Air travels through the pre-cooler where it is cooled 10 to 15 ° F (-12.2 to -9.4 Celsius) within ambient room temperature. Cool air enters the coalescent filter, which removes 99.9997% of all particulate matter. As the clean air travels through the desiccant tank it is dried to -25°F (-31.7 Celsius) dew point. The clean dry air flows into the main storage tank through a check valve. Some air is directed to the purge tank. As both tanks fill, the pressure switch opens at preset pressure and stops the compressor.

Lack of proper ventilation is the main reason for premature compressors failures. Whenever possible, use exhaust fan to bring cool air from dental office to the equipment room, or run fresh air intake lines to the outside so the compressor can breathe in fresh, outside air. Exhaust the stale, hot air out through the roof or side wall.

When the storage tank is filled to the preset pressure the pressure switch will open and stop the compressor. Exploded views ..................................... E-1 During the Purge Cycle... The pressure switch shuts off current to the compressor head(s) and the solenoid / purge valve. A mechanical valve on the pressure switch opens up to unload the compressor headlines. At the same time the solenoid opens, starting the purge cycle. Cut-In / Cut-Out time Cut-In / Cut-Out is the minimum and maximum discharge pressures at which the compressor will switch from unload to load operation (cut-in) or from load to unload (cut-out). The pressure switch controls Cut-In / Cut-Out times.
