The AirTAC GFR40015JF2WGK AirTAC Filter Regulator G1/2, 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 GFR40015JF2WGK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, 5 um filtration (the finer W grade, versus the 40 um standard element), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough, an embedded square gauge scaled in psi, and a built-in reverse (check) valve that holds downstream pressure if the upstream supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing). The polycarbonate bowl suits the size 400 frame; only the size 600 units use an aluminium alloy bowl. No mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain, filter-grade, gauge-scale, thread (PT standard, G and NPT as order options) and bracket choices. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm the datasheet and flow data 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 spray-booth and paint-pump air drops on a finishing line: the 5 um element takes fine particulate and condensed water out of the supply before the regulator sets a stable gun pressure, and the check valve keeps the circuit from dumping if the main header dips.
Conditioning air to a cartoning or wrapping machine's cylinder bank: one G1/2 connection filters and regulates the whole machine feed, the psi-scaled square gauge gives operators a setpoint they can read at a glance, and the differential-pressure drain keeps condensate off the valves.
Mounted at the inlet of an OEM machine's air manifold: the filter regulator sets the circuit pressure after the 5 um element cleans it, the reverse valve holds the panel's pressure through brief supply interruptions, and the no-bracket configuration suits direct manifold mounting.
Size 400 with a 1/2 inch port sits in the upper-middle of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - we will check the catalogue flow curves against your demand if you send us the figures. This unit has the 5 um element (code W); choose the 40 um standard grade if coarse protection is enough, or add a finer downstream filter for sensitive equipment. The differential-pressure drain needs no daily attention but relies on airflow across the element to purge; pick an automatic drain (code A) for low-flow duty or a manual drain (code M) if you want drain control in the operator's hands. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. The trailing G sets the G (BSPP) thread - PT is the standard thread and NPT is orderable as an option - and the J code means no mounting bracket, so plan your own panel or manifold fixing. Before ordering, ask us to confirm sizing: flow is published as curves, not a single rating.
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 GFR flow as curves in the catalogue, not as a single rated number, so we do not quote a l/min or SCFM figure for this unit. Send us your required flow and working pressure and we will confirm the datasheet and flow-curve data for the size 400, 1/2 inch port configuration before you order.
The W in the code selects the optional 5 um filtration grade instead of the 40 um standard element, giving finer protection for downstream equipment. The K at the end of the code means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is interrupted. Both are decodable choices - the 40 um grade and no-valve versions are available under other codes in the same series.
