Airtac GFR Filter Regulator GFR400C10AJF1
The AirTAC GFR Filter Regulator GFR400C10AJF1 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 GFR400C10AJF1
The GFR400C10AJF1 is an AirTAC G-series filter regulator: one body strips water and particulate from compressed air and holds downstream pressure at your set point. This size 400 configuration takes a 3/8 in PT port, uses the standard 40 um element, drains condensate automatically (code A) and carries the embedded square gauge with an MPa scale (code F1). The bowl is polycarbonate.
It is a genuine AirTAC part. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this automatic drain, and the working temperature range is -5 to 70 C (non-freezing). AirTAC publishes flow for the G series as curves rather than a single rating, so we confirm datasheet and sizing figures 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 GFR400C10AJF1 Is Used
Packaging line cylinder supply
Feeds the forming and sealing cylinders on a carton packaging machine, removing compressed-air water and holding one steady pressure setting for repeatable strokes.
Fixture clamping circuit
Sits upstream of the clamp cylinders on a pneumatic fixture in a machining cell; the automatic drain clears condensate between cycles without operator attention.
Bottling line blow-off
Supplies filtered, regulated air to the nozzle that dries bottles before labelling on a bottling line.
Is the Airtac GFR Filter Regulator GFR400C10AJF1 the Right Unit?
Step between sizes 200, 300, 400 and 600 to match the port and air demand; this size 400 unit uses a 3/8 in PT port and can be ordered with G (BSPP) or NPT thread instead. Drain choices are differential-pressure (the default), automatic as here, or manual, and the element is 40 um standard or 5 um with the W suffix. A mounting bracket can be included or omitted (code J omits it on this model). AirTAC publishes G-series flow as curves, not a single rated figure, so ask us to confirm sizing against your flow demand 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 GFR400C10AJF1 FAQ
AirTAC publishes G-series flow as curves, not as a single rated number, so we do not quote one figure here. Send us your required downstream flow and working pressure and we will confirm the correct size from the datasheet on request.
The A code specifies automatic condensate discharge from the bowl, so no operator attention is needed. G-series filter regulators can alternatively be ordered with a manual drain or with the differential-pressure drain that is the default. Note that the regulation range also depends on drain type: 0.15-0.9 MPa (20-130 psi) with automatic drain, 0.05-0.9 MPa (7-130 psi) with manual.
