The AirTAC GC40015MLC2K AirTAC F.R.L. 1/2 in Low-Pressure Unit 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC40015MLC2K is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a low-pressure regulator holds the downstream set point, and a lubricator adds oil mist for downstream air tools and cylinders. This 400-size unit is fitted with a 1/2 in PT port, a manual drain on the filter bowl, a 40 um standard filter element, a round gauge reading in psi, a reverse/check valve, and a mounting bracket.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with a choice of ports, threads (PT standard, G and NPT as order options), drains, filter grades and gauge scales, so a configuration can be matched to most plant air drops. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing or any datasheet figure 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: 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.

A three-unit F.R.L. at the point of use on a factory air header: water and debris are dropped out, pressure is held at the low set point the cell runs at, and tool oil mist is supplied to the hand tools and actuators fed from that drop.
Feeding pneumatic cylinders and stop-gates on a packaging or conveyor line, where the filter keeps moisture out of the valves, the low-pressure regulator matches the actuation circuit's set point, and the lubricator extends cylinder and valve service life.
A wall- or bracket-mounted conditioning point in a maintenance shop: the 1/2 in PT connection serves impact wrenches and air ratchets, the manual drain is bled at shift checks, and the psi gauge lets technicians set and verify line pressure at a glance.
Start with the port and size: this unit is 400 size with a 1/2 in PT port, and the larger the size the larger the port and the greater the flow capacity. The filter bowl here drains manually, which suits installations where an operator can bleed accumulated water on a routine; automatic or differential-pressure drains are available if no one will be at the unit. The 40 um element is the standard grade; a 5 um element (code W) is offered where finer filtration is wanted. The low-pressure regulator type is chosen for circuits that run below the standard regulator's normal band - its exact adjustment range is not published, so confirm it with us. The round gauge reads in psi; MPa and bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
Because flow is published as curves and not a single rated number, send us your line size and demand and we will confirm sizing against the datasheet 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 GR400-15 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 number here. Tell us your line size and air demand and we will confirm the sizing against the datasheet on request before you order.
The M in the code selects a manual drain: an operator opens the filter bowl drain to remove accumulated water, which suits attended installations; automatic and differential-pressure drains are available as alternatives. The L selects the low-pressure regulator type, intended for circuits running below the standard band; its exact adjustment range is not published, so confirm the range with us for your set point.
