A Replace AF30/40-A and AF30/40-D series air filter bowl assemblies in the following manner.
① Remove the bowl assembly by pushing the lock button on the bowl assembly down and rotating the bowl assembly 30° to either the right or the left. Then, remove the bowl assembly.
② Mount the new bowl assembly by aligning the marks on the body with the marks on the bowl assembly and inserting the bowl assembly into the body.
Then, rotate the bowl assembly 30゜ (until the lock button pops up) to either the right or the left. Make sure that the lock button is raised and locked at this time.
Note 1) Old AF30/40 and AF3000/4000 series air filter bowl assemblies can be removed/mounted by rotating the bowl assembly 45° to either the right or the left.
Note 2) For AF10/20 series air filter bowl assemblies, remove the bowl assembly by turning it counterclockwise.

A Set the pressure using the knob by moving it in the upward direction while checking the pressure indicated on the pressure gauge (outlet side).
After setting the pressure, be sure to lock the knob.
Moving the knob in the downward direction may cause the pressure to drop below the initial setting.
The knob rotates clockwise to increase pressure and counterclockwise to decrease pressure.
The setting range of the outlet pressure is 85% or less of the inlet pressure. Setting above 85% will leave the product susceptible to fluctuations in flow rate and inlet pressure, and operation may become unstable.
The pressure of the regulator decreases when air is consumed on the downstream side, but it returns to the set pressure when consumption stops.
Refer to the “Flow Rate Characteristics” graphs in the AR series catalog to calculate how much the outlet pressure will drop from the set pressure.
-
A When the power is turned OFF when in a control state, both the built-in solenoid valves for air supply and exhaust are closed. As a result, the pressure in the pilot chamber is maintained, so the outlet pressure is also able to be maintained at a pressure near the set pressure. However, there is always internal leakage present with ITV series regulators, so the retention is temporary and cannot be guaranteed.

A Yes, it is possible. Insert the regulator body and the hexagon panel nut into the panel mounting hole (ø10.5 mm for IR1000 series regulators and ø12.5 mm for IR2000/3000 series regulators) and retighten the shaft of the pressure adjustment knob.
For new IR-A series regulators, select option “H” (With hexagon panel nut (for panel mount)).
(e.g., IR1000-01H-A) The hexagon panel nut is shipped together with the product but does not come assembled.

A If you order the gauge nut assembly, an Rc1/8 fitting can be mounted.

A Their usage depends on the load.
The 2-wire type has a large leakage current, and there are cases where the switch OFF state cannot be recognized when used in combination with a PLC.
The 3-wire type has separate power supply and signal lines, and NPN or PNP output must be selected according to the input specifications.
Leakage current:
3-wire type: 100 μA or less for 24 VDC Ex.) D-M9N
2-wire type: 0.8 mA or less for 24 VDC Ex.) D-M9B(W)
How do I use 2-wire and 3-wire solid state auto switches?
-
A Turn the adjustment knob clockwise to increase pressure or counterclockwise to decrease, using a pressure gauge for verification.
Once set, secure the knob with the locking ring (if equipped) to prevent accidental changes during operation.

A Cleanliness: Flush pipelines with compressed air to remove debris before connecting components.
Orientation: Install filters/regulators in the direction of airflow (follow arrow marks); mount regulators vertically for optimal diaphragm performance (unless specified otherwise).
Torque: Use a torque wrench to avoid over-tightening (e.g., 12–18 N·m for G1/4 threads) and damaging threads.
