Airtac GFR Filter Regulator GFR300C10MJF1W
The AirTAC GFR Filter Regulator GFR300C10MJF1W 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 GFR300C10MJF1W
GFR300C10MJF1W is a genuine AirTAC G-series filter regulator offering filtration and regulation in one body, sized 300 with a PT3/8 in port. The W in the code selects the fine 5 um filter element instead of the standard 40 um grade, for duties that need cleaner air. This configuration also has a manual drain bowl, no mounting bracket (J code), and an embedded square pressure gauge on MPa scale. With the manual drain, the regulator covers 0.05-0.9 MPa (7-130 psi), and the bowl is PC (polycarbonate) at the 300 size.
This is a genuine AirTAC part from a series built in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus drain-type, gauge-style and PT, G or NPT thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm the datasheet numbers 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 GFR300C10MJF1W Is Used
Laboratory instrument air
Conditions the supply to pneumatic samplers and valve manifolds on an analytical instrument skid, where the 5 um element keeps particulates out of fine internal passages.
Paint booth gun feed
Regulates and polishes the air feeding spray guns at a coating booth, with the fine element helping protect the fluid nozzle from debris carried in shop air.
Pneumatic sensor air supply
Feeds air-jet sensors and ejection nozzles on a sorting machine, where a stable, finely filtered supply keeps the small orifices from blocking.
Is the Airtac GFR Filter Regulator GFR300C10MJF1W the Right Unit?
The 300 size with a 3/8 in port is the mid step of the G range; go to 400 or 600 for larger demand or to 200 for compact points of use. This W variant carries the 5 um element, the right choice ahead of sensitive components; the standard 40 um grade is fine for general cylinders and valves. Manual drain gives the widest span, 0.05-0.9 MPa (7-130 psi), at the cost of hand draining the bowl at intervals. The embedded square gauge reads in MPa, with psi and bar scales as catalogue options. Thread is PT as the standard, with G and NPT available to order, and the bracket is omitted but orderable. Because flow is published as curves and not a single rating, 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 GFR300C10MJF1W FAQ
AirTAC publishes G-series flow as curves rather than one rated number, so there is no single figure we can quote here. Give us your inlet pressure and air consumption and we will confirm the flow from the datasheet curves for your conditions on request.
W selects the 5 um filter element in place of the 40 um standard grade, for cleaner air ahead of sensitive equipment. Drain type, gauge scale and thread are separate decode choices on the same body, all listed in the catalogue.
