Filter Cartridges
Unique Design Provides Safer Filtration of
Hazardous Fluids
• Disposable filter cartridge/plastic housing element
• Virtually eliminates operator contact with fluid during
changeover
• A wide variety of depth or pleated media filter cartridges
available
• Available in retention ratings from 0.2 to 100 microns
(µm)
• Economical alternative to expensive competitive
capsules
• 1⁄4", 1⁄2", 3⁄4" or 1" NPT inlet and outlet connections
available for use in most piping plans
• 1⁄4" vent allows the housing assembly to be easily vented
or drained

- CAUTION! Gas applications are inherently more hazardous than liquid
service and strict adherence to the maximum recommended
pressure/temperature is required.

- Polypropylene wafer, mixed with a small amount of 400 series stainless
steel, is electromagnetically heated. This process assures an excellent
bond between the polypropylene head and polypropylene shell.
