Product Feature

Most of the AC-A and AC-B features have been incorporated into the AC-D clear bowl shroud for complete visibility; embedded gauges and pressure switches; reduced maintenance space and simplified element replacement for the AF-D series filters.

1. Modular design with uniform body style. Mounting interchangeable with existing product

2. Extended range of pipe adapters, interfaces and modular pressure switches.

3. Easy element replacement. Element and bowl are one piece. Replacement can be done manually.

4. Energy saving regulator. Pressure drop: Max. 50% improvement

5. Reduced maintenance space: Max. 46% reduction

6. Rc, NPT or G threads available.

Order Example:

Option/Semi-standard: Select one each for a to i.

Option/Semi-standard symbol: When more than one specification is required, indicate in alphanumeric order.

ac20b d to ac60b d filter regulator specifications

Drain guide is NPT1/8 (applicable to the AC20-D) and NPT1/4 (applicable to the AC30-D to AC60-D). The auto drain port comes with a Φ3/8″ One-touch fitting (applicable to the AC30-D to AC60-D).
Drain guide is G1/8 (applicable to the AC20-D) and G1/4 (applicable to the AC30-D to AC60-D).
When pressure is not applied, condensate which does not start the auto drain mechanism will be left in the bowl. Releasing the residual condensate before ending operations for the day is recommended.
If the compressor is small [0.75 kW, discharge flow is less than 100 L/min (ANR)], air leakage from the drain cock may occur during the start of operations. N.C. type is recommended.
When the pressure gauge is attached, a 1.0 MPa pressure gauge will be fitted for standard (0.85 MPa) type. 0.4 MPa pressure gauge for 0.2 MPa type.
Pressure can be set higher than the specification pressure in some cases, but use pressure within the specification range.
A bowl guard is provided as standard equipment (polycarbonate).
A bowl guard is provided as standard equipment (nylon).
The combination of float type auto drain C and D is not available.
Without a valve function.
The combination of metal bowl 2 and 8 is not available.
When choosing with W: Air filter drain port, the drain cock of a lubricator will be with barb fittings.
For the pipe thread type: NPT Cannot be used with M: Round type pressure gauge (with color zone). Available by request for special. The digital pressure switch will be equipped with the unit selection function, setting to psi initially.
For options: E1, E2, E3, E4
For the pipe thread type: NPT only
Select with options: E1, E2, E3, E4
