The AirTAC GFR300C15JF2WGK 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 GFR300C15JF2WGK is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubricator. This size 300 unit is threaded G1/2 (1/2 in), carries the 5 um filter element (the W grade, finer than the 40 um standard), drains by differential pressure, and has the embedded square gauge fitted, reading in psi. The K option adds a reverse-flow check valve, and the J suffix means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing. The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR300 family is offered with a choice of drain (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar, with an external round gauge as an alternative to the embedded square type), thread (PT is the catalogue standard, with G and NPT as order options) and bracket. Flow for GFR units 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.

Filtered, regulated supply to the directional valves and cylinders that index and stop product on a packaging conveyor, with the 5 um element guarding the valve spools from finer contamination.
Regulated air to the clamping cylinders and swing clamps on a CNC machining fixture, where a locally set downstream pressure keeps holding force consistent through the cycle and the check valve blocks reverse flow through the unit.
Point-of-use filter regulation at a machine drop on an assembly line, combining water and particle removal with a working pressure set locally for the actuators and air tools fed from that station.
Choose the size and port against the air your equipment actually consumes: size 300 with a 1/2 in port sits mid-range in the GFR family, with size 400 as the next step up. Pick the drain to suit the installation: differential-pressure (this unit) drains automatically as flow passes, automatic (A) drains on its own cycle, and manual (M) needs someone to operate it. This unit carries the 5 um element (code W) where downstream valves and instruments need finer air than the 40 um standard. The gauge here is the embedded square type reading psi; MPa and bar scales are alternatives. Thread is G (BSPP) on this unit; PT is the catalogue standard and NPT is also orderable. A bracket is optional and this configuration has none. 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your working pressure and the air consumption of the equipment you are feeding, and we will confirm the flow figures and the datasheet for this exact model on request.
This unit carries the W option: a 5 um element that removes finer particles than the 40 um standard grade, which is the usual choice upstream of directional valves, instruments and other sensitive components. If your supply is already well filtered or the downstream equipment tolerates coarser air, the 40 um standard grade is the simpler choice. Drain type, gauge scale and thread can also be specified differently - ask us to decode the exact option set you need.
