The AirTAC GFR400C15LC2T AirTAC Filter Regulator NPT1/2 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 GFR400C15LC2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 400 unit is built with a 1/2 in NPT port, a 40 um standard filter element, a differential-pressure drain and the low-pressure regulator type. A round gauge with a psi scale is fitted and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on the size 400 frame is polycarbonate.
This is a genuine AirTAC part. The GFR400 series is one of four GFR sizes (200, 300, 400, 600) with ports stepping from 1/8 in to 1 in, and options across the family include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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 for the directional valves and cylinders that divert parcels on a distribution-centre sorting conveyor: the 40 um element keeps debris out of valve spools while the regulator holds the circuit pressure the actuators were set up for.
Feeding clamp cylinders on an assembly fixture where a lower, stable regulated pressure is wanted: the low-pressure type regulator suits circuits set away from standard ranges, and the fitted psi gauge gives operators a direct local reading.
Supplying pneumatic grippers and lifters on a laboratory sample-handling robot, where the 1/2 in NPT port feeds a distribution manifold and the filter removes water and particles before they reach sensitive gripper seals.
Choose the size and port against the flow your line needs: size 400 with a 1/2 in port sits in the upper-middle of the GFR range, which steps 200/300/400/600 across ports from 1/8 in to 1 in. Drain comes as differential-pressure (this unit), automatic (A) or manual (M); the filter element is 40 um standard with 5 um (W) available where finer filtration is needed. The fitted gauge reads in psi; the embedded square gauge and MPa or bar scales are the alternatives. Thread here is NPT, PT is the catalogue standard and G (BSPP) is an order option, and the bracket is included. Because flow is published as curves rather than one rated figure, send us your application conditions and we will confirm sizing 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 GFR400 flow as curves rather than a single rated figure, so we do not quote one number. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet before you order.
The L in the code marks the low-pressure regulator variant; the exact adjustment range for this type is not published in our data sheet, so confirm it with us before ordering if your circuit needs a specific setting window. The drain is the differential-pressure type, the family default, and automatic (A) or manual (M) drains are order options if you prefer a different regime.
