AirTAC GFC600-25 Combination Unit (GFC60025NK)
The AirTAC AirTAC GFC600-25 Combination Unit (GFC60025NK) 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" ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC600-25 Combination Unit (GFC60025NK)
GFC60025NK is a genuine AirTAC G-series two-unit F.R.L. set: a 600-size filter regulator plus a separate 600-size lubricator, filtering, regulating and lubricating a compressed-air line on one 1 in (PT1) PT-threaded port. This build keeps the catalogue defaults - 40 um standard filter element, differential-pressure drain in a 600-size aluminium alloy bowl, standard regulator adjusting 0.15-0.9 MPa (20-130 psi), no gauge (N) - and adds a reverse (check) valve (K) to the regulator section. Maximum working pressure is 1.0 MPa (145 psi), the medium is compressed air, and the working temperature range is -5 to 70 C, non-freezing.
This belongs to the largest G-series size; the same two-unit function is available in 200, 300, 400 and 600 sizes with 1/8 to 1 in ports. Across the range you can specify 5 um or 40 um filtration, automatic, manual or differential-pressure drains, embedded square or external round gauges in MPa, psi or bar, and PT, G (BSPP) or NPT threads. Flow is published as curves rather than a single figure, so we confirm datasheet and sizing details 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.

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: GFR600-25 filter regulator and GL600-25 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 GFC600-25 Combination Unit (GFC60025NK) Is Used
Packaging machine seal jaws
Supply to sealing-jaw and hold-down circuits on a carton packaging machine, built with the reverse (check) valve specified for the machine's pneumatic circuit.
Distribution centre sorting gates
Regulated, lubricated air for diverter gates and pusher cylinders on a parcel sorting conveyor at a distribution centre, fed from a single 1 in trunk connection.
Furniture plant nailer lines
A line-side conditioning point for nailer and stapler drops in a furniture plant, using the 40 um element and differential-pressure drain for general air quality.
Is the AirTAC GFC600-25 Combination Unit (GFC60025NK) the Right Set?
Choose the 600 size with its 1 in (PT1) port for trunk lines and multi-drop distribution; the 200/300/400 sizes with 1/8 to 3/4 in ports cover lighter circuits. The K code fits a reverse (check) valve to the regulator section, so order this build where the check valve is part of your circuit design. This unit drains differentially by default, with automatic or manual draining available as alternative builds, and filters at the 40 um standard grade (5 um via the W code). A gauge can be added as embedded square or external round in MPa, psi or bar scales, and PT is the standard thread with G (BSPP) and NPT to order. Since flow appears only as catalogue curves, ask us to confirm sizing against the datasheet before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1" 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 GFR600-25 filter regulator on its own.
AirTAC GFC600-25 Combination Unit (GFC60025NK) FAQ
None is published as a single rating: AirTAC gives G-series performance as flow curves only, so we do not state a fixed l/min or SCFM value here. Send us your pressure and consumption requirements and we will confirm the matching curve and datasheet figures for GFC60025NK on request.
K specifies that a reverse (check) valve is fitted to the regulator section. The rest of the build follows the catalogue defaults: 40 um filter element, differential-pressure drain in the aluminium alloy bowl, standard regulator with a 0.15-0.9 MPa (20-130 psi) range, no gauge, and PT thread.
