The AirTAC AirTAC GFR40010JC2TK Filter Regulator 3/8 in NPT 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 GFR40010JC2TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 400 configuration is supplied with a 3/8 in NPT port, a standard 40 um filter element, a differential-pressure drain, a round pressure gauge reading in psi, and a built-in reverse-flow (check) valve. The polycarbonate bowl lets you see the condensate level at a glance, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and options including a 5 um element (code W), automatic or manual drains, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing). Flow for the series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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. |
| 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. |
| 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.

Feed clean, regulated air to a machine tool's pneumatic valves and clamping actuators, keeping shop-air moisture and swarf out of the supply while holding a steady setpoint for consistent clamping force.
Condition the air feeding carton sealer and wrapper cylinders so jaws, pushers and clamps cycle predictably through a full shift, with the check valve preventing backflow through the unit when upstream supply dips.
Supply filtered, regulated air to pneumatic positioners and control valve actuators on a process skid, protecting the actuator supply from condensate and debris in the plant air ring main.
Pick the size by port and expected air demand: size 400 with its 3/8 in NPT port sits in the middle of the GFR range (200, 300, 400, 600; ports 1/8 to 1 in), so step up or down a size if your line draws more or less air. This unit carries the standard 40 um element; the W variant with a 5 um element is the orderable alternative for finer filtration. The drain here is differential-pressure, with automatic (A) and manual (M) versions available to order. Regulation range for this configuration is 0.15-0.9 MPa (20-130 psi). The fitted round gauge reads in psi; an embedded square gauge and MPa or bar scales are catalogue options. Thread is NPT as ordered, while PT is the AirTAC standard and G (BSPP) is also available. No mounting bracket is included with the J code. Because flow is published as curves and not a single rating, 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 G-series flow as curves rather than a single rated figure, so there is no one rated flow number we can quote. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
K indicates that a reverse-flow (check) valve is fitted, so downstream air cannot flow back through the unit. Units ordered without the K code do not include this valve.
