Airtac GFR Filter Regulator GFR400C15MC1
The AirTAC GFR Filter Regulator GFR400C15MC1 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 GFR400C15MC1
GFR400C15MC1 is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. A 40 um element, the standard grade, strips water and particulate from compressed air, and the regulator holds a set pressure anywhere in the 0.05-0.9 MPa (7-130 psi) span that applies to the manual-drain version. Condensate collects in the polycarbonate bowl and is released by opening the manual drain. The port is PT1/2, the standard thread for this series, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). An external round pressure gauge with MPa scale (code C1) is fitted and a mounting bracket is included.
This is a genuine AirTAC part. Across the series you can choose sizes 200-600, ports from 1/8 to 1 in, differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge styles and scales, G or NPT threads, and a check-valve variant (code K). Flow is published as curves rather than one rating, so we confirm sizing and supply the datasheet 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 GFR400C15MC1 Is Used
Robot gripper air supply
Set-and-monitor point-of-use pressure for the gripper and tool-changer actuators on a robotic handling cell, with the MPa gauge letting technicians read the setting at a glance.
Maintenance workshop air drops
Filtered, regulated air at workshop drop points feeding impact wrenches, blow guns and air ratchets, where the manual drain is bled during routine workshop checks.
Control panel actuator feed
Clean, regulated air to the positioner and actuator cluster on a process skid or control panel, with the included bracket making panel or frame mounting straightforward.
Is the Airtac GFR Filter Regulator GFR400C15MC1 the Right Unit?
Size 400 with a 1/2 in PT port serves heavier branch lines in the GFR range (sizes 200-600, ports 1/8-1 in); match the size to the air demand of the circuit and we will verify it against the published flow curve before you order. The manual drain suits installations where an operator can bleed the bowl on a routine walk-round; choose the automatic or differential-pressure drain codes for hands-off condensate removal. The 40 um element is the standard grade; step to 5 um (code W) for finer protection. The round gauge reads in MPa; psi and bar scale options exist, as do G and NPT threads and a no-bracket code (J).
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 GFR400C15MC1 FAQ
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we deliberately do not state a figure here. Give us your inlet pressure, target set pressure and demand, and we will confirm the right size from the datasheet on request.
40 um is the standard grade and suits general actuator and tool circuits. The 5 um option (code W in the model) is the finer grade for protecting precision components and small-bore circuits. Both are catalogue options on this same size 400, 1/2 in body, so you can move between them by code.
