The AirTAC GFR400C10LJC1T 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 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 GFR400C10LJC1T is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is size 400 with a 3/8 in NPT port, filters to the standard 40 um grade, drains condensate by differential pressure, and carries a round pressure gauge with an MPa scale. It is the low-pressure (L) regulator type, is supplied without a mounting bracket, has no reverse/check valve fitted, and the bowl is metal.
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 options for drain type, 5 um filtration (code W), gauge style and scale, G or NPT thread, and bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow 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.

Feeds filtered, regulated air to pneumatic clamps and light press fixtures that run at low set pressures. The 40 um element protects downstream valve seals from particulate and water, and the round MPa gauge gives a direct readout while setting.
Conditions the air feeding cylinder-driven diverters and pushers on a packaging conveyor. The differential-pressure drain sheds condensate as the line breathes through shifts, and the regulator holds a steady low setting for consistent actuator stroke behavior.
Supplies water- and particle-filtered, regulated air to spray guns and coating applicators on a low-pressure finishing line, helping keep condensate and grit out of the air path so finish quality stays consistent.
Choose the size by the port and flow your line needs: this unit is size 400 with a 3/8 in NPT port, and the smaller 200/300 and larger 600 frames step port size up or down. Drain type matters: the differential-pressure drain fitted here passes condensate automatically as the pressure differential rises, while automatic (A) and manual (M) drains are orderable alternatives. The 40 um element is standard; specify W for 5 um filtration. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales - this unit carries the round gauge with MPa scale. Thread is NPT here; PT is the standard thread and G (BSPP) is also an order option. Brackets are optional, and this unit is supplied without one.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your application and we will confirm sizing, and the adjustment range of this low-pressure regulator variant, from the datasheet 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 number here. Send us your application details and we will confirm the flow curve and sizing against your requirement from the datasheet on request.
This unit is the low-pressure regulator variant, intended for circuits that operate at low set pressures. The exact adjustment range for this variant is not published in our data, so we confirm it from the AirTAC datasheet on request. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing.
