The AirTAC GC600-20 AirTAC F.R.L. Combination, PT3/4, 5 um, Auto Drain 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 PT3/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20ALC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator mounted together, giving compressed-air filtration (water and particulate removal), pressure regulation and oil-mist lubrication in one assembly. This size 600 unit is ported PT3/4 (3/4 in, PT thread as standard; G and NPT are order options). The filter carries the 5 um element (grade code W) with an automatic drain, and at size 600 the bowl is aluminium alloy. The regulator is the low-pressure type, and the set is fitted with a round pressure gauge scaled in psi, a reverse/check valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale (embedded square gauge standard, external round gauge optional, MPa/psi/bar scales), reverse/check valve, low-pressure regulator type and thread. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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. 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.

|---|---|
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF600-20 filter, GR600-20 regulator and GL600-20 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.

Feeding spray guns and air tools at a paint booth: the 5 um element and water removal protect finish quality, the regulator holds a steady set pressure at the gun, and the lubricator mists oil to air tools on the same drop.
Supplying cylinders, grippers and diverters on a bottling or packaging conveyor: one three-unit set conditions the whole header - clean, regulated and lubricated air to every actuator on the line from a single 3/4 in take-off.
Conditioning air to pneumatic clamps and fixtures on a machine-shop CNC cell: filtered and regulated air holds consistent clamping force, the lubricator services the clamp cylinders, and the reverse/check valve helps hold the circuit if supply is interrupted.
Size and port step up together across 200, 300, 400 and 600, from 1/8 in to 1 in, so choose the size whose flow curve covers your demand - we can confirm the curve figures on request before you order. Drain choice: differential-pressure drain is the default, automatic drain (this unit) empties the bowl without operator attention, and manual drain suits installations on a scheduled drain routine. Filter grade is 40 um standard or 5 um with code W; this unit carries the 5 um element where finer particulate removal matters. Regulators come as standard or low-pressure type - this unit is low-pressure, and its exact adjustment range is not published, so confirm it with us. Gauges: embedded square gauge standard, external round gauge optional, in MPa, psi or bar scales; this unit has the round psi gauge. A reverse/check valve is fitted, a bracket is included, and thread is PT as standard with G (BSPP) and NPT available to order.
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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure and the demand of the equipment you are feeding, and we will confirm the sizing against the datasheet curves before you order.
The L code marks the low-pressure regulator type rather than the standard type. It is chosen where the circuit works at lower set pressures. The exact adjustment range for this low-pressure version is not published in the material we hold, so confirm the range with us; the standard regulator type is also available in the same size if your application calls for it.
