The AirTAC GFR400C10MJF1T AirTAC Filter Regulator NPT3/8, Manual 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 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 GFR400C10MJF1T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This size 400 unit is threaded 3/8 in NPT, carries a 40 um filter element, and uses a manual drain, so the bowl is emptied by opening its drain valve during routine checks. The standard regulator covers 0.05-0.9 MPa (7-130 psi) and the fitted embedded square gauge reads outlet pressure in MPa.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional 5 um filtration (code W), automatic or differential-pressure drains, psi or bar gauge scales, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Filter and regulate the shop-air feed to a CNC machine's pneumatic circuit: clean, moisture-reduced air at a set pressure for tool-change cylinders and clamping actuation, with the MPa gauge giving operators a local pressure reference.
Condition the air feeding conveyor stoppers, pushers and divert gates on a packaging line, holding a stable set pressure so sorting and stopping actions repeat consistently through the shift.
Install at the take-off point where a factory ring main drops air to an assembly cell, filtering scale, rust and condensed water out of the distributed supply and regulating it to the pressure the cell's actuators were set up for.
Size 400 with a 3/8 in NPT port suits lines where the supply connection is 3/8 in; step up to size 600 or down to 300/200 if your piping and expected flow demand it. This configuration has a manual drain, which is the right choice when someone is already at the machine regularly; choose the automatic drain version where the unit is hard to reach. Filtration is the 40 um standard element; specify the 5 um (W) option only where downstream equipment needs finer air. The fitted square gauge reads in MPa, and psi or bar scales are available. Thread here is NPT; PT is the AirTAC standard and G (BSPP) can be ordered. No mounting bracket is included with this code (J).
Because AirTAC publishes flow only as curves and not as a single rated figure, we do not quote a flow number here. 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. 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 performance curves rather than a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the relevant flow data from the datasheet on request before you order.
The M in the code GFR400C10MJF1T specifies a manual drain: condensed water collects in the polycarbonate bowl and is released by opening the drain valve during routine checks. If the unit will be mounted where regular attention is impractical, the same filter regulator is available with an automatic drain or the differential-pressure drain as the order option.
