The AirTAC GFR30010MC2WT AirTAC Filter Regulator 3/8 in NPT 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 AirTAC GFR30010MC2WT is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is threaded 3/8 in NPT, carries a 5 um filter element, and uses a manual drain so the bowl is emptied by hand on your schedule. The fitted round gauge reads in psi, and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl gives a clear view of condensate and element condition.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

|---|---|
| 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)). |
| (blank) | Standard 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. |
| 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.

Feeds clean, regulated air to the tool-change and clamping circuits of a CNC machining centre, with the 5 um element guarding fine pneumatic valves and the psi gauge set to the machine's supply pressure.
Mounted at the drop of a packaging line's air header to filter and regulate the supply to bagger and carton-sealer cylinders, with manual drain emptied during scheduled line cleaning.
Conditions the air feeding analytical instruments and pneumatic sample-handling rigs in a lab, where the 5 um grade and a hand-set psi regulator protect sensitive pilot-operated components.
Size and port set the capacity: the 300 size with a 3/8 in NPT port suits lines above the 200/1/4 in step, but because AirTAC publishes flow as curves rather than one rated number, send us your demand and we will confirm sizing against the datasheet. Drain choice is real: manual (this unit, code M) is emptied by hand, automatic drains continuously, and the differential-pressure default drains on a pressure drop - pick manual where you want positive control and no bleed. Filter grade is a decodable choice: 40 um is standard, 5 um (code W, fitted here) for finer protection. Gauge scale (MPa, psi or bar) and PT vs G/NPT thread are ordered to match your panel; a bracket is included with this unit.
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. Send us your line pressure and air demand and we will confirm the flow and full datasheet figures for this 300-size, 3/8 in NPT unit on request before you order.
The M in the code selects a manual drain: you empty the polycarbonate bowl by hand when it suits your maintenance routine. Automatic drain is the choice where the unit is hard to reach or the line runs unattended, and the differential-pressure default drains on a pressure drop. All three drain types are orderable across the GFR range.
