Airtac GFR Filter Regulator GFR300C15NW
The AirTAC Airtac GFR Filter Regulator GFR300C15NW 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 GFR300C15NW
The GFR300C15NW is an AirTAC filter regulator: water and particulate removal plus pressure regulation in a single body with a drain bowl, and no lubricator stage. This version is the 300 size with a 1/2 in PT port, the standard differential-pressure drain and the fine 5 um filter element instead of the standard 40 um. The N in the code means it is supplied without a pressure gauge, and no reverse valve is fitted. Output is adjustable from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the medium is compressed air only.
It is a genuine AirTAC part rated -5 to 70 C (non-freezing), with a polycarbonate (PC) bowl at this 300 size and a mounting bracket included. The G-series family spans 200, 300, 400 and 600 sizes, with manual or automatic drains, gauge options, reverse valves and G (BSPP) or NPT threads in the catalogue. Flow is published only as curves, so we confirm figures and the full datasheet 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 GFR300C15NW Is Used
Pick-and-place handling on an electronics assembly cell
Feeds the vacuum ejectors and small guiding cylinders on a pick-and-place gantry, where the 5 um element helps keep fine contamination away from the ejector and valve seats.
Instrument air inside a laboratory enclosure
Conditions the compressed air feeding lab bench instruments and purging lines in an analytical or test lab, with 5 um filtration and a fixed regulated pressure at the enclosure inlet.
Control air for a printing press console
Supplies the pneumatic control circuit behind a printing press console - clutch, brake and register cylinders - where finer filtration protects the small control valves doing the modulation.
Is the Airtac GFR Filter Regulator GFR300C15NW the Right Unit?
Choose the frame first: 200 to 600 sizes step up in port and air demand, and this 300 unit carries a 1/2 in PT port. The W in the code selects the 5 um element - pick it when pilot valves, precision cylinders or instruments downstream need finer filtration than the standard 40 um, keeping in mind a finer element needs more attention to drain condition. Drain is the differential-pressure default with the 0.15-0.9 MPa (20-130 psi) regulating range; manual-drain versions start at 0.05 MPa. No gauge is fitted, and an external round gauge is a catalogue option. PT is the standard thread, with G and NPT available. Since flow is given as curves rather than a single rating, ask us to confirm sizing for 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 GFR300C15NW FAQ
AirTAC does not publish a single rated flow figure for this series; flow is given as performance curves. Tell us your working pressure, port size and the air demand of the equipment downstream, and we will confirm the sizing data from the datasheet on request.
The W in this code selects the 5 um element, which suits duties with sensitive pilot valves, precision cylinders or instruments downstream. The standard 40 um element is the usual choice for general plant air on cylinders and tools. Both are catalogue options across the GF, GFR, GFC and GC families, so you can step between them per location.
