AirTAC GFR300-10 Filter Regulator (GFR30010JF1K)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010JF1K) 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 PT3/8" 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 GFR300-10 Filter Regulator (GFR30010JF1K)
GFR30010JF1K is a genuine AirTAC GFR300 filter regulator: filtration and pressure regulation combined in one body, with a PT3/8 (3/8 in.) port. This configuration carries the standard 40 um filter element, a differential-pressure drain, an embedded square pressure gauge scaled in MPa, and a reverse (check) valve fitted at the outlet. Outlet pressure is set anywhere within 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the bowl on size 300 is polycarbonate (PC).
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200 to 600 with ports from 1/8 to 1 inch, in PT as the standard thread and G (BSPP) or NPT as catalogue options. Filter grade, drain type, gauge style and scale, bracket and reverse-valve choices are all listed options. AirTAC publishes flow as curves rather than a single rated figure, so we confirm the datasheet numbers for your operating point 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. |
|---|---|
| 10 | Port size PT3/8". 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. |
| 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. |

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 (GFR30010JF1K) Is Used
Bottling line clamp cylinders
Feeds filtered, pressure-stabilised air to the clamping and capping cylinders on a filling line, with the check valve holding the regulated setting at the actuator side.
Plasma cutting air supply
Conditions the shop-air feed to a plasma cutter bench, removing water and particulate before the torch line and keeping torch inlet pressure steady during cutting.
Pneumatic press clamping circuit
Sits ahead of the clamping circuit on a small pneumatic press, supplying clean air and a fixed clamp pressure read off the embedded MPa gauge.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010JF1K) the Right Unit?
GFR300 covers mid-size circuits; if your port or demand is larger, step to GFR400 or GFR600 (ports up to 1 inch), or down to GFR200 for 1/8 and 1/4 in. lines. This code specifies a 40 um element - choose W for 5 um where finer filtration is needed - and a differential-pressure drain; automatic (A) and manual (M) drains are catalogue options. The J in the code means no bracket; a mounting bracket is optional. Thread is PT as standard, with G (BSPP) and NPT orderable; gauge scale can be MPa, psi or bar on the embedded square gauge, with an external round gauge also available.
Because AirTAC publishes flow only as curves and not as a single rated number, ask us to confirm sizing against the datasheet for your inlet pressure and downstream demand before ordering.
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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR300-10 Filter Regulator (GFR30010JF1K) FAQ
AirTAC publishes flow for the GFR series as characteristic curves rather than a single rated figure, so there is no one rated flow number to quote. Tell us your inlet pressure, outlet setpoint and downstream demand and we will confirm the datasheet figure for that operating point before you order.
K decodes as a reverse (check) valve fitted at the outlet, so downstream air is held if the upstream supply drops. The same GFR300 unit is also available without the check valve, with a 5 um element (code W), manual or automatic drain, and G or NPT thread in place of PT.
