The AirTAC GFR40015LC2GK AirTAC Filter Regulator G1/2 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 PT1/2" 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 GFR40015LC2GK 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 G1/2 (BSPP) female port, the low-pressure regulator type, a 40 um standard filter element and the differential-pressure drain, the default drain option for this family. A round pressure gauge reading in psi is fitted, a reverse/check valve is built in, and a mounting bracket is included. The polycarbonate bowl lets you see the condensate level at a glance. Maximum working (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 ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), a 5 um optional filter element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G or NPT thread options to order. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Point-of-use filtered and regulated air for gripper and stopper cylinders on a bottling line, with the built-in check valve blocking reverse flow back toward the supply side.
A low-pressure regulator feeding clamping circuits that run below full line pressure, with the 40 um element keeping particulate out of the directional valves and fixture cylinders.
Filtered, regulated air for diverter and pusher cylinders on a packaging conveyor, with the differential-pressure drain and visible PC bowl making condensate easy to monitor.
Everything that matters in this family is decodable from the code. Step the size (200/300/400/600) and its matching port - here size 400 with a G1/2 port - against the flow your line needs. Choose the drain: differential-pressure (this unit, the default), automatic (A) or manual (M). Filter grade is 40 um standard; specify W for the 5 um element where finer particulate matters. Gauges: an embedded square gauge is standard and an external round gauge is optional, in MPa, psi or bar scales - this unit carries the round psi gauge. Thread: PT is the standard, while G (BSPP) and NPT are catalogue options to order - this unit is the G version. Brackets are included unless the J code is specified. One honest note: AirTAC publishes flow as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet curve for this 1/2-inch size before you order.
L marks the low-pressure regulator type. The exact regulation range for this variant is not published in the standard tables, so we confirm it from the datasheet on request. If you need the standard range instead, the standard type with this differential-pressure drain regulates 0.15-0.9 MPa (20-130 psi).
