Airtac GFR Filter Regulator GFR400C15ANK
The AirTAC GFR Filter Regulator GFR400C15ANK 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 GFR400C15ANK
The GFR series is AirTAC's filter regulator: filtration and pressure regulation built into one body, so a single 1/2 in PT connection both cleans the compressed air and holds a steady outlet pressure. The K suffix of this 400-size unit means a reverse (check) valve is fitted in addition to the standard hardware. It has an automatic drain (A) that empties the polycarbonate bowl unattended, the standard 40 um element, and no gauge fitted (N). Maximum inlet pressure is 1.0 MPa (145 psi) and the outlet is adjustable 0.15-0.9 MPa (20-130 psi) on this automatic-drain version.
This is a genuine AirTAC part. G-series filter regulators come in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for manual or differential-pressure draining, a 5 um element, an embedded square gauge or external round gauge, a reverse (check) valve and G (BSPP) or NPT threads. Working temperature is -5 to 70 C (non-freezing) and a mounting bracket is included. Flow is published as curves rather than a single rating, so we confirm the 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 GFR400C15ANK Is Used
Pneumatic clamping fixture on a weld line
Filters and regulates the air to swing clamps on a automotive weld fixture, with the fitted check valve included as part of the circuit at the fixture drop.
Automated assembly cell drop
One 1/2 in conditioned supply point for a multi-station assembly cell whose pick-and-place and screwdriver modules share the same regulated air.
Plant air drop for actuated valves
Conditions the branch feeding quarter-turn actuators across a processing plant, combining filter, regulator and check valve in a single 400-size body.
Is the Airtac GFR Filter Regulator GFR400C15ANK the Right Unit?
Size 400 with a 1/2 in PT port is the mid step of the G-series range; move to 300 or 600 to match the line's air demand. The A selects the automatic drain for unattended installations - manual (M) and differential-pressure versions are also catalogued. This K variant carries a reverse (check) valve; the same unit is available without it by dropping the K. The 40 um element protects general plant equipment, while the W code gives a 5 um element. No gauge is fitted (N); an embedded square gauge or external round gauge with MPa, psi or bar scale can be ordered. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and the mounting bracket is included.
Because AirTAC publishes flow as curves rather than one rated number, 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 GFR400C15ANK FAQ
AirTAC does not publish a single rated-flow figure for this series - flow is given as characteristic curves against pressure. Tell us your inlet pressure and the demand of the equipment downstream and we will confirm the sizing from the datasheet on request.
K means a reverse (check) valve is fitted in this unit. The identical filter regulator without the check valve carries the code GFR400C15AN. If your circuit already includes its own check valve, the non-K version avoids duplicating it; if you want the valve function built into the conditioning unit, this K model does it in one body.
