Airtac GFR Filter Regulator GFR300C15N
The AirTAC Airtac GFR Filter Regulator GFR300C15N 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 GFR300C15N
The GFR300C15N is an AirTAC filter regulator: water and particulate removal plus pressure regulation in one body with a drain bowl, and no lubricator stage. This one is the 300 size with a 1/2 in PT port, the standard differential-pressure drain, the standard 40 um element and no reverse valve. The N at the end of the code means it is supplied without a pressure gauge. 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 runs from 200 to 600 frames, with manual or automatic drains, a 5 um element option, gauge options, reverse valves and G (BSPP) or NPT threads listed in the catalogue. Flow is published as curves rather than a single rating, so we confirm figures and the 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 GFR300C15N Is Used
Conveyor actuation on a bottling line
Feeds the air cylinders that stop, divert and index bottles between filler and capper, giving the line a single point where air is filtered to 40 um and held at a set pressure.
Plant air drop above a production cell
Installed at the wall drop feeding a general production cell, so every cylinder, air gun and blow-off nozzle downstream draws regulated air instead of raw header pressure.
Pilot supply for pneumatic control valves
Conditions the pilot air for solenoid-operated control valves on a utility skid, keeping grit and water out of the pilot stage while holding a steady set pressure.
Is the Airtac GFR Filter Regulator GFR300C15N the Right Unit?
Match the frame to the job: 200, 300, 400 and 600 sizes step up in port and air demand, and this 300 unit carries a 1/2 in PT port. The differential-pressure drain is the series default and pairs with the 0.15-0.9 MPa (20-130 psi) regulating range; manual-drain versions reach down to 0.05 MPa if you need it. The standard 40 um element covers general plant air, while a 5 um element is available for finer duties. No gauge is fitted with this code, and an external round gauge can be specified from the options. PT is the standard thread, with G and NPT as catalogue choices. Ask us to confirm flow against your application before ordering, since the datasheet gives curves, not a single rating.
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 GFR300C15N FAQ
AirTAC publishes flow for this series as performance curves rather than one rated number, so we do not state a figure on the page. Send us your line pressure, port size and downstream demand and we will confirm the flow data from the datasheet on request.
No. The N at the end of the code means the unit is supplied without a gauge. AirTAC lists an external round pressure gauge as an option for this family, so you can add one when specifying the order if you want a local pressure reading at the unit.
