In many areas of the food and pharmaceutical industries, vessels, piping and filter systems are sterilized by steam. The steam required to sterilize these systems may contain a considerable amount of rust or other pipe scale. The resulting contaminated steam may cause serious faults in the system. If the steam is contaminated, the life of valves, filters and other ancillary equipment is shortened.
Parker Zander HS and DPL Steam Filter Element Series are manufactured from micro porous sintered fibers with a diameter of 2 to 40 microns.
The fibers are first worked into a homogenous mesh that, in a subsequent sintering process, is made into a wire fabric, as support material. The filter medium can then be rolled to the required density. The extremely high porosity of the metal fibrous web of up to 80% and the very high filter area offered by the pleated filter medium ensure that, in comparison with a depth medium, a large number of pore cross sections is available for the steam transfer. This fact ensures an optimum relationship between filter porosity and filter capacity. Dirt, dust and rust particles are not just completely retained on the filter surface, but also within the filter itself.
The HS and DPL Filter Element Series are not just limited to the filtration of steam. They are also suitable for the filtration of air/gas, hot water and chemicals in all areas of chemical industry, the food industry, the electronics industry, biotechnology and pharmaceuticals.
HS and DPL Steam Filter Elements are used wherever large quantities of steam are required to be purified to culinary quality with minimum pressure loss and long filter service life.
