AirTAC GFC600-25 Combination Unit (GFC60025C1K)
The AirTAC AirTAC GFC600-25 Combination Unit (GFC60025C1K) 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 (GFC60025C1K)
The AirTAC GFC60025C1K is a genuine two-unit air-treatment set for compressed air only: a filter regulator plus a separate lubricator, with a reverse (check) valve fitted as denoted by the K in the code. This size 600 configuration is built around 1 in. PT ports, a 40 um standard filter element, a differential-pressure drain on the filter bowl, and an external round pressure gauge scaled in MPa. At 600 size the filter bowl is aluminium alloy.
Maximum working (inlet) pressure is 1.0 MPa (145 psi). With the differential-pressure drain fitted, the regulator adjusts from 0.15 to 0.9 MPa (20 to 130 psi), and the operating temperature range is -5 to 70 C (non-freezing). AirTAC offers this series in 200, 300, 400 and 600 sizes, with G (BSPP) or NPT thread options, automatic or manual drains, a 5 um element and gauge choices. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

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 (GFC60025C1K) Is Used
Pneumatic press station supply
A workholding press fed from a 1 in. branch: the set filters, regulates and lubricates, while the fitted check valve sits in the circuit as specified for the station design.
Automotive plant air drops
Point-of-use treatment at a 1 in. main drop feeding impact wrenches and air ratchets: water and scale are stripped out, downstream pressure is held steady, and the lubricator feeds the tool line.
Bottling line actuator feed
A packaging line's valve manifold and cylinder bank drawing from one treatment point: clean, pressure-controlled air plus lubrication for the filler and capper pneumatics.
Is the AirTAC GFC600-25 Combination Unit (GFC60025C1K) the Right Set?
Size 600 is the largest step in the G series, with 1 in. PT ports; step down to 400, 300 or 200 sizes with smaller ports if your demand is lower. Drain types are differential-pressure (this unit), automatic (A) or manual (M); the drain choice also sets the regulation window, with manual-drain versions allowing adjustment down to 0.05 MPa. The 40 um element is standard and a 5 um (W) element is available for finer filtration. The K code means a reverse (check) valve is fitted; the same unit is available without it. Thread is PT as the standard, with G (BSPP) and NPT as catalogue options, and the C1 code means an external round gauge scaled in MPa. Flow is published as curves, not a single rated figure, so ask us to confirm sizing 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 (GFC60025C1K) FAQ
AirTAC publishes flow for the G series as curves rather than a single rated number, so we do not quote a fixed figure here. Tell us your line pressure and air demand and we will confirm the relevant flow figures from the datasheet on request.
It means a reverse (check) valve is fitted in this unit; the equivalent model without the K, GFC60025C1, is supplied without one. Everything else in the code decodes the same: two-unit FRL set, size 600, 1 in. PT ports, 40 um element, differential-pressure drain and a round MPa gauge.
