The AirTAC GFR400C15AJF2W AirTAC Filter Regulator 1/2 in PT, 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 GFR400C15AJF2W is an AirTAC GFR400 filter regulator: a 400-size unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded PT1/2 (1/2 in, PT standard), carries the 5 um filter element (code W, against the 40 um standard), drains condensate automatically, and is fitted with the embedded square gauge scaled in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the unit is supplied without a mounting bracket.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers drain, filter-grade, gauge, thread (PT, G, NPT) and bracket options; the GFC two-unit and GC three-unit combinations add lubrication where a full F.R.L. is required. Flow is published as curves rather than a single rating, 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.

Feeding clean, regulated air to a machine tool's pneumatic functions - tool clamps, tool changers and coolant valves - where the 5 um element and automatic drain keep moisture and chips-borne debris out of the valve stack.
Regulating air to pick-and-place and sealing cylinders on a bottling or cartoning line, with the automatic drain clearing condensate between shifts so no one has to bleed bowls by hand.
Supplying regulated air to pneumatic nutrunners, clamps and press stations at an assembly plant, where the 5 um grade helps protect precision tools from water and particulate carryover.
Size steps from 200 to 600 as flow demand grows; this 400 size takes a 1/2 in PT port. Choose the drain to match service: automatic (this unit, for unattended condensate removal), manual, or differential-pressure. Filtration is 40 um standard or 5 um with the W code (this unit). Gauges are the embedded square type with MPa, psi or bar scales, or an optional external round gauge; a reverse/check valve and mounting bracket are order options, and PT is standard with G and NPT available to order. 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.
Flow for the GFR400 is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - port size, downstream demand and working pressure - and we will confirm the relevant datasheet figures on request before you order.
This unit carries drain code A, which expels collected condensate automatically instead of waiting for a manual bleed; the family also offers manual (M) and differential-pressure (blank) drains. For automatic and differential-pressure drains the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
