Airtac GFR Filter Regulator GFR300C10JF1
The AirTAC Airtac GFR Filter Regulator GFR300C10JF1 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 GFR300C10JF1
The GFR300C10JF1 is an AirTAC G-series filter regulator: water and particulate filtration plus pressure regulation combined in one body, with no lubricator. This configuration is the 300 size with 3/8 in PT ports, a 40 um standard element, a differential-pressure drain, and the embedded square gauge scaled in MPa (F1). The J suffix means it is ordered without a mounting bracket. Regulator adjustment range is 0.15-0.9 MPa (20-130 psi) with this drain type, maximum inlet pressure is 1.0 MPa (145 psi), and operating temperature is -5 to 70 C, non-freezing. The bowl on the 300 size is polycarbonate (PC).
This is a genuine AirTAC part for the US market. The GFR300 frame is one step in the G platform, which runs from 200 through 600 sizes with ports from 1/8 to 1 in, G(BSPP) and NPT thread options, a 5 um (W) element option, automatic or manual drain variants, and a check valve option. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow figures on request before you order.

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 GFR300C10JF1 Is Used
Packaging machine air prep
Conditions and regulates plant air feeding the directional valves and cylinders of a carton-sealing or case-packing line, draining condensed water before it reaches the valve stack.
Pneumatic clamp circuits
Sets and holds a steady working pressure for clamp cylinders on a welding or assembly fixture, so clamping force stays consistent across the shift.
Conveyor divert and pusher stations
Regulates supply air to cylinder-driven pushers and diverters on a sorting conveyor, with the differential drain bleeding accumulated water during normal flow.
Is the Airtac GFR Filter Regulator GFR300C10JF1 the Right Unit?
Start with the port step: this 300 unit carries 3/8 in PT threads - step up to the 400 or 600 frame for larger circuits or down to 200 for compact ones. Drain is differential-pressure as standard here; automatic (A) and manual (M) drains are available on the same frame, and manual-drain versions widen the adjustment range to 0.05-0.9 MPa (7-130 psi). The 40 um element suits general plant air; add the W suffix for 5 um. This code includes the embedded square MPa gauge; an external round gauge is an optional extra, and a bracket can be added by dropping the J suffix. Thread is PT as standard, with G and NPT as catalogue options. G-series flow is published as curves, not a single rating, so ask us to confirm sizing against your 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 GFR300C10JF1 FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your required flow and working pressure and we will confirm the datasheet curve and the right frame size for your application before you order.
Yes. The JF1 code carries the differential-pressure drain, which works off flow to expel condensate. Automatic (A) and manual (M) drains are catalogue options on the same 300 frame; note that choosing a manual drain changes the regulator adjustment range to 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for this version.
