Airtac GFR Filter Regulator GFR300C10MJF1
The AirTAC Airtac GFR Filter Regulator GFR300C10MJF1 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 GFR300C10MJF1
GFR300C10MJF1 is a genuine AirTAC G-series filter regulator, combining water and particulate filtration with pressure regulation in a single body. It is a size 300 unit with a PT3/8 in port, a manual drain bowl, the standard 40 um filter element, no mounting bracket (J code), and an embedded square pressure gauge on MPa scale. With manual drain, the regulating range is 0.05-0.9 MPa (7-130 psi), and the PC (polycarbonate) bowl suits this size.
This is a genuine AirTAC part from the G series, which runs in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and options for drain type, 5 um elements, gauge style and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. Flow appears in the catalogue as curves rather than one rated figure, so we confirm datasheet values 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.

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 GFR300C10MJF1 Is Used
Bottling line conveyor stops
Conditions the air feeding cylinder-actuated stopping and diverting gates on a beverage bottling conveyor, with the manual-drain bowl emptied during scheduled line cleaning.
Workbench assembly clamps
Feeds toggle and swing clamps at an assembly bench, where the embedded square MPa gauge lets operators set and check clamp pressure at a glance.
Machine tool pneumatic circuit
Regulates filtered air to the tool-change and clamping circuit of a CNC machining centre, protecting valves from bulk water and rust particles carried in shop air.
Is the Airtac GFR Filter Regulator GFR300C10MJF1 the Right Unit?
Size 300 with a 3/8 in port sits in the middle of the G range; step to 400 or 600 for higher demand or to 200 for compact drops. Manual drain means the widest adjustment span, 0.05-0.9 MPa (7-130 psi), with the bowl emptied by hand at service intervals; automatic or differential-pressure drains are options on the same size. The 40 um element is the standard grade for general plant air; select the W variant with a 5 um element where finer filtration is needed. The square gauge here is embedded and reads in MPa; psi and bar scales are catalogue options. Thread is PT as the standard, with G and NPT available to order, and the bracket is omitted but can be added. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR300C10MJF1 FAQ
AirTAC publishes flow for the G series as curves rather than a single rated figure, so we do not state one number here. Tell us your supply pressure and consumption and we will read the flow off the datasheet curves for your conditions on request.
The 40 um element in this model is the standard grade for general plant air ahead of cylinders and valves. Choose the 5 um W variant when feeding finer components such as paint equipment or precision nozzles. Both grades are catalogue options on the same body.
