The AirTAC GFR400C15LC1T 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 AirTAC GFR400C15LC1T is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 400 unit is built for 1/2 in NPT ports and carries the low-pressure regulator type, a 40 um standard filter element, a differential-pressure drain, a round MPa pressure gauge and a mounting bracket. The polycarbonate bowl lets you see condensate building up at a glance, and the maximum inlet pressure is 1.0 MPa (145 psi).
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 including automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Working temperature is -5 to 70 C, non-freezing. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm flow 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.

Feeding spray guns on a paint finishing line that run below standard shop pressure: the low-pressure regulator type holds the gentler setting the guns were set up for, while the 40 um element keeps water and pipe scale out of the finish.
Air preparation for pneumatic clamps on a machining fixture: filtered, regulated air at the pressure the clamp circuit was designed around, with the fitted MPa gauge giving the operator a live reading at the machine.
Supplying sorting and packaging conveyor cylinders with clean, regulated air; the differential-pressure drain clears accumulated condensate as air passes through, so the bowl does not need daily manual dumping.
Size 400 with 1/2 in NPT ports sits in the upper half of the GFR range; the family steps through 200/300/400/600 with ports from 1/8 to 1 in, so size up or down to match the air your line actually uses. AirTAC publishes flow as curves, not a single rating, so send us your demand and we will confirm the right size from the datasheet before you order. This code pairs the low-pressure regulator type (we confirm its exact regulation range on request) with a 40 um element; a 5 um element (W) is available for finer filtration. The drain here is differential-pressure, with automatic (A) and manual (M) variants in the family. The round gauge with an MPa scale is fitted; square gauges and psi or bar scales are order options. Thread is NPT on this code, with G and PT available to order, and the mounting bracket is included.
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 series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line's air demand and we will confirm the flow from the datasheet and check the sizing against your application before you order.
The C1 in GFR400C15LC1T specifies the round gauge with an MPa scale; the embedded square gauge is the standard fitting, and psi or bar scales can be ordered instead. The L marks the low-pressure regulator type rather than the standard one - its exact regulation range is not published as a single figure, so we confirm it from the datasheet on request.
