AirTAC GFC300-15 Combination Unit (GFC30015F1K)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015F1K) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015F1K)
The AirTAC GFC series is a two-unit air preparation set: a filter regulator and a lubricator supplied as one matched pair. The filter regulator removes water and particulate from the compressed-air line and holds downstream pressure steady across a 0.15-0.9 MPa (20-130 psi) adjustment range, while the lubricator feeds a controlled oil mist to downstream tools and cylinders. This unit is the 300 size with a PT1/2 port, a differential-pressure drain on the filter bowl, a 40 um standard filter element, an embedded square gauge scaled in MPa and a reverse (check) valve fitted. Maximum working pressure is 1.0 MPa (145 psi), the service temperature range is -5 to 70 C (non-freezing), and the 300-size bowls are polycarbonate (PC).
This is a genuine AirTAC part sold by a distributor. The G series runs in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", and G (BSPP) and NPT threads, automatic and manual drains and 5 um W-grade elements are catalogue options to order. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your line 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 0.15 - 0.9 MPa (20 - 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 (GFC30015F1K) Is Used
CNC machining centre air supply
Mounted ahead of a CNC machining centre's air drop, the set strips condensed water and particulate from the shop supply, regulates pressure to the machine's valve stack and mists oil to the actuated tool-change and clamping circuits.
Packaging line carton sealer
On a carton-sealing conveyor line, the unit feeds clean, regulated and lubricated air to the cylinder-driven flap folders and tape heads, with the 1/2" port supplying a downstream actuator manifold.
Assembly line impact-wrench stations
At automotive assembly impact-wrench and nutrunner drops, the lubricator's oil mist services the vane motors through continuous shifts while the filter-regulator side holds a steady line pressure at each station.
Is the AirTAC GFC300-15 Combination Unit (GFC30015F1K) the Right Set?
Step between the 200, 300, 400 and 600 sizes to match port and flow demand; the 300 size carries a 1/2" port here. Choose the drain: differential-pressure (this model, standard), automatic for unattended draining, or manual for drain-on-demand. Filter grade is 40 um as standard; specify W for a 5 um element on finer-air duties. The embedded square gauge comes scaled in MPa here, with psi and bar scales orderable. Thread is PT as standard, with G (BSPP) and NPT orderable. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 (GFC30015F1K) FAQ
Flow for the G series is published as curves rather than a single rated figure, so there is no one number we can quote here. Send us your application details and we will confirm the sizing from the AirTAC datasheet on request.
K is the AirTAC catalogue code for a reverse (check) valve fitted to the regulator side of the set; units without the K are built without it. It is a build option on regulator-equipped G series units, and we can confirm the check-valve detail from the datasheet on request.
