AirTAC GFC300-15 Combination Unit (GFC30015ALF1W)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015ALF1W) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015ALF1W)
GFC30015ALF1W is an AirTAC GFC two-unit air-treatment set: a filter-regulator paired with a separate lubricator, so it filters, regulates and lubricates compressed air in one order. This configuration is the 300 size with a PT1/2 port, built with the W 5 um filter element for finer particulate capture than the standard 40 um grade, an automatic drain that ejects collected condensate without manual attention, and the square pressure gauge with MPa scale. It is ordered in the L low-pressure regulator type. At size 300, the bowls on both the filter-regulator and the lubricator are PC (polycarbonate).
This is a genuine AirTAC part. The G-series family runs from size 200 through 600, with automatic, manual or differential-pressure drains, 40 um or 5 um elements, gauge choices and G (BSPP) or NPT thread options beyond the PT standard shown here. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GFC30015ALF1W) Is Used
CNC machine tool air supply
Feeds clean, regulated and lubricated air to the pneumatic clamps, tool-change cylinders and chip-ejection jets on a machining centre, with the 5 um element protecting tight-tolerance valve spools and the automatic drain handling condensate through long unattended shifts.
Packaging and cartoning machinery
Supplies the cylinder-and-valve circuits on a cartoner or case packer, where the lubricator maintains an oil mist for the sealing and forming cylinders, the regulator holds a steady working pressure for repeatable fold motions, and the square MPa gauge gives operators a clear setpoint reference.
Paint and finishing line air drops
Conditions the air at a spray-booth or finishing-line drop: the 5 um element removes water and particulate before the regulator sets delivery pressure, and the lubricator can be adjusted for air motors and cylinders downstream that benefit from mist lubrication.
Is the AirTAC GFC300-15 Combination Unit (GFC30015ALF1W) the Right Set?
Choose size by the port and flow step you need: 200, 300, 400 or 600, with 300 carrying the PT1/2 connection shown here and larger sizes moving up in port and flow capacity. Drain type is a real decision: automatic (as coded here) suits unattended duty, manual suits periodic checks, and differential-pressure is the default. This unit carries the W 5 um element; pick 40 um standard if finer filtration is not required. The F1 gauge code gives the square gauge with MPa scale, and the L code selects the low-pressure regulator type - confirm the exact adjustment ceiling for the low-pressure variant with us. Thread is PT as standard; G (BSPP) and NPT are catalogue options, and a mounting bracket can be specified. 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 (PT1/2" 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 0.15 - 0.9 MPa (20 - 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 (GFC30015ALF1W) FAQ
AirTAC publishes flow for the G series as performance curves, not as a single rated number, so we do not quote one here. Tell us your working pressure and required air consumption and we will confirm the sizing against the datasheet curves for the 300 size before you order.
The GFC pairs a filter-regulator with a lubricator in a two-piece arrangement, so you get filtration, regulation and lubrication with one fewer body in the line than a GC three-unit filter-plus-regulator-plus-lubricator set. This unit adds the W 5 um element, an automatic drain and the square MPa gauge; if 40 um filtration, a manual or differential-pressure drain, a different gauge scale, or G/NPT threads suit you better, those are all orderable options in the same 300 size.
