Depth Filter Cartridges

Your Subtitle Goes Here
Designed with a thick filter media composed of multiple layers, such as cellulose or synthetic fibres, depth filter cartridges offer a high dirt-holding capacity to capture particles of various sizes throughout the depth of the media. They are ideal for applications where extended service life and reliable particle removal are essential, including food and beverage, pharmaceuticals, and water treatment.

Depth Filter Capsules

Combine the advantages of depth filtration in a compact and easy-to-use format, depth filter capsules incorporate a depth media that efficiently traps and retains particles throughout its layers. With their convenience and excellent particle removal capability, depth filter capsules are suitable for small-scale or portable applications, providing reliable filtration in industries such as laboratories, research facilities, and biotechnology.

Gradient Depth Filters

Constructed with a graded density structure, with varying pore sizes throughout the filter media, gradient depth filters are designed to remove larger particles trapped on the outer layers and smaller particles captured deeper within the media. Gradient depth filters offer enhanced dirt-holding capacity and longer service life, making them well-suited for applications with challenging filtration requirements, such as fine chemicals, cosmetics, and paints.

Pleated Depth Filters

Using pleated filter media, the pleated depth filter increases surface area to maximise filtration. The pleated design enhances particle capture and extends the filter’s capacity to hold contaminants. These filters are commonly used in industrial processes, wastewater treatment, and HVAC systems, providing efficient and cost-effective particle removal.
