The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008ALC1) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC30008ALC1 is a genuine AirTAC GFC two-unit air-preparation set for compressed air: a filter-regulator that strips water and particulate and holds downstream pressure, plus a separate lubricator that meters oil mist to downstream equipment. This 300-size set has PT1/4 ports, an automatic drain, the standard 40 um element and the low-pressure regulator type, intended for circuits that run at reduced set-points. It is fitted with the external round pressure gauge scaled in MPa.
You are buying a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with PT, G (BSPP) or NPT threads, 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and square or round gauges in MPa, psi or bar scales. The filter-regulator bowl on this 300 size is polycarbonate. Inlet pressure is rated to 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm sizing, the low-pressure set-point band and datasheet figures 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 set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Regulates and lubricates air for low-pressure clamp cylinders on a machining fixture, protecting the workpiece while keeping the circuit supplied with clean, oiled air.
Prepares air for the doffing and threading cylinders on a spinning frame, where the low-pressure type matches circuits run below standard plant pressure.
Supplies filtered, lubricated air to diaphragm actuators on a water-treatment valve skid, with the automatic drain clearing condensate from the bowl.
This 300-size set with 1/4 in ports sits in the middle of the G series range of 200, 300, 400 and 600 frames - pick the size that matches your port and flow requirement. The key choice on this code is the low-pressure regulator type: choose it when your circuit runs at a reduced set-point, or the standard type when full-range regulation is needed; we confirm the exact set-point band from the datasheet on request. The automatic drain handles condensate unattended, and the 40 um element suits general plant air. The round gauge is scaled in MPa; square or psi/bar scales are orderable. PT thread is standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not a single rating, so 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
We do not quote a single flow number because AirTAC publishes flow for this series as curves rather than a rated figure. Tell us your line pressure, port size and downstream demand and we will confirm the flow curve and datasheet figures for this model on request.
The L in GFC30008ALC1 decodes as the low-pressure regulator type, chosen for circuits that operate at reduced set-points; the standard type covers the full regulation range. Both share the same filtering, drain and lubrication functions, and we confirm the exact set-point band from the datasheet on request.
