Airtac GFR Filter Regulator GFR300C08AJC1W
The AirTAC GFR Filter Regulator GFR300C08AJC1W 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 GFR300C08AJC1W
AirTAC's GFR series combines a filter and a pressure regulator in one body: this unit carries the 5 um (W) element with a drain bowl to remove water and fine particulate from compressed air, and the regulator section sets downstream pressure over 0.15-0.9 MPa (20-130 psi) on the automatic-drain version. This GFR300C08AJC1W is the size 300 frame with PT1/4 (1/4 in.) ports, an automatic drain, a round external pressure gauge on the MPa scale, and no mounting bracket (J). The bowl on size 300 is polycarbonate (PC).
It is a genuine AirTAC part from the G series, which spans sizes 200 to 600 with ports from 1/8 in. to 1 in., PT as the standard thread and G (BSPP) or NPT as catalogue options. Medium is compressed air only; maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C. Flow is published as curves rather than a single rating, so we confirm datasheet figures for your duty 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.

| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| C0 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class

- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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 GFR300C08AJC1W Is Used
Laboratory pneumatic fixture supply
Feeds clean, regulated air to clamping fixtures on a test bench; the 5 um element suits instruments and fine components that do not tolerate moisture carryover.
Pneumatic screwdriver stations
Supplies regulated air to shut-off screwdrivers on an assembly line, where drier, finer-filtered air protects the clutch and helps torque repeatability.
Bottling line rinse blow-off
Filters and regulates the air driving rinse blow-off nozzles on a bottling line, keeping fine particles and water out of container interiors before filling.
Is the Airtac GFR Filter Regulator GFR300C08AJC1W the Right Unit?
The grade choice is the headline here: the standard element is 40 um, while the W code selects this finer 5 um element for applications that cannot tolerate fine carryover. The other decodable choices are size and port (this is the 300 frame on PT1/4), drain type (automatic as coded; manual or differential-pressure also exist), gauge style and scale (round, MPa here), bracket or bracketless (J, bracketless), and thread (PT standard; G and NPT orderable). Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 GFR300C08AJC1W FAQ
AirTAC does not publish a single rated flow for this unit - performance is given as flow curves instead. Tell us your supply pressure and air consumption and we will confirm the sizing from the datasheet on request.
The standard 40 um element suits general plant air; the W code in this model selects the 5 um element for fine components, spray finishing and instrumentation. Both fit the same size 300 body, and the rest of the decode - PT1/4 ports, automatic drain, MPa round gauge - is unchanged. We can help confirm the right grade from the datasheet on request.
