The AirTAC GFR30010MJF2TK AirTAC Filter Regulator NPT3/8 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 PT3/8" 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 GFR30010MJF2TK is an AirTAC GFR300 filter regulator: a 300-size unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has NPT3/8 ports, a manual drain on a polycarbonate bowl, a 40 um standard filter element, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). An embedded square gauge graduated in psi is fitted, and the K code adds a reverse (check) valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The J code means no mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and options include automatic or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, G (BSPP) or NPT threads in place of the PT standard, and mounting brackets. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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 0.05 - 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.

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 filtered, regulated air to the tool-change and clamping circuits on a CNC machining centre, with the fitted check valve holding downstream pressure if the upstream supply dips.
Conditioning the air that drives pick-and-place cylinders and grippers on a packaging conveyor line, where the manual drain suits a shift-start maintenance routine.
A point-of-use filter regulator at an assembly-station air drop, giving operators a local psi gauge and a stable set pressure for hand tools and small actuators.
Choose the size and port step (200 through 600, 1/8 to 1 inch) against the flow your line needs - larger sizes carry larger ports and more flow. On this 300-size unit the drain is manual (code M), so an operator drains the bowl; automatic or differential-pressure drains are available if you prefer unattended draining. The 40 um element is standard; specify W for the 5 um grade where finer filtration is required. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge can be ordered. The T code gives NPT threads; G (BSPP) is also a catalogue option and PT is the standard thread. The J code means no mounting bracket - order one if you bracket-mount. Because flow is published as curves rather than a single rated figure, 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. The reflux valve permits reverse flow 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 a number here. Ask us to confirm the datasheet and check the curve against your required flow at your working pressure before you order.
M is the manual drain: an operator opens the drain at the bottom of the polycarbonate bowl, rather than relying on an automatic or differential-pressure drain. K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply is lost.
