By tightening the activating screw, the gas generator drops into the electrolyte fluid where it starts an electrochemical reaction that builds up pressure (up to 4 bar/ 58 psi) and causes the piston to move forward. The lubricant is continuously injected into the lubrication point.

The transparent casing permits easy monitoring of the amount of lubricant discharged. The lubrication period is determined by different color activator screws (1, 3, 6, or 12 months).
