Airtac GFR Filter Regulator GFR400C15MF1W
The AirTAC GFR Filter Regulator GFR400C15MF1W 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 GFR400C15MF1W
GFR400C15MF1W is a genuine AirTAC G-series filter regulator: a 400-size unit that cleans compressed air and regulates downstream pressure in one body. This configuration pairs a 1/2 in PT port with a manual-drain polycarbonate bowl, the fine 5 um filter element, and the embedded square pressure gauge scaled in MPa. The 5 um element suits circuits with sensitive valves and cylinders; manual drain means an operator opens the bowl drain to clear collected water on a routine round.
Max inlet pressure is 1.0 MPa (145 psi); with a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi), and working temperature is -5 to 70 C. The G-series spans 200, 300, 400 and 600 sizes from 1/8 in to 1 in ports, with automatic, manual or differential-pressure draining, 40 um or 5 um elements, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and bracket or no-bracket mounting. 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 GFR400C15MF1W Is Used
Electronics assembly pick-and-place
Supplying the pick-and-place heads on an electronics assembly module, where the 5 um element protects venturi vacuum generators and small pilot valves from particles and the regulator holds the pressure their nozzles were set up with.
High-speed cartoner air supply
Conditioning the air feeding the high-speed cylinders and actuators of a cartoning machine, where fine 5 um filtration and a stable regulated pressure keep short-stroke motions repeating cleanly at line speed.
Laboratory pneumatic rig
Feeding a laboratory rig that exercises pneumatic samples and prototypes, where the 5 um grade keeps test air clean, the MPa-scaled square gauge documents the set pressure, and the manual drain is emptied between test runs.
Is the Airtac GFR Filter Regulator GFR400C15MF1W the Right Unit?
The 400 size with 1/2 in ports sits in the upper-mid band of the G-series; step down to 300 (3/8 in) or up to 600 (3/4 in - 1 in) to match the flow your line draws. Drain: manual suits units visited on a routine inspection round; choose automatic (A) or the differential-pressure default where the bowl is awkward to reach. Element: the W in this code selects the 5 um grade for finer protection of downstream valves and cylinders; the standard 40 um grade covers general line supply. Gauge: the embedded square gauge reads in MPa; an external round gauge and psi or bar scales are catalogue options. Thread is PT as standard, with G (BSPP) and NPT orderable; bracket included. AirTAC publishes flow as curves, not a single rating, so ask us to confirm sizing against the datasheet 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 GFR400C15MF1W FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so there is no single number we can honestly quote here. Give us your working pressure and flow requirement and we will confirm the sizing from the datasheet on request before you order.
The W in this code selects the 5 um element, intended where downstream components are sensitive: pilot valves, venturi vacuum generators, air motors and similar. The blank-grade version carries the standard 40 um element for general machine supply. Both use the same manual-drain bowl, 1/2 in PT ports and embedded square MPa gauge, and both adjust from 0.05-0.9 MPa (7-130 psi) with manual drain.
