The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MF1K) 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).
GFC30015MF1K is an AirTAC G-series two-unit F.R.L. set pairing a filter-regulator in one body with a separate lubricator for combined filtration, regulation and oil-mist lubrication. This 300-size set has a 1/2 in PT port, a manual drain on the polycarbonate filter bowl, the standard 40 um element, a square embedded gauge in MPa, and the K suffix fitting a reverse (check) valve to stop backflow through the unit. Maximum working pressure is 1.0 MPa (145 psi); the manual-drain regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFC family is available in 200/300/400/600 sizes with ports from 1/8 in to 1 in, 40 um standard or 5 um W filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and the reverse-valve option; G and NPT threads are catalogue options besides the standard PT. Flow is published as curves, not a single rating, so we confirm 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. 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.

Air preparation for the diverter and pusher cylinders on a distribution-center sortation conveyor, where the check valve stops the energized circuit from back-feeding through the set.
Filtered, regulated, lubricated air to the part-ejection and clamp circuits of a metal stamping press cell, read and set on the MPa-scale square gauge.
Lubricated air supply at heavy-equipment service bays feeding pneumatic impact tools and chassis work, with the regulator set to the shop's standard working pressure.
Use the 300 size with 1/2 in PT port on 1/2 in distribution at mid-range duty; step to 400 or 600 for bigger circuits or 200 for 1/8-1/4 in lines. Manual drain (M) delivers the wider 0.05-0.9 MPa (7-130 psi) regulation range but needs a hand-drain routine; choose automatic drain where maintenance rounds are impractical. The 40 um element is the standard general-line grade, with 5 um (W) as the finer alternative. The square MPa gauge is the embedded type; a round external gauge or psi/bar scales can be ordered instead. Specify the K reverse (check) valve exactly where backflow through the set must be blocked, and omit it elsewhere. G or NPT threads can be ordered against standard PT, and the temperature range is -5 to 70 C (non-freezing). 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.
Flow for G-series units is published as characteristic curves rather than a single rated figure, so we do not state one l/min or SCFM number. Give us your line conditions and we will confirm the sizing against the GFC300 datasheet curves on request before you order.
K fits a reverse (check) valve, so downstream air cannot flow back through the set when the upstream supply is vented or drops. The same unit without K is GFC30015MF1. Specify K only on circuits where that backflow blocking is actually needed.
