1. Application
The first thing to consider is application. The type of application will help us understand the machining processes, the size and kind of dust and other air contaminants being generated, and if high-temp or fire resistance is required.
Most common applications include:
• Grinding dust
• Welding fumes
• Process dust
• Flame retardant
• High temperature
2. Work environment
The work environment not only has an effect on the performance of the dust collector filters, but also impacts effectiveness, efficiency, and filter media cleanliness. When buying replacement dust collector filters it is important to know what is being filtered and if there are any air quality regulations that need to be met.
Using incorrect dust collector filters can result in poor and unsafe air quality, higher maintenance costs, and equipment malfuction.
3. Temperature
Understanding temperature requirements is crucial when buying replacement dust collector filters. The applications and machining processes that are present may require filters of a specific media to accommodate combustible dust and high temperatures.
Knowing the type of dust and/ or other air contaminants being filtered lets us know if it is abrasive or corrosive, which also plays a factor in filter type. Dust collector filters that are able to withstand extreme temperatures and ensure that the workplace is safe and free of explosion risks are key to a compliant facility.
4. Filter construction
One of the most important factors when determining what dust collector filters are right is the construction of the filter itself. The construction of dust collector cartridge filters differ greatly based on a number of things, including pleat count and pleat depth, media type, configuration, material, size, and more.
Knowing the pleat count is used to determine square feet and pleat depth gives insight on surface loading, loading capactiy, and airflow rates. The media type must meet the applications, work environment, and machining processes requirements. Common media types include Cellulose, 80/20 Cellulose Poly Blend, 100% Spun Bond Polyester, with flame retardant or holiophobic treatment, polyester, natural fibers, woven and non woven felts, and synthetics such as Polypropylene.
The configuration on the top and bottom of the filters determine if they can accommodate the type and size of dust collection system you are working with. The inside and outside diameter, the length, square footage, and cellplate size make certain that the filters you choose are compatible with the dust collection system.
5. Resistance
Filter resistance is the static-pressure drop across the filter at a designated face velocity. The correct dust collector filter prevents build-up and filter failure by providing the proper resistance for filter loading and dust holding capacity at difference pressure drops.
Resistance ensures that the filter is made of media that can withstand the wear and tear of the dust and other air contaminants being generated in the workshop or facility.
6. Dust Collection System
The CFM and the size of the dust collection system allows us to choose filters that have the capabibility to meet requirements and guarantee effectivness and efficiency. Knowing the type of dust collection system also allows us to determine if it is a cartridge collector, baghouse, shaker, pulse jet, etc., how the filters are loaded, and how many filters it holds.
