A Brief Introduction Of Hawach Filter Bag And Filter Capsule

With years of experience in the production line of lab consumables, Hawach is known for its outstanding performance in the industry, who constantly upgrade their products to meet the international standards. Hawach is able to provide on-time deliveries with high quality, thanks to a team of professionals and continuous hard work.

Hawach filter bag
The filter bag is made of porous short fiber non-woven fabric or nylon woven mesh by heat sealing or sewing. It has a deep filtering structure and good integrity. There are four kinds of materials at choice: polyester needle (PET), PP needle felt (PPF), PP flat sheet (PPP), nylon monofilament (NMO); and two kinds of interface materials: stainless steel ring, PP plastic ring. It features deep filtration, especially large filtration flow, low resistance, long service life, low cost, no fiber shedding, and easy operation.

Hawach filter bag has been widely used in the petrochemical industry; filtration of sugar, spices, juice, tea, etc. in the food industry; filtration and solvent filtration in polyester and acrylic production in the textile industry; recycling of valuable components in the pharmaceutical industry, gelatin, vitamins, syrup, etc.

Hawach capsule filter
The capsule filter is also called a disposable filter. The outer shell is made of high-temperature polypropylene material and the inner filter cartridge is hot-melted and welded together with the folding filter cartridge. It does not contain adhesives and other chemicals. The filter has different filter membranes and pore sizes, which can be autoclaved, suitable for filtering small dose liquids such as 1-20L laboratory, gas or industrial precious small volume liquid.
