Sepor’s laboratory bench top batch vacuum filter is ideal for dewatering slurries, allows cake washing, and is easy to use and clean. The filter consists of a rubberized base with a elevated drain channel, covered with a 10 mesh stainless steel screen, a 1/4″ NPT drain pipe, two hand lug attachments for holding the 10 inch diameter by 6 inch height steel cylinder body firmly in place, a package of 100 each , high wet strength filter papers and one filter cloth with 25 micron pore openings. The filter will hold up to 2 gallons of slurry.

To use the batch vacuum filter, the filter drain is connected to a filtrate receiver, such as the 2,000 cc plastic filtrate receiver, and a vacuum pump, such as the ones illustrated below, or a vacuum source is connected to the filtrate receiver. A wetted piece of filter paper is placed on the screened base and the upper cylinder is quickly clamped into place. The vacuum is connected and turned on, and the slurry is poured into the batch vacuum filter. Dewatering is usually rapid, with the filter time depending upon the capacity of the vacuum pump used, and the characteristics of the material being filtered.
