The AirTAC GFR400C10LJF2T AirTAC Filter Regulator NPT3/8 Low-Pressure 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 GFR400C10LJF2T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/8 in NPT port, a low-pressure regulator type, 40 um standard filtration and a differential-pressure drain, with a metal bowl, an embedded square gauge scaled in psi, no reverse/check valve and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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 port sizes from 1/8 to 1 in, and options including automatic or manual drains, a 5 um filter element (code W), G or NPT threads, gauge scales in MPa, psi or bar, and a reverse/check valve. Flow for this unit is published as curves rather than a single rated figure, so ask us to confirm the datasheet and the sizing 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.

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.

On a pneumatic clamping fixture that holds workpieces at reduced pressure, this unit filters the shop air supply and holds a steady low set pressure to the clamping valves.
At the drop feeding a cartoning or wrapping line, the unit cleans water and particles out of the compressed air and regulates the pressure supplying the machine's cylinders.
In an automated assembly cell running air cylinders and small air tools, the unit conditions the branch line and lets technicians set a stable low working pressure for delicate operations.
Size and port set the capacity: the GFR400 steps up from the 200 and 300 series with a 3/8 in port, so match the size to the air demand of the circuit rather than to the pipe alone. Where this unit differs from a standard GFR400 is the low-pressure regulator type, intended for circuits that hold lower set pressures; the exact adjustment range for the low-pressure variant is not published in our material, so confirm it with us before ordering. Other decodable choices across the family: drain type (differential-pressure as here, automatic, or manual), filter grade (40 um standard, 5 um with code W), gauge (square embedded or round external, scaled in MPa, psi or bar - this unit is a square psi gauge), thread (PT is the standard, G and NPT are order options - this unit is NPT), and bracket (not included with the J code). Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 flow for the GFR400 as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your air demand and line details and we will confirm the sizing from the datasheet on request.
This unit's blank drain code is the differential-pressure type: it bleeds collected condensate using the pressure difference across the filter element, with no manual attention in normal operation. If your application needs a different arrangement, the family is also available with an automatic drain (code A) or a manual drain (code M).
