AirTAC GFR300-10 Filter Regulator (GFR30010F1K)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010F1K) 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 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.

About the AirTAC GFR300-10 Filter Regulator (GFR30010F1K)
The AirTAC GFR30010F1K is a G-series filter regulator fitted with a reverse (check) valve, which holds the downstream setting if upstream supply is interrupted. It filters and regulates in one body with the standard 40 um element, a differential-pressure drain on the polycarbonate bowl, and the embedded square gauge in MPa. The 3/8 in PT port matches the 300 size, and the regulator adjusts 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part in the GFR300 series, offered in 200 to 600 sizes with G/NPT/PT threads and automatic or manual drain options. The K check-valve variant is a catalogue choice for circuits that must hold pressure upstream. Flow figures appear only as curves, so we confirm datasheet values on request.

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.

Where the AirTAC GFR300-10 Filter Regulator (GFR30010F1K) Is Used
Isolation hold on valve manifolds
Keeps a regulated setpoint on a valve-manifold branch even when the upstream supply is shut, so actuator positions do not drift during maintenance on the main line.
Clamping fixture hold circuits
Maintains clamp pressure on a machining fixture while the upstream air is bled or switched, with the check valve preventing backflow out of the circuit.
Safety interlock air supply
Supplies filtered, regulated air to interlocked guarding actuators on a press line, holding the setpoint through brief supply interruptions and reading it on the MPa gauge.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010F1K) the Right Unit?
Specify K when the circuit must keep its regulated pressure during a supply drop - otherwise the same unit without K, the GFR30010F1, is the choice. Port sizing follows your piping: 3/8 in on the 300 body sits between the 1/4 in (200) and 1/2 in (400) steps. This unit uses the 40 um standard element; the 5 um W grade exists for finer circuits. The embedded square MPa gauge saves panel space versus the round external option. PT is standard, G and NPT are catalogue options, and the bracket is included.
Flow is published as curves, not a single rating, so ask us to confirm sizing for your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR300-10 Filter Regulator (GFR30010F1K) FAQ
We do not quote a single rated flow because AirTAC publishes this series as flow curves. Give us your operating pressure and demand and we will confirm the datasheet figure for this 3/8 in, 300-size unit with check valve on request.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply drops. If your circuit does not need that hold function, the GFR30010F1 without K is identical otherwise: 40 um element, 3/8 in PT, MPa square gauge.
