Abstract: Cleaning and oil filtering apparatus for removal of all solid waste material from a container generally containing hot cooking oil and for filtering the cooking oil, includes a pump, by which the cooking oil can be moved through an intake insertable at the bottom of the container, a holding tank for temporary storage of cooking oil filtered through the filtering elements, and a discharge insertable in the container and through which cooking oil from the holding tank can be discharged or cooking oil from the container can be moved through the intake and filtering elements, and discharged to the container.

Abstract: A filter assembly for use in an air filtration unit, particularly for filtering cooking vapors. The assembly includes a filter disposed across an air flow and a grease pre-filter located upstream of the filter. The grease pre-filter is formed principally from wool fiber having an approximate density of 150-200 g/m2 and a loft of substantially 15-20 mm. The use of such a pre-filter substantially prolongs the service life of the filter before cleaning is required.
