Airtac GFR Filter Regulator GFR300C10N
The AirTAC GFR Filter Regulator GFR300C10N 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 GFR300C10N
The AirTAC GFR family filters and regulates compressed air in a single body: the bowl collects water and particles for the drain to remove, while the adjusting knob sets the downstream pressure. This model is the 300 size with a PT3/8 port, the standard 40 um element and the default differential-pressure drain, and no pressure gauge is fitted. Maximum inlet pressure is 1.0 MPa (145 psi); with the differential-pressure drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part from the G series, spanning sizes 200 to 600 (1/8 in. to 1 in. ports) with 40 um or 5 um elements, differential-pressure, automatic or manual drains, and gauge or no-gauge variants. The 300 size carries a polycarbonate bowl and works on non-freezing compressed air from -5 to 70 C. Flow appears in the catalogue as curves rather than a single rated figure, so we confirm datasheet and flow 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 GFR300C10N Is Used
Stopper and gate cylinders on conveyors
Regulating the supply to stopper, lift and divert cylinders along a roller conveyor line, with the differential-pressure drain clearing bowl condensate as the line cycles.
Actuated ball-valve panels
Providing clean, regulated air to solenoid valves and quarter-turn actuators on a water or process skid, ahead of the valve manifold.
Assembly cell supply header
Serving as the point-of-use filter-regulator on the air drop feeding a small assembly cell's cylinders and air-operated fixtures.
Is the Airtac GFR Filter Regulator GFR300C10N the Right Unit?
Choose the frame by port and air demand: 200 = 1/4 in., 300 = 3/8 in., 400 = 1/2 in. and 600 upward, so the 300 sits mid-range. The blank drain code here is the differential-pressure type, which ejects condensate using the pressure differential across the unit; automatic (A) and manual (M) drain variants can be ordered if the bowl is mounted where a hand cannot reach. The standard element grade is 40 um, with 5 um (W) for finer duty, and no gauge is fitted in this code - gauge variants exist in the series. Thread is PT as standard with G (BSPP) and NPT as options, and the bracket is included unless J is specified.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your line conditions 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 GFR300C10N FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote a l/min or SCFM number here. Send us your inlet pressure and air demand and we will confirm the flow and sizing from the datasheet on request.
With no drain letter in the code, the unit carries the differential-pressure drain, which expels condensate from the bowl using the pressure differential across the regulator. Automatic (A) and manual (M) drain variants, 5 um elements and G or NPT threads can be ordered in the same series.
