The AirTAC GFR400C15F2TK AirTAC Filter Regulator NPT1/2 with Gauge 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 GFR400C15F2TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/2 in NPT port, 40 um standard filtration, a differential-pressure drain, a fitted square gauge scaled in psi, a reverse/check valve, and a mounting bracket. It is a standard-type regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits compressed-air duty where the drain can be serviced as collected water builds.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT, G and NPT, 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge choices and scale options, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Point-of-use conditioning for a CNC machining centre: the 1/2 in NPT port feeds the machine's pneumatic circuits with filtered, regulated air, and the psi gauge lets setters verify setpoint at the machine.
Conditioning the air feeding cylinder-driven packaging machinery on a bottling or cartoning line, where the check valve holds the downstream setting if upstream supply dips during changeovers.
A wall-mounted air drop at an automotive paint and body shop: particulate and water are stripped before regulation, protecting spray guns and air tools fed from the 1/2 in line.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step up to size 600 or down to 300 depending on the flow your line needs - we will check the published flow curves against your application before you order. Filtration is 40 um as coded here; choose the W option for 5 um if downstream valves or instruments need finer protection. The drain is differential-pressure (the default); automatic (A) and manual (M) drains are available if your maintenance routine suits them better. The gauge is square and scaled in psi; round gauges and MPa or bar scales are alternatives. Thread is NPT as coded, with PT and G offered as order options, and the bracket is included.
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 this family as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing data from the datasheet on request.
The K in the code means a reverse/check valve is fitted, which holds the downstream pressure setting if the upstream supply is interrupted. Omitting the K gives the same unit without the valve; drain type, filter grade, gauge scale and thread (PT, G or NPT) are also orderable choices.
