Auto Drain 

The Ultima 500 compressor is equipped with an Auto Drain System. The Auto Drain System automatically purges the air holding tank for 2 seconds for every 30 minutes the power to the unit is on. This feature significantly extends the working life of the compressor preventing rust inside the tank. The fluid from the Auto Drain System will collect in the Collection Bottle that is attached to the inside of the dental unit above the compressor. The Auto Drain Collection Bottle should be emptied and cleaned weekly, at a minimum.
