The AirTAC GC40015LF2K AirTAC F.R.L. Combination PT1/2 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This size 400 unit is built with 1/2 in PT ports, a 40 um filter element and a differential-pressure drain on the filter bowl, so water and particulate drop out as flow passes through. The regulator is the low-pressure type and carries an embedded square gauge scaled in psi, and a reverse/check valve is fitted to hold downstream conditions. The lubricator mists oil into the air line to feed downstream pneumatic tools, cylinders and valves. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowls on the 400 size are polycarbonate (PC).
This is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options include manual or automatic drains, a 5 um (W) filter element, alternate gauge scales (MPa/psi/bar), G (BSPP) or NPT threads and external round gauges. Flow is published as curves rather than a single rated figure, so ask us to confirm the sizing or any datasheet figure against 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: GF400-15 filter, GR400-15 regulator and GL400-15 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-assisted applicators on a finishing line, where the filter strips water and particulate, the low-pressure regulator holds a gentle set point and the lubricator keeps gun triggers and air motors running smoothly.
Supplying the cylinders and vacuum-assist circuits on a cartoner or case packer, with conditioned, regulated and lubricated air at a 1/2 in connection and a check valve holding the circuit when supply dips.
A central conditioning point for nutrunners, impact drivers and air cylinders at an assembly cell, delivering filtered, regulated, oil-misted air so tools and actuators at the bench receive consistent supply.
Start with the port step: size 400 with 1/2 in PT ports sits in the upper-middle of the GC range (200/300/400/600), so step up or down according to the air demand of the line - the published flow curves, not a single rating, are the reference. This unit is the low-pressure regulator type, so confirm the working band you need with us; the exact low-pressure range is not published in the standard table. The filter carries the standard 40 um element (5 um is available as the W option) with a differential-pressure drain as built; automatic or manual drains can be specified instead. The square gauge is scaled in psi here, with MPa or bar scales orderable, and the reverse/check valve is already fitted. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Ask us to confirm sizing against your application before ordering.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the correct sizing from the datasheet curves on request before you order.
The L in GC40015LF2K marks the low-pressure regulator type rather than the standard one, intended for applications that work at lower set points. The exact adjustment range for the low-pressure type is not published in the standard table, so confirm your required band with us and we will verify suitability from the datasheet. The standard GC regulation figures apply only to non-L versions.
