The AirTAC GFR400C15MJF1T 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 GFR400C15MJF1T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds a steady regulated downstream pressure, in a single body. This configuration is the 400 size with 1/2 in NPT ports, a manual-drain bowl, a 40 um filter element, an embedded square gauge reading in MPa, and no mounting bracket. The manual drain means the bowl is emptied by hand during routine checks, and the regulation range for this unit is 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus choices of drain type, 40 um or 5 um filtration, gauge scale, bracket and reverse/check valve. Flow 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.

Feeding valve manifolds on a carton-forming and palletizing line: filtered, regulated 1/2 in air to actuators and grippers, with the square gauge giving the setter a direct MPa reading at the drop.
A workholding clamp circuit on a machining cell, where the regulator sets clamping pressure anywhere in the 0.05-0.9 MPa range and the 40 um element keeps debris out of the clamp cylinder and valve.
Air for pushers and stop gates on a bottling conveyor: the manual-drain bowl is emptied during shift checks, keeping condensed water out of the gate cylinders and control valves.
Step up to the 400 size when your line's flow demand and 1/2 in piping call for it; the family steps 200 / 300 / 400 / 600. This unit already fixes several choices: manual drain (empty by hand - simple, but it needs operator attention), 40 um standard filtration (5 um is available as code W), a square gauge on an MPa scale, NPT thread, no bracket and no reverse/check valve. If you would prefer automatic drainage, a 5 um element, a psi or bar gauge scale or a bracket, ask us for the matching GFR400 code.
Flow for the GFR400 is published as curves, not a single rating - send us your flow and pressure targets 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 rather than a single rated figure, so we do not quote one number. Tell us your flow and downstream pressure targets and we will confirm the datasheet figures for this exact unit before you order.
The M in the code means the bowl is drained by hand - simple and dependable, but someone has to open the drain during routine checks. The GFR family also offers automatic and differential-pressure drains; if you would rather not rely on operator attention, ask us for the equivalent automatic-drain GFR400 model.
