The AirTAC GFR400C15MLJC2TK AirTAC Filter Regulator 1/2in NPT 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 GFR400C15MLJC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a drain bowl but no lubricator. This size 400 unit is threaded NPT1/2 (1/2 in), carries the standard 40 um filter element, and has a manual-drain bowl in PC (polycarbonate). It is the low-pressure regulator type, and this configuration comes with a round psi gauge and a built-in check (reverse-flow) 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 in, and options that include manual, automatic 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 an optional mounting bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Clean, regulated low-pressure air to the clamp and sealing cylinders on a packaging line's case sealer, with the manual drain emptied as part of the shift checklist.
Filtering and regulating the pilot air feeding pneumatic rack-and-pinion actuators on a treatment-plant valve manifold, with the check valve blocking reverse flow at the unit.
Conditioned air for the diverter and pusher gates on a distribution-centre sortation conveyor, where the 40 um element protects the directional valves downstream.
Size and port are the first choice: GFR sizes 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at size 400 with a 1/2 in NPT port - match the step to the air demand of the circuit and ask us to check the flow curve before ordering. Drain type is a real decision: manual (as here) means an operator drains the bowl, while automatic and differential-pressure drains remove condensate without attention. Filter grade is 40 um as standard; choose code W for a 5 um element where finer particulate protection is needed. Gauges are embedded square as standard or external round, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as the AirTAC standard, with G (BSPP) and NPT as order options, and a bracket is optional (not fitted here). As a low-pressure type regulator, its adjustment range is not published in the data we hold, so we confirm the exact figures from the datasheet 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 as curves, not as a single rated number, so we do not quote a figure here. Tell us your operating pressure and air demand and we will confirm the flow from the datasheet on request.
The manual drain means an operator opens the drain at the bottom of the PC bowl to release collected condensate; automatic and differential-pressure drains are available on the family if unattended draining is preferred. The L in the code marks the low-pressure regulator type, set up for lower downstream pressures than the standard version; its exact adjustment range is not published in the data we hold, so we confirm it from the datasheet on request.
