Airtac GFR Filter Regulator GFR300C10F1K
The AirTAC GFR Filter Regulator GFR300C10F1K 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 GFR300C10F1K
The GFR300C10F1K is an AirTAC filter regulator: filtration and pressure regulation in one body, with a reverse (check) valve fitted, so air passes in the working direction and reverse flow back toward the supply side is blocked. It has a PT3/8 port, the standard 40 um element, a differential-pressure drain in the polycarbonate bowl and an embedded square gauge on an MPa scale. Setting range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure 1.0 MPa (145 psi), temperature -5 to 70 C non-freezing.
A genuine AirTAC part in the 300 size of the G series (sizes 200, 300, 400 and 600, larger means larger ports). The same configuration can be ordered without the check valve, with a 5 um (W) element, with automatic or manual drain, or with G (BSPP) or NPT threads. Flow for this series is published as curves, not a single rating, so ask us to confirm the datasheet figures for your circuit.

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.
Size Class

- 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 GFR300C10F1K Is Used
Weld-cell fixture clamping circuit
Regulates and cleans the air to robot-weld-cell clamps, with the fitted check valve blocking reverse flow so the fixture circuit does not feed back toward the supply side during shutdown or supply-side changes.
Assembly-station actuator manifold
Feeds the manifold serving the air cylinders and grippers on a manual assembly station: the 40 um element keeps moisture and particles out of the valves, the square MPa gauge gives the operator a local set-point, and the check valve holds the circuit against reverse flow.
Air-knife blow-off branch
Conditions and regulates the branch feeding air-knife blow-off nozzles on a filling line, where the check valve prevents downstream air from pushing back through the regulator toward the header.
Is the Airtac GFR Filter Regulator GFR300C10F1K the Right Unit?
This unit is the 300 size with a PT3/8 port and the K option, which adds a reverse (check) valve to the standard filter regulator - choose it where the downstream circuit must not feed back toward the supply side. Other real choices in the family: drain type (differential-pressure here, automatic A or manual M), filter grade (40 um standard, 5 um with W), gauge scale (MPa here; psi, bar and an external round gauge are options), and G or NPT thread instead of PT. Flow is published as curves rather than a single rated number, so ask us to confirm sizing 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 GFR300C10F1K FAQ
There is no single rated flow figure: AirTAC publishes performance for the G series as flow curves. Send us your operating pressure and required demand and we will confirm the figures from the datasheet so you can size the unit correctly.
K specifies that a reverse (check) valve is fitted, so air flows through the unit in the working direction and reverse flow is blocked. In every other respect it matches the standard GFR300 in PT3/8 with a 40 um element, differential-pressure drain and square MPa gauge.
