AirTAC GFC600-20 Combination Unit (GFC60020AC1K)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020AC1K) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC600-20 Combination Unit (GFC60020AC1K)
The AirTAC GFC600-20 is a two-unit air-treatment set that combines a filter-regulator with a lubricator, so one assembly removes water and particulate from the compressed air, holds the downstream pressure steady, and adds oil mist for air tools and cylinders. In this configuration the 600 size is fitted with a PT3/4 (3/4 in) port, the filter drains automatically, the standard filtration grade is 40 um, and a round external gauge on the MPa scale lets you read and set the regulated pressure directly. A reverse/check valve is fitted, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GFC two-unit family is available in sizes 200, 300, 400 and 600 with a choice of PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge style and scale, and a reverse/check valve option. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application 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.

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 (GFC60020AC1K) Is Used
Automotive paint-shop air supply
Feeds spray guns and air-fed respirator lines in a body shop: the filter stage strips water and 40 um particulate before the regulator holds a steady gun pressure and the lubricator mists oil for air-driven sanders and tools.
Packaging-line cylinder supply
Conditions the air feeding carton-sealing and case-packing cylinders on a packaging conveyor: clean, regulated pressure keeps stroke forces consistent while the oil mist extends cylinder and valve service life.
Machine-tool pneumatic clamping
Supplies fixture and clamp actuators on a CNC cell: the regulator pins the clamping pressure on the MPa gauge, the filter removes condensate and chips-laden debris from the shop air, and the lubricator conditions the air motor circuits.
Is the AirTAC GFC600-20 Combination Unit (GFC60020AC1K) the Right Set?
Start with the port and size: the 600 size with its PT3/4 connection suits the larger end of the GFC range, but always step the size against the flow your line actually needs rather than the pipe diameter alone. Choose the drain to match the site: automatic drain (this configuration) empties the bowl without daily attention, while manual and differential-pressure drains suit attended or lower-duty installations. Filtration is 40 um standard; specify the W code if the application needs 5 um. Gauge style and scale (MPa, psi or bar), the reverse/check valve, and PT versus G or NPT thread are all decodable options - PT is the standard thread, with G and NPT available as catalogue options.
Flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm the sizing against the datasheet before you order.
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 (GFC60020AC1K) FAQ
AirTAC publishes flow for the GFC family as curves rather than a single rated figure, so we do not quote a rated l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this exact configuration on request before you order.
The A in the code GFC60020AC1K specifies an automatic drain, which empties collected condensate from the filter bowl without daily manual attention - useful on unattended or high-condensate installations. The GFC family also offers manual and differential-pressure drains as decodable options if your maintenance routine suits those instead.
