The AirTAC GFR30010MLC2T AirTAC Filter Regulator NPT 3/8 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 GFR30010MLC2T is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration has a 3/8 in NPT thread, a 40 um filter element, a manual drain on the polycarbonate bowl, and a low-pressure regulator fitted with an external round gauge scaled in psi. A mounting bracket is included, and the transparent bowl lets you check condensate and element condition at a glance. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, an optional 5 um element (code W), automatic or manual drains, G (BSPP) or NPT threads in place of the PT standard, and gauge and scale choices. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. |
| (blank) | Mounting bracket included. |
| (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 at the air drop for a carton-sealing or case-packing machine, it strips water and debris from the shop air and holds a steady, reduced pressure to the cylinders driving the sealing heads. The manual drain suits a line where an operator bleeds the bowl during shift checks.
Fitted ahead of the clamping circuit on a CNC fixture, it delivers cleaned air at a stable reduced setting so workpiece clamps hold consistently through the cycle. The included bracket fixes the unit to the cell panel, and the round psi gauge gives a direct local reading.
Installed on the supply to diverter and pusher gates on a sortation conveyor, it removes condensate carried over from the compressor room and regulates pressure to the gating cylinders. The transparent bowl makes it easy to spot water loading during walk-round inspections.
The real choices in this family are the size and port step (200/300/400/600, 1/8 to 1 inch) against the flow your line needs; the drain type (differential-pressure standard, automatic code A, manual code M); the filter grade (40 um standard, 5 um with W); the gauge (embedded square standard, external round optional, in MPa, psi or bar scales); and the thread (PT standard, G or NPT to order). This unit is the low-pressure regulator type with a round psi gauge, NPT 3/8 port, 40 um element and manual drain. Flow is published as curves, not a single rated figure, so 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Send us your inlet pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request.
The M in the code means the bowl drain is opened by hand, which suits installations where collected condensate can be bled as part of a routine. If you want the bowl to discharge on its own, order the A suffix for an automatic drain; the blank code is the differential-pressure drain. We can help you pick the right drain for your duty on request.
