The AirTAC GFR30010JF2WK AirTAC Filter Regulator PT3/8, 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 PT3/8" 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 GFR30010JF2WK is a GFR-series filter regulator: in one body it removes water and particulate from compressed air and holds downstream pressure steady. This size-300 unit is supplied with 3/8 in PT ports, the optional 5 um filter element (code W), a differential-pressure drain and a built-in check valve (code K) that helps keep the downstream circuit charged if upstream supply dips. The embedded square gauge reads in psi, and the polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, optional G or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um elements and MPa, psi or bar gauge scales. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet 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.

| 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.

Feeding a directional valve and clamp cylinder: the 5 um element protects the valve spool from water and fine dirt, the regulator holds the clamp set-point, and the check valve helps hold the circuit if upstream supply dips.
Conditioning air ahead of pick-and-place cylinders and ejectors on a carton packing machine, with the local psi gauge giving operators a visible set-point at the station.
Supplying spray guns on a paint line, where the 5 um grade keeps water and fine particulate out of the finish and the regulator pins gun pressure against supply swings.
Choose the size by the air consumption of the circuit: this 300 unit carries 3/8 in PT ports, one step up from the 200 series and one below the 400. The 5 um element (W code) suits valves, instruments and spray work that need finer air than the standard 40 um grade. The differential-pressure drain is the default and needs no separate drain fitting; automatic and manual drains are order options. The square gauge is set to psi here, with MPa and bar scales available, and an external round gauge can be ordered. The J code means no mounting bracket is fitted, though brackets are available, and the K code adds a check valve. Thread is PT as standard; G and NPT are order options. Because AirTAC publishes flow only as curves, not a single rating, send us your demand figures and we will confirm this unit is correctly sized before you order.
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 only as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The W code on this model orders the optional 5 um element, suited to valves, instruments and spray work. The standard GFR300 element is 40 um, and both grades are available across the family - just specify the code when ordering.
