Airtac GFR Filter Regulator GFR400C15MC1W
The AirTAC GFR Filter Regulator GFR400C15MC1W 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 GFR400C15MC1W
GFR400C15MC1W is an AirTAC GFR-series filter regulator specified with the 5 um element (code W), the finer of the two filtration grades offered in the series. It removes water and particulate from compressed air and regulates downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) span that applies to the manual-drain version. Condensate collects in the polycarbonate bowl and is released by opening the manual drain. The port is PT1/2, the standard thread for this series, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). An external round pressure gauge with MPa scale (code C1) is fitted and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 in, and offers differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge styles and scales, G or NPT threads and a check-valve variant (code K). Flow is published as curves rather than a single rating, so we confirm sizing and supply the datasheet 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 GFR400C15MC1W Is Used
Paint spray line supply
Filtered, regulated air feeding spray guns in a finishing booth, where the 5 um element helps keep finish-ruining particulate out of the air stream.
Test rig instrument air
Clean, steady pressure for the transducers, cylinders and pilot valves on a laboratory or production test rig, with the MPa gauge giving a clear set-point readout.
Diaphragm pump air feed
Regulated air to an air-operated double-diaphragm pump on a chemical transfer duty, with the manual drain bled during scheduled plant rounds.
Is the Airtac GFR Filter Regulator GFR400C15MC1W the Right Unit?
Pick the W code when the circuit needs finer than the standard 40 um filtration, for example to protect precision components or small-bore piping, while keeping the size 400, 1/2 in PT body. The manual drain suits attended installations where the bowl is bled on a routine; automatic (A) and differential-pressure drain versions are available for hands-off operation. The round gauge reads in MPa, with psi and bar scales, embedded square gauges and no-gauge codes among the catalogue options, alongside G or NPT threads and the K check valve. We will confirm the size step against the published flow curve for your demand before you order.
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 GFR400C15MC1W FAQ
AirTAC does not publish a single rated flow figure for the GFR series; flow is given as curves. That is why no number appears here. Share your inlet pressure, set pressure and air demand with us and we will confirm the fit from the datasheet on request.
PT is the standard thread for this series, and that is what the base code GFR400C15MC1W carries. G (BSPP) and NPT versions are catalogue options ordered by adding the corresponding letter code to the model, so match the thread to your piping standard rather than adapting fittings.
