The AirTAC GFR30010MLC2WG AirTAC Filter Regulator G3/8, 5 um 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 GFR30010MLC2WG is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is the 300 size with a G3/8 (BSPP) port, a 5 um filter element (the finer W grade, against the 40 um standard), a manual drain on the bowl, the low-pressure regulator type, and an external round gauge reading in psi. The bowl on this 300 size is polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600, with port options in PT (standard), G and NPT, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge and scale choices, and a low-pressure regulator type. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. |
| W | Filtering grade 5 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.

Supplying filtered, low-pressure regulated air to clamping fixtures and swing cylinders on a CNC machining cell, where the 5 um element protects directional valves from particulate and the psi round gauge lets the setter read set pressure directly.
Feeding clean, regulated air to the pick-and-place cylinders and diverters on a carton packaging line, with the manual drain emptied during shift checks and the low-pressure type matching actuators that run below full line pressure.
Conditioning shop air for a laboratory test bench or pilot rig that needs fine 5 um filtration and gentle, stable regulation at reduced pressure, with the round psi gauge giving a clear local reading at the bench.
Step through the decodable choices: pick the size (200/300/400/600) so the port and flow capacity match your line, then the thread - PT is the standard, with G and NPT as order options. For the drain, manual suits supervised installations or infrequent condensate loads, while automatic or differential-pressure drains suit unattended duty. Choose 40 um for general protection or 5 um (this model's W grade) where downstream valves and cylinders need finer air. Gauge style and scale (square embedded, or external round in MPa/psi/bar) and the bracket option complete the selection. One honest note: AirTAC publishes flow as curves, not a single rated figure, so send us your flow and pressure requirements 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 a l/min or SCFM number. Tell us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The M in the code selects a manual drain: condensate is released by hand, which suits supervised installations or lines with light water loading - automatic or differential-pressure drains are the decodable alternatives on this family. The W selects the 5 um element instead of the 40 um standard, giving finer protection for downstream valves, cylinders and instruments.
