The AirTAC GC600-25 AirTAC F.R.L. Combination, G1 Port, Low-Pressure is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-25 is a three-piece AirTAC F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation unit. In use, compressed air first passes through the filter, which removes water and particulate down to 5 um (the W filter grade), then through the low-pressure-type regulator, and finally through the lubricator, which adds oil mist for downstream air tools and cylinders. This 600-size unit has a 1 inch port with G (BSPP) thread, a differential-pressure drain on the filter bowl, a fitted square gauge reading in psi, and a reverse/check valve fitted. The filter bowl on size 600 is aluminium alloy.
This is a genuine AirTAC part in the largest of the G-series sizes (200/300/400/600), where the 600 size carries the largest port and the highest flow capacity of the range. Across the series you can choose port sizes and PT/G/NPT threads, drain types, 40 um or 5 um filtration, gauge type and scale, and low-pressure or standard regulators. Flow is published as curves rather than a single rated figure, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three 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. Constituent units, orderable separately as spares: GF600-25 filter, GR600-25 regulator and GL600-25 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Point-of-use preparation on a 1 inch branch feeding air impact wrenches and nutrunners: 5 um filtration for clean air, regulation at low working pressure, and oil mist to keep tool motors lubricated through a full shift.
Conditioning the air line ahead of spray booths and paint pumps, where water and fine particulate must be stripped out before the regulator and the lubricator is set to feed only the downstream air motors, not the finish.
Feeding pneumatic cylinders and diverters on a packaging conveyor: the filter protects the valves, the low-pressure regulator holds a gentle setpoint for delicate product handling, and the lubricator services the air cylinders.
Size 600 with a 1 inch (G1) port sits at the top of the G-series range; step down to 200/300/400 if your line flow is smaller, since the right size is set by required flow, not by pipe size alone. The 5 um (W) element suits applications needing finer particulate removal than the 40 um standard element. The low-pressure-type regulator is the correct choice where the working circuit must run at reduced pressure; note that the exact adjustment range for the low-pressure type is not published in the material we hold, so confirm the range with us against your setpoint. The differential-pressure drain bleeds the bowl automatically as pressure drops across the element; automatic or manual drains are available on other variants. The fitted square gauge reads in psi; an external round gauge with MPa, psi or bar scale is optional. G (BSPP) thread is specified here; PT is the standard thread and NPT is also an order option. A mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR600-25 regulator with a GF600-25 filter on that branch.
AirTAC publishes flow for the GC600 series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet curves before you order.
The L in the code GC60025LF2WGK decodes to the low-pressure-type regulator, intended for circuits that run at reduced working pressure; the exact adjustment range for the low-pressure type is not published in the material we hold, so confirm your setpoint with us. The W decodes to the 5 um filter element, one grade finer than the 40 um standard element. Both are factory build options on the GC600, not modifications.
