AirTAC GFC300-08 Combination Unit (GFC30008ALF1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ALF1) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008ALF1)
GFC30008ALF1 is a genuine AirTAC GFC two-unit air-preparation set for compressed air: a filter-regulator that removes water and particulate and holds downstream pressure, paired with a separate lubricator that meters oil mist to downstream air tools and cylinders. This 300-size set has PT1/4 ports, an automatic drain, the standard 40 um element and the low-pressure regulator type for circuits run at reduced set-points. It carries the embedded square pressure gauge scaled in MPa.
You are buying a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with PT, G (BSPP) or NPT threads, 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and square or round gauges in MPa, psi or bar scales. The filter-regulator bowl on this 300 size is polycarbonate. Inlet pressure is rated to 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm sizing, the low-pressure set-point band and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC300-08 Combination Unit (GFC30008ALF1) Is Used
Food packaging sealers
Conditions air for the clamp and sealing cylinders on a tray-sealing machine, where the low-pressure type suits the reduced-pressure actuation circuit.
Wire and cable winding machines
Supplies filtered, regulated, lubricated air to the tensioner and guide cylinders on a spooling line, with the automatic drain handling condensate.
Pneumatic test benches
Prepares low-pressure regulated air for the actuation side of a leak-test bench, with the embedded MPa gauge giving a direct read at the set-point.
Is the AirTAC GFC300-08 Combination Unit (GFC30008ALF1) the Right Set?
This 300-size set with 1/4 in ports is the mid frame of the G series range of 200, 300, 400 and 600 sizes - match the frame to your port and flow needs. The L in the code selects the low-pressure regulator type for reduced set-point circuits (set-point band confirmed from the datasheet on request); the standard type covers full-range regulation. The automatic drain clears condensate unattended, and the 40 um element suits general plant air with the W option for 5 um. The embedded square gauge here reads in MPa; round or psi/bar gauges are orderable. PT thread is standard on this code, with G (BSPP) and NPT as catalogue options to specify. Because flow is published as curves rather than a single rating, 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
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008ALF1) FAQ
We do not state a single rated flow because AirTAC publishes flow for the G series as curves, not one figure. Give us your line pressure, port size and downstream demand and we will confirm the flow curve and full datasheet figures for this model on request.
Yes. PT is the standard thread on this code, and the same GFC300 300-size set is available in the catalogue with G (BSPP) or NPT threads - simply order the corresponding thread variant. The filter grade, automatic drain, low-pressure type and square MPa gauge remain as decoded here.
