Airtac GFR Filter Regulator GFR300C10AJF1WK
The AirTAC Airtac GFR Filter Regulator GFR300C10AJF1WK 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 GFR300C10AJF1WK
The AirTAC GFR series filters and regulates compressed air in a single body: a drain bowl removes water and particulate, and a regulator sets downstream pressure. This configuration is the 300 size with a 3/8 inch PT port, an automatic drain, the finer 5 um element (W), an embedded square gauge with MPa scale, and a reverse (check) valve fitted (K) to prevent backflow through the unit. The J suffix means this version is ordered without a mounting bracket.
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 inch. Maximum working pressure is 1.0 MPa (145 psi); on this automatic-drain version the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). The ambient temperature range is -5 to 70 C, non-freezing, and the 300 size bowl is PC (polycarbonate). Alternatives in the series include manual or differential-pressure drains, a 40 um element, psi or bar gauge scales, and G or NPT threads. Flow data is published as curves, so we confirm flow and datasheet figures 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 GFR300C10AJF1WK Is Used
Pneumatic valve manifold supply
Filtering, regulating and check-valve protecting the air feed to a solenoid valve manifold on an automation line, so backflow cannot disturb the set pressure upstream of the valves.
Palletiser gripper circuit
Conditioning air to vacuum and clamp grippers on a palletiser, with the check valve helping hold the regulated circuit against pressure reversals during fast cycle changes.
Test rig pressure control
Supplying finely filtered, regulated air to a bench test rig for pneumatic components, with the MPa gauge and check valve supporting stable, repeatable setpoints.
Is the Airtac GFR Filter Regulator GFR300C10AJF1WK the Right Unit?
This is the most fully optioned 300-size GFR variant in this listing: 3/8 inch PT port, automatic drain (A), 5 um element (W), square MPa gauge (F1) and check valve (K). If backflow is not a concern, the same unit without K is GFR300C10AJF1W; for coarser standard filtration drop the W for 40 um. Downsize to 200 or upsize to 400/600 where port size or demand differs. Drain alternatives are manual (M) or the differential-pressure default. Thread is PT standard, with G (BSPP) and NPT as orderable options; J means no bracket is included.
Because flow for this series is published as curves rather than a single rating, ask us to confirm sizing against your application before you order.
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 GFR300C10AJF1WK FAQ
AirTAC publishes flow for the G series as curves rather than one rated figure, so there is no single rated l/min or SCFM value we can quote. Share your application and we will confirm the flow data from the datasheet and check whether size 300 at 3/8 inch is right for you before ordering.
K means a reverse (check) valve is fitted, which blocks backflow through the unit. Choose it where downstream pressure reversals could disturb your regulated setting - for example on fast-cycling actuator or gripper circuits. Without K, the equivalent unit is GFR300C10AJF1W, identical apart from the check valve.
