The AirTAC GFR400C15MLJF2WGK AirTAC Filter Regulator G1/2 5 um 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 GFR400C15MLJF2WGK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built around a G1/2 (BSPP) port, the finer 5 um filter element, a manual drain on the metal bowl, and the low-pressure regulator type - its exact set-point range is not published in the catalogue, so we confirm it on request. An embedded square gauge scaled in psi is fitted, a reverse/check valve holds downstream pressure if the supply is interrupted, and the unit is supplied without a mounting bracket. 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 can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges scaled in MPa, psi or bar, G, NPT or PT threads, and with or without a bracket. Flow 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.

Feeds the clamp circuit of a CNC fixture with 5 um filtered air at a low set point, while the fitted check valve holds the clamp if the main supply is interrupted.
Supplies the guide and hold-down cylinders on a packaging line with clean, low-pressure regulated air, protecting the actuators from water and fine particulate.
Sets the low pressure for air knives blowing debris off containers ahead of filling, with the 5 um element keeping the blow-off nozzles from clogging.
Size and port step up with flow demand: this unit is size 400 with a 1/2 inch G-thread port; smaller 200/300 bodies take 1/8 to 3/8 inch ports and size 600 goes up to 1 inch. The real choices are: drain type (manual here - you bleed the bowl by hand; automatic or differential-pressure drains discharge without attention), filter grade (5 um fitted here versus the 40 um standard), gauge (embedded square gauge scaled in psi; MPa or bar scales and an external round gauge are options), thread (G here; PT is the standard thread and NPT is an order option), bracket (none fitted), and regulator type (low-pressure here versus standard). Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm this is the right size 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 rated flow number is quoted here. Send us your required flow and working pressure and we will confirm against the datasheet curves that size 400 with the 1/2 inch port suits your application.
This configuration carries the L code, so the regulator is the low-pressure type rather than the standard version. The catalogue does not publish an exact set-point range for this variant, so we confirm the range on request. Other published figures still apply: maximum inlet pressure is 1.0 MPa (145 psi), the temperature range is -5 to 70 C non-freezing, and the filter element is 5 um.
