The AirTAC GFR30015MJF2WT AirTAC Filter Regulator NPT1/2, 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 GFR300 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This unit is built on the 300 size with 1/2 in NPT threads, a 5 um filter element (code W), a manual drain on the PC bowl, and an embedded square gauge reading in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is fitted (code J) and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include 40 um or 5 um filtration, automatic, manual or differential-pressure drains, MPa, psi or bar gauge scales, and G, NPT or PT threads. Flow 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeding tool-clamp and tool-change actuators on a machining center: the 5 um element screens condensate and fine particulate away from directional valves, while the regulator holds a steady clamp pressure at the machine drop.
Supplying the pusher and flap-fold cylinders on a carton sealer, where the manual drain suits a shift-start check at the machine and the psi gauge lets operators set and verify line pressure at a glance.
Conditioning air at the drop feeding gripper valves on a pick-and-place robot: filtered, regulated air keeps grip pressure repeatable and protects the compact valves mounted on the robot arm.
Choose the size by the port step and the air your line needs: size 200 covers 1/8-1/4 in ports, 300 covers 3/8-1/2 in, 400 covers 3/4 in and 600 covers 1 in, with the larger sizes moving more air. Drain type is a real decision: a manual drain needs an operator to bleed the bowl, an automatic drain discharges condensate on its own, and the differential-pressure default drains only when the pressure drop is high enough. Filtration is 40 um standard or 5 um with the W code for finer protection of downstream valves. Gauge scale (MPa, psi or bar), thread finish (PT is the standard; G and NPT are order options) and the bracket option are all set in the code. Flow is published as curves, not a single rating, so 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, not a single rated number, so we do not quote a figure here. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
This unit carries code M, a manual drain: an operator opens the drain to bleed collected condensate from the PC bowl, which suits machines checked at shift start. If the installation runs unattended, order the same GFR300 size with an automatic drain (code A) instead. The regulator range on this manual-drain unit is 0.05-0.9 MPa (7-130 psi).
