The AirTAC GFR400C15MLJC2WT AirTAC Filter Regulator NPT1/2 5um 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 GFR400C15MLJC2WT is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 400-size unit is built with a 1/2 in NPT port, the 5 um filter element (the finer of the two published grades), a manual drain for controlled bowl blow-down, and the low-pressure regulator type - its exact adjustment range is not published, so we confirm it on request. A round pressure gauge scaled in psi is fitted, the polycarbonate bowl suits the -5 to 70 C (non-freezing) operating window, and maximum inlet pressure is 1.0 MPa (145 psi). No mounting bracket is included on this code.
This is a genuine AirTAC part. GFR filter regulators are published in 200, 300, 400 and 600 sizes covering 1/8 to 1 in ports, with a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet and sizing for your application.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.

Glue and coating circuits on carton-sealing lines often run at reduced pressure where a standard regulator set-point sits too high. This low-pressure type GFR supplies clean, regulated air in that reduced band, and the 5 um element protects the applicator valves from water and particulate.
Container handling on a filling line uses short air cylinders for diverters, stops and pushers. A filter regulator at each zone supplies clean, regulated air to those valves, and the manual drain lets line operators clear collected condensate at shift start.
Bench rigs that leak-test or cycle actuators need water- and particulate-free air at a set pressure. The 5 um element, round psi gauge and NPT1/2 connection suit a workshop supply manifold, and the manual drain suits intermittent, supervised use.
The decodable choices on this family are real and worth matching to the job. Size (200/300/400/600) and port (1/8 to 1 in) set the connection and follow the published flow curve, not a single rating. Drain type matters day to day: manual (this unit) means an operator opens the drain, automatic drains on collected condensate, and differential-pressure drains as the element loads up. Filter grade is 40 um standard or 5 um with the W code - this unit carries the 5 um element. Gauge is embedded square as standard with an optional external round gauge in MPa, psi or bar; this unit has the round psi gauge. Thread is PT as the catalogue standard with G and NPT as order options - this unit is NPT. Bracket is omitted on this code (J). Because flow is published as curves rather than one rated figure, send us your application and we will confirm sizing 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 GFR400 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and datasheet figures on request before you order.
This unit carries the M code: an operator opens the drain to expel collected water. The automatic drain (code A) discharges condensate on its own, and the differential-pressure drain (the blank default) releases when the element loads up. Manual suits supervised installations; choose automatic where the unit is rarely visited.
