Airtac GFR Filter Regulator GFR300C10MNW
The AirTAC Airtac GFR Filter Regulator GFR300C10MNW 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 GFR300C10MNW
GFR300C10MNW is a genuine AirTAC GFR-series filter regulator: filtration and pressure regulation in one body, size 300 with a 3/8 in PT port. The W suffix selects the finer 5 um filter element in place of the standard 40 um, M gives a manual drain on the polycarbonate bowl, N omits the gauge, and the mounting bracket is 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 range is -5 to 70 C (non-freezing).
The G series offers sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and 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.

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 GFR300C10MNW Is Used
Laboratory and analytical instrumentation
Filtered, regulated supply air to lab instruments and pneumatic samplers that are specified for cleaner air than the standard 40 um grade provides.
Spray finishing stations
Regulated atomizing air to a spray-gun station, with the 5 um element trimming particulate ahead of the gun and the manual drain used to clear the bowl between sessions.
Instrument air in monitoring cabinets
Supplying purged enclosures and gas-analyser cabinets where the specifier calls for 5 um filtered air held at a fixed regulated pressure.
Is the Airtac GFR Filter Regulator GFR300C10MNW the Right Unit?
Size 300 with a 3/8 in PT port is the mid-range step; go smaller or larger (200/400/600) to match the line. Choose this W version when the equipment downstream is specified for 5 um filtration rather than the standard 40 um grade. The M manual drain means the polycarbonate bowl is drained by hand on a routine - pick automatic (A) or differential-pressure draining for unattended points. No gauge is fitted (N); gauge variants with MPa, psi or bar scales exist in the family. PT is the standard thread, with G and NPT as catalogue options, and a bracket is included. Flow is published as curves, not a single rating, so send us your flow requirement 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 GFR300C10MNW FAQ
There is no single rated figure to quote - AirTAC publishes G-series flow as curves. Share your inlet pressure and required downstream flow and we will confirm the datasheet curve and check that size 300 suits your application before you order.
The standard 40 um element covers general plant air. Select the W suffix, as on this GFR300C10MNW, when the equipment manufacturer or process specification calls for 5 um filtration. Everything else in the code - size 300, 3/8 in PT port, manual drain, bracket included, no gauge - stays the same.
