The AirTAC GC40010LC2GK AirTAC F.R.L. Combination, G3/8, 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40010LC2GK is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set, giving filtered, regulated and lubricated compressed air from a single supply point. This size 400 unit is configured with a G3/8 port, a 40 um filter element and a differential-pressure drain on the filter bowl, a low-pressure type regulator, a round gauge reading in psi, a reverse/check valve, and a mounting bracket. The PC (polycarbonate) bowls let you see condensate and oil level at a glance. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and thread options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and flow figures for your application 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. 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: GF400-10 filter, GR400-10 regulator and GL400-10 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.

Feeds filtered, regulated and lubricated air to the impact wrenches, air ratchets and clamping fixtures at a vehicle assembly cell, with the check valve holding the set circuit if the main supply dips.
Supplies the cylinder-actuated pushers, diverters and case sealers along a packaging conveyor, where the lubricator keeps seal and valve life up through continuous shift running.
Conditions the shop-air feed to a CNC machining centre's tool changer, clamping and air-blast circuits, protecting downstream valves from water and particulate carryover.
Start with the size and port: GC400 with a G3/8 port sits in the middle of the range - step up to GC600 for larger air demand or down to GC300/GC200 for compact circuits, always matching the port step to the flow your line needs. The drain on the filter bowl is differential-pressure here (it bleeds condensate as the pressure differential rises); automatic (code A) and manual (code M) drains are the other catalogue choices. The 40 um element is the standard grade; specify W for the 5 um grade where finer particulate removal is required. The round gauge fitted to this unit reads in psi; square embedded gauges and MPa or bar scales are the alternative options. Thread is G (BSPP) on this code; PT is the standard series thread and NPT is also an order option. The low-pressure type regulator (code L) is intended for circuits that work below the standard setting range - the exact regulation range for the low-pressure version is not published, so confirm it with us. Flow is published as curves, not a single rated figure, so send us your air demand and we will confirm sizing against the application before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number here. Tell us your air demand and operating pressure and we will confirm the flow curve and sizing from the datasheet on request before you order.
The L marks the low-pressure type regulator, intended for circuits that run below the standard setting range; the exact regulation range for the low-pressure version is not published, so confirm it with us. The filter bowl on this unit uses the differential-pressure drain (the series default); automatic and manual drains are available as alternative codes.
