The AirTAC Airtac GFR Filter Regulator GFR300C10JF1WK is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 GFR300C10JF1WK combines three suffix options on the AirTAC G-series filter regulator: the fine 5 um element (W), a fitted reverse (check) valve (K), and the embedded square gauge scaled in MPa (F1). Filtration and regulation share one body, with no lubricator. This configuration is the 300 size with 3/8 in PT ports and a differential-pressure drain; the J suffix means it is ordered without a mounting bracket. Adjustment range is 0.15-0.9 MPa (20-130 psi), max inlet pressure 1.0 MPa (145 psi), temperature -5 to 70 C, non-freezing. The 300-size bowl is polycarbonate (PC).
This is a genuine AirTAC part for the US market. The same GFR300 frame is available with a 40 um element, without the check valve, in 200/400/600 sizes, with 1/8 to 1 in ports, G(BSPP) and NPT threads, and automatic or manual drains. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow figures on request before you order.

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.

Protects a safety-related clamp or gate circuit on an automated line: the 5 um element conditions the air while the check valve helps the circuit keep its set pressure if the supply fails upstream.
Feeds finely filtered, regulated air to the solenoid bank of an automated leak or functional test station, with the reverse valve isolating the station from backflow between cycles.
Supplies clean, regulated pilot air to the control valves of a pneumatic assembly press, with the check valve guarding the pilot line against reverse pressure surges.
This code suits circuits that need both finer filtration and backflow protection: the W element filters to 5 um while the K check valve helps the downstream side hold its regulated pressure through an upstream supply interruption. The port step is 3/8 in PT on the 300 frame - move to 400/600 for more flow or 200 for compact lines. Drain is differential-pressure as standard, with automatic (A) and manual (M) variants available (manual drain widens the range to 0.05-0.9 MPa / 7-130 psi). The embedded square MPa gauge is included, an external round gauge is optional, and a bracket can be added by dropping the J suffix. G-series flow is published as curves, not a single rating, so ask us to confirm sizing 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.
Yes - on request. AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a rated flow number. Send your application's flow and pressure requirements and we will confirm the datasheet curve for this exact configuration before you order.
No. GFR is a two-function unit: filtration and regulation in one body, with no lubricator. If your circuit also needs oil-mist lubrication, the GFC two-unit set (filter regulator plus lubricator) or the GC three-unit F.R.L. combination covers that; for filter-plus-regulator only, this GFR300C10JF1WK is the matching choice.
