AirTAC GFC300-08 Combination Unit (GFC30008C1K)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008C1K) 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 (GFC30008C1K)
GFC30008C1K is an AirTAC G-series two-unit air-treatment set: a filter-regulator and a lubricator working as a pair on 1/4 in PT connections, with a reverse (check) valve fitted in the K variant. The filter-regulator removes water and 40 um particulate, holds downstream pressure steady across the 0.15-0.9 MPa (20-130 psi) adjustment range, and drains condensate by the standard differential-pressure action, while the lubricator meters an oil mist downstream. The round external gauge reads on the MPa scale. Bowls are polycarbonate at this size, maximum inlet pressure is 1.0 MPa (145 psi), and the working range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series comes in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options that include manual or automatic drains, a 5 um element, alternative gauge scales, and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will 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.
Model Code: AirTAC GFC300-08 Combination Unit (GFC30008C1K)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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 (GFC30008C1K) Is Used
Welding-fixture hold-down clamps
Feeding hold-down clamps on a welding fixture, where the fitted reverse/check valve blocks backflow toward the supply if the upstream line pressure drops.
Pneumatic manifold valve supply
Conditioning the air feeding a directional-control valve manifold on a production machine, with the check valve helping isolate the treated downstream side from supply disturbances.
Palletiser pusher circuits
Supplying the layer-forming pusher cylinders on a palletiser, with filtered, regulated, lubricated air and a round MPa gauge for operator checks.
Is the AirTAC GFC300-08 Combination Unit (GFC30008C1K) the Right Set?
Pick the size step (200/300/400/600) and port (1/8 in to 1 in) for the air demand of the circuit - this 300 set is sized around 1/4 in piping. The drain is the default differential-pressure type, with automatic and manual versions available as separate codes; the element is the standard 40 um. Compared with plain GFC30008C1, the K code adds a reverse (check) valve, so specify it wherever reverse flow through the set must be blocked. PT is the standard thread; G (BSPP) and NPT are catalogue options.
Because G-series flow is published as curves and not as one rated number, 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 (GFC30008C1K) FAQ
AirTAC publishes G-series flow capacity as curves rather than a single rated figure, so no number is stated here. Share your application details and we will confirm the datasheet flow curve and sizing for this 1/4 in set on request.
The K code fits a reverse (check) valve in the set, so reverse flow through the unit is blocked. The same set without K is listed as GFC30008C1.
