The AirTAC GC300C10AC2G AirTAC F.R.L. Combination, G3/8 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C10AC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This configuration is the 300 size with a G3/8 (BSPP) port. The filter section carries the standard 40 um element with an automatic drain, so collected condensate is expelled without manual attention. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) and is fitted with an external round gauge scaled in psi, so downstream pressure can be read and set directly at the unit. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls at this size are polycarbonate, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8" to 1", a choice of differential-pressure, automatic or manual drain, a 5 um (code W) filter element option, gauge scale in MPa, psi or bar, and PT, G or NPT thread as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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: GF300-C1 filter, GR300-C1 regulator and GL300-C1 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.

Installed at the point of use on a factory air drop, the unit removes water and particulate, holds a set working pressure for the tools and cylinders in the cell, and meters oil mist into the supply - one stack handling the three jobs a busy assembly cell needs.
On a packaging line where pneumatic cylinders stop, clamp and divert product, the combination conditions the supply feeding those valves: the 40 um element and automatic drain keep condensate out of the valve seats while the regulator pins the pressure the cylinders were sized for.
For an integrator building a pneumatic control panel on a special-purpose machine, a three-unit FRL at the panel inlet gives every downstream circuit filtered, regulated and lubricated air from one bracket-mounted stack, with the psi gauge readable on the panel face.
Start with the size and port: the GC range steps through sizes 200, 300, 400 and 600, each covering a larger port and flow band, so match the 300 size G3/8 port against the line feeding your cylinders and valves. Choose the drain for the filter bowl: automatic (this unit) suits unattended duty, manual suits periodic checks, and differential-pressure drain is the default. Pick the element grade: 40 um is standard for general plant air, 5 um (code W) where finer particulate removal is wanted. Select the gauge scale - this unit reads psi - and confirm the thread: PT is the standard, with G (BSPP) and NPT available as order options; this unit is supplied in G. 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 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request.
This unit has an automatic drain, which expels collected condensate on its own and suits installations that run unattended. The GC series also offers manual drain for periodically checked points and a differential-pressure drain as the default, so pick the type that matches how the site is actually maintained.
