Airtac GFR Filter Regulator GFR300C10MJF1WK
The AirTAC GFR Filter Regulator GFR300C10MJF1WK 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 GFR300C10MJF1WK
The GFR300C10MJF1WK combines filtration and pressure regulation in a single AirTAC G-series body. This 300-size unit carries a 3/8in PT port as standard (G/BSPP and NPT are orderable thread options). The M code selects a manual drain on the polycarbonate bowl, W selects the 5 um element in place of the 40 um standard, and J means the mounting bracket is not supplied. The embedded square pressure gauge reads in MPa, and K fits a reverse (check) valve so downstream air cannot back-feed through the unit. Supply pressure is rated to 1.0 MPa (145 psi) and, with this manual-drain version, the outlet adjusts from 0.05 to 0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part in the GFR300 series. The G platform runs from 200 to 600 size with ports from 1/8in to 1in, drain choices (differential-pressure, automatic, manual), 40 um or 5 um filtration, gauge and bracket options, and a low-pressure type on request. Flow for filter regulators is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

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 GFR300C10MJF1WK Is Used
Pneumatic fixture clamping on a machining centre
Feeds the clamp circuit on a VMC, filtering shop air to 5 um and holding a steady clamp pressure, with the check valve stopping back-bleed between cycles.
Air prep for a CNC tool-change circuit
Conditions the air supply ahead of the tool-changer cylinders and solenoid valves, removing water and fine particulate before it reaches the directional valves.
Packaging line diverter gates
Sits before the valves that cycle pusher and gate cylinders on a packaging conveyor, keeping line pressure stable across a full production shift.
Is the Airtac GFR Filter Regulator GFR300C10MJF1WK the Right Unit?
Step the size up or down (200 to 600) to match the port and flow path your line needs; 300 with a 3/8in PT port is the mid-range choice. Because flow is published as curves, not a single rating, send us your demand and we will confirm sizing against the datasheet before you order. Choose manual drain where an operator can vent the bowl during routine checks; automatic or differential-pressure drains suit unattended duty. Keep the 5 um element where finer prefiltration matters, and note the check valve blocks backflow from the downstream side. The gauge here is the embedded square type with an MPa scale; external round gauges and psi/bar scales are options. PT is the standard thread - order G (BSPP) or NPT explicitly - and add a bracket if the unit mounts away from a wall or manifold.
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 GFR300C10MJF1WK FAQ
AirTAC publishes flow for the G series as curves rather than one rated figure, so we do not quote a single number here. Tell us your air demand and we will confirm the datasheet figures and sizing for this 3/8in unit on request.
The M code selects a manual drain: an operator vents the bowl as part of routine checks. With a manual drain the outlet adjusts 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain variants adjust 0.15-0.9 MPa (20-130 psi).
