AirTAC GFC300-08 Combination Unit (GFC30008AF1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AF1) 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 (GFC30008AF1)
The AirTAC GFC30008AF1 is a two-unit air-treatment set for compressed air: a filter regulator paired with a separate lubricator, so one station filters out water and particulate, holds a set downstream pressure and adds oil mist for downstream air tools. This configuration is size 300 with a 1/4 inch PT port, an automatic drain on the filter bowl, the standard 40 um filter element and the embedded square gauge scaled in MPa. The 300-size bowls are polycarbonate (PC).
This is a genuine AirTAC part from the G series, which covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and PT, G (BSPP) or NPT thread options. Maximum working pressure is 1.0 MPa (145 psi), the regulator adjusts 0.15-0.9 MPa (20-130 psi) on this automatic-drain version, and operating temperature is -5 to 70 C, non-freezing. Flow in this series is published as curves rather than a single rating, so we confirm the 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 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 (GFC30008AF1) Is Used
CNC machining center air supply
Conditions the shop-air feed to a CNC machining center's tool-clamp and chip-blow circuits: water and swarf-laden particles are removed, clamp pressure is held at the set value, and the lubricator feeds oil mist to the pneumatic clamp cylinders.
Packaging line case erector
Sits on the air drop to a case-erector or carton-sealing station on a packaging line, where clean, regulated air keeps vacuum cups and box-flap cylinders working consistently shift after shift and the oil mist extends cylinder seal life.
Assembly bench impact tools
Feeds impact wrenches and nutrunners at an assembly bench: the 40 um element stops rust and pipe scale reaching the tools, the regulator sets torque-consistent working pressure, and the lubricator delivers the oil mist these tools expect.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AF1) the Right Set?
Size 300 with a 1/4 inch PT port sits mid-range in the G series; step down to size 200 or up to 400 or 600 when the circuit needs a different port or flow level. This code carries the automatic drain, a good default for lines that run unattended; manual-drain and differential-pressure-drain variants exist if you prefer a set-and-inspect bowl. The element is the standard 40 um grade, with a 5 um W-code version available. The gauge is the embedded square type in MPa; an external round gauge with a psi or bar scale can be ordered instead. PT is the standard thread, with G and NPT as catalogue options. Because flow is published as curves and not a single rated figure, 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 (GFC30008AF1) FAQ
AirTAC publishes flow for the G series as performance curves, not as a single rated figure, so there is no honest one-number rating we can print. Tell us your line pressure and the flow your actuators or tools need, and we will confirm the sizing against the datasheet curves on request before you order.
The A in this code sets the automatic drain, which expels collected condensate from the filter bowl without anyone opening it, suiting unattended or hard-to-reach installations. The alternative decodes are manual drain, where an operator opens the bowl, and the default differential-pressure drain, which responds to the pressure drop across the element. All three share the same 0.15-0.9 MPa regulation range on this family.
