The AirTAC GFR30010MLJF2WGK AirTAC Filter Regulator G3/8, 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 GFR30010MLJF2WGK is an AirTAC GFR-series filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size-300 configuration has a G3/8 (BSPP) port, a 5 um filter element (the fine option; 40 um is standard), a manual drain on the polycarbonate bowl, and the low-pressure type regulator. A square pressure gauge reading in psi is fitted, a reverse/check valve is built in, and no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options including 40 um or 5 um filtration, manual, automatic or differential-pressure drains, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rating, so ask us to confirm sizing and request 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure 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. |
| 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. |
| G | G (BSPP) 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.

Regulate supply to hot-melt glue heads or coating nozzles that run at low set pressures, with the 5 um element keeping fine metering valves free of particulate and water.
Feed filtered, regulated air to a robotic pick-and-place cell's gripper and valve block; the built-in check valve helps hold the downstream circuit if supply pressure dips.
Point-of-use regulation on a carton-sealing or stretch-wrapping machine line, with the psi gauge for operator checks and a manual drain tied into the maintenance round.
Size and port step with flow: this 300 size carries a 3/8 inch G-thread port; step down to 200 for compact lines or up to 400 and 600 for larger ports and more flow. Drain: the manual drain means an operator opens the bowl drain periodically; choose automatic or differential-pressure draining for unattended installations. Filtration: the fitted 5 um element (code W) suits sensitive directional valves and instruments, while the 40 um standard element covers general plant air. The embedded square gauge reads psi, with MPa or bar scales and an external round gauge as alternatives; the G (BSPP) thread is a catalogue option beside PT and NPT, and this configuration is supplied without a mounting bracket. Because flow is published as curves, not a single rating, 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 GFR-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm sizing from the datasheet on request.
The L code makes this a low-pressure type filter regulator rather than the standard version. Its exact adjustment range is not published in the material we quote, so tell us the set pressure your circuit needs and we will confirm suitability before you order. Everything else decodes normally: G3/8 port, 5 um element, manual drain, psi square gauge and built-in check valve.
