PE and PTFE filter elements are available to assure a full complement of filter media for our disposable filter elements and stainless steel filter types. PTFE filter elements (also called Teflon filter elements) are produced by sintering pure PTFE granules without any other substances used in the filter construction. These filter elements are usually offered only when 100% pure PTFE/Teflon is required. When used with our FF series PTFE filter housings a 100% PTFE filter solution is available.
It is normally preferable to offer a K type disposable filter element where suitable, as both pressure drop and service life characteristics are superior to PTFE filters. PTFE offers the performance advantages of a higher maximum temperature of up to 200°C, as well as better chemical resistance to certain substances. PTFE elements can also be ultrasonically cleaned.
PTFE filter elements can be supplied in 2, 20 and 40 micron grades from stock, Other grades are available to order. Ideal for applications where a low cost plastic filter element is required, Polyethylene filter elements are sintered using pure PE granules to deliver a maximum operational temperature of 150°C.
