AirTAC GFC300-08 Combination Unit (GFC30008MC1K)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MC1K) 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 (GFC30008MC1K)
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator plus a lubricator supplied as a matched pair, so one order covers filtration, pressure regulation and oil-mist lubrication. This GFC30008MC1K is the size 300 set with PT1/4 ports, a manual drain on the filter-regulator bowl, the standard 40 um filter element, an external round gauge reading in MPa, and a built-in reverse (check) valve that holds downstream pressure when the upstream supply is removed. Maximum working pressure is 1.0 MPa (145 psi); with this manual-drain configuration the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); operating temperature is -5 to 70 C (non-freezing). The bowls on this size 300 set are polycarbonate (PC).
This is a genuine AirTAC part for the US market. The GFC family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in. to 1 in., ordered with your choice of drain type, 40 um or 5 um filtration, gauge and scale, reverse valve, and G (BSPP) or NPT threads instead of the PT standard. Flow for the G series is published as curves rather than one rated figure, so ask us and we will confirm the datasheet flow data 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 0.05 - 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 (GFC30008MC1K) Is Used
Paint line supply drop
Mounted at the drop feeding a spray booth's air logic panel, this set removes water and particulate, holds a steady regulated pressure for the spray valves, and meters oil mist to keep the actuators moving smoothly through a full shift.
Cartoning machine air supply
On a cartoner's pneumatic cylinders and glue-head valves, the filter-regulator cleans and stabilises the supply while the lubricator feeds the valve spools, and the check valve keeps the circuit charged during brief upstream interruptions.
CNC fixture clamping circuit
Feeding the clamp cylinders on a machining centre fixture, the unit delivers filtered, regulated air at a set pressure with a visible gauge reading, while lubrication protects the clamping valves over repeated cycles.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MC1K) the Right Set?
Size 300 with 1/4 in. PT ports is the mid step of the G-series range; match the port and size step to the flow your line needs, moving to size 400 (1/2 in. ports) if demand sits near the top of the size 300 curves. The manual drain here means an operator opens the bowl drain periodically - pick the automatic-drain version for unattended installations. Filtration is the standard 40 um element; add the W suffix for 5 um when downstream valves and cylinders need finer protection. The gauge is the external round type with an MPa scale (a psi scale is offered). Threads are PT as standard; order G (BSPP) or NPT to match your piping, and choose the bracket option if you panel-mount. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 (GFC30008MC1K) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated number, so no rated flow figure is quoted here. Tell us your required flow and working pressure and we will confirm the datasheet curves for this 1/4 in. set against your application on request.
K means a reverse (check) valve is fitted to the filter-regulator section: if the upstream supply is shut off, the valve holds pressure downstream so regulated circuits and cylinders do not dump back toward the supply. Sets without the K are ordered without this function.
