  • Air-Main Charging Valves
Protecting compressed air quality - no overwhelming of the air treatment system
Compressed air treatment systems are designed for a certain rate of air flow which, when the system is operating at full load, pushes against the pressurized air in the air distribution network. However, should this resistance not be present, for example during periods of low load or downtime, it is possible that dryers and filters may be "overwhelmed" by the sudden surge in airflow that occurs when the system re-starts. DHS air-main charging systems reliably prevent this from occurring.
