The AirTAC GFR400C10LJF2 AirTAC Filter Regulator PT3/8 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 GFR400C10LJF2 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 the size 400 unit with a PT3/8 port, the low-pressure regulator type, a 40 um standard filter element, a differential-pressure drain and the embedded square gauge scaled in psi. No mounting bracket is included with this code, the bowl on this size is polycarbonate (PC), and the operating temperature 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 in to 1 in, and options include 5 um (W) filtration, automatic or manual drains, alternative gauge scales (MPa/psi/bar) and G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Feeds clean, low-pressure regulated air to the clamping cylinders on a machining fixture, holding workpieces at a gentle set pressure while the 40 um element keeps scale and condensate out of the clamp circuit.
Supplies filtered and regulated air to the pusher and flap-fold cylinders on a carton-sealing conveyor, where the low-pressure type keeps actuator pressures moderate and the differential-pressure drain clears collected water without stopping the line.
Conditions the air feeding gripper and capping-head actuators on a bottling line, combining water and particulate removal with low-pressure regulation in one body so a single PT3/8 drop serves the whole station.
Choose the size and port against the air demand of your line: this unit is size 400 with a PT3/8 port, and larger sizes carry larger ports and more flow. The low-pressure type (L) suits circuits regulated below the standard range - confirm the exact adjustment range with us, as it is not published as a single figure. Filtration here is the 40 um standard element; specify 5 um (code W) where finer protection is needed. The drain is differential-pressure, with automatic (A) and manual (M) versions available. The square gauge on this code is scaled in psi; MPa and bar scales and an external round gauge are options. Thread is PT as standard, with G (BSPP) and NPT available to order, and this code omits the mounting bracket. 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures against your requirement before you order.
The L code marks the low-pressure regulator variant of the GFR400. The exact adjustment range for this variant is not published as a single figure, so we confirm it on request. Maximum inlet pressure is 1.0 MPa (145 psi), the same as for all G-series units, and operating temperature is -5 to 70 C (non-freezing).
