Airtac GFR Filter Regulator GFR300C10MN
The AirTAC Airtac GFR Filter Regulator GFR300C10MN 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 GFR300C10MN
GFR300C10MN is a genuine AirTAC GFR-series filter regulator: filtration of water and particulate plus pressure regulation in a single body, size 300 with a 3/8 in PT port. Here M selects a manual drain on the polycarbonate bowl, N omits the gauge, and the standard 40 um filter grade applies, with a mounting bracket included. With manual drain the regulating range is 0.05-0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi), the medium is compressed air, and the working temperature is -5 to 70 C (non-freezing).
The G family runs from sizes 200 to 600 with ports from 1/8 in to 1 in, and offers PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, bracket and gauge options. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for this exact code before you order.

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.

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 GFR300C10MN Is Used
Diverters and stoppers on bottling lines
Regulated air to the cylinders that stop, divert and index bottles along a filling line, with the bowl catching carryover water before it reaches the valve seals.
Pilot supply to automated ball valves
Feeding quarter-turn pneumatic actuators in a process plant, where the regulator holds the actuator supply at the pressure specified by the valve package.
Clamping circuits on welding fixtures
Air preparation for fixture clamps on a fabrication cell: filtered, regulated supply air so clamping pressure stays where the fixture design intends.
Is the Airtac GFR Filter Regulator GFR300C10MN the Right Unit?
Size 300 with a 3/8 in PT port is the middle step of the range; move to 200 for small drops or 400/600 when the line demands a larger port. The standard 40 um element suits general plant air where no special cleanliness grade is specified; specify the W suffix instead if you need 5 um. The M manual drain means the polycarbonate bowl is emptied by hand on a routine - choose automatic (A) or differential-pressure draining if the unit cannot be attended. No gauge is fitted (N); gauge variants can be ordered within the series. PT is the standard thread, with G and NPT as catalogue options. Flow is published as curves, not a single rating, so tell us your flow demand and we will confirm sizing against the datasheet 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 GFR300C10MN FAQ
Flow for the G series is published as curves, not as a single rated figure, so we do not state one number. Give us your inlet pressure and the flow your application needs and we will confirm the datasheet figures and correct sizing on request.
No. The N position means no gauge is fitted on this code. Gauge options exist across the GFR range, including the embedded square gauge and external round gauge types with MPa, psi or bar scales, on the corresponding suffixes.
