AirTAC GFR400-15 Filter Regulator (GFR40015MC4W)
The AirTAC GFR400-15 Filter Regulator (GFR40015MC4W) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MC4W)
The AirTAC GFR400 series delivers filtration and pressure regulation in a single body: water and particulate are removed from the compressed air, which is then held at your set working pressure. This 400-size unit has a 1/2 inch PT port, a 5 um fine filter element, a manual drain bowl, and an external round gauge in the scale-4 option (we confirm the exact gauge scale on request). With manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and service is -5 to 70 C with the polycarbonate bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, G (BSPP) and NPT thread options, automatic or differential-pressure drain choices, 40 um standard or 5 um elements, gauge and scale variants, and optional brackets. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow 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 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MC4W) Is Used
Process valve actuation skid
Conditions and regulates the air supply to pneumatic ball and butterfly valve actuators on a process skid: clean 5 um air protects actuator seals, and a fixed set pressure gives consistent valve stroking.
Food plant washing and diverting gates
Feeds diverter gates and reject cylinders on a food processing line: filtered, regulated air keeps gate motion consistent through the shift, with manual drain performed during scheduled washdown checks.
Textile machine jet and cylinder air
Supplies pneumatically actuated guides and tension arms on textile machinery, where fine 5 um filtration helps keep sensitive pneumatic components clean and the regulator holds a steady working pressure.
Is the AirTAC GFR400-15 Filter Regulator (GFR40015MC4W) the Right Unit?
GFR400 with a 1/2 inch PT port sits in the mid-large band of the range; step to 300 or 600 depending on the flow your system needs - and because flow is published as curves, not one rating, ask us to confirm sizing against your application before ordering. The W code selects the 5 um element for finer air quality; 40 um is standard. Manual drain gives the wider 0.05-0.9 MPa (7-130 psi) regulation range and requires routine bowl draining; automatic or differential-pressure drain versions avoid that. This unit carries an external round gauge in the scale-4 option - if you need MPa, psi or bar specifically, those scales are available and we confirm the exact scale for this code on request. Thread is PT as standard, with G (BSPP) and NPT as catalogue options; a J code orders the unit without a bracket.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 0.05 - 0.9 MPa (7 - 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 GFR400-15 Filter Regulator (GFR40015MC4W) FAQ
No single rated flow is quoted, because AirTAC publishes flow for this series as curves rather than one number. Share your working pressure and air consumption and we will confirm the correct sizing from the datasheet on request.
The gauge code here is C4: C is the external round gauge and 4 is the scale option for that code. MPa (1), psi (2) and bar (3) scales are catalogue alternatives, so if you need a specific scale, tell us and we will confirm the exact gauge fitted before you order.
