Airtac GFR Filter Regulator GFR300C10MF1K
The AirTAC Airtac GFR Filter Regulator GFR300C10MF1K 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 GFR300C10MF1K
This GFR300C10MF1K is an AirTAC G-series filter regulator with a check (reverse) valve fitted: filtration and pressure regulation in one body, with a drain bowl but no lubricator. It is a size 300 unit with a 3/8 in G (BSPP) port, a manual-drain polycarbonate bowl, a 40 um standard filter element and an embedded square gauge on the MPa scale. Manual drain gives a 0.05-0.9 MPa (7-130 psi) regulating range; maximum inlet pressure is 1.0 MPa (145 psi), medium is compressed air at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. Across the GFR family (sizes 200/300/400/600) you can order automatic, manual or differential-pressure drains, 40 um or 5 um elements, the check-valve K option used here, square or external round gauges in MPa, psi or bar, and PT (standard), G or NPT threads. Flow is published as curves, not a single rated figure - ask us to confirm the datasheet and sizing 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.
Model Code: Airtac GFR Filter Regulator GFR300C10MF1K
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.
Size Class

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 GFR300C10MF1K Is Used
Clamp fixture hold circuit
Regulates supply to pneumatic clamps on a welding or machining fixture, with the check valve helping the clamped side hold its setting if the upstream branch is vented.
Compressor room branch take-off
Installed on a drop from the receiver line, it filters and regulates air for a dedicated machine bay while the check valve stops cross-feed between parallel branches.
Assembly station torque tool feed
Prepares air for piston-driven nutrunners and pressing tools at an assembly cell, giving the station its own set pressure independent of neighbours on the same main.
Is the Airtac GFR Filter Regulator GFR300C10MF1K the Right Unit?
Choose this K-coded unit over the plain GFR300C10MF1 when the downstream circuit must not back-feed through the regulator - the fitted check valve holds the set pressure downstream if upstream supply is interrupted. Everything else is the same decode: size 300, 3/8 in G port, manual drain (regulating range 0.05-0.9 MPa / 7-130 psi), 40 um element, embedded square MPa gauge. If you need finer filtration, the W code gives a 5 um element; other drain types, gauge scales (psi/bar, round external gauge) and NPT or PT threads are catalogue options, and the mounting bracket is included as standard.
On sizing: flow for this series appears as curves, not one rated number, so let us check the size 300 curve against your pressure and consumption before you order.
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 GFR300C10MF1K FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so there is no one number we can state. Tell us your working pressure and air demand and we will confirm the size 300 sizing from the datasheet curves on request.
It is the factory-fitted check (reverse) valve: air flows out normally, but the valve blocks reverse flow back through the regulator. Use this code when a downstream circuit must keep its set pressure if the upstream side is vented; the plain code without K omits the valve.
