Factors affecting the lifetime of the cartridges are:Oil vapour concentration - The higher the inlet concentration of oil vapour, the faster the activated carbon capacity will expire.Bulk oil - Adsorption filters are designed to remove oil vapour and odours, not liquid oil or aerosols. Poorly maintained or non-existent pre-filtration will cause the OVR filter capacity toquickly expire.Temperature - Oil vapour content increases proportionally to inlet temperature, reducing element life. Additionally, as temperature increases, the adsorption capacity decreases, againreducing element life.Relative Humidity or Dewpoint - Wet air reduces the adsorptive capacity of the carbon.Compressor oil changes - When compressor oil is changed, the new lubricant burns off “light ends” which increases the oil vapour content for hours or even weeksafterwards. This increase in oil vapour content is adsorbed by the OVR filter, significantly reducing its adsorptive life.The cartridge performance is based upon a maximum oil vapour inlet concentration of 0.018mg/m 3, with compressed air at 21 oC and a pressure dewpoint of -40 oC PDP.These cartridges should be replaced upon detection of vapour, odour or taste.MX Dryer Replace / Calibrate dewpoint transmitter (DDS Units only).Recommended ServiceCO Monitor Calibrate the CO MonitorCO Monitor Replace the electrochemical sensorRecommended ServiceCO Safe Replace the Catalyst cartridges (2)(2) Under normal operating conditions the catalyst cartridges should be replaced every 24 months. If an oil vapour incident occurs then we recommend that the carbon and catalystcartridges are replaced at the same time .MX Dryer Replace the valve seats and seals.Recommended ServiceMX Dryer Replace the Desiccant.Recommended ServiceCheck Process Replace |
