JSG-79 micro air pump

Customization Range: Flow 40–50L/min, Pressure 5–7bar, Vacuum -85kPa, Power 50–70W

🔧 Construction Principle

The JSG-79 series miniature piston pump uses a brushed DC motor to drive a piston through an eccentric mechanism. As the piston moves back and forth inside the cylinder, it draws in and compresses air, generating positive pressure or vacuum depending on the pump configuration.
