The AirTAC GFR40010JC3TK 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 PT3/8" 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 GFR40010JC3TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain, a round pressure gauge reading in bar, a built-in reverse/check valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard, G and NPT to order), drain types, 40 um or 5 um filtration, gauge styles and scales, and check-valve or bracket options. 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 0.15 - 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.

| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Clean, regulated air to a bench or floor pneumatic press: the 40 um element keeps water and swarf out of the valve stack while the regulator holds a steady working pressure at the cylinder.
Point-of-use prep for wrapper and cartoner actuator circuits, where the check valve holds downstream pressure during upstream dips and the bar gauge gives operators a clear setpoint reading.
Filtered, regulated air for conveyor diverters, stoppers and gate cylinders along a transfer line, with the differential-pressure drain handling condensate automatically in service.
Start with the port step: this unit is size 400 with a 3/8 in NPT port; step up or down through the 200/300/400/600 range to match the line size and the flow your circuit needs. The 40 um element is the standard grade for general plant air; specify the 5 um (W) variant if the application calls for finer filtration. The differential-pressure drain is the default and suits most installations; automatic or manual drain variants exist if your duty demands them. The round gauge in this configuration reads in bar; square embedded gauges and MPa or psi scales are also available. PT is the standard thread, with G and NPT as order options - this unit is the NPT version.
Flow for this series is published as curves, not as a single rated figure, 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 the GFR400 series as curves rather than a single rated figure, so no single number is quoted. Send us your line size and air demand and we will confirm the appropriate sizing from the datasheet on request.
In this code, C3 means a round pressure gauge with a bar scale is fitted, T means the 3/8 in port is NPT thread, and K means a reverse/check valve is built in. The J earlier in the code means no mounting bracket is supplied, and the standard 40 um filter element with differential-pressure drain applies.
