Airtac GFR Filter Regulator GFR400C15MF1WK
The AirTAC GFR Filter Regulator GFR400C15MF1WK 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 GFR400C15MF1WK
The AirTAC GFR series combines water and particulate filtration with pressure regulation in one body. The GFR400C15MF1WK is the 400 size with a PT1/2 port, a manual drain bowl, a 5 um element for finer filtration than the standard 40 um grade, an embedded square pressure gauge on an MPa scale, and a built-in reverse (check) valve that holds the downstream setting if the upstream supply is shut off. Maximum inlet pressure is 1.0 MPa (145 psi), the manual-drain regulation range is 0.05-0.9 MPa (7-130 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, offered as filters, regulators, lubricators, filter regulators and full three-unit F.R.L. sets, with automatic, manual or differential-pressure drains, 40 um or 5 um elements, G (BSPP) or NPT thread options and optional brackets. Flow is published as curves rather than a single rating, so we confirm exact figures from 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 GFR400C15MF1WK Is Used
CNC fixture clamping circuit
Regulate the supply to power clamps on a machining-centre fixture, holding one steady set pressure for the clamping valves while the 5 um element keeps fine particulate out of the pilot circuit.
Case palletizer grippers
Feed the gripper cylinders and vacuum generators on a case palletizing line; the built-in check valve holds the regulated pressure at the gripper circuit when the main air is isolated upstream.
Bottling line divert gates
Supply stop-and-divert gates on a bottling conveyor, where the manual drain lets an operator bleed accumulated water from the bowl as part of the start-of-shift walk-round.
Is the Airtac GFR Filter Regulator GFR400C15MF1WK the Right Unit?
Move up to the 400 size when the circuit needs a 1/2 inch port or when your flow sits near the top of the size 300 curve - send us the duty and we will confirm sizing against the curve before you order. Pick the manual drain where an operator walks the line and can bleed the bowl at shift start, or where the lowest regulation floor matters: manual drain allows 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains. The 5 um (W) element is the choice for pilot valves and cylinders that tolerate less particulate; the embedded square gauge reads in MPa. Thread is PT as standard, with G (BSPP) and NPT as catalogue options to order, and this code includes the mounting bracket.
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 GFR400C15MF1WK FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so we do not quote one number on the page. Tell us your line pressure and required flow and we will confirm sizing from the datasheet on request before you order.
A manual drain means someone bleeds the bowl by hand, which suits attended machines and gives the widest regulation range: 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for automatic or differential-pressure drains. Choose automatic if the unit sits in an unattended spot.
