Airtac GFR Filter Regulator GFR400C15MNK
The AirTAC GFR Filter Regulator GFR400C15MNK 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 GFR400C15MNK
The GFR400C15MNK is an AirTAC GFR400 filter regulator: a filter and a pressure regulator combined in one body with a single polycarbonate drain bowl, and the trailing K suffix adds a check valve to the configuration. It is sized for 1/2in PT ports, uses the standard 40 um filter element, and the M suffix specifies manual drainage, so the bowl is emptied by hand on a maintenance schedule. No gauge is fitted (N suffix), and with no J suffix the mounting bracket is included for frame or panel fixing. Regulating range with manual drainage is 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi); working temperature is -5 to 70 C.
This is a genuine AirTAC part. The same 400 frame appears across the G series in 200, 300, 400 and 600 sizes with ports from 1/8in to 1in, and can be ordered with automatic or differential-pressure drainage, the 5 um element, a gauge, no bracket, G (BSPP) or NPT threads, with or without the check valve. Flow is published as performance curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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 GFR400C15MNK Is Used
Pneumatic gate valve actuator supply
Filtered, regulated air to a quarter-turn pneumatic valve actuator on a process line, mounted on the bracket beside the actuator with the check valve included as coded.
Assembly line station feed
A regulated, filtered 1/2in supply point serving the air tools and cylinders at a manual assembly station on a moving line.
Loading dock door drive air prep
Air prep for the pneumatic cylinders driving a high-speed dock door, with the bracket fixing the unit to the door frame and manual drainage fitting a dock checked each shift.
Is the Airtac GFR Filter Regulator GFR400C15MNK the Right Unit?
Walk the G series frames (200, 300, 400, 600) against the air demand of your line; this unit brings the 1/2in PT port, the included mounting bracket and the fitted check valve. Order the same code without the K suffix when your circuit does not call for a check valve. Manual drainage is right where an operator drains the bowl on schedule; automatic and differential-pressure drains exist on the same frame. The standard 40 um element suits general plant air - choose the W suffix for the 5 um grade where downstream components need finer air. No gauge is fitted, so add one with an MPa, psi or bar scale if a setpoint must be read at the unit. Threads are PT as standard with G (BSPP) and NPT as ordering options. Because rated flow is published as curves and not a single number, send us your flow requirement and we will confirm sizing against the AirTAC 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 GFR400C15MNK FAQ
Flow for the GFR series is published as performance curves rather than a single rated figure, so there is no one number we can honestly quote here. Send us your line pressure and air demand and we will confirm the sizing against the datasheet on request.
Only the trailing K suffix separates the two: this unit has a check valve fitted, while the GFR400C15MN does not. Port, thread, manual drain, 40 um element, included bracket and no gauge are identical on both.
