How to select the right Baosi one-stage airend
The Baosi one-stage range runs from the small belt-driven YNT46 up to the large direct-driven YNE226. The table above lists every model at 0.7, 0.8, 1.0, 1.25, 1.5 and 1.7 MPa, because capacity falls as pressure rises — two machines with the same motor can use different airends.
- Small sizes — YNT46 / YNT46A (belt drive, up to about 8 kW), YNT55A and YNT60A for 7.5–11 kW, YNT70A / 70B for 11–22 kW, YNT80A for 18.5 kW.
- Large sizes — YNE117RA through YNE143RB (22–45 kW) and YNE163RA to YNE226B (45–110 kW and above), all direct driven at 1480–2200 rpm depending on the model.
- Rule of thumb — for the same motor power, a higher working pressure needs a smaller airend. A 20 HP machine at 8 bar and the same 20 HP at 16 bar do not share an airend.
- Selection — read the capacity at your working pressure, then check the shaft power at that point against the motor. Do not size on the 0.7 MPa column if you run at 1.0 MPa.
Installation and maintenance
- Belt-driven models: the pulley ratio belongs to the model. Changing it to gain flow overspeeds the rotor and voids the bearing life.
- Direct-driven models: check the coupling alignment after the first 100 hours and again after the first oil change.
- Keep the oil injection rate and the oil temperature in range — the tables list the injection rate per model, and starving an airend shows up as a temperature rise long before it fails.
- Start unloaded, particularly below 10 °C ambient, so that oil reaches the bearings before load arrives.
Baosi one-stage airend FAQ
Why are there two models for the same power, for example YNT70A and YNT70B?
They are different displacements for different pressure duties. The A version is normally the 8 bar choice and the B version the 10–16 bar choice; compare the capacity columns before deciding.
Can I use a 1.7 MPa airend at 8 bar?
Yes, and you will get more flow at the lower pressure. The reverse is not true: an 0.8 MPa airend run at 1.5 MPa loses flow and overloads the motor.
Do you supply the airend with the pulley, coupling and brackets?
The bare airend is standard; pulley, coupling and mounting brackets can be quoted with it so the assembly matches the machine.
