The AirTAC GFR400C15JF1T 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 GFR400C15JF1T is a size 400 filter regulator: it removes water and particulate from compressed air and sets a stable downstream pressure in one body. This configuration has a 1/2 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure drop across the element is high enough, and a square pressure gauge with an MPa scale so the set pressure can be read and adjusted at a glance. No mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing); the regulation range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um element option (code W), gauge scale options and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 a workshop pneumatic press or clamp station: the 1/2 in port carries the volume the press cycle needs, the 40 um element keeps pipe scale and rust out of the cylinder valves, and the regulator holds a consistent working pressure so stroke force stays repeatable.
Supplying the air drop on a carton sealing or case packing line: clean, regulated air keeps the vacuum generators and pick-and-place cylinders behaving consistently through long shifts, and the differential-pressure drain handles condensate without an operator walking the line.
Conditioning the air feed to spray or coating equipment: water and particulate in the supply cause fisheyes and finish defects, so the filter section protects the finish while the regulator pins atomizing pressure at the setting the process calls for.
Start with the port and size: this unit steps up to 1/2 in NPT in the size 400 body, the right choice when your downstream air demand is larger than a 3/8 in line comfortably serves. Size up if your flow curve needs it - we can confirm the published curve against your consumption. The 40 um element is the standard grade for general plant air; choose the 5 um W option only where finer pre-filtration matters. The differential-pressure drain here is the fit-and-forget choice: it discharges condensate on pressure differential with no operator input, while a manual drain (code M) suits low-moisture or periodically attended installations.
The fitted square gauge reads in MPa; psi and bar scales are available if your team works in those units. PT is the standard thread and G (BSPP) or NPT are order options - this unit is specified with NPT. A mounting bracket can be ordered if you want the unit secured independent of the piping. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing 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 G-series flow as curves rather than a single rated figure, so there is no one rated flow number we can quote for this 1/2 in, size 400 unit. Tell us your working pressure and air consumption and we will confirm the datasheet curve and sizing for your application on request.
The differential-pressure drain on this unit discharges collected condensate automatically whenever the pressure drop across the 40 um element rises enough to open it - no manual intervention. If your installation is attended periodically or the air is very dry, a manual drain (code M) is a simpler alternative; an automatic drain (code A) is available where continuous unattended drainage is preferred.
