The AirTAC GFR400C15MLJC2GK AirTAC Filter Regulator G1/2, Low-Pressure 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 AirTAC GFR400 series combines water and particulate filtration with pressure regulation in a single body. This configuration is the 400 size with a G1/2 (BSPP) port, a manual drain on the polycarbonate (PC) bowl, and the standard 40 um filter element. The regulator is the low-pressure type (its exact setting range is not published; we confirm it from the datasheet on request), and the unit carries a round pressure gauge reading in psi plus a built-in reverse (check) valve. No mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options that include automatic, manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads to order. Flow for this series 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.

Filtered, regulated air to clamping cylinders on a fixture line, with the built-in check valve in the circuit and the psi gauge giving operators a direct readout at the setpoint.
Conditioning the air feed to a laboratory or QC test bench where the regulator is set below standard ranges and a round psi gauge is preferred for readout.
Supplying filtered, regulated air to diverters and stopper cylinders along a packaging conveyor, with the manual drain suiting an attended shift.
Pick the size step (200/300/400/600) and port against the air demand of the circuit; this 400-size unit takes a 1/2 in port, and larger sizes carry more flow. Drain choice matters: this unit has a manual drain, which needs someone to bleed the bowl, while automatic and differential-pressure versions discharge condensate on their own. The element here is the standard 40 um grade; specify code W if the job needs 5 um filtration. Gauge style and scale (MPa, psi or bar), thread (PT is the standard; G or NPT are order options) and bracket are all selectable, and the low-pressure regulator type is the right pick where the circuit runs at reduced settings.
Because AirTAC publishes flow only as curves, not a single rated figure, send us your flow and pressure requirements and we will confirm this model 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 GFR series as curves rather than a single rated figure, so no single number is quoted here. Send us your required flow and working pressure and we will confirm this model against the datasheet before you order.
This unit is coded M for a manual drain: condensate is released by opening the drain by hand, which suits attended installations. Automatic (code A) and differential-pressure (blank) drain versions of the same size are available if you prefer unattended draining.
