AirTAC GFC600-20 Combination Unit (GFC60020C1K)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020C1K) 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 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC600-20 Combination Unit (GFC60020C1K)
The AirTAC GFC60020C1K is a genuine AirTAC two-unit treatment set combining a filter-regulator and a lubricator, and the K in the code 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, standard 40 um filtration 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, and the operating temperature range is -5 to 70 C (non-freezing) on compressed air only. Flow is published by AirTAC as curves rather than a single rating, so we confirm datasheet figures on request before you commit to a size.

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: 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 (GFC60020C1K) Is Used
Packaging machine air supply
Prepares air for a carton-packing machine's cylinder bank, with the fitted check valve helping hold the regulated circuit if the main supply drops mid-cycle.
Automated assembly fixture supply
Feeds regulated, lubricated air to robot end-of-arm clamping fixtures on an assembly cell, with the round MPa gauge giving a clear set-point check during changeover.
Process valve actuation skid
Conditions air for pneumatic quarter-turn valve actuators on a process skid, filtering water and particulate ahead of the positioner supply.
Is the AirTAC GFC600-20 Combination Unit (GFC60020C1K) the Right Set?
Choose this code over the plain GFC60020C1 when you want the reverse (check) valve fitted, which holds the downstream circuit if supply pressure is interrupted. Everything else decodes the same way: 600 size with the 3/4-inch PT3/4 port at the top of the G-series range, differential-pressure drain, 40 um filtration (5 um is the W-suffix variant), external round gauge on MPa scale, and PT thread as standard with G (BSPP) and NPT as catalogue options. As with all G-series units, flow appears in the catalogue as curves, not a single rating, so have us confirm sizing from the datasheet 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 (GFC60020C1K) FAQ
There is no single rated flow figure to quote: AirTAC publishes G-series flow as performance curves only. Send us your air demand and we will confirm the datasheet curve data for this 600-size, 3/4-inch set on request.
The K position in the code means a reverse (check) valve is fitted, which is the only difference from the plain C1 code. Filtration stays at the standard 40 um grade; for 5 um filtration you would move to the W-suffix code instead.
