Airtac GFR Filter Regulator GFR400C10AN
The AirTAC GFR Filter Regulator GFR400C10AN 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 GFR400C10AN
The AirTAC GFR series is a filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure in a single body. This 400-size unit is supplied with 3/8 in. PT ports, a polycarbonate bowl with automatic drain, the standard 40 um filter element, and no pressure gauge fitted. With the automatic drain, the outlet pressure is adjustable over 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C.
This is a genuine AirTAC part. G series filter regulators come in 200, 300, 400 and 600 sizes with ports from 1/8 in. to 1 in., a choice of differential-pressure, automatic or manual drain, an optional 5 um element, gauge options, and G (BSPP) or NPT threads to order. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 GFR400C10AN Is Used
Pneumatic stamping press feed
Filtered, regulated air to the 3/8 in. inlet of a bench or floor-standing pneumatic press, with the automatic drain clearing bowl condensate between shifts.
Cartoning line cylinder supply
A point-of-use filter regulator feeding the pick-and-place and sealing cylinders on a packaging conveyor line.
Machine shop air drop
Regulated air at an individual workshop drop, protecting air tools and small actuators from pressure swings and water carryover.
Is the Airtac GFR Filter Regulator GFR400C10AN the Right Unit?
Size 400 with 3/8 in. PT ports sits mid-range in the G series; step down to 300 or up to 600 if your circuit's flow sits elsewhere - we can check the published flow curves against your demand before you order. This version has the automatic drain, which discharges condensate without attention; manual and differential-pressure drains are available on the same body. The standard element is 40 um; the W suffix gives 5 um. The unit is supplied without a gauge - an embedded square gauge or an external round gauge with MPa, psi or bar scales can be ordered. PT thread is standard and G (BSPP) or NPT are order options; a mounting bracket is included and can be deleted with the J suffix.
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 GFR400C10AN FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the sizing against the datasheet curves before you order.
The A suffix fits an automatic drain that discharges collected condensate without anyone opening the bowl, which suits lines running unattended. Manual-drain versions are emptied by hand and have a 0.05-0.9 MPa (7-130 psi) setting range, while automatic and differential-pressure drain versions set 0.15-0.9 MPa (20-130 psi). All three are available on this 3/8 in., 40 um filter regulator.
