The AirTAC GFR30010MLJC2T AirTAC Filter Regulator NPT 3/8 in 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 GFR30010MLJC2T is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has a 3/8 in NPT port, the standard 40 um filter element, and a manual drain, so the PC (polycarbonate) bowl is drained by hand as part of routine maintenance. It is the low-pressure regulator type, carries a round pressure gauge scaled in psi, and is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 series is also available in other port sizes and thread options (PT standard; G and NPT to order), with automatic or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges in MPa, psi or bar scales, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures for your application on request.

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). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |
| (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.

Mounted ahead of carton sealers and case erectors on a packaging line, it strips water and debris from shop air and lets maintenance set a steady, low supply pressure to the sealing cylinders, read directly on the psi gauge.
Installed at the air drop feeding sorting gates and conveyor diverters, it cleans the supply and gives operators a local point to regulate and check working pressure without walking back to the main FRL.
Feeding a paint spray gun line in a finishing booth, the 40 um element catches water and particulate while the low-pressure regulator keeps gun supply pressure gentle and repeatable between shifts.
Everything on this unit is decodable from the code: size 300 with a 3/8 in NPT port; drain type (this unit is manual; automatic and differential-pressure drains are available); filter grade (40 um standard, 5 um with code W); gauge style and scale (this unit carries a round psi gauge; embedded square gauges in MPa, psi or bar scales are the standard alternative); thread (PT is the standard, G and NPT are order options); and bracket (this unit is supplied without a bracket). The L in the code marks the low-pressure regulator type. Step up through the 200/300/400/600 sizes against the flow your line needs. Because flow is published as curves rather than a single rating, send us your application details 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 series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures on request before you order.
The L in the code marks the low-pressure regulator variant of the GFR300 series. The exact adjustment range for this variant is not published in the material we hold, so ask us to confirm it on request. Note also that the M in the code means the bowl is drained by hand; automatic and differential-pressure drains are available as alternative codes.
