The AirTAC GFR400C10JC2TK AirTAC Filter Regulator NPT3/8, 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 GFR400C10JC2TK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This configuration is built with a 3/8 in NPT port, standard 40 um filtration, a differential-pressure drain, a round gauge reading in psi, and a reverse (check) valve; it is supplied without a mounting bracket. The bowl on this 400 size is polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge styles and scales (MPa, psi or bar), and thread options (PT as the standard, with G and NPT orderable). Flow for this family is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

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 feeding the pusher and clamp cylinders on a bottling or packaging line, with the check valve helping hold the downstream setting if supply pressure dips.
A single point of air preparation for diverter gates, stoppers and lifters along a conveyor run, keeping moisture and pipe scale out of the valves they actuate.
Filtered, pressure-controlled supply to the clamping and tool-change circuits of a CNC machine or workholding fixture, where a steady set point protects repeatable actuation.
Step through size and port against your air demand: GFR sizes 200, 300, 400 and 600 cover ports from 1/8 to 1 in, and this 400 unit sits at the 3/8 in step. The drain on this code is differential-pressure (default); automatic (A) and manual (M) drains are orderable. Filtration is the standard 40 um element; specify W for 5 um when finer particulate capture matters. The round gauge on this unit reads in psi, with MPa and bar scales and an embedded square gauge as alternatives. Thread is NPT on this code; PT is the standard and G (BSPP) is orderable, and the J suffix means no mounting bracket. Because flow is published as curves, 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. 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 family as curves, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
K means a reverse (check) valve is fitted on this unit; it is a catalogue option, and codes without K have none. This code also decodes as: 400 size, 3/8 in NPT port, J = no bracket, C2 = round gauge with psi scale, T = NPT thread, and no drain or filter-grade letter, which means the differential-pressure drain and standard 40 um element.
