AirTAC GFC600-20 Combination Unit (GFC60020NK)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020NK) 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 (GFC60020NK)
The AirTAC GFC is a two-unit air-treatment set: a filter regulator combined with a separate lubricator, so one assembly filters water and particulate from compressed air, regulates downstream pressure and adds oil mist for air tools and cylinders. This GFC60020NK is the 600 size with PT3/4 ports, the 40 um standard element, a differential-pressure drain, no gauge (code N) and a reverse (check) valve fitted. The regulator adjusts 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and at 600 size the filter-regulator bowl is aluminium alloy. Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series is made in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as catalogue options, plus a choice of differential-pressure, automatic or manual drains and 40 um or 5 um elements. Flow data is published as curves rather than a single rating, so we confirm sizing and 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.
Model Code: AirTAC GFC600-20 Combination Unit (GFC60020NK)
| 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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 (GFC60020NK) Is Used
Carton-closing cylinders on a packaging line
Mounted at the machine drop, the set filters plant air, holds a steady regulator setting for the case-sealing cylinders and meters oil mist to keep their seals and bores lubricated through long shifts.
Pneumatic clamp fixtures in a weld cell
The filter regulator feeds the clamp circuit at a set pressure while the lubricator conditions the air for the clamping cylinders; the fitted check valve helps hold the circuit against supply dips.
Diverter and gate actuators on conveyor runs
Installed on the 3/4 in branch feeding conveyor diverters, it removes water and scale from the plant supply, keeps actuator pressure consistent between stations and lubricates the gate cylinders.
Is the AirTAC GFC600-20 Combination Unit (GFC60020NK) the Right Set?
Step up or down through the G-series sizes (200 to 600) and port codes (1/8 in to 1 in) to match the pipe bore and air demand of the machine; 600 size with PT3/4 suits heavier plant air drops. On drain: differential-pressure is the default here, automatic (A) discharges condensate without an operator and manual (M) gives a wider 0.05-0.9 MPa regulator range. The 40 um element is the standard choice; specify W for the 5 um grade where finer protection is needed. The N code on this unit means no gauge is fitted; variants without N carry an embedded square gauge, with an optional external round gauge in MPa, psi or bar scales. PT is the standard thread, with G and NPT orderable options.
Because G-series flow is published as curves and not as a single rated figure, ask us to confirm sizing against 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 (GFC60020NK) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no single number is quoted here. Send us your line pressure, port size and air demand and we will confirm the flow and datasheet figures for this exact model on request.
The N in the code means the set is supplied without a gauge. If you want a reading at the unit, choose a GFC600 variant without the N: those carry an embedded square gauge, and an external round gauge is available with MPa, psi or bar scales.
