AirTAC GFR400-10 Filter Regulator (GFR40010F1WK)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010F1WK) 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 GFR400-10 Filter Regulator (GFR40010F1WK)
GFR40010F1WK is an AirTAC GFR filter regulator: a 400-size unit that cleans the compressed air and holds downstream pressure in a single body. The 10 port is PT3/8, filtration is the fine 5 um element (W code), drainage is the differential-pressure bowl (the default), the gauge is the embedded square type on an MPa scale, and a reverse (check) valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi); with this drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing, and the 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, with 5 um or 40 um filtration, automatic, manual or differential-pressure drains, G (BSPP) and NPT thread options, and round or square gauges where a regulator is fitted. Flow is published as characteristic curves rather than a single rating, so ask us and we will confirm the datasheet figures 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 GFR400-10 Filter Regulator (GFR40010F1WK) Is Used
Bottling line fill-valve actuators
Feeds the pneumatic fill and capping valves on a bottling line: the 5 um element keeps moisture and fine debris out of the valve spools while the regulator holds a steady working pressure for consistent fill-sequence actuation.
CNC fixture clamping circuits
Serves the air-powered clamps on a machining-centre fixture table. The check valve helps hold the set downstream pressure if supply pressure dips, and the fine 5 um grade protects the clamp cylinders between filter services.
Paint-shop spray booth air drops
Installed at the booth drop for air-assisted spray equipment, where the 5 um filtration and regulated, gauge-monitored pressure give painters a repeatable setup at each station.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010F1WK) the Right Unit?
Step up or down through the G series - 200, 300, 400, 600 - to match port size and flow demand; this 400 size with its PT3/8 port is the mid-large step. Choose the drain: differential-pressure (as here), fully automatic, or manual. Pick 5 um (this model, W) or the standard 40 um element, set the gauge to square (embedded) or round with MPa, psi or bar scale, and order G or NPT threads instead of the PT standard if your piping needs them.
Before ordering, note that published flow data for this family is in the form of curves, not one rated number. Send us your application details and we will confirm sizing from the datasheet first.
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 GFR400-10 Filter Regulator (GFR40010F1WK) FAQ
AirTAC publishes G-series flow as characteristic curves rather than one rated number, so we do not quote a l/min or SCFM figure here. Tell us your application and we will confirm the datasheet flow data for this 400-size, 3/8 in unit before you order.
The K code fits a reverse (check) valve so downstream pressure is retained if the supply drops. This unit uses the default differential-pressure drain, which gives a 0.15-0.9 MPa (20-130 psi) regulation span; if you prefer a manual drain, the span widens to 0.05-0.9 MPa (7-130 psi) on the corresponding variant.
