AirTAC GC300-08 FRL Unit (GC30008AF3K)
The AirTAC AirTAC GC300-08 FRL Unit (GC30008AF3K) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/4" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-08 FRL Unit (GC30008AF3K)
The GC family combines three separate AirTAC units - filter, regulator and lubricator - so compressed air is cleaned, pressure-regulated and oil-mist lubricated in one installation. This GC30008AF3K is the 300 size with PT1/4 ports, an automatic drain on the filter bowl, the standard 40 um filter element, an embedded square gauge with a bar scale, and a reverse flow check valve fitted. Maximum working pressure is 1.0 MPa (145 psi); with the automatic drain, the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). The 300 filter bowl is PC (polycarbonate) and the unit operates from -5 to 70 C, non-freezing.
You are buying a genuine AirTAC part. Across the G series the same function is offered in 200/300/400/600 sizes with ports from 1/8 to 1 inch, PT standard threads plus G and NPT options, and a choice of drain type, filter grade, gauge style and scale, and check valve. Flow data appears as curves, not a single rating, so we confirm flow and datasheet details 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). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: AirTAC GC300-08 FRL Unit (GC30008AF3K)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-08 filter, GR300-08 regulator and GL300-08 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC300-08 FRL Unit (GC30008AF3K) Is Used
Packaging machine actuation
Supplies regulated, lubricated air to carton-forming, sealing and labeling cylinders along a packaging conveyor, with the bar-scale gauge matching the machine's metric documentation.
Bench assembly air tools
Feeds impact drivers, riveters and air nutscrewdrivers at an assembly station, where oil-mist lubrication and stable regulated pressure keep hand tools working consistently.
PLC-driven valve manifold panel
Conditions the air feeding a solenoid-valve manifold on an automated machine, with the fitted check valve helping preserve downstream pressure during brief supply interruptions.
Is the AirTAC GC300-08 FRL Unit (GC30008AF3K) the Right Station?
Step through the G series by size: the 300 body with PT1/4 ports suits general machine supply, with 400/600 for heavier demand and 200 for compact builds. The automatic drain keeps condensate off the bowl floor without manual draining; manual (M) and differential-pressure (blank) types exist. This version keeps the standard 40 um element for general-purpose protection, and its square gauge reads in bar - handy for machines documented in metric units; psi and MPa scales and the round external gauge are alternatives. PT is the standard thread, with G and NPT available as catalogue options. Since flow is published only as curves, ask us to confirm the sizing for 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
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- 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 the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008AF3K) FAQ
AirTAC states G-series flow as performance curves, not as a single rated value, so we do not publish a number on the page. Share your operating pressure and consumption and we will confirm the flow figures from the datasheet on request.
The F code fits the embedded square gauge and the scale 3 code sets it to bar. If your plant works in MPa or psi, the same unit is available with those scales, and a round external gauge is also a catalogue option.
