Philadelphia Gear Corp. announced the availability of two versions of the company's proprietary CORE Continuous Oil Rescue Equipment. Launched as an alternative to traditional barrier filtration techniques, the CORE models filter metallic particles as small as one micron. According to Philadelphia Gear's press release, these filters are now designed to fit lubrication systems ranging from 0.5?2" in diameter, providing protection for critical rotating equipment not previously available. Carl Rapp, CEO of Philadelphia Gear says, "With a magnetic half-life of 50 years, each CORE unit is effectively projected to outlive virtually any machine you put it on," said Rapp. The larger unit, designed for lubrication systems between 1.25?2.0" in diameter, weighs approximately 20 lbs. and holds more than 2 lbs. of debris. The smaller unit, designed for lubrication systems between 0.5' and 1.25", weighs approximately 5 lbs. and holds nearly 1 lb. of debris before cleaning is necessary. Both CORE versions hold more contaminant than a conventional filter because of their three-dimensional storage capacity. This increased capacity also allows for longer periods of operation without service. Inside the cast aluminum housing is an assembly of five magnets, each surrounded by a set of steel flux plates. A series of collection zones are machined into the plates such that oil flow is never restricted, even as debris begins to build up inside the filter. Additionally, the units are sized?even in contaminated situations?to require a routine cleaning is once a year, which can be accomplished by blowing air across the inside. The units can be installed in duplex configurations so that they can be changed out or cleaned without ever shutting down the gearbox itself. One particular feature of the CORE is that is has virtually no pressure drop and therefore is suitable for installing upstream of pumps for additional protection.
