AirTAC GFR300-10 Filter Regulator (GFR30010AJF1W)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010AJF1W) 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 (GFR30010AJF1W)
The GFR30010AJF1W is an AirTAC GFR-series filter regulator: filtration and pressure regulation in a single body. This 300-size unit has a 3/8in PT port, a 5 um filter element for finer particulate and water removal than the standard 40 um grade, an automatic drain that clears condensate from the polycarbonate bowl on its own, and an embedded square gauge reading in MPa. The regulator setting range with this automatic-drain version is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the temperature range is -5 to 70 C, non-freezing. The J suffix means no mounting bracket is fitted.
This is a genuine AirTAC part. The G-series filter regulator range runs from 200 to 600 size with ports from 1/8in to 1in, and drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as catalogue options) and bracket are all specifiable. Rated flow is published as curves rather than a single figure, so contact us and we will confirm flow and full datasheet figures for your application.

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 (GFR30010AJF1W)
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |

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 GFR300-10 Filter Regulator (GFR30010AJF1W) Is Used
Paint spray booth air prep
Feed spray guns in a paint booth through this 5 um filter regulator so finer particulate is stripped from the atomizing air before it reaches the finish, with the auto drain handling compressor moisture.
Electronics assembly pick-and-place
Supply the vacuum ejectors and gripper cylinders of a PCB pick-and-place machine, where the 5 um element protects fine components from airborne debris and the MPa gauge matches the machine's metric controls.
Pneumatic torque tool station
Set up a maintenance bench of pneumatic nutrunners and impact tools on this 3/8in unit, giving the tools filtered, regulated air at a repeatable preset while condensate drains automatically between shifts.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010AJF1W) the Right Unit?
Size 300 is the 3/8in port step of the G-series; select 200 for 1/4in circuits or 400/600 for 1/2in and larger mains, since an undersized unit costs you pressure drop at flow. This code pairs the 5 um element with automatic drain and a square MPa gauge, a sensible combination for sensitive downstream equipment; the 40 um element suits general plant air, and round gauges in bar or psi, or no gauge, are the other gauge choices. PT thread is standard; order G (BSPP) or NPT to match your pipework, and add a bracket if panel mounting is needed.
Flow is published as curves, not a single rated number, so send us your application conditions and we will confirm sizing against the datasheet before you order.
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 (GFR30010AJF1W) FAQ
AirTAC publishes flow for this series as characteristic curves rather than a single rated figure, so we will not quote an unverifiable l/min or SCFM number. Tell us your inlet pressure, set pressure and demand, and we will confirm the flow data from the datasheet for this exact 3/8in configuration before you order.
The W suffix changes the filter element from the standard 40 um grade to 5 um, which captures finer particulate and suits sensitive equipment such as spray guns, instrumentation and small cylinders. Everything else in this code stays the same: 3/8in PT port, automatic drain, square MPa gauge and the 0.15-0.9 MPa (20-130 psi) setting range. If your application is general plant air, the non-W GFR30010AJF1 is the standard choice.
