Airtac GFR Filter Regulator GFR300C10AJC1WK
The AirTAC Airtac GFR Filter Regulator GFR300C10AJC1WK 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 GFR300C10AJC1WK
The AirTAC GFR series combines compressed-air filtration and pressure regulation in a single body. This GFR300 configuration is sized for a 3/8 in. PT port and pairs the W-coded 5 um filter element with a fitted reverse-flow check valve, so downstream air can vent back through the unit on exhaust. The polycarbonate bowl drains automatically, pressure is set on the built-in regulator and read on the external round gauge scaled in MPa, and rated inlet pressure is 1.0 MPa (145 psi) with a -5 to 70 C working range.
This is a genuine AirTAC part in the 300 size of the G series (sizes 200, 300, 400 and 600). Automatic, manual and differential-pressure drains, 40 um and 5 um elements, round or square gauges in MPa, psi or bar scales, G (BSPP) and NPT threads and the reverse-flow valve are all catalogue options. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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 GFR300C10AJC1WK Is Used
Fixture-clamping safety circuits
Fine-filtered, regulated air for safety clamping on a machining fixture, where the check valve allows the downstream side to vent back through the unit when the circuit exhausts.
Actuated process valves
Supplying pneumatically actuated butterfly and ball valves on a process skid, with 5 um filtration ahead of positioner and solenoid air and pressure set on the MPa gauge.
Form-fill-seal machine air
Regulated, finely filtered air to a form-fill-seal packaging machine's grippers and seal cylinders, with automatic condensate drainage between production runs.
Is the Airtac GFR Filter Regulator GFR300C10AJC1WK the Right Unit?
Sizes 200, 300, 400 and 600 step up in port and flow; this unit carries a 3/8 in. PT port. With automatic drain the regulator adjusts 0.15-0.9 MPa (20-130 psi); a manual-drain version widens the low end to 0.05 MPa. This code combines the W 5 um element with the K reverse-flow check valve - specify K where downstream air should vent back through the unit. Gauges are the embedded square type or an external round gauge with MPa, psi or bar scales; threads order as PT (standard), G (BSPP) or NPT; J omits the bracket. 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 GFR300C10AJC1WK FAQ
No single rated figure is quoted because AirTAC publishes G-series flow as curves. Send us your application details - upstream pressure, port size and demanded flow - and we will confirm sizing from the datasheet on request.
W selects the 5 um filter element instead of the 40 um standard, and K fits a reverse-flow check valve so downstream air passes back through the unit on exhaust. Both are catalogue options on the same 300-size body, which is also offered with manual or differential-pressure drains, square or round gauges, G or NPT threads and an optional bracket.
