Airtac GFR Filter Regulator GFR300C10MF1
The AirTAC GFR Filter Regulator GFR300C10MF1 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 GFR300C10MF1
This GFR300C10MF1 is an AirTAC G-series filter regulator: filtration and pressure regulation combined in a single 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 pressure gauge on the MPa scale. Because the drain is manual, the regulating range is 0.05-0.9 MPa (7-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the working medium is compressed air at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series filter regulator family runs from size 200 up to 600, with automatic, manual or differential-pressure drains, 40 um or optional 5 um elements, an optional check valve, square or external round gauges in MPa, psi or bar scales, and PT (the standard thread), G or NPT as catalogue thread options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

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 GFR Filter Regulator GFR300C10MF1 Is Used
Bench pneumatic punch press
Sits in the airline ahead of the directional valve and cylinder on a small punch press, giving filtered, regulated air for consistent stamping force; the manual bowl is bled at shift start.
Carton sealing and packaging line
Prepares the supply to sealing cylinders and pop-up stops on a carton sealer, holding a steady setting so case eject timing stays repeatable through the shift.
General plant airline branch
Mounted on a drop from the workshop ring main, it strips water and pipe scale from the compressed air and sets a fixed working pressure for air tools and blow-off stations.
Is the Airtac GFR Filter Regulator GFR300C10MF1 the Right Unit?
Size 300 with a 3/8 in G port sits mid-range in the GFR family (200/300/400/600); step up or down a size if your line's air demand sits beyond what the size 300 flow curve delivers. The manual drain (M) here gives the widest regulating range, 0.05-0.9 MPa (7-130 psi), and suits points someone bleeds off on a maintenance routine; automatic or differential-pressure drain codes exist for unattended bowls. The standard element is 40 um - choose the W code for a 5 um element where finer filtration is needed. The embedded square gauge reads MPa; psi or bar scales, and an external round gauge, are orderable options. G (BSPP) is a catalogue thread option - PT is the standard thread on this series and NPT is also available. A mounting bracket is included unless you order a J code.
One honest note before you order: flow is published as curves, not a single rating, so ask us to confirm the size 300 curve against your application's pressure and consumption.
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 GFR300C10MF1 FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and expected air consumption and we will confirm the sizing against the datasheet flow curves on request before you order.
A manual drain means someone opens the bowl drain at intervals, and in return the regulating range widens to 0.05-0.9 MPa (7-130 psi). If the bowl is in an awkward or unattended spot, the automatic (A) or differential-pressure (blank) drain codes are the better choice - same body, different drain.
