Advantages of Industrial Cartridge Filters

When searching for a disposable filter for your system, there are two different types to consider: cartridge filters and bag filters. Bag filters are made of several materials and are generally considered to be surface filters, while cartridge filters can be either surface or depth filters. The big questions is, what type of filter best suits the needs of your company? Consider the information below to help with the selection process. Keep in mind, every solution is different, and it is possible that your company may require more than one piece of equipment for efficient filtration.

What Are You Trying To Filter?

This question is crucial, as the type of contaminant being filtered can be stopped more efficiently by one type of filter than another. For example, most cartridge filters are going to be very effective against very small contaminants, at a concentration of less than 50 ppm. These filters will be effective against fine contaminants but may not be as efficient when filtering larger particulate, at higher concentrations. Filtra-Systems industrial cartridge have a high contaminant removal rate. These cartridges have very fine, highly concentrated fibers on the inside of the cartridge, and larger fibers with more porous openings on the outside of the cartridge to catch a large amount of contaminants.

How Do You Want To Filter

How much space needs to taken up by the filter? To process larger flow rates, larger filters housings are needed. Alternately, a larger filter housings can be installed in applications with low flow rates, so that the filter will not need to be changed as often. Two different cartridge filter designs are offered: depth and surface. A depth filter looks like a block of material, and catches material throughout the cartridge. A surface filter will typically have a pleated material, and only catches solids on the outer surface. These are typically absolute rated filters (catches 99.5% of contaminants at a given micron rating) while depth filters are nominally rated.

The Advantages

Overall, depth cartridges have the advantage of thickness and depth, allowing for more material to be caught by the filter. These cartridges are also easily disposable and are easily replaced.
