Airtac GFR Filter Regulator GFR300C15AJF1WK
The AirTAC GFR Filter Regulator GFR300C15AJF1WK 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 GFR300C15AJF1WK
The GFR300C15AJF1WK is an AirTAC GFR300 filter-regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubrication stage. This 300-size unit takes 1/2 in PT ports (PT is the standard thread for this code), drains its polycarbonate bowl automatically, carries the finer 5 um filter element, and has an embedded square pressure gauge scaled in MPa. The K option adds a reverse (check) valve that holds downstream pressure if the upstream supply fails. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with the automatic drain, and the working temperature range is -5 to 70 C.
This is a genuine AirTAC part from the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in. Across the range you can specify differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar, G (BSPP) or NPT threads, a mounting bracket and a reverse valve. Rated flow is published only as characteristic curves, not as a single figure, so send us your operating conditions and we will confirm sizing and provide the datasheet 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 GFR300C15AJF1WK Is Used
Pneumatic clamping station
Air prep for a clamping or riveting fixture at a machining cell: the MPa gauge lets the setter verify clamping pressure at the point of use, and the check valve holds the clamp if the main supply is shut down.
Packaging machine supply
Conditioning air for case packers and wrapping machines on a packaging line: the 5 um element guards directional control valves and cylinders from particulate, and the automatic drain clears condensate through continuous shifts.
Actuated process valves
Feeding air to actuated ball and butterfly valves on a process skid: filtered, regulated air keeps the actuators inside their rated pressure, and the automatic drain copes with humid compressor air.
Is the Airtac GFR Filter Regulator GFR300C15AJF1WK the Right Unit?
Size the unit on the air your downstream equipment actually consumes: 300 with 1/2 in PT ports is the mid range, stepping up to 400 or 600 adds port and flow capacity, while 200 or 300 serve lighter circuits. The automatic drain suits unattended, multi-shift installations; a manual drain variant needs operator attention but allows regulation down to 0.05 MPa (7 psi). The 5 um element (W) here protects finer valves and tools, against the 40 um standard element. The square MPa gauge is fitted; round external gauges in other scales can be ordered. The check valve blocks backflow from the downstream side. PT is the standard thread and G (BSPP) or NPT are order options; a bracket is optional and omitted in this code. Because AirTAC publishes flow as curves rather than 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 GFR300C15AJF1WK FAQ
AirTAC publishes flow for the GFR300 as characteristic curves rather than one rated figure, so we do not quote a single number. Share your upstream pressure and the air consumption of the equipment you are supplying, and we will confirm sizing from the datasheet on request.
The F1 option fits the embedded square pressure gauge with MPa scale so pressure can be read and set locally, and the K option fits a reverse (check) valve that holds downstream pressure if supply is interrupted. Both are order choices across the GFR300 range, alongside drain type, element grade and thread.
