The AirTAC GFR400-15C2TK AirTAC Filter Regulator NPT1/2 Round Gauge psi 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 AirTAC GFR400-15C2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit has a 1/2 in NPT port, a 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round pressure gauge reading in psi. A reverse (check) valve is fitted, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) at inlet pressures up to 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, optional 5 um filtration (code W), automatic or manual drains, square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Feeds clean, regulated air to the cylinders and actuators on a cartoning or wrapping line, with the check valve holding the set pressure if upstream supply dips.
Supplies filtered air at a stable, repeatable pressure to a bench-mounted pneumatic press or clamping fixture, with the psi gauge giving the operator a clear setpoint readout.
Conditions the air driving diverters, stoppers and gate cylinders on a conveyor line, protecting valves from water and debris while keeping actuation pressure consistent.
Size 400 with a 1/2 in port suits lines with substantial air demand; step down to 200/300 or up to 600 depending on the flow your circuit needs - we can check the published flow curves against your consumption before you order. This unit ships as standard with a 40 um element (choose code W for 5 um where finer filtration is needed), a differential-pressure drain (automatic or manual drains are order options), and a round psi gauge; square gauges and MPa or bar scales are also available. Thread is NPT here; PT is the standard and G (BSPP) can be ordered. A mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and air consumption and we will confirm the flow and sizing from the datasheet on request.
C2 means a round external pressure gauge with a psi scale is fitted (an embedded square gauge in MPa, psi or bar scales is also available in the family), and K means a reverse (check) valve is fitted. The drain on this unit is the differential-pressure type; automatic (A) and manual (M) drains are order options.
