The AirTAC GFR400C15MC2 AirTAC Filter Regulator PT1/2, psi Gauge 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 GFR400C15MC2 is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 400 unit has a 1/2 in PT1/2 port, a 40 um standard filter element and a manual drain, so condensate is released by opening the drain when you choose rather than automatically. Outlet pressure is set across the 0.05-0.9 MPa (7-130 psi) manual-drain range, and this configuration is fitted with the external round gauge scaled in psi so operators can read and adjust setting pressure directly. A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual draining, an optional 5 um (code W) element, square or round gauges with MPa, psi or bar scales, G or NPT thread options and bracket choices. 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.

Clean, regulated air feeding clamps and tool-change cylinders on a machining centre, where the psi gauge lets setters verify clamp pressure at the 1/2 in drop and the manual drain is opened at shift start.
Supplying carton-sealing and case-erector cylinders along a packaging conveyor, with the filter stopping pipe-scale and condensate reaching the valves and the regulator holding a steady setting for consistent stroke timing.
A filtered, adjustable air source for pneumatic test rigs and laboratory fixtures, where the round psi gauge gives a clear readout of the applied pressure and the manual drain suits intermittent, supervised use.
Start with the port step: size 400 with a PT1/2 port suits lines plumbed at 1/2 in, and larger sizes carry more flow - match the size to the air demand of the circuit rather than upsizing blindly. Choose the drain next: this unit is manual-drain, which gives the widest 0.05-0.9 MPa regulation range but relies on someone opening the drain; automatic or differential-pressure draining suits unattended installations. The 40 um element is the standard grade; specify the 5 um W option where downstream equipment needs finer filtration. Gauge choices are the embedded square type or the external round type fitted here, in MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Flow for these units is published as curves, not a single rating, so 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. 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 GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The M in the code selects the manual drain: condensate collected in the bowl is released by opening the drain by hand. It also allows the widest regulation range for this family, 0.05-0.9 MPa (7-130 psi). If the installation runs unattended, ask about the automatic or differential-pressure drain versions instead.
