AirTAC GFR400-15 Filter Regulator (GFR40015AF1W)
The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015AF1W) 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 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 GFR400-15 Filter Regulator (GFR40015AF1W)
The AirTAC GFR40015AF1W is a GFR-series filter regulator specified with the W fine-filtration element: 5 um filtration instead of the 40 um standard, for air lines feeding more sensitive components. It combines water and particulate removal with pressure regulation in one body, size 400 with PT1/2 ports, automatic drain, and the embedded square gauge with MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi); setting range with automatic drain is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200 to 600 with PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, an optional check valve, and bracket options. Because flow is published as curves rather than a single rating, we confirm the datasheet figures for your application on request.

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 (GFR40015AF1W) Is Used
Laboratory analytical instruments
Supplying sample-handling pneumatics on laboratory analysers, the 5 um element gives finer particulate removal than the standard grade while the regulator holds a stable instrument supply pressure.
Air bearing and guidance rails
On precision handling equipment using air guides, the unit removes water and fine particulate from the supply and regulates the pressure feeding the air bearings.
Paint spraying booths
At a spray booth drop, the fine 5 um element reduces particulate carryover into the finishing air while the regulator sets a consistent atomisation pressure.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015AF1W) the Right Unit?
Specify the W element when downstream equipment needs finer filtration than the standard 40 um grade. Size 400 with 1/2 inch ports suits higher-demand circuits; move to 600 if the flow curves require it. Automatic drain suits unattended operation (0.15-0.9 MPa setting range), while manual drain extends the range to 0.05-0.9 MPa. Thread is PT as standard with G and NPT as orderable options, and a bracket is included. The embedded square gauge reads in MPa.
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 (GFR40015AF1W) FAQ
AirTAC publishes flow for the G series as characteristic curves, not a single rated figure, so no flow number is quoted here. Request the datasheet from us and we will confirm the sizing against the curves for your application before you order.
W specifies the optional 5 um filter grade for lines feeding more contamination-sensitive equipment; the standard element is 40 um. Everything else in the code is unchanged: PT1/2 ports, automatic drain, square MPa gauge, 1.0 MPa maximum inlet and a 0.15-0.9 MPa setting range.
