. If you don’t see your collector listed here, just ask. If we don’t have the dust bag you need in stock, we will get it!

Custom Sewn Dust Bags

Our engineering and design department can create custom dust bags in any shape, size or type. Our expansive variety of top-quality fabrics supports fine or coarse filtration for any dust collector. FSP custom bags are easily installed and changed out and offer numerous cost-saving options. We are your solution to problem applications!

Electric Fan Motor Covers & Fan Covers

Extend the life of your fan motor by protecting it from harmful dust and airborne particles. Our fan covers are available in standard and custom sizes in polyester, fiberglass and foam. All American-made FSP electric motor fan covers offer a tight, protective fit, yet remain easy to install and remove.

FSP industrial fan covers help you ensure air and product purification without restricting air flow. Our fan covers keep air particles out without placing an additional resistance on the fan motor. Disposable polyester and foam fan covers are available in standard and custom sizes.


Filtration System Products stocks disposable and cleanable HVAC filters for immediate delivery. Our inventory includes: auto roll and bulk rolls and pads, cartridge filters, HEPA filters, multi-pocket bag filters and filter panels that range from low to high efficiency in polyester or glass media. Our comprehensive inventory includes filters from industry giants, such as Purolator, American Air, Farr, and Columbus Industries as well as many other manufacturers. If we don’t have the OEM filter for your equipment, it is no problem for us to custom make one to your specifications.
