The AirTAC GFR300C15JC2WG AirTAC Filter Regulator G1/2, 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 AirTAC GFR300C15JC2WG is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is sized GFR300 with a G1/2 (BSPP) port, carries the 5 um filter element (code W) for finer filtration than the standard 40 um, and drains its polycarbonate bowl by differential pressure, which bleeds collected moisture automatically as air flows through. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), an external round gauge reads the downstream pressure in psi, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and no reverse/check valve or mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 inch, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and an optional bracket; G and NPT threads are catalogue options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.15 - 0.9 MPa (20 - 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.

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.

Point-of-use filter regulation for a CNC machining cell: the 5 um element helps protect solenoid valves on the machining centre while the regulator holds a steady setpoint to the tool-change and clamping circuits.
Feeding the pneumatic cylinders and grippers on a carton-forming packaging line, where clean, moisture-managed, pressure-stable air keeps seal jaws and product-push actuators cycling consistently.
Regulated air for diverters and stop-gates on a distribution-centre conveyor line; the differential-pressure drain keeps the bowl clear without manual attention across long shifts.
Choose the size step (200/300/400/600) and port against the flow your line needs - the larger the size, the larger the port and flow capacity; we will confirm exact figures from the curve data on request. This unit already carries the 5 um element; the standard 40 um suits general shop air, while 5 um better protects sensitive valves and instruments. Drain options are differential-pressure (fitted here), automatic, or manual - manual-drain versions also widen the regulation range to 0.05-0.9 MPa (7-130 psi). Gauge scale (MPa, psi or bar), thread (PT standard, with G or NPT to order) and bracket are all selectable; this configuration comes with a round psi gauge and no bracket.
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 as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request.
The W code fits the 5 um element in place of the standard 40 um, for finer protection of downstream valves and instruments, and the C2 code adds an external round gauge reading in psi. Both are orderable differently - 40 um element, square embedded gauge, MPa or bar scale - on request.
