AirTAC GFC600-20 Combination Unit (GFC60020MF1K)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020MF1K) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC600-20 Combination Unit (GFC60020MF1K)
The GFC is AirTAC's two-unit air preparation set: a filter regulator plus a lubricator, so filtering, regulating and oil-mist lubricating are handled in one mounting. This 600-size unit has PT3/4 ports, a manual drain on the filter bowl, the standard 40 um element, an embedded square gauge in MPa, and a reverse (check) valve fitted as coded by the trailing K. The 600 frame uses an aluminium alloy bowl on the filter section.
This is a genuine AirTAC part for compressed air, rated to 1.0 MPa (145 psi) inlet and -5 to 70 C (non-freezing); as a manual-drain unit the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). The same set is available in 200, 300 and 400 sizes, with the finer 5 um element, automatic or differential drains, a round external gauge, and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet 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 0.05 - 0.9 MPa (7 - 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 (GFC60020MF1K)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 (GFC60020MF1K) Is Used
Injection moulding machine core-pull circuits
Core-pull and ejector circuits on an injection moulding machine need regulated, lubricated air that stays put between strokes - the fitted check valve holds the regulated side while the set conditions the 3/4-inch machine supply.
Bottling plant conveyor gate and stopper actuators
Conveyor gates, stoppers and pushers on a bottling line cycle continuously; this two-unit set filters, regulates and lubricates the branch supply, with the check valve preventing backflow through the preparation point.
Shipyard air-tool rings main
A shipyard's deck-level tool ring running grinders and drills from a 3/4-inch branch benefits from the 40 um protection, set regulation on the square gauge, oil mist for the tools, and the check valve holding pressure at the ring.
Is the AirTAC GFC600-20 Combination Unit (GFC60020MF1K) the Right Set?
Pick the K version when you want the reverse (check) valve fitted at the factory rather than added downstream. This is the 600 frame on a 3/4-inch PT port - verify against the flow curves whether a 300 or 400 unit would serve your demand, since published flow is in curve form, not a single figure. The manual drain suits units that are walked past on a routine; automatic (A) or the differential-pressure default are the alternatives. The 40 um element is the standard grade; choose the 5 um W version for finer filtration. The square MPa gauge is embedded for a compact footprint; round gauges and psi or bar scales exist in the catalogue. PT is the standard thread, with G (BSPP) and NPT available to order. Ask us to confirm sizing 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 0.05 - 0.9 MPa (7 - 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 (GFC60020MF1K) FAQ
No single rated figure exists to quote - AirTAC publishes G-series flow as curves. Send us your working pressure and consumption and we will confirm the sizing from the datasheet on request before you order.
The K suffix means a reverse (check) valve is fitted, useful when downstream pressure should be held against backflow. If you do not need that, the plain GFC60020MF1 is the identical two-unit set without the check valve; drain, filter grade, gauge and thread options are the same in both codes.
