The AirTAC GFR40015LC2WG 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR40015LC2WG is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is built on the size-400 body with a G1/2 (BSPP) port, a 5 um filter element, and a differential-pressure bowl drain. The regulator is the low-pressure type, and a round gauge scaled in psi is fitted so the setting can be read directly. The bowl on this size is polycarbonate, and a mounting bracket is included. Operating temperature is -5 to 70 C (non-freezing), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and offers drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge and thread options, and standard or low-pressure regulation. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Feeds and regulates the air to fixture clamps on a CNC cell, filtering water and chips-laden particulate out of the shop air before it reaches the clamp cylinders, with the psi-scaled gauge letting the setter read the clamp pressure directly.
Conditions the air feeding spray guns in a finishing booth: the 5 um element strips water and fine particulate that would otherwise blemish the finish, while the low-pressure regulator holds a gentle, repeatable gun supply pressure.
Sits at the drop ahead of the directional valves on a packaging cartoner, cleaning and regulating the air that strokes the box-forming and flap-folding cylinders so the machine cycles consistently shift after shift.
Choose a GFR filter regulator when one body must both clean the air and hold downstream pressure. Step through sizes 200, 300, 400 and 600 and the matching port (1/8 to 1 inch) against the flow your line needs; this model sits at size 400 with a G1/2 port. Drain options are differential-pressure (fitted here), automatic and manual. Filter grade is 40 um standard or 5 um (code W, fitted here) for finer protection of downstream equipment. Gauge scales are available in MPa, psi or bar; threads come as PT standard with G and NPT as order options; a bracket is included on this unit. Because rated flow is published only as curves, ask us to confirm sizing against your application before ordering.
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 GFR series as curves rather than a single rated figure, so we do not quote a number. Tell us your line's flow and pressure and we will confirm sizing from the datasheet on request.
It marks the low-pressure regulator type. The exact adjustment range for the low-pressure version is not published in our data, so we confirm it on request; the maximum inlet pressure remains 1.0 MPa (145 psi) and the unit carries the 5 um element and differential-pressure drain decoded from the rest of the code.
