Kaman introduces improved 4-micron fluid filter cart

The Kaman distribution group has introduced the Kaman Filter Cart, a portable filter system for many varieties of industrial fluids, including lubricants, quenching fluids, coolants, synthetic oils, and petroleum-based fluids. The filter cart has the capability to filter out contaminant particles down to 4 microns.

The 16” hard rubber wheels and ruggedized steel frame construction of the Kaman Filter Cart Model 634 allow it to be transported to any stationary apparatus where needed. It can be pushed, pulled or lifted by crane or forklift to almost any machine within an operating environment.

The Kaman filter cart features an industrial-grade 5 GPM internal gear pump, utilizing a “gear within a gear” mechanism: designed more than 70 years ago, this has proven effective for generations in handling a broad range of fluids. True three-tooth engagement between rotor and pinion extends the service life of the pump and allows for pumping of higher-viscosity lubricants and gear oils.

A 30-micron pre-filter and a 4-micron final filter assembly are available as standard equipment on the Kaman Filter Cart. The 30-micron filters collect the larger particles while the 4-micron does the polishing. All filter elements used on the Kaman Filter Carts are a Beta ratio 1000 or greater. The Beta rating, an industry standard way of rating an element's actual performance, is obtained by counting contaminant particles in the inlet oil, then counting the particles in the outlet oil after it passes through the element. The formula for the Beta ratio is the particle count coming in divided by the particle count going out. Beta 1000 means that for every 1000 particles that pass through the element, only one comes out: it removes 999 out 1000 particles (99.9% effective).
