SMC AWD30-N02DE-Z Micro Mist Separator Regulator, Size 30, 1/4" NPT, 0.01 Micron

The SMC AWD30-N02DE-Z is a size 30 micro mist separator regulator from SMC's AWD20-40 series. It combines a 0.01 micron micro mist separator and a pressure regulator in one modular body, delivering clean, oil-mist-free compressed air at a set pressure without the piping and footprint of two separate units. This configuration is built with 1/4" NPT ports, a float-type auto drain, and a square embedded pressure gauge.

What a micro mist separator regulator does

Standard air filters capture particulate and bulk liquid down to roughly 5 micron, and mist separators reach about 0.3 micron. A micro mist separator goes further, coalescing sub-micron oil aerosol down to 0.01 micron - the fine oil mist that ordinary filtration passes straight through. Pairing that with an integrated regulator means the AWD30-N02DE-Z both cleans the air and holds it at a stable downstream pressure, which is why it is used ahead of equipment that is sensitive to oil carryover.

Typical applications

• Air blow-off and air bearings where residual oil would contaminate the work or surface
• Precision instruments, pneumatic gauging, and analytical equipment
• Paint and coating lines sensitive to oil carryover
• Electronics, food, and packaging processes requiring clean regulated air in a compact footprint

How this part number is configured

SMC builds the AWD20-40 series from a configurable part number. The AWD30-N02DE-Z breaks down as: AWD micro mist separator regulator, body size 30, N NPT thread, 02 1/4" port, D float-type auto drain (normally open), E square embedded pressure gauge, with the Z semi-standard package (drain cock, relieving type, left-to-right flow, name plate, and imperial-unit gauge in psi and degrees F). The standard setting range is 0.05 to 0.85 MPa with a polycarbonate bowl.

Specifications

Maintenance parts and replacement

To keep an installed AWD30 running, the matching micro mist element is the AFD30P-060AS element assembly, and routine service parts are bundled in the KT-AWD30-02 maintenance kit. For new installations, SMC directs designers to the current AWD-D series as the direct replacement for the AWD20-40 line.

Frequently asked questions

What is the SMC AWD30-N02DE-Z?

It is a size 30 micro mist separator regulator from SMC's AWD20-40 series. It combines a 0.01 micron micro mist separator with a pressure regulator in one modular unit, configured with 1/4" NPT ports, a float-type auto drain, and a square embedded pressure gauge.

Is the AWD30-N02DE-Z still made?

No. SMC discontinued the AWD20-40 series in March 2025 and replaced it with the AWD-D series. Automation Distribution still supports the legacy AWD line for maintenance and exact-replacement needs - contact us for current availability or an AWD-D equivalent.

What does the 0.01 micron rating mean?

It is the micro mist separation grade - the unit coalesces sub-micron oil aerosol down to 0.01 micron, far finer than the 5 micron of a standard filter or the 0.3 micron of a mist separator, for applications that cannot tolerate oil carryover.

What is its pressure setting range?

The standard setting range is 0.05 to 0.85 MPa, roughly 7 to 123 psi, with a relieving-type regulator and polycarbonate bowl.
