AirTAC GFC300-08 Combination Unit (GFC30008F1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F1) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008F1)
The GFC30008F1 is a two-piece air-treatment set from AirTAC's G series: a size 300 filter regulator paired with a size 300 lubricator on 1/4 in PT ports. The filter stage strips water and 40 um particulate into a polycarbonate bowl with a differential-pressure drain, the regulator holds downstream pressure anywhere in its 0.15-0.9 MPa (20-130 psi) adjust range, and the lubricator meters oil mist to downstream tooling. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. This configuration specifies the square gauge reading in MPa.
This is a genuine AirTAC part. The G two-piece sets are offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include manual or automatic drains, a 5 um element (code W), round external gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of PT. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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 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 (GFC30008F1) Is Used
Air nailers and staplers on a truss fabrication bench
Supplies the nail guns and staplers on a timber truss and frame bench. The filter keeps moisture and debris out of the tool air, the regulator pins the pressure for consistent fastener depth, and the lubricator feeds the driver mechanisms.
Pusher and gate cylinders on a food-grade conveying line
Runs the reject pushers and lane gates along a dry-goods packaging conveyor. Clean, regulated, oil-misted air keeps the compact cylinders cycling quickly and evenly through every shift.
Pneumatic presses at a small stamping and riveting cell
Feeds the bench-mounted pneumatic presses and riveters in a light metalworking cell. The regulator sets the press force repeatably, the 40 um element protects the cylinder seals, and the lubricator reduces wear under continuous duty.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F1) the Right Set?
Size 300 with 1/4 in PT ports is the mid step of the G range; move to size 400 if your demand runs near the limit of a 300. Drain choice: differential-pressure (this code, standard), automatic (A) for unattended drainage, or manual (M) - manual-drain versions widen the regulator adjust range to 0.05-0.9 MPa (7-130 psi). Element grade is 40 um standard or 5 um with code W. This code selects the square MPa gauge; round external gauges in psi or bar scales are ordered under their own codes. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options; a mounting bracket is optional. 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
- ✓ 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 (GFC30008F1) FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so no rated number is quoted here. Send us your working pressure and air demand and we will confirm the sizing from the datasheet curve on request before you order.
G units with a regulator can carry an embedded square gauge or an external round gauge, each in MPa, psi or bar scales. This code (F1) specifies the square gauge reading in MPa; round psi or bar versions are ordered under codes such as C2 and C3, so choose the scale your maintenance team reads.
