AirTAC GFR300-10 Filter Regulator (GFR30010AJNW)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010AJNW) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" ports, a automatic 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 GFR300-10 Filter Regulator (GFR30010AJNW)
GFR30010AJNW is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. This 300-size unit takes a PT3/8 port, the A code gives an automatic drain that clears condensate without manual attention, and the W code specifies the finer 5 um element instead of the standard 40 um, trimming smaller particles before air reaches the tools. No gauge is fitted and no check valve is included.
This is a genuine AirTAC part in the 200/300/400/600 G-series line, available in other ports and threads (G and NPT as catalogue options), other drain types, the standard 40 um grade and an optional gauge. Flow is published as curves rather than a single rating, so we confirm flow 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.
Model Code: AirTAC GFR300-10 Filter Regulator (GFR30010AJNW)
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (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. |
| W | Filtering grade 5 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 GFR300-10 Filter Regulator (GFR30010AJNW) Is Used
Automotive refinish booth
Feeds spray guns in a refinish booth; the 5 um element trims finer particulate than the standard element before air reaches the gun and the finish.
Rotary filling machine pilot air
Supplies pilot air to the fill-head valves on a rotary filler, where a steady regulated pressure keeps dosing and valve timing consistent.
Laboratory automation skid
Regulates air to the small actuators on a laboratory automation skid; the automatic drain keeps condensate away from the instruments.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010AJNW) the Right Unit?
Choose this 300 size (PT3/8) when the served line draws more air than a 200-size port comfortably handles. Automatic drain suits unattended or hard-to-reach installations; manual or differential-pressure drain are the alternatives. Pick the W-coded 5 um element over the standard 40 um when downstream equipment - spray guns, pilot valves, sensitive actuators - tolerates less particulate.
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering. The thread is standard PT; G (BSPP) and NPT are order options, and the J code means no mounting bracket is supplied.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 Filter Regulator (GFR30010AJNW) FAQ
AirTAC publishes flow for this series as curves rather than one rated figure, so we do not state a single number. Tell us your working pressure and downstream demand and we will confirm the correct size from the datasheet on request.
The W code here means the 5 um element, which filters finer than the standard 40 um grade. Use it for spray equipment, pilot valves and other sensitive downstream gear; the 40 um grade is the economical choice for general plant air. We can confirm suitability for your application on request.
