The AirTAC GFR400C15JC1WT AirTAC Filter Regulator NPT 1/2 in 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 GFR400C15JC1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This size 400 unit is threaded NPT 1/2 in, carries the 5 um filter element (the finer of the two catalogue grades), drains condensate by differential pressure, and is fitted with an external round gauge scaled in MPa. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing). The bowl is polycarbonate (PC), and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include manual or automatic drains, the 40 um standard element, square or round gauges scaled in MPa, psi or bar, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeding pneumatic clamps and fixtures on a machining centre: the 5 um element helps keep scale and pipe debris out of the clamp cylinders while the regulator holds a steady clamping pressure at the fixture.
Supplying stoppers, pushers and diverters on a packaging conveyor line, where the differential-pressure drain clears the condensate that collects along long runs of downstream piping.
Point-of-use conditioning at a spray booth drop: the 5 um grade reduces particulate reaching the spray gun and the regulator sets a steady atomising pressure at the gun.
The real choices in this family are the size and port step, the drain, the filter grade, the gauge and the thread. Size 400 with a 1/2 in port suits lines with higher air demand than the 200/300 frames; match the frame to your flow requirement rather than to pipe size alone. Drain options are differential-pressure (this unit, which clears condensate as the pressure differential rises), fully automatic, or manual. The element here is 5 um (code W); the 40 um standard grade is available in the same frame if finer filtration is not required. Gauges come embedded square as standard with an optional external round gauge in MPa, psi or bar scales - this unit carries a round MPa gauge. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also offered, and a mounting bracket can be added.
Flow for the G-series is published as curves, not a single rated figure, so send us your application details 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 G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your inlet pressure, set pressure and expected air demand and we will confirm the flow from the datasheet for this exact model before you order.
The 40 um grade is the catalogue standard and suits general workshop air. Code W selects the 5 um element, the choice for applications such as precision cylinders, air tools with close tolerances, or point-of-use drops ahead of sensitive devices. This unit is supplied with the 5 um element; the standard grade is available in the same size 400 frame.
