Airtac GFR Filter Regulator GFR300C15AC1WK
The AirTAC GFR Filter Regulator GFR300C15AC1WK 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.

About the Airtac GFR Filter Regulator GFR300C15AC1WK
The GFR series combines compressed-air filtration and pressure regulation in a single body. This GFR300C15AC1WK is a size 300 unit with a PT1/2 port, a 5 um fine-filtration element (W), an automatic drain that ejects collected condensate without operator attention, a round external pressure gauge with MPa scale, and a reverse (check) valve fitted to hold downstream pressure when supply is lost. Maximum working pressure is 1.0 MPa (145 psi); regulation range for the automatic-drain version is 0.15-0.9 MPa (20-130 psi); temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size frame.
This is a genuine AirTAC part. The G series is offered in sizes 200, 300, 400 and 600 with 1/8 in to 1 in ports, drain choices (differential-pressure, automatic, manual), 40 um standard or 5 um fine elements, gauge and scale options, PT, G or NPT threads, and check-valve or low-pressure variants. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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.

| C1 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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.
Size Class

- GFR300PT1/4" - PT1/2"
- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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.

Where the Airtac GFR Filter Regulator GFR300C15AC1WK Is Used
CNC machine tool air supply
Feeding filtered, regulated air to a machining centre's tool-change cylinders and air clamps, with the 5 um element protecting precision valve internals and the check valve holding set pressure through brief supply dips.
Carton sealing line
Conditioning the air feeding the downholder and tape-head cylinders on a packaging line, where automatic drain keeps condensate out of the actuators during long unattended shifts.
Panel-mounted pneumatic control circuits
Mounted ahead of directional valves and air piloting circuits in a control panel, delivering a stable set pressure shown on the round MPa gauge and shielded from backflow by the check valve.
Is the Airtac GFR Filter Regulator GFR300C15AC1WK the Right Unit?
Size 300 with a PT1/2 port is a mid-range frame: step up to 400 or 600 for larger ports and higher flow, or down to 200 for compact lines. The 5 um element (W) suits instruments and finer pneumatic components; the 40 um standard element protects general cylinders and valves. Automatic drain (A) is the low-maintenance choice for unmanned or hard-to-reach installations. This unit carries a round MPa gauge; square gauges and psi/bar scales are orderable alternatives. PT is the standard thread; G (BSPP) and NPT are catalogue options. A bracket can be omitted with the J variant. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR Filter Regulator GFR300C15AC1WK FAQ
AirTAC publishes flow for the GFR300 as curves, not as a single rated figure, so no single number can be quoted here. Tell us your downstream consumption and line pressure and we will confirm the correct sizing from the datasheet on request before you order.
The A code fits an automatic drain that purges the bowl without manual attention - useful for enclosed machines or high installations. The W code selects the 5 um fine element instead of the standard 40 um, for lines feeding sensitive components. Both choices are made at order stage within the same GFR300 body.
