The AirTAC GFR Filter Regulator GFR400C10JF1K 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.
GFR400C10JF1K is a genuine AirTAC GFR-series filter regulator: filtration and pressure regulation in one body, with a drain bowl but no lubricator. This size 400 configuration has a PT 3/8 in. port, the default differential-pressure drain, the standard 40 um filter element, and the embedded square pressure gauge scaled in MPa. The J code means no mounting bracket is included, and the K code means a reverse (check) valve is fitted. Maximum working pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this drain type, and the working temperature range is -5 to 70 C, non-freezing. The bowl on a size 400 unit is polycarbonate (PC).
This is a factory-genuine AirTAC part. The GFR family runs in sizes 200, 300, 400 and 600 with ports from 1/8 in. to 1 in., with options including automatic or manual drain, a 5 um element (W), G (BSPP) or NPT thread variants, an external round gauge, a mounting bracket and the reverse check valve. AirTAC publishes flow as performance curves rather than a single rated figure, so ask us and we will confirm the datasheet and flow data for this exact model 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.

Place at the head of an assembly cell's air drop so the 40 um element strips water and particulate before the clamp and press cylinders, while the regulator holds a fixed setting on the embedded MPa gauge.
Use as the conditioning point feeding a bank of pneumatic directional valves on a machine manifold, with the check-valve code fitted where the circuit needs this option specified in the valve stack design.
Fit on a mobile service truck's compressor outlet to clean and regulate the air feeding impact wrenches and inflation tools, with the PT 3/8 in. port matching standard hose-whip assemblies.
Choose the size (200/300/400/600) and port (1/8 in. to 1 in.) against the air demand of the circuit; the 400 frame with PT 3/8 in. port covers mid-size supply lines between the 300 and 600 steps. This model uses the default differential-pressure drain; the A code gives a fully automatic drain and the M code a manual drain valve. The standard element is 40 um, with the W code available for the 5 um grade. The embedded square gauge reads in MPa, and psi (2) or bar (3) scales plus an external round gauge are alternatives. Thread is PT as standard with G (BSPP) and NPT as order codes, the J code omits the bracket, and the K code here adds the reverse check valve. Flow is published as curves rather than a single rating, so send us your application flow and we will confirm sizing before you order.
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 filter-regulator flow as performance curves rather than a single rated figure, so we do not quote one number. Share your required flow and operating pressure and we will confirm the datasheet and check the sizing of this PT 3/8 in. unit against your application on request.
PT is the standard thread on this series; G (BSPP) and NPT are catalogue options you select when ordering. Match the thread to the piping standard used in your plant or machine so the 3/8 in. connection seals correctly, and confirm the choice with us before ordering if you are unsure.
