Air Carving Turbine With 3 Extra Rotors Model: SH300（ 3 R890 Rotors） Compatible with Bien Air TD783 Carv-Air Turbine *Connection: air tube connect directly or 4-hole handpiece tube (Figure 1). * Working Pressure: 3.0MPa-3.5MPa * Recommended Working Speed: 320,000 rpm * Weight: about 92 grams * Air Consumption: average 35 L/min. * Cooling Air (SH300S): 2 L/min (0.20MPa) * Water spray (SH300S): 100 ml/min (0.20MPa) * Using without an air controller: Use a pressure gauge to check and adjust the air pressure on the entering of the handpiece. Pressure adjust at 0.28MPa when the handpiece is running. * Using with an air controller: * Step on the foot pedal and adjust the air pressure to 3.2MPa when the handpiece is running. Warning: Air pressure should no more than 4.0MPa, otherwise the bearings will be damaged quickly.
