The AirTAC GFR40015F1TK AirTAC Filter Regulator NPT1/2 40 um 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 PT1/2" 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 GFR40015F1TK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is a 1/2 in NPT-port unit with a 40 um element, a differential-pressure drain, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). An embedded square gauge scaled in MPa is fitted, a reverse/check valve (code K) holds the downstream setting, and a mounting bracket is included. The polycarbonate bowl suits the 400 size, with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with ports from 1/8 to 1 in, PT (standard), G or NPT threads, 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, and square or external round gauges scaled in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Point-of-use filter regulator ahead of a CNC machine tool's pneumatic clamps and tool-change cylinders, cleaning water and particles from the air and holding a steady setting for repeatable clamping.
Feeding cleaned, regulated air to case-erector and carton-sealing cylinders on a packaging conveyor, with the check valve holding the downstream setting through supply dips.
Mounted in the air-preparation panel of a paint booth, filtering condensate and grit from the supply and regulating pressure to the spray-gun actuation valves and fixture cylinders.
Choose the size and port step (200 through 600, 1/8 to 1 in) against the air demand of your circuit; this 400-size unit carries a 1/2 in NPT port. Select the drain: differential-pressure on this model (expels condensate as the pressure drop across the element builds), automatic (A) for unattended duty, or manual (M) for scheduled checks. Pick the filter grade - 40 um standard here, or 5 um (code W) where finer protection is needed - and the gauge scale (MPa, psi or bar; this unit is square, MPa). The thread on this model is NPT; PT is the standard and G is also available to order. A mounting bracket is included. Because flow is published as curves rather than one rated number, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this 1/2 in unit on request.
This model's blank drain code is the differential-pressure type: condensate is expelled when the pressure drop across the 40 um element builds high enough. Choose code A for fully automatic draining, or code M for a manual drain you operate during scheduled checks.
