Applications:
Designed for air brake systems in heavy-duty trucks and trailers using the Model HF platform. Integrates a D2-style governor, heated purge, and oil coalescing cartridge for superior moisture and contaminant removal. It removes moisture, oil aerosols, and contaminants from compressed air before it enters the air brake reservoirs. Its integrated 4-port parallel pressure protection valves distribute clean air to primary, secondary, and auxiliary circuits while maintaining system protection. The included non-adjustable governor and heated purge system help maintain reliable operation in severe winter environments common in heavy-duty truck applications.
