Service kit K1031 renews the fan assembly of the Jun-Air 120R pump. At 100 percent duty cycle pump life depends directly on cooling, and a tired or blocked fan quickly leads to thermal shutdown.
Fan Service Kit for 120R Compressor Pump - Jun-Air K1031
- This Item: €200.45
- Jun-Air Pressure Regulator for Cabinet Mounting 10 bar – 4071020 €106.40
- Jun-Air Service Kit Minor Service for M6 – 5472014 €221.35
The 120R is built for continuous duty and rejects all of its waste heat through forced cooling. Once the fan slows from bearing wear or the impeller loads with dust, pump temperature rises, delivered volume drops and in the worst case the thermal protector cuts in. The genuine K1031 service kit returns cooling to its design condition.
Benefits
- Secures cooling capacity at 100 percent duty cycle and protects against thermal shutdown in continuous operation
- Lower operating temperature extends the life of piston rings, valve plates and the capacitor
- Genuine Jun-Air part with factory airflow, not a universal replacement fan
- Supplied as an assembly, so mounting and connection fit without modification

Application
A clearly audible fan noise, visible pulsing of the airflow or an unusually hot pump cover are the typical signs. Dust builds up faster inside closed cabinet units, so a visual check at every service pays off there.
