AirTAC GFR300-08 Filter Regulator (GFR30008ANW)
The AirTAC AirTAC GFR300-08 Filter Regulator (GFR30008ANW) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a automatic 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 GFR300-08 Filter Regulator (GFR30008ANW)
The GFR30008ANW is an AirTAC G-series filter regulator: one body removes water and particulate from the compressed air line and then regulates downstream pressure. This 300-size unit has a PT1/4 port, an automatic drain (A) that discharges condensate from the PC bowl without daily attention, and the W code fitting a 5 um filter element for finer filtration than the standard 40 um grade. With no gauge fitted (N), downstream pressure is set on the adjuster; the auto-drain adjustment range is 0.15-0.9 MPa (20-130 psi) against a 1.0 MPa (145 psi) maximum inlet, and the mounting bracket is included.
This is a genuine AirTAC part. GFR units come in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in; PT thread is standard, with G (BSPP) and NPT as orderable options, and drain type, filter grade, gauge and bracket are all selectable. Operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than one rated figure, so we confirm datasheet and flow 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.

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 GFR300-08 Filter Regulator (GFR30008ANW) Is Used
Blow-off nozzles on a bottling line
Supplying air knives and blow-off nozzles that dry containers on a bottling line, where the 5 um element helps keep small orifice nozzles from clogging.
Laboratory automation actuators
Regulating air to the small cylinders and grippers on lab automation equipment that needs finer-than-standard filtration at the point of use.
Vacuum ejector feed on robot cells
Feeding vacuum ejectors on robotic pick-and-place cells, where clean regulated supply air protects the ejector's internal channels.
Is the AirTAC GFR300-08 Filter Regulator (GFR30008ANW) the Right Unit?
Size and port step with the air demand: 300 with a 1/4 in PT port is the mid-range choice; step up to 400 or 600 for larger ports and more flow, or down to 200 for compact take-offs. The main choice here is filter grade: the W code gives a 5 um element for air feeding sensitive components, while the standard 40 um grade suits general circuit protection. The A drain suits unattended points of use; manual (M) and differential-pressure drains are the alternatives. A square gauge in MPa, psi or bar scale can be ordered in place of the N (no gauge) option. 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 (PT1/4" 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 GFR300-08 Filter Regulator (GFR30008ANW) FAQ
There is no single rated flow figure to quote: AirTAC publishes GFR capacity as flow curves. Tell us your flow and pressure requirements and we will confirm sizing from the datasheet on request before you order.
The 40 um grade is the standard choice for general circuit protection against water and coarse particles. The W code fits a 5 um element, intended for air feeding finer components such as nozzles, ejectors and instrumentation. Both are catalogue options at the same 300 size and 1/4 in PT port, so you order the grade the application needs.
