The AirTAC GFR40015JF2WK AirTAC Filter Regulator PT1/2 5 um 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 GFR40015JF2WK is a size 400 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 1/2 in PT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential is sufficient, and an embedded square gauge reading in psi. A reverse/check valve is fitted, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um filtration, gauge style and scale, and G or NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application on request.

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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 on the air drop feeding a CNC machining centre: the 5 um element protects solenoid valves and actuators from water and fine particulate while the regulator holds a steady setting for clamping and tool-change circuits.
Conditioning and regulation of the air feeding pneumatic cylinders on a carton-forming and sealing conveyor line, with the check valve holding the downstream setting if upstream supply dips and the psi gauge giving operators a local reading.
Filtered, regulated air to a laboratory analyser or instrument enclosure purge circuit, where the finer 5 um grade and a stable, gauge-monitored pressure protect sensitive instrumentation from moisture and debris in the shop air.
Size 400 with a 1/2 in PT port suits lines running higher air demand than the 200/300 step; match the size to your required flow, which we confirm from the published curves before you order. The 5 um element (code W) is the finer choice over the 40 um standard where downstream equipment is more sensitive to particulate. The differential-pressure drain is the default and needs no manual attention under normal duty; automatic (A) and manual (M) drains are catalogue options on this family. The fitted square gauge reads in psi; round external gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT available to order, and this unit is supplied without a bracket.
Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and we will confirm the datasheet flow figures against it on request before you order.
The W in the code GFR40015JF2WK selects the 5 um filter element instead of the 40 um standard, and the K selects a fitted reverse/check valve that helps hold the regulated downstream pressure if the upstream supply drops. Both are catalogue options on the GFR400; the 40 um grade and no-valve versions are available as alternative codes.
