The AirTAC GFR400C15MJC1WTK AirTAC Filter Regulator NPT1/2 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 GFR400C15MJC1WTK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built for a 1/2 in NPT port, carries the fine 5 um filter grade, drains collected water manually, and is fitted with a round pressure gauge on the MPa scale, a built-in reverse/check valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT as catalogue options), bracket, and reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the 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.

Mounted at the air inlet of a metal-fabrication stamping press, this unit removes water and fine particles from the shop air line and holds a steady, manually set pressure to the press cylinder, while the built-in check valve holds upstream settings if supply dips.
On a bottling or packaging conveyor, this filter regulator conditions the air feeding grippers, pushers and stopper cylinders, with the 5 um grade protecting tight-tolerance valve spools and the manual drain cleared during shift checks.
Feeding the pneumatic clamping and tool-change circuit of a CNC machining centre, this unit delivers filtered air at a regulated pressure set on the round MPa gauge, keeping workholding force consistent through the shift.
Size and port step up together: GFR sizes 200, 300, 400 and 600 cover 1/8 in to 1 in ports, so choose the size whose flow curve covers your demand at your working pressure. Drain is a real choice on this family: differential-pressure (the default), automatic (code A) or manual (code M) - this unit is manual, which suits points where an operator can bleed the bowl on a schedule. Filter grade is 40 um standard or 5 um (code W) - this unit carries the 5 um element for finer protection downstream. Gauges: an embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit has the round gauge on MPa. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order, and this unit is NPT. Bracket is included by default and code J deletes it - this unit has no bracket. 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 flow for the GFR400 as curves, not as a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the figures against the AirTAC datasheet on request before you order.
Code M means the bowl is drained by hand: an operator opens the drain valve to release collected water, which suits accessible mounting points on a scheduled maintenance round. The GFR400 is also available with automatic drain (code A) or the differential-pressure drain (the default); choose automatic where the unit is hard to reach or the line runs continuously. Note that the regulation range differs by drain type: this manual-drain unit adjusts from 0.05 to 0.9 MPa (7-130 psi).
