Teflex Series absolute PTFE membrane filter cartridges
Teflex Series absolute PTFE membrane filter cartridges provide full particle retention. Their endcaps have center cores and outer support cages constructed of polypropylene for increased durability. These cartridges can be used as filters in electronics, food and beverages, high-purity chemicals, and general-purpose†filtration applications. They are rated to withstand temperatures up to 176°F (80°C), as well as a maximum differential pressure of 50 psid (forward) or 40 psid (reverse). They can be sterilized or autoclaved, and are available in 10-, 20-, 30-, and 40-in. lengths, with a nominal outer diameter of 2.75 in. Custom configurations are available for unique application requirements.

Driflex oil-conditioning system
The Driflex oil-conditioning system completely removes free, emulsified and dissolved water from a wide variety of industrial and mobile lubrication and hydraulic systems. Dirt and water contamination is responsible for 70–80% of lubricated-equipment wear and failures. This system reduces water concentration and improves particulate-filtration effectiveness to optimize oil condition and minimize equipment wear, reducing maintenance expenses and costly downtime. The Driflex technology relies on a fundamental principle of mass transfer to achieve oil dehydration: since moisture diffuses from regions of high concentration to low concentration, moisture-contaminated oil loses moisture to dry air. The system pumps oil from its reservoir through a high-efficiency particle filter, which cleans the oil and protects the dehydration contactor from damage. As the oil flows through the contactor, a sweep of extremely dry air creates a moisture differential, causing moisture to be transferred from the oil to the air. The moisturized air is then exhausted from the system. No wastewater or other disposables are created, and there are no moving parts or flow/level controls to adjust. The system can operate as a dedicated unit on a particular lubricant reservoir to provide continuous conditioning, optimizing the oil without the fluctuations that typically occur with periodic purification or replacement.

Resflex Series resin-bonded filter cartridges
Resflex Series resin-bonded filter cartridges use a two-stage design to provide reliable, effective filtration. Their outer spiral prefilter wrap efficiently removes large particles and agglomerates, provides increased surface area, and intensifies cartridge strength, while eliminating residual debris common with conventional, machined resin-bonded cartridges. The filters’ inner layers provide superior smaller-particle removal. Units handle flowrates of 10 gal/min for each 10 in. of cartridge length. Inner layers are available in sizes from 2 to 150 µm, and cartridges are available in sizes up to 40 in. They can withstand pressure surges of up to 150 psid, depending on fluid temperature, and can operate at temperatures up to 250°F. They can remove contaminants from even viscous fluids, such as adhesives, chemical coatings, petroleum products, and paint and printing ink.
