Airtac GFR Filter Regulator GFR300C08ANWK
The AirTAC GFR Filter Regulator GFR300C08ANWK 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 GFR300C08ANWK
The AirTAC GFR300C08ANWK is a filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This code decodes to a size-300 unit with a 1/4 inch PT port, the finer 5 um (W) filter element, an automatic drain, a reverse (check) valve, and no pressure gauge fitted. Maximum working pressure is 1.0 MPa (145 psi), the regulation range with this drain type is 0.15-0.9 MPa (20-130 psi), and the size-300 bowl is polycarbonate.
It is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 inch, PT as the standard thread and G (BSPP) or NPT as orderable options; element grade, drain type, gauge and check-valve choices vary by code. Operating temperature is -5 to 70 C, non-freezing. AirTAC publishes flow as curves rather than a single rating, so we confirm 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 GFR300C08ANWK Is Used
Hold-up circuits on palletiser valve islands
Feeding valve islands on a palletiser where the downstream circuit should keep its charge if the supply side is shut off: the check valve holds the regulated side while the 5 um element protects the island's pilot sections.
Fixture clamping on assembly fixtures
Regulated air to clamp cylinders on welded assembly fixtures; the 5 um element suits the fine pilot valves doing the sequencing, and the check valve keeps clamps from venting back through the unit during supply dips.
Robot gripper air on an assembly cell
Conditioning supply to robot end-of-arm grippers in an automotive assembly cell, where steady regulated pressure, finer filtration and automatic condensate handling support repeatable grip cycles.
Is the Airtac GFR Filter Regulator GFR300C08ANWK the Right Unit?
Size 300 with the 1/4 inch PT port fits medium-duty branch circuits; step to 400 or 600 for larger ports or to 200 for compact ones. This code combines the two option letters that matter most here: W for the 5 um element instead of the standard 40 um, and K for a reverse/check valve that blocks back-flow toward the supply. The A drain vents condensate automatically, suiting unattended drops. No gauge is fitted on this code; gauge and scale options exist on other GFR300 codes. Before ordering, ask us to confirm sizing: AirTAC publishes flow as curves, not a single rating, so we check the curve against your demand.
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 GFR300C08ANWK FAQ
AirTAC publishes G-series capacity as flow curves, not a single rated figure, so no one number is quoted. Share your flow and pressure demand and we will confirm the datasheet curve for this 1/4 inch PT, 5 um, auto-drain, check-valve configuration before you order.
Yes, on other GFR300 codes. With no gauge letter the unit carries the embedded square pressure gauge; C adds an external round gauge and F a square gauge, with scale options 1 (MPa), 2 (psi) and 3 (bar). This particular code is specified without any gauge, so leave it as is or pick the variant that carries the gauge you want.
