Airtac GFR Filter Regulator GFR400C10AF1W
The AirTAC GFR Filter Regulator GFR400C10AF1W 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 GFR400C10AF1W
GFR400C10AF1W is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This code decodes as the 400 size with a 3/8 in PT port, automatic drain, the embedded square pressure gauge graduated in MPa and, per the W suffix, the finer 5 um filter element in place of the standard 40 um; the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), operating range is -5 to 70 C (non-freezing), the 400-size bowl is polycarbonate, and with automatic drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The same filter regulator is offered from size 200 to 600 with ports from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, the 40 um standard element, G or NPT threads, psi or bar gauge scales and a reverse (check) valve under their own codes. Flow is published as curves rather than a single rating, so we confirm datasheet 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 GFR400C10AF1W Is Used
Fine finishing spray booth
Provides 5 um filtered, regulated air to spray guns in a furniture finishing booth, where finer particle removal upstream of the gun supports a cleaner finish.
Laboratory test rig
Conditions the compressed-air supply to a laboratory test rig, giving instruments and pneumatic controls air cleaned to 5 um and held at the pressure set on the MPa gauge.
Control valve positioners
Feeds filtered air to pneumatic valve positioners on a process skid, with the regulator set from the MPa gauge to the supply the positioner requires.
Is the Airtac GFR Filter Regulator GFR400C10AF1W the Right Unit?
The key choice on this code is filter grade: the W suffix specifies the 5 um element, against the 40 um standard fitted to the base GFR400C10AF1. Use 5 um where the downstream equipment needs finer air, and 40 um for general cylinder and valve protection; both fit the same 400 body with 3/8 in PT port. Drain is automatic here, with manual (M) and differential-pressure (blank) variants under their own codes; the adjust range is 0.15-0.9 MPa (20-130 psi) on auto and differential drains and 0.05-0.9 MPa (7-130 psi) on manual. Gauge scale is MPa as coded, with psi or bar orderable, and PT is the standard thread with G and NPT options.
AirTAC publishes flow for this family as curves, not a single rated figure, so ask us to confirm the datasheet and 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 GFR400C10AF1W FAQ
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not state a flow number. Tell us your flow and working pressure and we will confirm the datasheet curve for this 400 size, 3/8 in port unit on request.
The W in the code specifies the 5 um element for applications that need finer cleaning, such as spray finishing or instrument air, while the 40 um element on the base code suits general cylinder and valve supply. Both are catalogue grades for the same body, and we can confirm element details on request.
