AirTAC GFC600-20 Combination Unit (GFC60020AF1WK)
The AirTAC AirTAC GFC600-20 Combination Unit (GFC60020AF1WK) 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 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC600-20 Combination Unit (GFC60020AF1WK)
GFC60020AF1WK is an AirTAC GFC two-unit set for compressed air: a 600-size filter regulator paired with a lubricator, so filtration, pressure regulation and oil-mist lubrication arrive in one order. This version combines the W 5 um filter element with a fitted reverse-flow (check) valve, and also carries a PT3/4 port, an automatic drain on the filter bowl, and an embedded square pressure gauge with MPa scale.
This is a genuine AirTAC part. The G series is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in. to 1 in. and PT, G(BSPP) or NPT threads; 600-size bowls are aluminium alloy, working pressure is up to 1.0 MPa (145 psi), temperature range is -5 to 70 C, and the regulator adjusts 0.15-0.9 MPa (20-130 psi) on this automatic-drain version. Rated flow is published as curves rather than a single figure; ask us and we will confirm the datasheet figures for your application.

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 (GFC60020AF1WK)
| 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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 (GFC60020AF1WK) Is Used
Mobile repair carts with pneumatic tools
Mounted on a maintenance cart to feed grinders and drills; the check valve blocks air from back-feeding through the set from the tool side, and the 5 um element suits the tool valves downstream.
Pneumatic clamping on CNC machining fixtures
Regulated and lubricated air for workholding clamps on a machining centre, with 5 um filtration protecting the clamp valve stack.
Air-operated valves on a dosing skid
Supplies actuation air to diaphragm valves on a chemical dosing skid; the lubricator conditions the actuator air and the check valve stops reverse flow through the set.
Is the AirTAC GFC600-20 Combination Unit (GFC60020AF1WK) the Right Set?
This is the 600-size, 3/4 in. PT configuration for circuits with heavier air demand, chosen where you also want the W 5 um element and the K check valve in the same set. The A code gives an automatic drain, so the bowl clears itself, with the 0.15-0.9 MPa (20-130 psi) adjustment range that applies to this drain type. F1 is the embedded square gauge on an MPa scale; psi and bar scales are catalogue options. PT is the standard thread, with G and NPT available to order.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your pressure and demand 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 (GFC60020AF1WK) FAQ
AirTAC publishes G-series flow as performance curves, not a single rated figure, so we do not quote a number here. Give us your working pressure and air demand and we will confirm the datasheet curve for this 600-size, PT3/4 set before you order.
A in the code means the filter bowl drains automatically, so no operator action is needed; an M code gives a manual drain that is emptied by hand. Drain choice also sets the regulator adjustment range: automatic and differential-pressure drain units adjust 0.15-0.9 MPa (20-130 psi), while manual-drain versions start lower at 0.05 MPa.
