AirTAC GFR300-10 Filter Regulator (GFR30010JF1W)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010JF1W) 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 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 (GFR30010JF1W)
GFR30010JF1W is a genuine AirTAC GFR300 filter regulator: filtration and pressure regulation in a single body with a PT3/8 (3/8 in.) port. The W in the code selects the fine 5 um filter element instead of the standard 40 um, together with a differential-pressure drain and an embedded square pressure gauge scaled in MPa. Set the outlet anywhere in 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi), and the size 300 bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series line, which runs from size 200 to 600 with ports from 1/8 to 1 inch, PT as the standard thread and G (BSPP) or NPT as orderable options. Drain type, filter grade, gauge scale, bracket and check-valve choices are all catalogue options. AirTAC publishes flow as curves rather than a single rated figure, so we confirm the datasheet numbers for your condition on request.

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 (GFR30010JF1W) Is Used
Paint spray booth gun feed
Supplies finely filtered, regulated air to spray guns in a booth line, where the 5 um element helps keep contaminants out of the finish and the gauge anchors the gun supply pressure.
Packaging machine diverters
Feeds the diverter and pusher cylinders on a carton packaging machine with filtered air held at a steady setpoint so stroke timing stays repeatable across the shift.
Lab autoclave and test-rig air
Conditions instrument air on a laboratory test rig, removing water and fine particulate ahead of pneumatic controls that tolerate little contamination.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010JF1W) the Right Unit?
GFR300 suits mid-size circuits; move to GFR200/GFR400 (or GFR600 for ports up to 1 inch) if the port or demand differs. The key choice in this code is the 5 um element (W) versus the 40 um standard - finer filtration protects sensitive valves and instruments but loads faster in dirty air. Drain here is the differential-pressure default; automatic (A) and manual (M) drains are options. The J means no bracket (a bracket is optional), thread is PT as standard with G and NPT orderable, and the embedded square gauge can be scaled in MPa, psi or bar, with an external round gauge available.
Flow is published only as curves, not a single rating, so send us your line pressure and air demand and we will confirm sizing from 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 (GFR30010JF1W) FAQ
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Share your inlet pressure, outlet setpoint and demand, and we will confirm the datasheet flow for that operating point on request.
The W decodes as a 5 um filter element, one step finer than the 40 um standard, for applications such as coating, instrumentation or testing that need cleaner air. It is fitted in the same GFR300 body with the same PT3/8 port, differential-pressure drain and MPa gauge; a 40 um version and manual or automatic drains are orderable alternatives.
