Airtac GFR Filter Regulator GFR300C10MJC1WK
The AirTAC GFR Filter Regulator GFR300C10MJC1WK 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 GFR300C10MJC1WK
GFR300C10MJC1WK is a genuine AirTAC G-series filter regulator: filtration and pressure regulation in one body, sized 300 with a PT3/8 in port. This configuration carries a manual drain bowl, a fine 5 um filter element, a round external pressure gauge on MPa scale, and a built-in reverse (check) valve that keeps downstream pressure in place when the upstream supply is shut off. The bowl on the 300 size is PC (polycarbonate). Because the drain is manual, the regulator covers 0.05-0.9 MPa (7-130 psi).
AirTAC builds the G series in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus choices of drain type, 40 um or 5 um elements, gauge styles and PT, G or NPT threads. Max working pressure is 1.0 MPa (145 psi) and the operating temperature 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 conditions 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 GFR300C10MJC1WK Is Used
Pneumatic press cell
Feeds a bench-mounted pneumatic press where the 5 um element protects the direction valve and cylinder seals, and the check valve holds the set pressure if the plant supply drops.
Actuated process valve package
Supplies filtered, regulated air to a spring-return ball valve actuator on a process line, with the MPa round gauge letting technicians set and verify the actuator pressure directly.
Packaging machine air drop
Conditioning the air feed to a carton-sealing machine, where the manual-drain bowl is drained at each shift check and the fine element shields the sealing cylinders from water and fines.
Is the Airtac GFR Filter Regulator GFR300C10MJC1WK the Right Unit?
The 300 size with a 3/8 in port is the mid step of the G range; move to 400 or 600 for heavier air demand or down to 200 for light-duty drops. Manual drain gives the widest regulating span, 0.05-0.9 MPa (7-130 psi), but the bowl must be drained by hand; pick the automatic drain option where the unit sits out of reach. The 5 um element suits cleaner-air duties, while the standard 40 um element handles general plant air. The gauge here is the round external type on MPa scale; embedded square gauges and psi or bar scales are catalogue options. Thread is PT as the standard, with G and NPT available to order. The J code omits the mounting bracket, which can be added if needed. Since flow is published as curves, not one rated number, 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 GFR300C10MJC1WK FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number here. Send us your inlet pressure and air demand and we will confirm the flow figures from the datasheet for your conditions before you order.
The M in the code selects a manual drain bowl that you drain by hand. It also gives the widest regulator span, 0.05-0.9 MPa (7-130 psi). The same size is available with an automatic drain or the default differential-pressure drain if you prefer not to drain by hand.
