The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MC1K) 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 PT1/2" ports, a 40 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GFC30015MC1K is a two-unit air preparation set: a 300-size filter regulator paired with a separate lubricator, giving filtration, pressure regulation and oil-mist lubrication from one 1/2 in PT connection. The K suffix means a reverse (check) valve is fitted, which helps hold downstream pressure if the supply side drops. This configuration has a manual drain, a 40 um standard filter element and an external round gauge scaled in MPa. It runs on compressed air only, up to 1.0 MPa (145 psi) and -5 to 70 C, and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Bowls on the 300 size are polycarbonate.
This is a genuine AirTAC part in the G-series 300 size. The family spans 200, 300, 400 and 600 sizes with 1/8 to 1 in ports, G (BSPP) and NPT thread options, automatic or differential-pressure drains, and a 5 um fine-filter option. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the datasheet for your application.

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 0.05 - 0.9 MPa (7 - 130 psi). 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: GFR300-15 filter regulator and GL300-15 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.

Preparation set ahead of a bank of directional control valves on a machine manifold, where the fitted check valve helps hold the regulated downstream pressure during supply-side dips.
Filtering, regulating and lubricating the air driving the film-clamp and sealing cylinders of a tray-sealing machine, with manual drain-down as part of the daily hygiene routine.
Conditioning air for clamp and ejector cylinders on a stamping press peripheral circuit, where the lubricator feeds the actuators and the check valve keeps clamps charged during brief supply losses.
This 300-size, 1/2 in PT set fits mid-range lines; move to 200 or 400/600 if your pipe and air demand differ. Drain is manual here, with automatic and differential-pressure as the other catalogue choices, and filtration is 40 um standard or 5 um with the W suffix. The K code adds the reverse (check) valve - choose it when you want downstream pressure held during supply dips. The external round gauge reads in MPa, with psi and bar scales available to order, and thread alternatives are G (BSPP) or NPT. Flow appears only as curves, 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 GFR300-15 filter regulator on its own.
AirTAC states flow for this series only as curves, not as a single rated figure, so we do not publish a number. Share your line pressure and air consumption and we will confirm the correct size and provide the datasheet on request.
It means a reverse (check) valve is fitted in the set. The valve helps keep downstream pressure from bleeding back if the upstream supply drops, which is useful on clamp and holding circuits. The rest of the decode is unchanged: 1/2 in PT ports, manual drain, 40 um element and an MPa round gauge.
