Airtac GFR Filter Regulator GFR300C08ANK
The AirTAC GFR Filter Regulator GFR300C08ANK 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 GFR300C08ANK
The AirTAC GFR300C08ANK 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 standard 40 um filter element, an automatic drain that vents collected condensate on its own, 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 GFR300C08ANK Is Used
Directional valve stacks on packaging machines
Feeding the directional control valves on a carton-forming machine: the 40 um element keeps grit out of spool clearances, the regulator holds a steady set point, and the check valve stops downstream air back-feeding the supply drop.
Gate and stopper cylinders on bottling conveyors
Regulated supply to gate, divert and stopper cylinders along a bottling line, where the automatic drain clears condensate at unattended drops so bowls do not need walking the line each shift.
Point-of-use drop after a shop air header
Mounted at the wall drop of a machine-shop cell to filter and regulate branch air ahead of air tools and blow-off guns, with the check valve holding the downstream circuit if header pressure falls.
Is the Airtac GFR Filter Regulator GFR300C08ANK the Right Unit?
Stay on size 300 with the 1/4 inch PT port when your pipe run and duty suit that connection; step up to 400 or 600 for larger ports and higher curve positions, or down to 200 for compact circuits. The A drain suits unattended or hard-to-reach drops; choose M (manual) where an operator blows the bowl down on a schedule. The 40 um element is the standard grade - specify W for 5 um. K adds the reverse/check valve so downstream air cannot feed back toward the supply; this code has no gauge, though 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 actual 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 GFR300C08ANK FAQ
AirTAC publishes G-series capacity as flow curves, not as a single rated figure, so we do not quote a number. Send us your flow and pressure demand and we will confirm the datasheet curve for this 1/4 inch PT, 40 um, auto-drain, check-valve configuration before you order.
K fits a reverse (check) valve, so air cannot flow back through the unit toward the supply - useful where a downstream circuit must hold its charge. The rest of the code reads: A = automatic drain, N = no gauge, 08 = 1/4 inch PT port, and the standard 40 um filter element.
