Airtac GFR Filter Regulator GFR400C15MN
The AirTAC GFR Filter Regulator GFR400C15MN 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 GFR400C15MN
The GFR400C15MN is an AirTAC GFR400 filter regulator: a filter and a pressure regulator combined in one body with a single polycarbonate drain bowl. 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 as part of routine maintenance. No gauge is fitted (N suffix), and since there is no J suffix the mounting bracket is included, so the unit can be fixed to a machine frame or prep plate. 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 G series covers 200, 300, 400 and 600 sizes with ports from 1/8in to 1in, and this 400 frame can be ordered with automatic or differential-pressure drainage, the finer 5 um element, a gauge, no bracket, G (BSPP) or NPT threads, and a check valve. Flow for the series 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 GFR400C15MN Is Used
Packaging line air drop
Filtered, regulated air at the head of a packaging line's 1/2in distribution drop, feeding sealers, labelers and case packers downstream, with the bracket mounting the unit to the line frame.
Maintenance workshop supply point
A regulated, filtered bench supply in a plant maintenance workshop, where technicians hook up air tools and test rigs from a single 1/2in outlet.
Control cabinet actuation feed
Air prep ahead of the solenoid valve bank that drives a machine's actuators, giving one clean, regulated supply point for the whole cabinet.
Is the Airtac GFR Filter Regulator GFR400C15MN the Right Unit?
Size the frame to the air demand of the line - 200, 300, 400 and 600 step up through ports from 1/8in to 1in - and this unit arrives with the 1/2in PT port and the included bracket for panel or frame mounting. Manual drainage suits points an operator drains on a schedule; automatic and differential-pressure drains are available on the same frame. The standard 40 um element is the general-purpose grade for plant air; order the W suffix instead where downstream valves and cylinders need the 5 um grade. No gauge is fitted, so add one with an MPa, psi or bar scale if a setpoint has to 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 GFR400C15MN FAQ
AirTAC publishes flow for the GFR series as performance curves rather than a single rated figure, so there is no one number we can honestly quote here. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet on request.
With no J suffix in this code, the mounting bracket is included. No gauge is fitted (N suffix), but the same frame can be ordered with a gauge in MPa, psi or bar scale, so ask us to quote the variant you need.
