The AirTAC GFR40015AJC1TK AirTAC Filter Regulator NPT1/2 Auto Drain 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 automatic 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 GFR40015AJC1TK is a size 400 filter regulator that removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration has a 1/2 in NPT port, a standard 40 um filter element, an automatic drain that expels collected condensate without manual attention, a round pressure gauge scaled in MPa, and a built-in reverse (check) valve. It is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

Feeds filtered, pressure-controlled air to tool-clamp and pallet-change circuits on a machining centre, with the automatic drain keeping condensate out of the valves between shifts.
Conditions the air feeding carton-forming and case-sealing cylinders on a packaging line, holding a steady setting to the downstream regulators of each station.
Serves the pusher and stopper cylinders along a conveyor system, where the check valve helps hold the set pressure against upstream fluctuations.
Choose the size and port step against the air demand of the line: this unit is size 400 with a 1/2 in NPT port, and larger sizes carry larger ports and more flow. The 40 um element is the standard grade; a 5 um element (code W) is available if finer filtration is needed. The automatic drain suits unattended installations, while manual and differential-pressure drain versions exist in the series. The round MPa gauge is fitted here; square embedded gauges and psi or bar scales are alternatives. PT is the standard thread, with G and NPT as order options, and the bracket is omitted on this code (J).
Because flow is published as curves rather than a single rated figure, send us your application details 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. 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 line pressure, set pressure and air demand and we will confirm the sizing against the datasheet on request.
The A in the code selects the automatic drain, which expels collected condensate by itself instead of relying on manual draining. The K selects a built-in reverse (check) valve. Both are decodable options on GFR filter regulators, alongside manual or differential-pressure drains and units without the check valve.
