About the AirTAC GC600-20 FRL Unit (GC60020NWK)
GC60020NWK is a genuine AirTAC G-series three-unit F.R.L. combination - separate filter, regulator and lubricator - that filters, regulates and oil-mist lubricates compressed air. The W suffix selects the finer 5 um filter element instead of the standard 40 um, and the K suffix fits a reverse/check valve so downstream pressure is held if the supply is interrupted. This is the size 600 body with a PT3/4 port, differential-pressure drain, standard-type regulator adjusting 0.15-0.9 MPa (20-130 psi), and no gauge fitted. Maximum working pressure is 1.0 MPa (145 psi), temperature -5 to 70 C (non-freezing); at size 600 the bowls are aluminium alloy.
This is a genuine AirTAC part from a series spanning sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, offered with automatic, manual or differential-pressure drains, 40 or 5 um filter grades, embedded square or external round gauges in MPa, psi or bar scale, and G (BSPP) or NPT threads. Flow is published as performance curves rather than a single rated figure, 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 combination has no separate bracket code — the three 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 GC600-20 FRL Unit (GC60020NWK)
| GC600 | G-series F.R.L. combination, 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF600-20 filter, GR600-20 regulator and GL600-20 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC600-20 FRL Unit (GC60020NWK) Is Used
Paint spray booth atomizing air
Supplying finely filtered, regulated and lubricated air to spray guns and atomizing headers in an industrial paint line, where the 5 um element helps protect nozzle performance.
Laboratory automation actuators
Conditioning air for the small cylinders and valves on lab automation and sample-handling equipment, with finer 5 um filtration and a check valve holding pressure through supply dips.
Process pilot valve supply
Feeding pilot-air to banks of process control valves in a plant, where clean 5 um air and a stable regulated pressure support reliable valve actuation.
Is the AirTAC GC600-20 FRL Unit (GC60020NWK) the Right Station?
Pick this code when a 3/4 in PT supply must also be cleaned to 5 um - useful where fine particulate can upset downstream valves, probes or nozzles - and you want the check valve of the K suffix to hold regulated pressure. The 5 um element loads faster than the standard 40 um element on dirty air, so review your drain choice: this code uses the differential-pressure drain, while automatic-drain codes reduce the need for operator attention. A gauge is not fitted on the N suffix; gauge versions with square or round dials in MPa, psi or bar scale exist in the series. PT is the standard thread, with G (BSPP) and NPT as ordered options. Because flow is published only as curves and not a single rating, ask us to confirm the flow for your duty against the datasheet 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
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter 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 station above freezing (-5 to +70 °C, unfreeze).
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC GC600-20 FRL Unit (GC60020NWK) FAQ
Flow for the G-series is published as performance curves, not a single rated figure, so there is no one number to quote. Send us your line pressure, port size and downstream demand and we will confirm the flow for this unit from the datasheet on request before you order.
The W suffix changes the filter element to 5 um for applications where finer particulate removal matters, such as spray air, instrumentation or pilot valves. The standard 40 um element suits general plant air and loads more slowly on dirty supplies, so the choice depends on how sensitive your downstream equipment is.
