Airtac GFR Filter Regulator GFR400C15AC1W
The AirTAC GFR Filter Regulator GFR400C15AC1W 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 GFR400C15AC1W
GFR is AirTAC's filter regulator family: filtration and pressure regulation combined in one body, with a drain bowl and no lubricator. This GFR400C15AC1W is the 400 size with a 1/2 in PT port (PT is the standard thread; G and NPT are catalogue options), an automatic drain, an external round pressure gauge scaled in MPa, and the W code specifying the 5 um filter element instead of the 40 um standard grade. With the automatic drain, the setting range is 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part, rated -5 to 70 C (non-freezing), with the 400 size bowl in polycarbonate (PC). The G-series runs from size 200 to 600, with automatic, manual or differential-pressure drains, 40 um standard or 5 um (W) elements, embedded square or external round gauges, and an optional reverse/check valve (K). Flow is published 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.

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 GFR400C15AC1W Is Used
Atomizing air to a paint spray booth
Prepares the atomizing air feed to spray guns in a paint booth, with the 5 um element giving finer prefiltration than the standard 40 um grade.
Pneumatic test rig in a quality lab
Feeds bench-top pneumatic test rigs in a quality laboratory, where the 5 um element keeps coarse particles out of gauges and test couplings.
Air knife on an electronics conveyor
Supplies the air knives that dry circuit boards along an electronics handling conveyor, with the automatic drain clearing condensate from the main line.
Is the Airtac GFR Filter Regulator GFR400C15AC1W the Right Unit?
Pick the 400 size with its 1/2 in port when your circuit steps up from the 300 (3/8 in) frame, or move to the 600 (3/4 in and 1 in) frames for larger demand. This version carries the W code for the 5 um element - choose it where finer prefiltration is wanted; the 40 um standard grade is available on the same frame. The drain is automatic, with manual and differential-pressure drains as alternatives. The gauge is the external round type in MPa; square gauges and psi or bar scales are options. PT is the standard thread, with G (BSPP) and NPT orderable as catalogue options, and a mounting bracket is included as standard (J variants omit it). Because flow is published as curves rather than 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 GFR400C15AC1W FAQ
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not state a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The standard grade is 40 um, which suits general cylinder and valve supply. The W in this code specifies the 5 um element for finer prefiltration, for example ahead of sensitive instruments or nozzles. Both grades are catalogue options on the same 400 frame.
