Airtac GFR Filter Regulator GFR400C10F1
The AirTAC GFR Filter Regulator GFR400C10F1 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 GFR400C10F1
The AirTAC GFR400 series is a filter regulator: filtration and pressure regulation built into one body, with a drain bowl and no lubricator. This GFR400C10F1 is the 400 size on a PT3/8 port (standard PT thread), configured with the differential-pressure drain, a 40 um element and the embedded square gauge on a MPa scale; the C in the code also specifies the round external gauge. 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 within this family you can order automatic or manual drains, a 5 um element (W), a reverse/check valve (K), other gauge scales, no-gauge (N) and no-bracket (J) versions, and G (BSPP) or NPT threads instead of PT. AirTAC publishes flow 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 GFR400C10F1 Is Used
Case-packer gripper supply
Filtering and regulating the 3/8 in air drop that feeds gripper and clamp cylinders on a case-packing machine, so carton-pick actuators work from clean, steady pressure.
Rotary bottling filler
Conditioning the compressed-air branch that drives filler valves and stopper presses on a rotary bottling line, with the MPa gauge giving operators a clear setpoint to work to.
Fixture clamping circuit
Regulating the supply to pneumatic clamps on a machining fixture, setting a repeatable clamp pressure at the fixture rather than back at the compressor.
Is the Airtac GFR Filter Regulator GFR400C10F1 the Right Unit?
Size and port step up together: the 200/300/400/600 frames carry progressively larger ports and flow, and this 400 unit takes a 3/8 in PT connection. The drain choice is real: the coded differential-pressure drain quotes a 0.15-0.9 MPa (20-130 psi) regulation span, while manual-drain versions widen it to 0.05-0.9 MPa (7-130 psi), and an automatic drain is also a catalogue option. Element grade is 40 um as coded or 5 um with W, and 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). Because flow is published as curves, not a single rating, 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 GFR400C10F1 FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your flow and pressure conditions and we will confirm the datasheet figures and the correct size on request before you order.
It is the coded drain: the bowl vents collected condensate according to the pressure differential, with no operator action needed. Automatic and manual drains are catalogue alternatives - note the regulation span is 0.15-0.9 MPa (20-130 psi) with this drain, while manual-drain versions are quoted from 0.05 MPa.
