We utilize Ultraviolet, Ozone, Carbon Filtration, and HEPA and ULPA filtration, to provide disinfection solutions for the markets above. Ultraviolet is a proven technology for disinfection, and additional technologies are used as required for the specific application. Air Disinfection Systems.

Industrial Hose AssembliesSpun Bonded Cartridge Filters

Spun - Bonded Cartridge Filters are the depth cartridge filter of choice. they are relatively recent development in prefilter cartridge and primary filter cartridge design. Made from 100% polypropylene fibers, they provide excellent chemical resistance and are very inert in water. With and without center cores, they can handle temperatures of up to 200 degrees in non high differential pressure applications.

They have become the dominant workhorse in the cartridge filter field.
