The AirTAC GFR30010MJC2W AirTAC Filter Regulator PT3/8, 5 um is a genuine G-series filter regulator: water separation, 5 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 AirTAC GFR30010MJC2W is a filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single body. This configuration is the 300 size with a PT3/8 port, a 5 um filter element (code W), a manual drain on a polycarbonate bowl, and a round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the range include automatic, manual or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow for this size is published as curves rather than a single rating, 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 0.05 - 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 a CNC machine's fixture-clamping circuit, where the 5 um element helps keep clamping valves clean and the regulator holds a steady clamp pressure.
Air preparation for cylinders and diverters along a packaging conveyor, keeping moisture and debris out of directional valves while holding the set line pressure.
Supply air for pick-and-place grippers on an assembly line, with the round psi gauge letting operators check and verify the set pressure at the cell.
Size and port step up together: 200, 300, 400 and 600 cover ports from 1/8 to 1 inch, so match this 300 size and its PT3/8 port to your piping and air demand. Drain type is a real choice: this unit has a manual drain, which suits attended installations where the bowl is bled on a routine; automatic or differential-pressure drain versions of the same size suit unattended or inaccessible spots. The 5 um element (code W) is the finer option against the 40 um standard. The round gauge here reads psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is PT as standard, with G (BSPP) and NPT orderable as specifications, and no mounting bracket is included in this configuration. Flow is published as curves, not a single rating, so send us your demand and we will confirm sizing against the datasheet 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 the GFR300 as curves rather than a single rated figure, so we do not quote a number here. Send us your air demand and working pressure and we will confirm the datasheet curve and sizing for your application before you order.
This configuration has a manual drain: condensate collected in the polycarbonate bowl is released by hand, which suits attended installations checked on a routine. If the unit will sit in an inaccessible position, ask us about the automatic or differential-pressure drain versions of the same GFR300 size.
