The AirTAC GFR400C10MC2T | AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10MC2T is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is a 400-size unit with a 3/8 in NPT port, 40 um standard filtration, a manual drain and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). The 400 size uses a polycarbonate bowl, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including automatic or differential-pressure drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding clean, regulated air to the valves and actuators on a CNC machining centre. The 40 um element keeps swarf-laden shop air out of the machine's pneumatic circuit, the manual drain lets an operator bleed accumulated water at shift start, and the psi gauge matches standard US shop gauges.
Regulating supply pressure to the cylinders that fold, press and seal cartons on a packaging line. One filter regulator ahead of the manifold keeps water and pipe scale out of the valves while holding a steady setpoint so cylinder action stays repeatable through the shift.
Supplying filtered, regulated air to the grippers and clamps on a robotic welding cell. The manual drain suits a cell visited at every maintenance round, and the 3/8 in NPT port drops straight into typical US-cell air drops without adapters.
Choose the size by port and flow: 200, 300, 400 and 600 step up from 1/8 to 1 in, and this 400 unit carries a 3/8 in port. Drain type is a real choice: manual (this unit, code M) needs an operator to open the bowl drain, while automatic and differential-pressure versions drain without attention. Filtration is 40 um standard; specify code W for the 5 um element where finer protection is needed. Gauges come with MPa, psi or bar scales - this unit has a round psi gauge - and threads can be ordered in PT (the standard), G (BSPP) or NPT. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, 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 GFR400 as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant flow and sizing figures from the datasheet on request.
The M in the code means a manual drain: an operator opens the drain to expel the water collected in the bowl, which suits attended lines with regular checks. If the unit will run unattended, the family also offers automatic and differential-pressure drains. With a manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
