The AirTAC GFR400C10MLF2WG AirTAC Filter Regulator G3/8 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 GFR400C10MLF2WG is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a G3/8 (BSPP) port on the size-400 body, a 5 um filter element (code W), a manual drain, the low-pressure regulator type, and a built-in square gauge reading in psi. The bowl is metal, a mounting bracket is included, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family runs from size 200 to 600 with port options in PT (the AirTAC standard), G and NPT, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge or no-gauge builds. Flow for the family is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Pneumatic clamps and swing cylinders on machining fixtures often work at reduced set pressures; this unit filters the shop air to 5 um and regulates it down, with the psi gauge giving the operator a direct setting reference.
Benches running pneumatic instruments and test rigs need clean, low-pressure air; the 5 um element protects sensitive devices and the manual drain suits intermittent, supervised use.
Pick-and-place and sealing actuators on packaging lines run from a filtered, regulated drop; the size-400 G3/8 body slots into the machine's air-prep position and the included bracket fixes it to the frame.
Choose the size by the port step and the flow your line needs: this unit is size 400 with a G3/8 port, while smaller 200/300 and larger 600 bodies step the port and flow capacity up or down. Drain choice matters in service: manual (as here) means an operator opens the drain periodically; automatic and differential-pressure drains discharge condensate without attention. The filter grade is 5 um here (code W) against the 40 um standard element. The square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this unit - PT is the AirTAC standard and NPT is an order option - and a mounting bracket is included. One honest note: this is the low-pressure (L) regulator type and its exact setting range is not published, and flow for the whole family is published only as curves, so ask us to confirm both 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 family as curves, not as a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm sizing from the datasheet on request.
This unit carries the L code, so its regulator is the low-pressure type intended for reduced set pressures; the exact range for this variant is not published. Standard (non-L) GFR regulators have published ranges, and we can confirm the low-pressure setting range from the datasheet on request.
