The AirTAC GFR400C15LC2 AirTAC Filter Regulator PT1/2 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 GFR400C15LC2 is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. Compressed air passes through a 40 um element that strips out water and particulate, then through a low-pressure-type regulator, with the downstream pressure shown on the round psi gauge fitted to this configuration. The 1/2 in PT port suits main air drops and larger machine supplies, the differential-pressure drain bleeds collected condensate automatically as flow passes through, and the polycarbonate bowl lets you see the liquid level at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and bracket or no bracket. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow figures for your application on request.

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 a packaging machine's valve island and cylinders from a 1/2 in main drop: the 40 um element keeps line debris and condensed water out of the valves while the low-pressure-type regulator holds a gentle, stable supply pressure for delicate sealing and forming actuation.
Supplying clamping cylinders on a machining-centre fixture, where the regulator sets a repeatable low clamp pressure and the round psi gauge gives the operator a visible reference, while filtered air protects the clamping valves from water and swarf-carrying compressed air.
Air prep for the divertors, stoppers and pop-up rollers on a sortation conveyor: the filter-regulator cleans and tames the supply at the point of use, the differential-pressure drain handles condensate without operator attention, and the 1/2 in port carries the volume those actuators draw.
Start with the size and port: 400 is the larger step in the GFR range, and this unit's PT1/2 (1/2 in) port matches heavier machine supplies - step up or down only if your line flow demands it. Next, pick the drain: this unit uses the differential-pressure drain (the default), which discharges condensate automatically as air flows through; a manual-drain or automatic-drain version can be ordered if your duty cycle suits those better. Filtration here is the standard 40 um grade - choose the 5 um (W) option only where downstream equipment needs finer particles removed. The gauge on this unit is the external round type with a psi scale; an embedded square gauge and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the mounting bracket is included. Finally, the honest routing: AirTAC publishes flow as curves, not a single rating, so ask us to confirm sizing against your application 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 flow for the GFR400 series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and required flow, and we will confirm the figures from the datasheet on request before you order.
The L in the code marks this as the low-pressure-type regulator variant rather than the standard type, and C2 specifies the external round gauge fitted with a psi scale (MPa and bar scales are the other catalogue options). The exact adjustment range for the low-pressure type is not published in the materials at hand, so we confirm it on request. The unit also carries the standard 40 um filter element and the differential-pressure drain.
