Centrifuge Cloths
Menardi is able to supply centrifuge cloths to retro-fit all standard designs of centrifuge filters. Menardi manufactures centrifuge cloths in many styles to fit all OEM designs. Options include cord and Velcro© ends and various backing cloth choices. Centrifuges are used in a variety of industries and serve several functions including clarification, classification, purification, dewatering, washing, and extraction. Centrifuges are designed around criteria such as size of particles to be separated, feed rates, solids concentration, and the required solids dryness.

Typical Applications:
Fine Chemicals/Specialty Chemicals
Catalyst Recovery

A wide selection of filter media is available to meet your required performance requirements:
Fiber types – polypropylene, polyester, nylon, PTFE
Yarn types – Woven monofilament, woven multifilament, staple fiber spun yarns, staple fiber, woven combination fabric (i.e., monofilament / multifilament)

All cloths are laser cut from computerized pattern designs to ensure precision and repeatability. The Filter Press is a highly efficient, compact, dewatering filter for separating solids from liquid slurries in the form of compressed cake. Its major components are a structured framework, filter chambers, and filter cloth. These presses work on feed pressure or squeeze pressure to reduce liquid content in process or waste slurries or to reduce solid content in a product.
