The AirTAC GFR30010MLC2G AirTAC Filter Regulator G3/8, Low-Pressure 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 AirTAC GFR30010MLC2G is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit is fitted with a G3/8 port, a manual-drain polycarbonate bowl, a 40 um filter element and the low-pressure regulator type. A round gauge with a psi scale is fitted, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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. |
| 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. |
| G | G (BSPP) 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.

Supplies filtered, regulated air to pneumatic clamps on a machining fixture where the setpoint must sit below the standard regulator range, with the 40 um element protecting the clamp valve from water and swarf-carrying air.
Feeds filter-regulated air to the small cylinders and air jaws on a carton-sealing conveyor, with the manual-drain bowl emptied during scheduled line cleaning and the fitted psi gauge giving operators a local setpoint readout.
Conditions the air feed to spray guns and coating nozzles on a finishing line, removing water and particulate before the material reaches the tip while the low-pressure type holds the gentle atomising pressure the process calls for.
Choose the size and port step (200/300/400/600, 1/8 to 1 inch) against the flow your line needs - the 300 size with its G3/8 port sits mid-range. This unit has a manual drain, so the bowl is emptied by hand; automatic or differential-pressure drains suit unattended installations. The 40 um element is the standard grade; specify code W for 5 um where finer filtration is needed. The L in the code marks the low-pressure regulator type - its exact range is not published, so confirm your setpoint with us. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are selectable, and the bracket is included on this model. Because flow is published as curves rather than a single rated figure, 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing from the datasheet before you order.
It marks the low-pressure regulator type, used where the regulated setpoint sits below the standard type's range. The exact range for the low-pressure type is not published in our data, so tell us the setpoint you need and we will verify it against the catalogue. The rest of the code decodes as: 300 size, G3/8 port, M manual drain, C round gauge with psi scale, G thread, bracket included.
