The AirTAC GFR400C15JF1WT AirTAC Filter Regulator NPT1/2 5 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 GFR400C15JF1WT is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a drain bowl and no lubricator. This size 400 unit is ordered with a 1/2 in NPT port, the optional 5 um filter element (the 40 um standard element is also available in the series), a differential-pressure drain, a square pressure gauge with MPa scale, a standard regulator, and no bracket or check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The polycarbonate bowl suits visual level-of-condensate checks.
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600) in the GFR filter-regulator family, with larger sizes carrying larger ports and more flow capacity. Across the series you can order automatic or manual drain instead of the differential-pressure drain, the 5 um element, gauge scales in MPa, psi or bar, an external round gauge, a reverse/check valve, a bracket, and G (BSPP) or NPT thread where PT is the standard thread. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm flow and 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.

Filtered, regulated air to clamp and press cylinders on an assembly line, holding a set pressure downstream even as compressor header pressure swings.
Moisture-reduced air at a fixed pressure to positioners and pneumatic control valves on a process skid, with the 5 um element guarding fine internal passages.
Supply air for pick-and-place and indexing modules on an electronics or packaging machine, where clean, regulated air protects sealing surfaces and cycle consistency.
Step through the real, decodable choices. Size and port: 200/300/400/600, with port stepping from 1/8 in up to 1 in - pick the size whose flow curve covers your demand at your working pressure; this unit is the size 400 body with a 1/2 in NPT port. Drain: differential-pressure (fitted here, venting condensate on pressure drop), automatic for unattended duty, or manual where you prefer operator-controlled draining. Filter grade: 40 um is the series standard; the W code on this model selects the 5 um element for finer particulate removal. Gauge: the square gauge with MPa scale is fitted; psi or bar scales and an external round gauge are order options. Thread: PT is the standard thread, and G (BSPP) or NPT are catalogue options - this unit is ordered with NPT. Bracket: optional; not included on this code. AirTAC publishes flow 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 flow for the GFR400 as curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and full datasheet figures on request.
The W in the code selects the optional 5 um element for finer particulate removal; 40 um is the series standard. Both grades fit the same GFR400 filter regulator, and the choice does not change the 1/2 in port, the 1.0 MPa maximum inlet pressure or the 0.15-0.9 MPa regulation range.
