The AirTAC GFR400C15JF2 AirTAC Filter Regulator PT1/2, 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 GFR400C15JF2 is a filter regulator: one body that first removes water and particulate from compressed air, then regulates downstream pressure. This 400-size unit is fitted with a 1/2 in PT port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, and the embedded square gauge is scaled in psi so operators can read and set line pressure directly. No mounting bracket is included with this configuration and no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR400 series. The GFR filter-regulator family spans 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 available to order, plus choices of drain type, 40 um or 5 um filtration, gauge scale, and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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 clean, regulated air to tool-clamp cylinders and pneumatic chucks on a CNC machining centre, where the 1/2 in port suits the main drop line and the psi-scaled square gauge lets setters verify clamp pressure at a glance.
Conditioning the air supply to carton-forming and case-sealing cylinders on a packaging conveyor line, with the 40 um element stopping pipe-scale and condensed water from jamming valve spools downstream.
Serving as the point-of-use filter regulator on a factory assembly-cell air drop, holding a stable working pressure for air tools and fixtures while the differential-pressure drain clears condensate without daily manual bleeding.
Choosing within the GFR family comes down to a few decodable decisions. Size and port step up together - 200 through 600 - so pick the size whose published flow curve covers your air demand at acceptable pressure drop; for a 1/2 in line this 400-size unit is the natural match. Drain type: differential-pressure (this unit) drains condensate automatically on pressure differential, an automatic drain (code A) drains continuously, and a manual drain (code M) needs operator attention. Filter grade: 40 um is the standard element; specify 5 um (code W) where downstream equipment needs finer protection. Gauge: square embedded gauge is standard on this unit with a psi scale; MPa or bar scales and an external round gauge are alternatives. Thread: PT is standard here, with G (BSPP) and NPT as order options. Bracket: this configuration omits it, so plan your own mounting if needed.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated number, so we cannot quote a rated flow figure. Send us your application details and we will confirm the flow and datasheet figures 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact 400-size, 1/2 in PT unit on request before you order.
This configuration has the differential-pressure drain: condensate collected in the bowl is discharged automatically whenever the pressure differential across the 40 um element rises enough, so no manual bleeding is needed in normal service. If your application needs continuous draining or a manual drain instead, those are alternative drain codes within the same GFR400 series.
