About the AirTAC GC300-08 FRL Unit (GC30008F3W)
The GC30008F3W is AirTAC's three-piece F.R.L. combination in size 300 with PT1/4 ports, and the W suffix upgrades the filter to the 5 um element instead of the standard 40 um grade. Combined with differential-pressure drainage, standard-range regulation (0.15-0.9 MPa / 20-130 psi with this drain type) and a square bar-scaled gauge, the set delivers finer filtered, regulated and lubricated compressed air in one assembly. The 300-size filter and lubricator bowls are polycarbonate. Medium is compressed air; maximum working pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part sold through our distribution. Across the GC family you can pick sizes 200, 300, 400 and 600, ports from 1/8-inch to 1-inch, G (BSPP) or NPT threads, manual or automatic drains, 40 um or 5 um elements and MPa, psi or bar gauges. AirTAC publishes flow as curves rather than a single rated number, so we confirm datasheet figures for your application 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.

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 (GC30008F3W) Is Used
Laboratory automation fixtures
Actuated clamps and lifters on lab automation benches take 5 um filtered, regulated air from this set, keeping finer particulate away from small valves and cylinders.
Precision jig clamping station
Jig and fixture clamps on a machining cell run on cleaner-than-standard air from this F.R.L., with the regulator holding the clamp force setting and the lubricator servicing the cylinders.
Sorter modules in intralogistics
Diverter and pusher modules in a parcel sorter use conditioned PT1/4 air from this set, with the 5 um element suiting the compact valve islands fitted to modern sorter frames.
Is the AirTAC GC300-08 FRL Unit (GC30008F3W) the Right Station?
Match the GC size to your port and air demand: this size 300 set is ported PT1/4. The differential-pressure drain keeps the regulator range at 0.15-0.9 MPa (20-130 psi); choosing a manual drain would extend it down to 0.05 MPa (7 psi). The key choice here is filtration: the W element's 5 um grade suits circuits that see finer contamination than the standard 40 um element is intended for. The F3 suffix gives the square gauge with a bar scale (1 = MPa, 2 = psi). PT is the standard thread; G (BSPP) and NPT are catalogue options to order.
Flow is published as curves, not a single rating, so ask us to confirm the sizing against your application before you order.
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 (GC30008F3W) FAQ
Yes. AirTAC publishes GC series flow as curves rather than a single rated figure, so we do not state a number here. Share your line pressure and air demand and we will confirm the correct size from the datasheet on request.
The W suffix changes the filter element from the standard 40 um grade to 5 um, giving finer particulate removal ahead of the regulator and lubricator. Drainage, regulation range, gauge and ports are otherwise as decoded for this size 300, PT1/4 configuration.
