The AirTAC GFR400C15C2T AirTAC Filter Regulator 1/2 in NPT 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 GFR400C15C2T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure in one body. This configuration is built for 1/2 in NPT ports, filters to 40 um as standard, and sheds condensate through a differential-pressure drain. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, a round pressure gauge reading in psi is fitted, and a mounting bracket is included. 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 from the GFR400 size class, one of four sizes (200, 300, 400, 600) that step up in port and flow. Options across the series include 5 um filtration (code W), automatic or manual drains, G or NPT threads, and alternative gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm the 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 clamps and fixtures on a machining cell: the 40 um element keeps water and swarf out of the clamp circuit while the regulator holds a consistent clamping pressure across every cycle.
Supplying pick-and-place and sealing cylinders on a packaging conveyor, where the differential-pressure drain sheds condensate as air flows, so the line keeps running without drain stops.
Supplying quarter-turn actuated valves on a process skid, with the round psi gauge letting operators verify the set pressure at a glance during rounds.
The real choices in this series are the size and port step, the drain type, the filter grade and the gauge. Size 400 with a 1/2 in port sits in the upper half of the range; step to 600 for larger ports or down to 300/200 for smaller lines. Drains come as differential-pressure (this unit), automatic (code A) or manual (code M); filtration is 40 um standard or 5 um with W. Gauges are an embedded square gauge as standard or an external round gauge, scaled in MPa, psi or bar - this unit reads psi. Threads are PT as standard with G and NPT as order options, and a bracket is included unless code J is specified.
Flow for the GFR series is published as curves, not a single rated figure, so we cannot quote one number here. Send us your application details 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. 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 we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for this 1/2 in NPT unit before you order.
The C2 code specifies the optional external round gauge with a psi scale. The embedded square gauge is the standard fitting, and MPa, psi and bar scales are all available - pick the scale that matches the instruments already on your plant.
