The AirTAC GFR40015C2WG 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 GFR40015C2WG is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body, with no lubricator. It removes water and particulate from compressed air through a 5 um element (the finer of the two catalogue grades) and holds downstream pressure within a 0.15-0.9 MPa (20-130 psi) adjustment range. This configuration is sized for a 1/2 inch port with G (BSPP) thread, carries a differential-pressure drain that bleeds condensate automatically as flow passes through, and is fitted with an external round gauge reading in psi. The polycarbonate bowl suits the non-freezing -5 to 70 C operating window, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and each size can be ordered with manual or automatic drain, a 40 um or 5 um element, different gauge scales, G or NPT thread in place of the PT standard, and with or without a bracket. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

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 the tool-change clamps and pneumatic actuators on a CNC machining centre, where the 5 um element protects precision valves from particulate and the psi gauge lets setters verify clamp pressure at a glance.
Conditioning the air drop that serves a carton-forming and sealing line, combining water removal and steady regulated pressure in one body so sealing cylinders cycle consistently through a full shift without a separate regulator.
Supplying the pop-up diverters, stoppers and gate cylinders on a distribution conveyor system, where the differential-pressure drain keeps condensate out of the loop automatically and the bracket mounts the unit beside the manifold.
Start with the port step: this unit is the 400 size at 1/2 inch, one step up from the 300 series, so choose it when your line's flow demand sits above what a 3/8 inch unit carries - and ask us to confirm the exact flow curve before ordering, since AirTAC publishes flow as curves rather than a single rating. The 5 um element here is the finer option against the 40 um standard; pick it when downstream valves or instruments need cleaner air, accepting that the finer element loads faster. The differential-pressure drain is the default: it purges condensate using the pressure drop across the element, with no operator action, whereas manual drain needs periodic bleeding and automatic drain works on a timer-free float. The round psi gauge suits US-facing panels; square gauges and MPa or bar scales are orderable. Thread is G (BSPP) here - PT is the catalogue standard and NPT is an option, so match it to your fittings, and the included bracket simplifies panel or frame mounting.
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 for the GFR400 series as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line's air demand and we will confirm the curve and check the sizing against your application before you order - the datasheet figures are available on request.
The W in the code GFR40015C2WG selects the 5 um filtration grade instead of the 40 um standard, giving finer protection for downstream valves and instruments. The blank drain position selects the differential-pressure drain, the catalogue default, which purges collected condensate using the pressure drop across the element with no manual bleeding. A manual (M) or automatic (A) drain can be ordered instead if your maintenance routine prefers it.
