The AirTAC GFR400C15LC1TK 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 GFR400C15LC1TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 400 unit is ordered with a 1/2 in NPT port, the low-pressure regulator type, a differential-pressure drain, the standard 40 um filter element and a metal bowl. It comes with a round MPa gauge fitted, a reverse (check) valve, and a mounting bracket. 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 GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for drain type, 5 um filtration (code W), gauge style and scale, G (BSPP) or NPT thread, and bracket choice. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet 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.

Clean, regulated air to clamps and fixtures on a machining cell, with the fitted check valve blocking reverse flow if the supply side drops.
Filtered air at a controlled low pressure to diaphragm valve actuators on a treatment skid, where the low-pressure regulator type suits circuits that run well below standard line pressure.
Water and particulate removed ahead of cylinder and gripper circuits on a packaging line, with the 1/2 in port feeding a main drop on the machine.
Size and port set the air capacity: the GFR400 is the larger 1/2 in port step of the GFR range, so match the size to the air demand of your circuit - we can check the published flow curves against your requirement. Drain is differential-pressure on this code (the default), with automatic (A) and manual (M) available; on standard-type units the drain type also affects the adjustment range. Filter grade is 40 um standard; choose code W for 5 um where finer particulate removal matters. This variant is the low-pressure regulator type, whose adjustment range is not published in the catalogue - we confirm it on request; standard-type GFR units with differential-pressure or automatic drain adjust 0.15-0.9 MPa (20-130 psi). The gauge here is the external round type with MPa scale; the embedded square gauge and psi or bar scales are the other options. Thread is NPT on this code; PT is the standard and G (BSPP) is also a catalogue option. Bracket included; code J orders without.
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, not as a single rated figure, so we do not quote a number here. Send us your supply pressure, target downstream pressure and air demand, and we will confirm the flow from the datasheet before you order.
This GFR400 variant is the low-pressure regulator type, intended for circuits that operate well below standard line pressure. Its exact adjustment range is not published in the catalogue; for reference, standard-type GFR units with differential-pressure or automatic drain adjust 0.15-0.9 MPa (20-130 psi). We confirm the low-pressure range on request.
