The AirTAC GFR400C15C2TK 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 AirTAC GFR400C15C2TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 400 unit is threaded 1/2 in NPT, filters to 40 um, discharges condensate through a differential-pressure drain, and carries an external round gauge reading in psi. A reverse/check valve is fitted and the mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in and PT, G or NPT threads. For this configuration the regulation range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to 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. 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.

Placed at the machine's air inlet, the GFR400C15C2TK strips water and particulate from shop air and holds a steady setpoint for spindle clamps, tool changers and pneumatic actuators on a 1/2 in drop.
On a bottling or cartoning line, the unit conditions the air feeding conveyor diverters, case erectors and bag-closing cylinders, keeping regulator drift out of the sequence so changeover settings hold between shifts.
At the point of use on a factory air ring main, this filter regulator gives each assembly or test bench its own clean, regulated supply, with the psi gauge letting technicians read and verify working pressure at the bench.
Size and port drive capacity: the 400 size with a 1/2 in NPT port sits in the upper-middle of the GFR range (200/300/400/600), so step up or down a size to match the air demand of your line. Drain type is a real choice: differential-pressure (this model), automatic (code A) or manual (code M). Filter grade is 40 um standard or 5 um with code W; the gauge can be ordered with MPa, psi or bar scales; and thread is PT as standard with G and NPT as order options.
Because flow is published as curves rather than a single rated figure, 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 GFR400 capacity as flow curves rather than a single rated figure, so there is no one number we can quote honestly. Send us your working pressure, expected air consumption and duty cycle, and we will confirm the sizing from the datasheet before you order.
The blank drain code in GFR400C15C2TK specifies a differential-pressure drain, which discharges collected condensate automatically as the pressure drop across the filter builds - no timer or operator attention needed. If your maintenance routine prefers it, the same 400 size can be ordered with an automatic drain (code A) or a manual drain (code M).
