The AirTAC GFR40015LC2W AirTAC Filter Regulator PT1/2 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR40015LC2W is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body with one drain bowl. This configuration is built for 1/2 in (PT1/2) piping, carries the 5 um (code W) element instead of the 40 um standard, and uses the differential-pressure drain, the default drain for this family. The regulator is the low-pressure (L) type, a round gauge with a psi scale is fitted, the polycarbonate bowl serves non-freezing compressed air from -5 to 70 C at up to 1.0 MPa (145 psi) inlet, and a mounting bracket is included.
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 offers a choice of drain type, 40 um or 5 um filtration, gauge style and scale, G and NPT thread options, and bracket variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

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.

Filtered, regulated air to pneumatic clamps on a CNC milling fixture where the clamping circuit runs at low setpoints and the 5 um element protects the clamp valves from water and fine particulate.
A filter regulator feeding gripper and pusher cylinders on a bottling conveyor, with the differential-pressure drain handling condensate through continuous production shifts and the local psi gauge giving operators a setpoint reference.
Point-of-use conditioning on a laboratory air drop where instruments need 5 um filtered air held at a stable low pressure, read directly on the fitted round psi gauge.
Size 400 with PT1/2 ports sits in the upper half of the GFR range; step between 200, 300, 400 and 600 according to the flow your line needs - we can check the curve against your demand before you order. The choices decodable from the code are: drain type (differential-pressure here; automatic or manual also available), filter grade (5 um here versus the 40 um standard), gauge (round, psi scale here; the embedded square gauge with MPa, psi or bar scales is the alternative), thread (PT is the standard; G and NPT are order options) and the included bracket. The L in the code marks the low-pressure regulator type; its exact regulation range is not published, so confirm it with us 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the sizing from the GFR400 datasheet on request.
GFR400 is the filter-regulator series in size 400, 15 decodes to the PT1/2 port, L marks the low-pressure regulator type (exact range not published - confirm with us), C2 is the round gauge with a psi scale, and W is the 5 um filter element instead of the 40 um standard. The drain is the differential-pressure type and a bracket is included.
