The AirTAC GFR400C15JF1TK AirTAC Filter Regulator NPT1/2 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 GFR400C15JF1TK is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1/2 in NPT port, a 40 um standard filter element, a differential-pressure drain, an embedded square pressure gauge scaled in MPa, a fitted reverse/check valve, and no mounting bracket. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this drain type, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). The polycarbonate bowl suits the size-400 frame.
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 include automatic or manual drains, a 5 um element (code W), psi or bar gauge scales, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket. Flow is published as curves rather than a single rated figure, 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.

Installed at the point of use ahead of a CNC machine's pneumatic clamps and tool-change cylinders, cleaning the shop air and holding a steady regulated pressure for repeatable clamping.
Feeding the cylinders and vacuum cups of a carton-sealing conveyor line, where the 1/2 in port serves the line's main drop and the check valve holds downstream pressure if the supply dips.
Conditioning and regulating the air feed to spray guns in a paint booth, removing water and pipe scale so finish quality is not spoiled by moisture or debris in the air stream.
Step up through sizes 200, 300, 400 and 600 to match the port and flow your line needs; this unit sits at size 400 with a 1/2 in port. Choose the drain to suit maintenance access: differential-pressure (this unit's default), automatic (A) for hands-off condensate removal, or manual (M). The 40 um element is standard; specify 5 um (code W) where finer filtration is required. Gauge scales can be ordered in MPa, psi or bar, and the thread can be G (BSPP) or NPT instead of the PT standard. Note this code carries no bracket (J), so plan a separate mounting if the installation needs one. Flow for the GFR series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow and we will confirm the sizing from the datasheet curves on request before you order.
The differential-pressure drain fitted here discharges condensate automatically when the pressure drop across the 40 um element rises, with no operator intervention. If you prefer a set schedule, order the automatic drain (code A); for full manual control, order the manual drain (code M). All three are catalogue options on the GFR400.
