BOGE Screw Compressor Oil Filters are high-pressure, precision-engineered cartridges designed to remove metallic wear particles, dirt, and oxidized oil "varnish" from the compressor’s lubrication circuit. In a BOGE rotary screw system (such as the C-Series or S-Series), the injected oil is responsible for lubricating the high-speed bearings, sealing the micro-clearances between the rotors, and absorbing the intense heat of compression. Because BOGE compressors are designed for continuous, heavy-duty industrial use, their oil filters must withstand high operating pressures and aggressive synthetic lubricants (like BOGE Syprem S) without the internal media collapsing or the sealing gaskets failing.
