Polymer Leaf Disc Filters
Constructed from sintered wire cloth laminates or sintered non-woven fiber metal felt media, these polymer leaf disc filters are the product of choice for polymer film and specialty polymer producers. The unique design and configuration of the leaf disc assembly maximizes the effective filtration area while minimizing the residence time of the polymer itself, thereby reducing the risk of polymer degradation.
Features & Benefits Fiber metal felt depth media are available from 3 µm – 60 µm absolute. Sintered wire cloth media is available from 10 µm – 200 µm absolute. Materials/Method of Construction Polymer leaf discs are available in 316L stainless steels and other alloys. These alloys, combined with our advanced construction/welding methods, result in excellent corrosion resistance and a useful life of many cycles. Sizes & Center Hub Designs

Extended Area Screen Packs
In addition to traditional flat screen packs, Everest Equipments manufactures extended area screen packs for applications where pack life is a primary consideration. These extended area screen packs are manufactured with multiple layers of precision woven wire cloth and/or non-woven fiber metal felt. This media is pleated to provide much more surface area than a flat screen pack. Media type, pleat height, and pleat spacing are determined after careful consultation with the user. Flow rate, viscosity, pressure drop and desired pack life are among the items that are typically considered.
Available ratings range from 2 - 200 microns for woven wire cloth and 3 - 75 microns for non-woven fiber metal felt.
Sintered laminate Packs
Sintered Laminate Packs are multi-layer composites of woven wire mesh and / or fiber metal felt. These media composites are diffusion-bonded for high-pressure polymer filtration applications.
Sintered screen packs are used in a variety of applications including polymer film, fiber and bulk resin filtration. In addition to standard discs and rectangular shapes, custom configurations such as conical screen packs are also available. Sintered screen packs are typically recommended for filtration ratings from 5 µm to 40 µm. Fiber metal felt media are typically included in screen packs rated at 5 µm to 40 µm as a means of enhancing gel retention or increasing screen pack onstream life. |
