AirTAC GFC300-10 Combination Unit (GFC30010AC1)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AC1) 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 PT3/8" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010AC1)
GFC30010AC1 is a two-piece AirTAC G-series set combining a filter regulator and a lubricator: the air is filtered to the standard 40 um grade, regulated, then oil-mist lubricated downstream. This size-300 unit has PT3/8 ports, an automatic drain (A) on the filter bowl and an external round gauge scaled in MPa. With the automatic drain, the regulator adjusts 0.15-0.9 MPa (20-130 psi), and the gauge gives a direct pressure readout at the machine.
It is a genuine AirTAC part for compressed air, rated to a maximum working pressure of 1.0 MPa (145 psi) and -5 to 70 C (non-freezing). GFC two-unit sets come in sizes 200, 300, 400 and 600 with 1/8 to 1 inch ports and choices of drain, filter grade, gauge, thread and check valve. Flow appears as curves in the catalogue, so we confirm 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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010AC1) Is Used
CNC tool-change circuit
Prepares air for the tool-clamp and tool-change cylinders on a CNC machining centre; the automatic drain keeps condensate out of the circuit and the MPa gauge lets maintenance check line pressure at a glance.
Bottling-line diverters
Feeds the divert and stopper cylinders along a bottling conveyor, filtering to 40 um and carrying oil mist to the line actuators.
Welding-fixture clamps
Supplies regulated, lubricated air to the swing clamps on a welding fixture, with the round MPa gauge supporting routine pressure checks before each production run.
Is the AirTAC GFC300-10 Combination Unit (GFC30010AC1) the Right Set?
Size 300 with PT3/8 ports sits mid-range in the GFC family, which steps through sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch; match the step to the machine's air demand - flow is published as curves, not a single rating, so ask us to confirm sizing before ordering. This unit pairs the 40 um standard element with the automatic drain, which discharges condensate from the filter bowl without day-to-day manual draining; manual (M) and differential-pressure drains are the other decodable choices.
The C1 suffix adds an external round gauge scaled in MPa (psi and bar scales are the other catalogue choices), and no reverse valve is fitted. PT is the standard thread; G (BSPP) and NPT are orderable thread options.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010AC1) FAQ
We do not quote a single rated flow figure because AirTAC publishes G-series flow as performance curves. Tell us the application and line pressure and we will confirm the sizing against the datasheet on request.
The A suffix selects an automatic drain on the filter bowl, which discharges collected condensate without a manual draining routine. Differential-pressure drain is the default and manual drain (M) is the third option. The regulation range also depends on drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential drain, and 0.05-0.9 MPa (7-130 psi) with manual drain.
