kassettfiltre

Kassettfiltre, or cartridge filter, is a replaceable filtration element designed to remove particulates from liquids or gases within a filter housing. The cartridge consists of a perforated core, end caps, and a filtration media that can be pleated, depth-type, or block-style. Common media include polypropylene, polyester, cellulose, glass fiber, and activated carbon, sometimes in composite forms. The cartridge is sealed in its housing by end caps and gaskets to prevent bypass.

Filtration occurs as fluid flows through the cartridge and particulates are captured in the media. The rate and efficiency depend on media type and micron rating. Pleated cartridges offer high surface area; depth filters capture contaminants throughout the media thickness; carbon cartridges provide adsorption of certain chemicals.

Sizes and configurations vary. Consumer water filters typically use 10-inch cartridges with ratings from 1 to 20 microns, while industrial systems use larger diameters and lengths, such as 4.5 inches in diameter and 10, 20, or 30 inches long. Cartridges are selected based on flow rate, allowable pressure drop, and target particle size.

Applications span drinking water treatment, food and beverage processing, chemical and pharmaceutical production, HVAC and dust filtration, and automotive and industrial oil and fuel filtration. They are commonly used as drop-in replacements in standardized housings and are designed for easy replacement rather than cleaning.

Advantages include easy replacement, compatibility with many housings, and high dirt-holding capacity. Disadvantages include ongoing consumable cost, and the potential for bypass if seals fail or the cartridge is undersized. In drinking water systems, many kassettfiltre may be certified to standards such as NSF/ANSI, reflecting product safety and performance claims.
