AirTAC GFC300-15 Combination Unit (GFC30015MF1W)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MF1W) 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 5 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015MF1W)
The AirTAC GFC is a two-unit air-treatment set: a filter regulator and a lubricator mounted together, so one assembly filters, regulates and oil-mist lubricates the compressed air line. This 300-size configuration has a PT1/2 port, a manual drain on the filter bowl, a fine 5 um filter element, and an embedded square pressure gauge reading in MPa. The manual drain means an operator opens the drain valve to expel collected water, which also allows the regulator to be set as low as 0.05 MPa (7 psi).
This is a genuine AirTAC part. The GFC series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, and G or NPT thread options. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Because flow is published as curves rather than a single rating, we confirm flow and datasheet figures on request before you order.

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.
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 GFC300-15 Combination Unit (GFC30015MF1W) Is Used
CNC machining centre air supply
Filtering, regulating and lubricating the shop-air drop that feeds tool-changer cylinders and clamping fixtures on a CNC mill, with fine 5 um filtration protecting tight-tolerance valves.
Packaging machine actuation
Conditioning the air that drives carton-forming and sealing cylinders on a packaging line, where the square MPa gauge lets operators verify set pressure at a glance and the lubricator mists the actuators.
Assembly-line pneumatic tools
A treated-air station on an assembly line feeding impact drivers and air ratchets: regulated pressure for consistent torque and oil mist to keep the tools lubricated through a shift.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MF1W) the Right Set?
Size and port set the capacity: the 300 size with a 1/2 in port suits medium-duty plant air drops; step up to 400 or 600 for larger lines. The manual drain suits attended installations where someone can bleed the bowl; choose automatic or differential-pressure drain codes for unattended duty. The 5 um (W) element is the finer choice over the 40 um standard when downstream equipment needs cleaner air. Gauge: embedded square with MPa scale here; round gauges and psi/bar scales are options. Thread is PT as standard - order G (BSPP) or T (NPT) variants if your pipework needs them.
Flow for this set is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GFR300-15 filter regulator on its own.
AirTAC GFC300-15 Combination Unit (GFC30015MF1W) FAQ
AirTAC publishes flow for this set as performance curves rather than a single rated figure, so no single number can honestly be quoted. Send us your line pressure and demand and we will confirm the sizing from the datasheet on request.
The M in the code means the filter bowl is drained by hand when pressure is relieved; automatic (A) or differential-pressure drain versions exist for unattended duty. The W code upgrades filtration from the 40 um standard element to a 5 um element for cleaner air downstream. The manual drain also allows regulator settings down to 0.05 MPa (7 psi).
