The AirTAC GFR400C10JF2K AirTAC Filter Regulator PT3/8, 40 um 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 GFR400C10JF2K is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit has a PT3/8 (3/8 in) port, a 40 um filter element, a differential-pressure drain, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, an embedded square gauge scaled in psi, and a reverse (check) valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with this code; a bracket is available as an option.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in. to 1 in., drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scale choices and G (BSPP) or NPT thread options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm flow and full datasheet details 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 0.15 - 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.

Conditioning the air supply to a bench pneumatic press: the 40 um element strips water and swarf from the shop air line while the regulator holds a steady setting at the press valve, and the fitted reverse valve holds the downstream circuit against backflow if the supply dips.
A filter regulator at the air drop feeding a carton-forming and sealing machine, giving the cylinder stations clean air at a set pressure with a local psi gauge for operator checks at each shift.
Supplying filtered, regulated air to a laboratory automation skid driving sample-handling cylinders and air jets, where the 3/8 in PT connection and a fixed regulator setting keep actuation repeatable run to run.
Size and port: GFR400 is the size 400 frame with a PT3/8 (3/8 in) port; step through sizes 200/300/400/600 as your flow requirement changes - larger sizes carry larger ports and more flow. Drain: this unit uses the differential-pressure drain (the blank-code default); automatic (A) and manual (M) drains are order options. Filtration: 40 um element as supplied; specify the W code for the 5 um grade. Gauge: the embedded square gauge on this model is scaled in psi; MPa and bar scales, and an external round gauge, are options. Thread: PT is the standard; G (BSPP) and NPT are order options. Bracket: the J code means no bracket is included - order one if you need to mount the unit off the line. Flow for this series 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. 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 number here. Send us your application details and we will confirm the flow and the full datasheet for this model on request.
Yes. The 40 um element is the catalogue standard grade, and the W code gives a 5 um element in the same family. If your downstream equipment needs finer filtration, order the W variant of this size and port instead.
