Remarks
  1. COA has a timer that controls its operation and interval time. The control box has a built-in buzzer that sends an alarm when the oil level is low. The control box also has four indicators, operation (ACT), alarm (ALM), immediate lubrication (RUN), and interval (INT).
  2. COA has to work with CO, OA, or OC type oil-air volume distributors to deliver the metered quantity of oil-air mixture to the lubrication points.
  3. COA can memorize the set value of operation time and interval time.
  4. COA has a pressure gauge that enables the user to check the operating pressure easily.
  5. COA has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
  6. COA has a pressure-regulating valve that enables the user to adjust the operating pressure.
  7. COA has a feed-oil button (F button), which can be used as manual oil feeding for less than 3 minutes to avoid overloading the motor.
  8. COA has an 8kgf/ cm2 NC contact socket pressure switch that detects the operating pressure.
  9. The gear pump of COA is made of special aluminum alloy and assembled with the induction motor to provide stable output pressure, low operating noise, and long service life. It meets the requirements of most large machines.
