The AirTAC GFR300C15MLJF2WGK 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.
GFR300C15MLJF2WGK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air down to 5 um and regulates downstream pressure. This configuration carries G1/2 ports, a manual drain, the low-pressure regulator type, an embedded square gauge reading in psi, and a built-in reverse/check valve; it is supplied without a mounting bracket. The bowl is metal, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm the sizing and datasheet figures on request.

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.

A filtered, regulated supply for panel-mounted valves and pilot circuits that run at low setpoints, with the square psi gauge giving a direct local reading and the built-in check valve blocking reverse flow through the unit.
Feeding clean, regulated air to the cylinders and air valves on a cartoner or case packer; the 5 um element strips water and fine particulate before they reach valve seats, and the manual drain is bled during routine shift checks.
A compact filter-regulator point for lab benches and test rigs where instruments need low-pressure air; the metal bowl and psi gauge suit a bench panel, and the G1/2 ports tie straight into the main drop.
The real choices in this family are the size and port step against the air demand of your circuit, the drain type (manual here; automatic and differential-pressure are alternatives), the filter grade (5 um on this unit versus the 40 um standard), the gauge scale (this one reads psi; MPa and bar are available), and the thread (PT is the standard; G and NPT are order options - this code is G). Brackets are optional and this configuration omits it. Because this is the low-pressure (L) type, confirm your setpoint with us before ordering - the exact range for this variant is not published. Flow is published as curves, not a single rating, so ask us to check the curve against your application 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 this family as curves rather than a single rated figure, so we do not quote a number. Send us your port size, working pressure and air demand and we will confirm the sizing from the datasheet on request.
This unit is the L low-pressure type, and the exact setpoint range for this variant is not published in the material we hold - we confirm it on request before you order. The manual drain means accumulated water is bled from the metal bowl at regular intervals; automatic and differential-pressure drains are available elsewhere in the family if you prefer hands-off drainage.
