The AirTAC GFR400C15MLC1TK AirTAC Filter Regulator NPT 1/2 in 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 GFR400C15MLC1TK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/2 in NPT port, a manual drain, the standard 40 um filter element, a low-pressure regulator type, an external round pressure gauge with an MPa scale, and a built-in reverse (check) valve; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl for this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across drain type (differential-pressure, automatic or manual), 5 um filtration (code W), gauge style and scale (MPa, psi or bar), thread (PT standard; G and NPT as catalogue options) and bracket. Flow is published as curves rather than a single rated figure, 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.

Point-of-use filtration and pressure regulation feeding directional valves and clamping cylinders on a pneumatic press, with the check valve helping hold the circuit's set-up between cycles.
Filtered, regulated air for cylinder-actuated diverters, stops and pushers along a packaging conveyor line, with the manual drain serviced during scheduled line checks.
A filtered and regulated supply at the air drop of an assembly cell, feeding grippers, air tools and small actuators from the plant ring main.
Pick the size by port and required flow: this unit is size 400 with a 1/2 in NPT port, and the neighbouring sizes step port and flow capacity up or down. Drain type is a real choice: this unit has a manual drain you operate at intervals, while automatic and differential-pressure drain variants suit installations you cannot open regularly. The 40 um element is standard; specify code W for 5 um where downstream equipment needs finer filtration. The gauge on this unit is the external round type with an MPa scale; embedded square gauges and psi or bar scales are catalogue options. Thread is NPT here; PT is the standard and G (BSPP) is also available. This is the low-pressure regulator type - its exact adjustment range is not published in our data, so confirm it with us before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 flow as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the figures from the datasheet on request.
This configuration uses a manual drain: the bowl is drained by hand at intervals you set, rather than automatically. If you would rather not drain it manually, automatic (code A) and differential-pressure (default) drain variants are available in the same family.
