The AirTAC GFR300C10MJF2WK AirTAC Filter Regulator 3/8 in PT 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 GFR300C10MJF2WK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This configuration is a 3/8 in PT port unit with a 5 um filter element, a metal bowl with a manual drain, an embedded square gauge scaled in psi, and a built-in check valve that lets air pass on reverse flow. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR300 size sits in a series that runs from 200 to 600 with ports from 1/8 to 1 in, and orderable options include automatic or differential-pressure drains, the 40 um standard element, gauge scales in MPa, psi or bar, an external round gauge, and G or NPT threads in place of PT. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Filtering and regulating the air feed to a pneumatic clamp or fixture on a CNC machining cell, where the 5 um element protects the directional valves from water and particulate and the regulator holds a steady clamping pressure.
Conditioning the air feeding the pick-and-place and pusher cylinders on a packaging conveyor, giving one filtered, regulated supply point at the line with a psi gauge the maintenance team can read at a glance.
Filtering and regulating the air supply to a paint spray booth, where the 5 um element cleans the air at the point of use and the manual drain lets an operator drain accumulated water from the metal bowl at the end of each shift.
Size the unit by port and flow: this is size 300 with a 3/8 in PT port, and larger sizes in the series carry more flow. Because flow is published as curves and not as a single rating, send us your air demand and we will confirm sizing against the datasheet before you order. This code already carries a manual drain, a 5 um element, a psi-scaled square gauge and a reverse check valve; if you would prefer automatic or differential-pressure draining, the 40 um standard element, an MPa or bar gauge scale, a G or NPT thread, or a mounting bracket, those are orderable choices within the same GFR300 series.
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.
Flow for the GFR300 series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - port size, downstream demand and line pressure - and we will confirm the datasheet flow curve and correct sizing before you order.
This configuration carries code M: a manual drain, meaning someone drains the bowl by hand, which suits attended installations and shift-end routines. If the unit will run unattended, the same GFR300 series is available with an automatic drain (code A) or a differential-pressure drain (the default). Ask us to quote the alternative code.
