The AirTAC GFR30015JC2WG 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 GFR300 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This GFR30015JC2WG is built with a G1/2 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate as the pressure drop across the element rises, and an external round gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part in the 300 size of the G-series range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. The 300-size bowl is polycarbonate (PC); only the 600 size uses aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing). 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.

Placed ahead of a weld-cell robot's pneumatic grippers, it filters the supply down to 5 um and holds a steady set pressure so grip force does not wander between cycles.
On a distribution-centre conveyor, it conditions the air feeding diverter and pusher cylinders, with the psi gauge letting line staff check the set point at a glance.
Feeding purge and actuation air to a lab analyser cabinet, the 5 um element protects sensitive pneumatic components while the regulator keeps supply pressure inside the instrument's window.
Size and port step up with flow demand: 200, 300, 400 and 600, with ports from 1/8 in to 1 in; this unit is 300 size with a G1/2 port. The choices encoded here matter in practice: the 5 um element (code W) suits points that need finer air than the standard 40 um grade; the differential-pressure drain is the default and suits a steady, always-on supply, with automatic (A) or manual (M) drains orderable as alternatives; the round psi gauge is the external option against the embedded square gauge (MPa, psi or bar scales); and the thread is G (BSPP), with PT as the standard and NPT available to order. The J suffix means no mounting bracket is included.
Flow is published as curves, not a single rating, so 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. 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 GFR300 as curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your application's flow and pressure requirements and we will confirm the datasheet figures and check the sizing before you order.
The W in this code selects the 5 um grade against the 40 um standard. Choose 5 um where downstream valves, cylinders or instruments need finer air; 40 um suits general plant supply. Both grades are available across the GFR range, and the differential-pressure drain works with either.
