The AirTAC GFR400C15LF1T AirTAC Filter Regulator NPT1/2 Low-Pressure 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 GFR400C15LF1T is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, so one unit conditions the compressed air and holds downstream pressure at the set point. This configuration is built with 1/2 in NPT ports, a 40 um standard filter element, a differential-pressure drain, the low-pressure regulator type, an embedded square gauge scaled in MPa, a mounting bracket, and no reverse/check valve. 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. The GFR400 size sits within the G-series 200/300/400/600 range, and the family offers alternative port sizes, G (BSPP) or NPT thread options, automatic or manual drains, a 5 um element (code W), and external round gauges in MPa, psi or bar scales. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm the flow and 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.

Feeding filtered, low-pressure regulated air to the clamp and hold-down cylinders on a carton-sealing line, with the 1/2 in NPT ports matching the main drop leg.
Conditioning the supply to low-pressure air knives that dry bottles after rinsing, where the 40 um element keeps water and debris out of the nozzles.
Regulating supply pressure to pneumatic grippers and pick-and-place actuators on an automotive assembly cell, with the square MPa gauge giving operators a local set-point readout.
Size steps through 200, 300, 400 and 600, so choose the GFR400 with its 1/2 in NPT ports when your pipework and demand sit at that level; because flow is published as curves rather than a single rating, send us your requirement and we will confirm the fit before you order. The drain on this unit is the differential-pressure type, which bleeds the bowl as air passes; automatic (A) and manual (M) drains are order options where the duty suits them better. The 40 um element is the standard grade, with a 5 um element (code W) for finer protection. The embedded square gauge reads in MPa, and psi or bar scales plus an external round gauge can be ordered. Thread here is NPT; PT is the standard and G (BSPP) is also a catalogue option. A mounting bracket is included. This is the low-pressure regulator type, so tell us your working pressure and we will confirm the regulation range from the datasheet.
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 GFR400 series as curves rather than a single rated number, so we do not quote a figure here. Send us your line pressure, port size and air demand, and we will confirm the flow from the datasheet before you order.
The L in the code selects the low-pressure regulator variant, intended for set points below the standard type's range; the exact regulation range for this variant is not published, so we confirm it from the datasheet on request. The drain is the differential-pressure type, which bleeds the bowl automatically as air flows, with automatic and manual drains available as order options.
