The AirTAC GFR40010AJC3T 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 automatic 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 GFR40010AJC3T is an AirTAC GFR400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built around a 3/8 in NPT port, a 40 um filter element, and an automatic drain that expels collected condensate without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round gauge on a bar scale is fitted so the set pressure can be read at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 400 size, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, manual or automatic drains, a 5 um element option, gauge choices, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Feeding clean, regulated air to a CNC machine's pneumatic clamps, tool-change cylinders and chip-ejection jets, with the automatic drain handling condensate from a compressor line that runs through shifts without an operator nearby.
Conditioning the air that drives carton-erecting and case-sealing cylinders on a packaging line, where the 40 um element keeps wear particles and water out of the valve stack and the bar gauge lets the line technician verify set pressure.
Serving as the point-of-use filter regulator on a branch line feeding pneumatic actuators and air cylinders across a factory floor, holding a steady downstream pressure regardless of upstream swings in the header.
Size and port drive the choice: step up from 400 only if the application's air demand outgrows a 3/8 in line, since larger sizes carry larger ports and more flow capacity. Drain type is a real decision here: this code carries the automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drains remain available in the series. The 40 um element is the standard grade, with a 5 um (W) option where finer filtration is needed. The fitted round gauge reads in bar; square embedded gauges and MPa or psi scales are the other catalogue choices. Thread is NPT on this code, with PT as the standard and G as an order option, and brackets can be added where this bracketless code is not panel- or wall-mounted.
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 there is no one rated flow number we can quote. Tell us your application's air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code selects the automatic drain, which expels collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot or the line runs unattended. The series also offers a manual drain and a differential-pressure drain (the default), so you can match the drain to how the installation is serviced.
