AirTAC GFC300-08 Combination Unit (GFC30008N)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008N) 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 (GFC30008N)
The AirTAC GFC two-unit set pairs a filter-regulator with a lubricator, giving filtration, pressure regulation and oil-mist lubrication in one assembly. This GFC30008N is built for 1/4 in. PT ports, uses the differential-pressure drain that bleeds condensate as air flows through, the standard 40 um filter element, and no gauge. With differential-pressure drainage the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
It is a genuine AirTAC part, rated for compressed air at up to 1.0 MPa (145 psi) inlet and -5 to 70 C, non-freezing, with polycarbonate bowls at this 300 size. The GFC series spans sizes 200 to 600 with alternative drain types, a 5 um element option, gauge variants and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so we confirm flow 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. 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 (GFC30008N) Is Used
Packaging conveyor actuator supply
Dropping filtered, regulated and lubricated air to cylinder-driven pushers and diverters on a packaging conveyor; the differential-pressure drain bleeds condensate automatically as air passes through.
Plant drop for assembly benches
A workbench drop on a factory air ring: one two-unit set conditions the air for hand tools and small air cylinders, with the 40 um standard element matched to general plant air.
Pneumatic control panel feed
Conditioning the air feeding directional valves and pilot circuits inside a machine control cabinet, with the regulator holding a steady set point downstream of the set.
Is the AirTAC GFC300-08 Combination Unit (GFC30008N) the Right Set?
Choose the size step (200, 300, 400 or 600) against the port and air demand of the line; this set is size 300 with 1/4 in. PT ports. Drain options are differential-pressure (this set, the default), automatic (A) or manual (M); filtration is the standard 40 um element, with 5 um available as W; gauge variants add an embedded square or external round gauge on MPa, psi or bar scales if you want a visual set point. Thread is PT as standard, with G (BSPP) and NPT catalogue options. Because flow is published as curves rather than one 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 (GFC30008N) FAQ
Flow for the GFC300 is published as curves in the AirTAC datasheet, not as a single rated figure, so we do not state a number here. Send us your line pressure and air demand and we will confirm the curve and sizing from the datasheet on request before you order.
N means the set is supplied without a gauge, so the regulator is set to the downstream requirement without a pressure reading on the unit. Gauge variants in the GFC300 series add an embedded square gauge or an external round gauge on MPa, psi or bar scales if you want a visual indication.
