Airtac GFR Filter Regulator GFR400C15MC1WK
The AirTAC GFR Filter Regulator GFR400C15MC1WK 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 GFR400C15MC1WK
GFR400C15MC1WK 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 combines a 1/2 in PT port, a manual-drain polycarbonate bowl, a fine 5 um filter element, an external round pressure gauge scaled in MPa, and a built-in reverse (check) valve that helps hold downstream pressure if the supply drops. Manual drain means an operator opens the bowl drain to clear collected water, which suits installations that are checked regularly.
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, round or square 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 GFR400C15MC1WK Is Used
CNC machining center clamp air
Feeding filtered, regulated air to the tool-clamp and parts-clamp circuits on a machining center, where the 5 um element protects the clamping valves and the check valve helps the clamps hold position during a supply dip.
Robotic weld cell grippers
Supplying the gripper and clamping manifold of a robotic welding cell, where the regulator sets a stable working pressure and the reverse valve backs up the grip if shop air pressure falls.
Pneumatic test bench
Conditioning the supply to a workshop test bench that pressure-cycles pneumatic components, where fine 5 um filtration keeps debris out of the piece under test and the round MPa gauge reads the set pressure directly.
Is the Airtac GFR Filter Regulator GFR400C15MC1WK 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) depending on the flow your circuit needs. Drain: manual suits units an operator visits routinely; choose automatic (A) or the differential-pressure default where the bowl is hard to reach. Element: the 5 um (W) grade in this code gives finer protection for valves and cylinders; the standard 40 um grade suits general line supply. Gauge: this code carries an external round gauge in MPa; embedded square gauges 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 send us your flow and pressure targets and we will confirm sizing against the datasheet 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 GFR400C15MC1WK FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so there is no one number we can honestly quote here. Tell us your working pressure and required flow and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects a manual-drain bowl: an operator opens the drain to release collected water, which suits units that are checked on a routine round. The K fits a reverse (check) valve, so downstream pressure is held back if the upstream supply fails or drops. Automatic and differential-pressure drain versions and a no-valve version are available in the same series.
