Airtac GFR Filter Regulator GFR400C10F1WK
The AirTAC GFR Filter Regulator GFR400C10F1WK 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 GFR400C10F1WK
The AirTAC GFR400 series is a filter regulator: filtration and pressure regulation in one body, with a drain bowl and no lubricator. This GFR400C10F1WK is the 400 size on a PT3/8 port (standard PT thread), combining the 5 um element (W instead of the standard 40 um), a fitted reverse (check) valve (K) that holds the downstream setting if the upstream supply drops, the differential-pressure drain, and the embedded square gauge on a MPa scale plus the round external gauge (C). Maximum working pressure is 1.0 MPa (145 psi), the regulation span is 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain, and the polycarbonate (PC) bowl unit runs on compressed air from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 frames with ports from 1/8 to 1 in, and options include the standard 40 um grade, no-check-valve versions, automatic or manual drains, other gauge scales, no-gauge (N) and no-bracket (J) variants, and G (BSPP) or NPT threads instead of PT. Flow is published as performance curves rather than a single rated figure, so we confirm datasheet and flow values on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

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 GFR400C10F1WK Is Used
Spray-booth gun feed
Cleaning and regulating the air feed to spray guns in a paint booth, with the reverse valve holding the gun-line setting through brief compressor unload cycles.
Flow-wrapper seal jaws
Supplying seal-jaw cylinders on a horizontal flow-wrapper, where the 5 um element suits the machine valve train and the check valve keeps jaw pressure in place at cycle stop.
Process valve actuation
Regulating air to pneumatic actuators on process valves in a water treatment plant, keeping the actuator feed both clean and held against supply dips.
Is the Airtac GFR Filter Regulator GFR400C10F1WK the Right Unit?
Step between the 200/300/400/600 frames as your port and flow demand changes; this 400 unit connects on 3/8 in PT. Here W selects the 5 um element over the standard 40 um, and K adds the reverse/check valve - drop either code if you want the plainer configuration. With the coded differential-pressure drain the regulation span is 0.15-0.9 MPa (20-130 psi); manual-drain versions quote 0.05-0.9 MPa (7-130 psi) and an automatic drain is available. Gauge scales come in MPa, psi or bar. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and the bracket is included (J deletes it). 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 GFR400C10F1WK FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a rating here. Give us your flow and pressure conditions and we will confirm the datasheet curve values and correct frame size on request before you order.
W fits the 5 um element in place of the standard 40 um, and K fits a reverse (check) valve so the downstream setting is held if the supply side drops. The differential-pressure drain, MPa square gauge plus round external gauge, and the PT3/8 port are as on the base unit.
