The AirTAC GFR40015F2WT AirTAC Filter Regulator NPT1/2 in, 5 um, psi is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" 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 GFR40015F2WT 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 5 um filter element (the finer of the two published grades), a differential-pressure drain, and a fitted embedded square gauge scaled in psi. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600) with port options from 1/8 to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, MPa/psi/bar gauge scales, and G or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm 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.

Point-of-use conditioning ahead of a machining centre's pneumatic tool-changer and clamping circuits: clean, regulated air at a set pressure protects spindles' actuation and holding fixtures from moisture and overpressure.
Filtering and regulating the air feeding conveyor diverters, case erectors and carton-closing cylinders on a packaging line, with the 5 um element guarding directional valves from fine particulate.
A regulated, filtered drop at an assembly bench supplying air tools, clamps and small actuators, with the psi gauge letting operators verify and set the station pressure at a glance.
Size 400 with a 1/2 in NPT port suits lines where the required flow sits at the upper-middle of the G-series range; step up to size 600 or down to size 300 depending on the curve your demand needs. Choose the 5 um element (this model) when downstream equipment needs finer particulate removal than the 40 um standard grade. The differential-pressure drain bleeds accumulated condensate automatically as pressure differential builds - pick an automatic drain for unattended duty or a manual drain for simple, low-duty points. The psi-scaled square gauge is embedded as standard; an external round gauge in MPa, psi or bar is optional. PT is the standard thread; G (BSPP) and NPT (this model) are catalogue options to order. A mounting bracket is included.
Before ordering, ask us to confirm sizing: flow is published as curves, not a single rating, so we will check the datasheet against your air demand.
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 number here. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet before you order.
The W in the code GFR40015F2WT selects the 5 um filter element instead of the 40 um standard grade, and the F2 selects the embedded square gauge scaled in psi. Both are catalogue choices: you can order the same size 400 filter regulator with the 40 um grade and an MPa or bar scale if that suits your plant standard.
