The AirTAC GFR400C15JF2T AirTAC Filter Regulator, NPT 1/2 in 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 GFR400C15JF2T is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is the 400 size with 1/2 in NPT ports, the standard 40 um filter element and a differential-pressure drain that bleeds the bowl automatically as the pressure differential rises. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), the fitted embedded square gauge reads in psi, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC), and this code carries no mounting bracket and no reverse/check valve.
This is a genuine AirTAC part. The GFR series spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include a 5 um filter element (code W), automatic or manual drains, gauge scales in MPa, psi or bar, an external round gauge in place of the embedded square gauge, and G (BSPP) or NPT threads ordered in place of the PT standard. 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.

Point-of-use clean, regulated air for a CNC machining centre's tool clamps and chip-sweep cylinders, fed from a 1/2 in shop-air drop, with the psi gauge letting setters set and check working pressure at the cell.
Filtered, regulated air for the pick-and-place cylinders and sealing jaws on a carton forming and sealing line, with the 40 um element keeping water and debris out of the directional valves.
Regulated air to the diverter gates and stop cylinders on a conveyor sortation system, where the differential-pressure drain handles condensate without scheduled attention from maintenance staff.
Pick the size and port against the air demand of the line: this 400 unit carries 1/2 in NPT ports, and larger sizes in the series move more flow. Choose the drain to suit access: differential-pressure (this code) needs no operator attention, automatic (A) drains continuously, and manual (M) suits monitored installations - note the regulation range splits by drain type, 0.15-0.9 MPa (20-130 psi) here versus 0.05-0.9 MPa (7-130 psi) with a manual drain. The 40 um element is standard; specify W for the 5 um grade where finer filtration is needed. Gauge scale is selectable (MPa, psi or bar) and this code carries the embedded square gauge reading psi. Thread is NPT on this code; PT is the AirTAC standard and G (BSPP) is also available to order. Brackets are optional and not included in this code. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet 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 as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet figures for this 1/2 in unit before you order.
The blank drain position in this code means a differential-pressure drain: it bleeds accumulated condensate from the bowl automatically as the pressure differential across the filter rises, with no timer or operator attention. Automatic (code A) and manual (code M) drains are available on the same series.
