kn airfilters 33-3106

The 33-3106 air dryer cartridge is a high-quality substitute component engineered for heavy-duty vehicle pneumatic brake systems. It efficiently traps water vapor, oil mist and particulate pollutants carried by compressed air. By drying the air circuit continuously, it avoids pipeline rust, freezing failures and premature damage to brake valves and air chambers. Designed according to original equipment dimension standards, this desiccant cartridge sustains stable drying efficiency amid variable driving loads and extreme ambient conditions. It safeguards brake responsiveness, cuts fleet maintenance costs and reduces sudden roadside malfunctions for long-haul transportation vehicles.
