AirTAC GFC600-20 Combination Unit (GFC60020C1WK)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020C1WK) 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 PT3/4" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC600-20 Combination Unit (GFC60020C1WK)
The AirTAC GFC60020C1WK is a genuine AirTAC two-unit treatment set pairing a filter-regulator with a lubricator. The W marks 5 um fine filtration, and the K means a reverse (check) valve is fitted. This 600-size unit has a PT3/4 port (PT is the standard thread; G and NPT are catalogue options), a differential-pressure drain and an external round gauge reading in MPa. Maximum working pressure is 1.0 MPa (145 psi), with regulator adjustment from 0.15 to 0.9 MPa (20-130 psi) on the differential-pressure drain version.
This is a genuine AirTAC part. At 600 size the bowls are aluminium alloy, the temperature range is -5 to 70 C (non-freezing), and the medium is compressed air only. Flow figures appear in the catalogue as curves rather than a single rating, so ask us to confirm the datasheet numbers before ordering.

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 GFC600-20 Combination Unit (GFC60020C1WK)
| GFC600 | G-series two-unit set, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GFR600-20 filter regulator and GL600-20 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 GFC600-20 Combination Unit (GFC60020C1WK) Is Used
Trailer air-prep panel
Conditions air for a fleet-maintenance bay's trailer brake-test and door-actuation rig, with fine filtration ahead of sensitive test connections.
Tire-making machine supply
Feeds regulated, lubricated air to a tire-building machine's bladder and clamp circuits, with the check valve helping the circuit hold state between cycles.
Injection-mould ejection circuit
Prepares air for an injection-moulding machine's ejector and core-pull pneumatics, filtering to 5 um and holding a stable regulated set point.
Is the AirTAC GFC600-20 Combination Unit (GFC60020C1WK) the Right Set?
This is the most fully specified code in the 600 two-unit range: it combines the W fine-filtration grade (5 um versus the standard 40 um) with the fitted reverse (check) valve, on top of the 3/4-inch PT3/4 port, differential-pressure drain, external round MPa gauge and standard PT thread (G and NPT as catalogue options). Choose it when you need both cleaner air and check-valve protection on the same supply. As with every G-series unit, flow is published as curves rather than a single rating, so have us confirm datasheet sizing for your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/4" 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 aluminium-alloy bowls on the GFC600 suit harsher environments than PC bowls. 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 GFR600-20 filter regulator on its own.
AirTAC GFC600-20 Combination Unit (GFC60020C1WK) FAQ
AirTAC does not publish a single rated flow figure for the G-series, only performance curves, so we do not state a number here. Ask us and we will confirm the datasheet curves for this 600-size, 3/4-inch set against your air demand on request.
The only decode difference is the K position, which adds a fitted reverse (check) valve to the set; filtration stays at 5 um and everything else is unchanged. If you do not need check-valve protection, the plain W code covers the same filtration and regulation.
