AirTAC GFC300-08 Combination Unit (GFC30008MC1)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MC1) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008MC1)
GFC30008MC1 is an AirTAC G-series two-unit air preparation set: a filter regulator and a lubricator supplied as a pair for filtration, pressure regulation and oil-mist lubrication on a 1/4 in PT line. This 300-size configuration is the standard regulator type with the 40 um filter element and a manual drain (M) on the filter bowl; the C1 code adds an external round gauge with an MPa scale. Maximum working pressure is 1.0 MPa (145 psi), and for the manual-drain version the regulator setting range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The G-series spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scale, and PT, G(BSPP) or NPT threads. Operating temperature is -5 to 70 C (non-freezing), and the bowls on this 300-size set are polycarbonate. AirTAC publishes flow as curves, not a single rated figure, so we confirm the datasheet and sizing 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: GFR300-08 filter regulator and GL300-08 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
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.

Where the AirTAC GFC300-08 Combination Unit (GFC30008MC1) Is Used
Maintenance workshop drops
Feeds the repair-bay outlets where impact wrenches, air hammers and blow guns are used, with the manual drain letting the operator bleed the bowl at the start of each shift and the MPa gauge showing set pressure at a glance.
Textile machine actuation
Prepares air for the dobbies, jets and cylinder drives on weaving and knitting machines, where the regulator holds the set pressure the machine builder specifies and the lubricator protects high-cycle pneumatics.
Trailer and dock equipment
Conditions air for dock levellers, curtain tensioners and tail-lift test rigs, where the round gauge gives a clear pressure reading for operators and the manual drain suits supervised, periodic-use equipment.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MC1) the Right Set?
Choose the size and port for your line - 300 gives a 1/4 in port here, and other sizes step the port and flow capacity up or down. The M in this code selects a manual drain, which lets the regulator cover the wider 0.05-0.9 MPa (7-130 psi) setting range; automatic or the default differential-pressure drain are the hands-off alternatives. The standard 40 um element is fitted here, with 5 um (W) as the finer option. The C1 code specifies an external round gauge on an MPa scale; an embedded square gauge or psi/bar scales are the other gauge choices. PT is the standard thread, with G(BSPP) and NPT as catalogue options.
Flow is published as curves rather than a single rating, so ask us to confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.05 - 0.9 MPa (7 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the set above freezing (-5 to +70 °C, unfreeze).
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.
AirTAC GFC300-08 Combination Unit (GFC30008MC1) FAQ
No single rated flow number is published for this set - AirTAC publishes G-series flow as characteristic curves. We do not quote a figure here, but if you send us your line pressure and consumption we will confirm the sizing and the curve data from the datasheet on request.
The M code selects the manual drain: someone bleeds the bowl by hand at intervals. The benefit is the wider regulator setting range of 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for the differential-pressure and automatic drain versions. If nobody is on site to drain it, choose an A-coded or default differential-drain model instead.
