The AirTAC GFR400C10MLJC1TK AirTAC Filter Regulator NPT3/8 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 GFR400C10MLJC1TK is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a 3/8 in NPT port. This configuration carries a manual drain on the polycarbonate bowl, the standard 40 um filter element, the low-pressure regulator type, a round pressure gauge with MPa scale, and a built-in reverse (check) valve. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the service temperature range is -5 to 70 C (non-freezing). The exact regulation range for the low-pressure type is not published in the catalogue, so we confirm it on request.
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, manual or differential-pressure drains, a 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and mounting brackets. Because flow for this series is published as curves rather than a single rating, we confirm the datasheet and sizing figures for your application on request.

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.

Cleaning and regulating the supply to carton-sealing and wrapping machines whose cylinders run at reduced line pressure, with the built-in check valve holding the downstream circuit if the main supply dips.
Feeding gate, stopper and diverter cylinders along a conveyor line, where filtered air protects the valve seals and the low-pressure regulator type matches the gentle setting these actuators need.
Supplying bench-top apparatus and test rigs from a house compressed-air drop, with the 40 um element catching pipe-scale and the manual drain allowing the bowl to be bled at the end of each session.
Pick the size by port and duty: this unit is size 400 with a 3/8 in NPT port; sizes 200 and 300 suit lighter circuits, while size 600 (1/2 to 1 in ports) serves heavier demand - we check the published flow curves against your air consumption before you order. Drain type is a real choice: the manual drain here needs periodic bleeding and suits attended installations, while automatic (A) and differential-pressure (default) variants suit unattended lines. Filter grade is the 40 um standard; specify code W for the 5 um element where finer particulate capture matters. The round MPa gauge is fitted on this code; an embedded square gauge, or psi/bar scales, are the alternatives. Thread is NPT here, ordered as an option against the PT standard, with G (BSPP) also available. Brackets are optional and this code omits one; the low-pressure regulator type is selected where the downstream setting sits below the standard type's range - we confirm the exact range on request.
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 series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream set pressure and air demand, and we will confirm the flow and sizing from the datasheet before you order.
The M in the code specifies a manual drain: condensate collected in the bowl is bled by hand, which suits attended installations where someone checks the unit routinely. If the regulator sits in an unattended line, ask about the automatic (A) or differential-pressure (default) drain variants of the same series.
