The AirTAC GFR30010MLC1WT AirTAC Filter Regulator NPT 3/8 in 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 GFR30010MLC1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration has a 3/8 in NPT port, a 5 um filter element, a manual-drain polycarbonate bowl, the low-pressure regulator type, a round gauge scaled in MPa, and a mounting bracket included. It handles a maximum inlet pressure of 1.0 MPa (145 psi) at media temperatures of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, and standard or low-pressure regulation. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding clean, regulated air to gripper and control-valve circuits on assembly robots, with the 5 um element protecting small pilot valves from particulate and water carryover.
Supplying regulated air to the cylinder-driven tapers, labelers and case erectors on a packaging line, with the manual drain letting maintenance drain the bowl on a fixed schedule.
Conditioning air for spray guns and low-pressure coating setups, where the 5 um element and the low-pressure regulator type keep finish quality consistent at modest set pressures.
Choose the size by port and flow: 200, 300, 400 or 600, with ports from 1/8 to 1 in - this unit sits at 300 with a 3/8 in NPT port. Drain types trade convenience against attention: manual (this unit) needs periodic bowl draining, automatic drains on its own, and the default differential-pressure drain uses the pressure drop across the element. Filter grade is 40 um standard or 5 um (code W) for finer protection - this unit carries the 5 um element. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this one is fitted with a round MPa gauge. Thread is PT as standard with G and NPT as order options, and a bracket is included (code J deletes it). Because flow is published as curves rather than 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. 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 application details and we will confirm the flow from the datasheet and check the sizing against your demand.
The M in the code specifies a manual drain: the polycarbonate bowl is drained periodically by hand. If you prefer hands-off drainage, the same GFR300 filter regulator is available with an automatic or differential-pressure drain - tell us and we will quote the correct suffix.
