Ultramesh P-SM Stainless Steel Mesh
Designed for cost effective filtration of both liquids and gases, the Ultramesh P-SM is constructed of 304 stainless steel mesh supported by an inner core of the same material. Elements are available with absolute retention rates from 5 to 250 micron, and can be regenerated with an ultrasonic bath or in-line via back-flush. In addition, P-SM elements have a broad operating temperature range of -60ºF to 400ºF

Ultrex P-GS Sintered Stainless Steel
Perhaps our most versatile filter, our Ultrex P-GS element is suitable for use in filtering steam, gases and liquids. The element body is a weldless tube of sintered stainless steel between stainless steel end caps. Particle retention rates of 1, 5 and 25 micron are available, and P-GS elements can be regenerated many times. The high porosity level of the P-GS element gives it a high dirt-holding capacity and a low pressure drop. P-GS filter elements have a broad operating temperature range of -4ºF to 410ºF.

Ultradepth II P-BE Tank Vent Filter
Sharing many of the features of our P-SRF sterile air filter, the Ultradepth II P-BE filter has been designed specifically for use in tank vent applications. Tank ventilation, or aspiration, takes place at atmospheric pressure. Therefore, the P-BE filter element has been designed to minimize pressure drop at this operating pressure while still providing an absolute particle retention rate of 0.01 micron. The P-BE element meets FDA requirements for food contact in accordance with CFR Title 21. Like the P-SRF, it can be sterilized up to 100 times in-line with steam or in an autoclave.
