The AirTAC GFR40010MC2GK AirTAC Filter Regulator G3/8 Manual Drain 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 GFR40010MC2GK is a GFR400 series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration has a G3/8 port (G thread; PT is the standard thread, with G and NPT available as order options), a manual drain on the PC (polycarbonate) bowl, a 40 um filter element, and a round gauge reading in psi. A reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR range covers sizes 200, 300, 400 and 600, with a choice of ports, manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) elements, 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 ask us to 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.

| 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. |

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 a clean, pressure-controlled air supply to the clamping and forming cylinders of a bench or C-frame press, where the 3/8 in port suits a mid-size cell supply and the manual drain suits a unit drained at shift start.
Supplying diverters, stoppers and gripper cylinders along a packaging or bottling conveyor line, with the 40 um element protecting valves from water and particulate carried in the shop air.
Regulating air to the tooling clamps and weld-gun actuation circuits of a robotic welding cell, where the fitted reverse/check valve helps hold the downstream circuit and the psi gauge gives operators a familiar readout.
Size up by port and required flow: the 200, 300, 400 and 600 bodies step up in port and capacity, and this unit sits at 3/8 in on the 400 body. Choose the drain to match service: manual (as fitted here, which gives a 0.05-0.9 MPa / 7-130 psi regulation range), automatic, or differential-pressure. Element grade is 40 um standard, with 5 um (code W) where finer filtration is needed. Gauges are offered as the embedded square type or an external round gauge with MPa, psi or bar scales; this unit carries a round psi gauge. Thread is G here, PT is the standard and NPT can be ordered, and a mounting 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this range as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for GFR40010MC2GK on request before you order.
A manual drain means the bowl is emptied by hand, which suits units that are easy to reach and drained as part of a routine. On this manual-drain version the regulation range is 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions of the same family regulate 0.15-0.9 MPa (20-130 psi). Choose automatic if the unit sits where it cannot easily be drained by hand.
