It uses a coalescing cartridge to filter out 99.9% of oil and particulate, protecting air brakes, suspension, and other pneumatic components. Replace it when the dryer fails to purge, the desiccant becomes saturated, or during routine maintenance (typically every 24 months for standard service). This model requires a 12-volt 100-watt heater and an external purge tank for desiccant regeneration.
