The AirTAC GFR30010MLC1T AirTAC Filter Regulator 3/8in NPT 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 GFR30010MLC1T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure in the low-pressure type configuration. This unit is built with a 3/8 in NPT port, a manual drain on the bowl, a round pressure gauge scaled in MPa, and a mounting bracket included.
This is a genuine AirTAC part from the GFR300 series. The GFR line is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as options), drain types, filter grades and gauges. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |
| (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.

Feeding clean, regulated air to the cylinders and actuators on a carton-sealing or wrapping line, with the manual drain emptied during scheduled changeovers.
Supplying filtered air at a controlled low pressure to a clamping or holding fixture on a machining cell, where the low-pressure type regulation suits circuits that must not run at full line pressure.
Conditioning the air supply for blow-off nozzles and pneumatic guide rollers on a conveyor line, keeping water and debris out of the nozzles while holding a steady set pressure.
Start with the port step: this unit is the 300 size with a 3/8 in NPT port, so match it to your line size and the flow your circuit needs. The manual drain here means an operator opens the drain to expel collected water - choose the automatic or differential-pressure drain variant instead if the unit is mounted where regular draining is impractical. The 40 um element is the standard grade; specify the W variant if you need 5 um filtration. The round gauge fitted here reads in MPa; square embedded gauges and psi or bar scales are also available. PT is the standard thread, with G and NPT as order options, and a bracket is included. Flow is published as curves, not a single rating, so 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your circuit needs and we will confirm the correct size from the datasheet on request before you order.
The M in the code GFR30010MLC1T selects the manual drain: collected water stays in the polycarbonate bowl until an operator opens the drain valve. It suits accessible mounting points with a regular maintenance routine. If the unit will sit where nobody drains it, ask about the automatic or differential-pressure drain variants of the same GFR300 size.
