Donaldson Compressed Air & Process Filtration offers a broad selection of filter elements for a wide range of air and gas filtration applications. By selecting the right filter material and appropriate filtration rating, operating costs can be minimized while maintaining product integrity and process efficiency. From stainless steel mesh prefilters to sterile membrane final filters, Donaldson filter elements will help you optimize your process.

	Donaldson Ultrex P-GS Sintered Stainless Steel Filter Element Perhaps our most versatile filter, our Donaldson Ultrex P-GS filter 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 filter elements can be regenerated many times. The high porosity level of the P-GS filter 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. Certificate of Performance
	Donaldson Ultrapolyplea PP Pleated Polypropylene Element The Donaldson Ultrapolyplea PP filter element is constructed entirely of polypropylene, including the pleated filter media, end caps and support cage, giving it a wide range of chemical compatibility. Nominal retention rates are available from 0.2 to 30 micron. The filter elements contain no binders or adhesives and meet FDA requirements for food contact in accordance with CFR Title 21. PP filter elements are an economical pre-filter for gases and liquids. Material & Performance Validation Materials of Construction to CFR Title 21
	Donaldson Ultrapolyplea PP100 Pleated Polypropylene Filter Element The Donaldson Ultrapolyplea PP100 filter element is constructed entirely of polypropylene, including the pleated filter media, end caps and support cage, giving it a wide range of chemical compatibility. Absolute retention rates are available from 0.65 to 40 micron. The elements contain no binders or adhesives and meet FDA requirements for food contact in accordance with CFR Title 21. PP100 filter elements can be sterilized in-line with steam or in an autoclave. Materials of Construction to CFR Title 21
	Donaldson Ultrateflomem PF-PT Teflon® Membrane Filter Element Our Donaldson Ultrateflomem PF-PT filter element uses a Teflon membrane media for absolute retention rates of 0.1 to 1 micron. PF-PT filter elements are compatible with a wide range of chemicals, including highly aggressive liquids and gases, and meet FDA requirements for food contact in accordance with CFR Title 21. The filter elements can be sterilized in-line with steam or in an autoclave, and offer long service life with low pressure drop. Material & Performance Validation
	Donaldson Ultrapolymem PF-PP Polypropylene Membrane Filter Element Made from 100% polypropylene, the Donaldson Ultrapolymem PF-PP membrane filter element is an economical alternative to more expensive PTFE filters. PF-PP filter elements have a broad range of chemical compatibility with absolute filtration efficiency of 0.1 and 0.2 micron. All components meet FDA requirements for food contact in accordance with CFR Title 21, and the elements can be sterilized in-line with steam or in an autoclave. Material & Performance Validation Materials of Construction to CFR Title 21
	Donaldson P-SRF Process Sterile Air Filter Element The Donaldson P-SRF sterile wrapped depth air filter elements with PTFE support material have a retention rate of ≥99.99998% related to ≤0.2 micron ensuring safe and sterile filtration of compressed air, process air, technical gases and vent applications. The P-SRF filter elements’ high-quality stainless steel construction ensures excellent mechanical stability, thermal resistance up to 392°F, and more than 100 sterilization cycles possible at specific conditions. All components meet FDA requirements for contact with food in accordance with the Code of Federal Regulation (CFR), title 21, are manufactured in accordance with DIN EN ISO 9001, integrity tested at the plant, and have validated retention of bacteria and viruses, LRV > 7/cm2 (Brevundimonas diminuta), and LRV > 9/cm2 (MS2 – Coliphagae).  The P-SRF provides low pressure drop, high dirt-holding capacity, great strength, and long service life to dramatically reduce your operating costs. Materials of Construction to CFR Title 21
	Donaldson P-SRF N Sterile Air Filter Element Donaldson P-SRF N sterile pleated depth filter element is used for sterile filtration of compressed air, process air, technical gases and vent applications. The retention rate is >99.99998% related 0.2 um and >99.9999998% related to 0.02 um ensuring safe and sterile filtration of process gases. The P-SRF N provides low pressure drop at high flow rates, high dirt-holding capacity, and long service life to dramatically reduce your operating costs.
	Donaldson Ultrac™ P-AK Activated Carbon Filter Element Donaldson Ultrac P-AK adsorption filter element consists of two filter stages. At the activated carbon stage, oil and hydrocarbon vapors and odors are removed by adsorption. Particles are removed at the microfiber fleece depth filter stage. A special flow insert ensures optimum flow distribution through the filter from inside to outside. This creates minimum pressure loss and ensures maximum usage of the filter material.
