The AirTAC GFR30010MC1WTK AirTAC Filter Regulator NPT 3/8 in 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 GFR30010MC1WTK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the 300 size with a 3/8 in NPT port, fitted with the fine 5 um filter element (code W), a manual drain for the PC (polycarbonate) bowl, and a round external pressure gauge scaled in MPa. A reverse/check valve (code K) is fitted, and the unit includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 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 sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um fine filtration, embedded square or external 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 we confirm the 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. 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) | 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. |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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, pressure-controlled air to the tool-clamp and pallet-change circuits of a CNC machining centre, with the 5 um element guarding fine pilot valves and the round gauge letting setters verify set pressure at a glance.
Placed ahead of the pick-and-place and sealing cylinders on a packaging conveyor line, it removes condensed water and fines and holds a steady regulated pressure so carton-forming motions stay repeatable through the shift.
Mounted on the bracket at the drop of a robotic assembly cell, it conditions the air feeding grippers and screwdriver feeders, with the check valve holding the downstream setting if supply pressure dips.
Size and port set the capacity: this unit is size 300 with a 3/8 in NPT port, one step up from the 1/4 in 200 size, and the 400/600 sizes step further for larger air demand. The 5 um element (code W) suits points of use that need finer particulate control than the 40 um standard element. The manual drain means an operator opens the bowl drain periodically instead of relying on an automatic or differential-pressure drain. The round gauge is scaled in MPa; psi and bar scales are also available. Thread is NPT here, with PT (standard) and G as order options, and the bracket is included.
Flow for this family is published as curves, not as a single rated figure, so please ask us to confirm sizing against your air demand before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 series as curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your air demand and line pressure and we will confirm the sizing from the datasheet curve on request before you order.
The M in the code selects a manual drain on the PC bowl: an operator opens the drain periodically to expel collected water instead of relying on the automatic or differential-pressure drain options. If unattended drainage matters at your site, the same 300 size is available with those drain types, and we can confirm the alternative model code on request.
