The AirTAC GFR400C15JF3T AirTAC Filter Regulator NPT1/2, 40 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 AirTAC GFR400C15JF3T is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size 400 unit is configured with 1/2 in NPT ports, the standard 40 um filter element, a differential-pressure drain (the bowl drains automatically as the pressure differential changes - no manual draining routine), and a fitted embedded square gauge scaled in bar. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and no reverse/check valve is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing). The bowl on this 400 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of 40 um or 5 um (code W) filtration, differential-pressure, automatic or manual drains, and gauge or no-gauge configurations. Flow is published as curves rather than a single rated figure, so ask us and we will 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.

Mounted at the drop feeding a CNC machining centre's pneumatic valves and tool-change cylinders, this unit cleans condensed water and swarf-laden air out of the supply and holds a steady regulated pressure so clamping and tool-change sequences repeat consistently shift after shift.
Installed on the air feed to a packaging line's conveyor stops, diverters and case-closing cylinders, the filter stage keeps moisture and particles out of the directional valves while the regulator sets the pressure the line was designed around, with the bar-scale gauge giving operators a visible setpoint.
Fitted at take-off points on a factory ring main serving multiple workstations, this filter regulator conditions the shared compressed air locally - differential-pressure draining handles condensate without operator intervention, and each take-off can be set to the pressure its own tools and actuators need.
Work through the decodable choices in order. Size and port: 200/300/400/600 step up in port and flow capacity, so match the size to the air demand of the circuit downstream - this unit is size 400 with 1/2 in NPT ports. Drain type: differential-pressure (this configuration) drains with the pressure differential, automatic (code A) drains continuously, and manual (code M) drains only when operated - pick per how often the line runs and how much condensate it carries. Filter grade: 40 um is standard; specify 5 um (code W) if downstream components need finer protection. Gauge: this unit carries the embedded square gauge scaled in bar; MPa and psi scales and an external round gauge are options. Thread: NPT here, with PT as the standard and G (BSPP) available to order. A mounting bracket can be included or omitted (code J omits it, as here).
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm the datasheet and check the sizing against your required flow before you commit.
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 we do not quote a rated flow, Cv or SCFM number for this unit. Send us your application - port size, downstream demand and line pressure - and we will confirm the datasheet and check the sizing against your required flow on request before you order.
This configuration uses the differential-pressure drain, the default for the GFR family: condensate in the bowl is discharged as the pressure differential across the element changes, with no operator action needed. If your line runs intermittently or you prefer controlled draining, the same size 400 unit can be ordered with an automatic drain (code A) or a manual drain (code M) - note that the manual-drain version has a wider regulator adjustment range starting at 0.05 MPa, while the differential-pressure and automatic versions start at 0.15 MPa (20-130 psi).
