The AirTAC GFR400C10MLJF2T AirTAC Filter Regulator NPT3/8 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR400C10MLJF2T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 400 unit is threaded NPT3/8 (3/8 in), carries the 40 um standard filtration grade, and has a metal bowl with a manual drain, so condensate is released by hand as part of a maintenance routine. The regulator is the low-pressure type, and the unit includes an embedded square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. No reverse/check valve is fitted and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR400 series. Across the GFR line you can order different sizes and ports, differential-pressure, automatic or manual drains, a 5 um element (code W), gauge scales in MPa, psi or bar, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.15 - 0.9 MPa (20 - 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.

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.

Point-of-use filtration and low-pressure regulation for gripper and clamp cylinders on a bottling line, with a psi-scaled gauge that US maintenance staff can read at a glance and a manual drain suited to a supervised checks routine.
Feeding air knives that blow dust and moisture off products travelling on a conveyor, where the 40 um element helps protect the nozzles and the low-pressure regulator holds a gentle, stable blow-off setting.
Conditioning the air supply to a laboratory bench or test rig that runs at reduced pressure, keeping water and particles out of sensitive instruments while the square psi gauge gives a clear local reading.
Size and port step up with demand: GFR bodies come in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", so choose the size whose flow curve covers your air consumption - we can check the curve against your application. Choose the drain: manual (this unit, emptied by hand), automatic, or the differential-pressure default. Filtration is 40 um standard or 5 um with code W. The embedded square gauge is standard; an external round gauge and MPa or bar scales are options - this code carries the square gauge with a psi scale. Thread is NPT on this model; PT is the AirTAC standard and G (BSPP) is also an order option. Brackets are optional, and this configuration is supplied without one. Because the regulator is the low-pressure type, its exact adjustment range is not published in our data - confirm it with us before ordering if your set pressure is critical.
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 GFR400 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 curve and sizing from the datasheet on request.
The L code marks the low-pressure regulator variant rather than the standard one; its exact adjustment range is not published in the data we hold, so ask us to confirm it from the AirTAC datasheet if you have a specific set pressure. The M code means the bowl drain is manual: condensate is released by hand instead of automatically, which suits installations that are checked regularly.
