AirTAC GFR400-15 Filter Regulator (GFR40015JC1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015JC1W) 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 PT1/2" 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 GFR400-15 Filter Regulator (GFR40015JC1W)
The GFR400-15JC1W is an AirTAC G-series filter regulator in the 400 size with a 1/2 in port and PT thread. It filters water and particulate down to 5 um - the finer W grade - and regulates downstream pressure over 0.15-0.9 MPa (20-130 psi), the range that applies with the differential-pressure drain in this code. This configuration includes an external round pressure gauge scaled in MPa.
This is a genuine AirTAC part. The GFR series spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as catalogue options, plus manual, automatic or differential-pressure drains, 40 um or 5 um filter grades, gauge choices and low-pressure (L) variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet for your application.

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 GFR400-15 Filter Regulator (GFR40015JC1W) Is Used
Pneumatic valve island protection
Finely filtered, regulated air upstream of the valve island and rodless cylinders on an automated assembly line, keeping 5 um-grade air at the set pressure the valves were sized for.
Lab automation actuator supply
Clean 5 um air feeding grippers and lift stages on laboratory automation equipment, where the MPa gauge lets technicians verify set pressure against the equipment specification.
Conveyor divertor air feed
Regulated supply to the diverter and stopper cylinders along a parcel-sort conveyor, with the differential-pressure drain managing bowl drainage across continuous multi-shift running.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015JC1W) the Right Unit?
The 400 size gives a 1/2 in port against 3/8 in on the 300, so match the port to your main line and confirm sizing against the published flow curves before ordering. The W code selects the 5 um element instead of the standard 40 um - choose it when downstream valves and cylinders need finer protection. The differential-pressure drain clears the bowl automatically; manual (M) or automatic (A) drain codes exist if your duty suits them better. The round gauge here reads in MPa; psi (2) and bar (3) scales are orderable. PT is the standard thread - order G or T suffixes for BSPP or NPT, and add a bracket version if you will mount the unit.
Since flow is published as curves and not a single rated number, 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 (PT1/2" 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 GFR400-15 Filter Regulator (GFR40015JC1W) FAQ
AirTAC publishes flow for this series as curves rather than a single rated figure, so no flow number is stated here. Share your working pressure and air consumption and we will confirm the datasheet curve and whether the 1/2 in port suits your application before you order.
Choose W when downstream components - precision valves, air bearings, pneumatic instrumentation - need finer particulate protection than the standard 40 um element provides. The 40 um version of this unit is GFR400-15JC1 without the W; both fit the same 1/2 in PT port.
