The AirTAC GFR30015MC2WG AirTAC Filter Regulator G1/2, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015MC2WG is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This unit is built on the 300 size with a G1/2 (BSPP) port, a manual-drain bowl in polycarbonate, a 5 um filter element for finer filtration than the standard 40 um grade, and a round pressure gauge reading in psi. With the manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| C | Gauge shape: Round. C is round, F is square. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtered, regulated air at a set pressure feeds the pneumatic clamps that hold parts in a CNC lathe, with the 5 um element protecting the clamp valve from fine contamination.
On a parcel-sort conveyor, the unit supplies clean air at a fixed pressure to the diverter-arm cylinders so gates throw consistently through the shift.
On a bottling line, the filter regulator conditions the air driving bottle-gate actuators, and the manual drain lets an operator bleed accumulated water at each shift check.
Choose the size and port against the air your circuit needs: the 300 size with its G1/2 port sits mid-range in the GFR line, one step above the 200 and below the 400 and 600. This code fixes a manual drain - you open the bowl valve yourself, which suits positions checked routinely; automatic or differential-pressure drain codes suit units that are hard to reach. The 5 um (W) element gives finer filtration than the 40 um standard. The round gauge here reads in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP); PT is the standard thread and NPT is orderable. A mounting bracket is included. Flow is published as curves, not a single rating, so send us your flow requirement and we will confirm sizing from the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves rather than a single rated figure, so there is no one number we can quote. Tell us your flow requirement and port size and we will confirm the datasheet curve figures for this exact unit on request.
M in the code means a manual drain: an operator opens the bowl valve to release collected water, which suits units mounted where they are checked routinely. The same GFR300 size is also catalogued with automatic or differential-pressure drains if you would rather not rely on manual checks.
