AirTAC GFC300-10 Combination Unit (GFC30010AC1K)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AC1K) 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 (GFC30010AC1K)
GFC30010AC1K is a two-piece AirTAC G-series set combining a filter regulator and a lubricator, with a reverse (check) valve fitted so flow cannot run backwards through the set. This size-300 unit filters to the standard 40 um grade, 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).
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). The same set is available without the check valve, and the GFC family spans sizes 200, 300, 400 and 600 in 1/8 to 1 inch ports with drain, filter-grade, gauge and thread options. Flow is published as curves rather than a single rated figure, 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 (GFC30010AC1K) Is Used
Shared valve-manifold branch
Protects a branch tapped off a shared plant air main that feeds directional control valves; the fitted reverse (check) valve blocks backflow from downstream toward the set.
Pneumatic press hold-downs
Feeds the hold-down cylinders of a small pneumatic press with filtered, regulated, lubricated air, while the external MPa gauge supports quick pressure verification during setup.
Lab test-rig actuators
Supplies a laboratory test rig's air actuators; the 40 um element and automatic drain keep particulate and condensate out of the rig between test runs.
Is the AirTAC GFC300-10 Combination Unit (GFC30010AC1K) the Right Set?
The K suffix is the only difference from the GFC30010AC1: it adds a reverse (check) valve, useful when a set feeds a branch where downstream backflow is possible. Otherwise the decodable choices are the same - sizes 200 to 600 with 1/8 to 1 inch ports, the 40 um standard element versus the 5 um (W) option, and automatic, manual or differential-pressure drains. Flow is published as curves, so ask us to confirm sizing against your application before ordering.
The C1 suffix specifies the external round gauge in MPa, with psi and bar scales as catalogue alternatives. PT is the standard thread; G (BSPP) and NPT are orderable 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 (GFC30010AC1K) FAQ
No single rated flow figure is quoted, because AirTAC publishes G-series flow as performance curves rather than one number. Send us your application details and we will confirm the sizing against the datasheet on request.
K fits a reverse (check) valve in the set; without it the GFC30010AC1 is otherwise identical - same 40 um filter, automatic drain, PT3/8 ports and external MPa gauge. The check valve prevents reverse flow through the set, and the regulation range stays 0.15-0.9 MPa (20-130 psi) with the automatic drain.
