Airtac GFR Filter Regulator GFR300C08MC1W
The AirTAC GFR Filter Regulator GFR300C08MC1W 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 GFR300C08MC1W
GFR300C08MC1W is an AirTAC G-series filter regulator: filtration and pressure regulation in one body, for compressed air only. This 300-size unit carries a PT1/4 port, a manual-drain PC (polycarbonate) bowl, the finer 5 um filter element (W option), and an external round pressure gauge on the MPa scale. Regulation range with manual drain is 0.05-0.9 MPa (7-130 psi); max working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series runs from size 200 to 600 with ports from 1/8 to 1 inch and G (BSPP) or NPT thread options; automatic and differential-pressure drains, the standard 40 um element, a check-valve option and other gauge choices sit on neighbouring codes. AirTAC publishes flow as curves rather than a single rating, so we confirm sizing and datasheet figures on request.

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 GFR300C08MC1W Is Used
Paint spray booth gun feed
Conditioning air to spray guns and air-assisted applicators in a finishing line, where the 5 um element catches finer particulate before it reaches the fluid tip.
Pneumatic instrumentation on a control skid
Regulating supply to panel-mounted indicators and transducer circuits, with the external round gauge readable at the panel door and the manual drain bled during rounds.
Assembly-bench air tool supply
Feeding nutrunners and air ratchets at a manual assembly bench, with the regulator set once and the 5 um element protecting the tools' air passages.
Is the Airtac GFR Filter Regulator GFR300C08MC1W the Right Unit?
Step up or down a size (200/300/400/600) to match the pipe port and duty of your line; 300 corresponds to the 1/4 inch PT port on this code. Manual drain suits points where an operator bleeds the bowl on a schedule; automatic or differential-pressure drains suit unattended installs. The W in this code selects the 5 um element instead of the standard 40 um grade - specify W where finer filtration is called for. The gauge is the external round type on MPa; square-face and psi/bar scales exist on other codes. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 GFR300C08MC1W FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so quoting one number would be misleading. Send us your line pressure and air demand and we will confirm the sizing from the datasheet curves on request.
W selects the finer 5 um filter element instead of the standard 40 um grade. Both are validated options on the GFR series - choose 5 um where the downstream equipment is sensitive to finer particulate, and stay with 40 um for general plant air.
