The AirTAC GFR400C10LF1TK AirTAC Filter Regulator NPT 3/8 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 AirTAC GFR400C10LF1TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit is ported NPT 3/8 in and built as the low-pressure regulator type, filtering to the standard 40 um grade. It carries a differential-pressure drain, an embedded square gauge scaled in MPa, a reverse (check) valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um filter element (code W), gauge scales in psi or bar, an external round gauge, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Supplies filtered, regulated air to the seal-and-cut cylinders on a carton sealing line, with the fitted check valve blocking reverse flow through the unit.
Regulates supply to a pneumatic clamping fixture on a machining cell where the workpiece calls for a lower regulated pressure than the main line runs.
Point-of-use filter regulation for a robotic pick-and-place cell, keeping water and particles down to 40 um out of the valve and cylinder circuit while the gauge shows line pressure.
Choose the size by the port and flow step: sizes 200, 300, 400 and 600 rise in port and flow capacity, with this unit at size 400 on NPT 3/8 in. Drain comes as differential-pressure (this unit), automatic (A) or manual (M); filter grade is 40 um standard or 5 um with code W; the embedded square gauge can be ordered in MPa, psi or bar scales, with an external round gauge optional. Threads are PT as standard with G (BSPP) and NPT as order options, and a bracket is included. This is the low-pressure (L) regulator type; its exact adjustment range is not published in our data, so we confirm it on request. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR flow as curves rather than a single rated figure, so we do not quote a rated l/min, m3/h or SCFM number. Send us your flow and pressure conditions and we will confirm the sizing from the datasheet on request.
This unit uses the differential-pressure drain, the default option in the GFR range. Automatic (code A) and manual (code M) drains are order options if your installation is better served by one of those choices.
