The AirTAC GFR30015JC2WK 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 GFR30015JC2WK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is built for 1/2 in PT ports, carries the 5 um element (code W) instead of the 40 um standard, drains condensate by differential pressure from its polycarbonate bowl, and is fitted with a round gauge reading in psi plus a reverse (check) valve. No mounting bracket is included with this code.
It is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for automatic or manual drains, 40 um or 5 um filtration, gauge type and scale, and G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet.

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 tool-change cylinders and workpiece clamps on a CNC cell: the 5 um element protects directional valves from particles and water, while the regulator holds a steady clamping pressure and the check valve holds it if shop supply dips.
Mounted ahead of stopper, pusher and divertor cylinders on a bottling or carton line: clean, regulated air keeps stroke timing consistent through the shift, and the differential-pressure drain clears condensate without a manual drain round.
Conditioning the supply to a valve island driving grippers and weld-gun clamps in a weld cell: the 5 um grade suits sensitive pilot circuits, the psi round gauge gives operators a local set-point readout, and the PT1/2 port matches the cell's main drop.
Choose the size by the flow your line needs: 300 sits mid-range, with 200 for lighter duty and 400 or 600 for higher demand - we can check the published curve against your application. This code fixes the 1/2 in PT port; G (BSPP) and NPT are order options. Drain is differential pressure here; automatic (A) or manual (M) versions exist if you prefer. The 5 um element suits air feeding valves and instruments; the 40 um standard is fine for general shop air. The round gauge reads psi (MPa or bar scales are available), and the K option adds a check valve to hold downstream pressure if supply drops. No bracket is fitted with this code. 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.
We do not quote a single rated flow figure, because AirTAC publishes flow for this series as curves, not as one number. Send us your line's air demand and we will confirm from the datasheet whether the GFR300 at PT1/2 is correctly sized before you order.
K means a reverse (check) valve is fitted: if upstream supply fails, it holds the regulated downstream pressure instead of letting it escape back toward the inlet. W is the 5 um filter element, one grade finer than the 40 um standard. This unit also has a differential-pressure drain, a round psi gauge, no bracket, and a PT1/2 port.
