The AirTAC GFR30010MJF1TK 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 GFR30010MJF1TK is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration has a 3/8 in NPT port, manual drain, 40 um standard filter element, an embedded square gauge with MPa scale, and a reverse (check) valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing, and the bowl on the 300 size is polycarbonate (PC). No mounting bracket is included.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, an optional 5 um filter element (code W), gauge scales in MPa, psi or bar, and bracket or no-bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet details 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Clean, regulated air for the cylinder and gripper circuits of a carton-forming and sealing line, with the check valve holding downstream pressure during upstream dips.
Filtered and pressure-regulated supply to vacuum ejectors and pneumatic slides on an assembly cell, with the MPa gauge giving operators a local setpoint reference.
Conditioned air for impact wrenches and inflation tools at a workshop drop, where the manual drain lets staff bleed accumulated water at the end of each shift.
Size and port: the 300 size carries a 3/8 in port, one step up from the 200 series, so match size and port to the flow your line needs - we can confirm flow from the datasheet curves before you order. Drain: this model is manual drain, so an operator opens the bowl drain periodically; automatic and differential-pressure drains are available if you want unattended moisture removal. Filter grade: the standard 40 um element suits general pneumatic supply, with a 5 um element (code W) for finer protection. Gauge: the embedded square gauge here reads MPa; psi or bar scales and an external round gauge are options. Thread: NPT on this model, with PT (the standard) and G (BSPP) available to order. No mounting bracket is fitted; bracketed variants exist. 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 this series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow from the datasheet curves for this 300-size, 3/8 in NPT unit before you order.
The M code means the bowl drain is opened by hand, which suits bays and cells that are checked daily. If the unit sits where nobody drains it regularly, order the automatic drain (code A) or use the differential-pressure drain so condensate is removed without operator attention.
