AirTAC GFC300-15 Combination Unit (GFC30015F3)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015F3) 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 (GFC30015F3)
The AirTAC GFC30015F3 is a two-unit compressed-air treatment set: a filter regulator mounted with a separate lubricator, so it filters water and particulate, regulates downstream pressure and adds oil mist for air tools and cylinders in one package. This size 300 configuration carries a PT1/2 in. port, the standard 40 um filter element, a differential-pressure drain on the filter bowl, and an embedded square pressure gauge scaled in bar. Maximum working pressure is 1.0 MPa (145 psi), with a regulator adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part from the G-series, which spans sizes 200, 300, 400 and 600 with 1/8 to 1 in. ports, G (BSPP) or NPT thread options, automatic, manual or differential-pressure drains and 5 um or 40 um filtration. Flow figures for this model are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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 0.15 - 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 (GFC30015F3) Is Used
Pneumatic press feed
Feeding a bench or C-frame pneumatic press: the filter regulator holds a stable set pressure for consistent forming force while the lubricator oils the press cylinders and valves on every stroke.
Packaging line air supply
Conditioning the air supply to a carton-sealing or wrapping line, where clean, regulated pressure keeps clamp and pusher cylinders repeatable and the lubricator protects them across long shifts.
Assembly-shop tool air
Supplying impact wrenches, nut runners and air ratchets at a maintenance workstation: the set removes water and scale, sets tool pressure, and carries oil mist to keep the tools running.
Is the AirTAC GFC300-15 Combination Unit (GFC30015F3) the Right Set?
Size 300 with a PT1/2 in. port is a mid-range step in the G-series; step up to size 400 or 600 or down to 200 depending on the flow your line needs. The differential-pressure drain bleeds condensate automatically when the pressure differential is high enough - choose the M (manual) suffix if you want operator-controlled draining, or A for fully automatic. The standard 40 um element suits general plant air; add the W suffix for a 5 um element ahead of finer valves. The square gauge here reads in bar; psi or MPa scales and the external round gauge are catalogue options. PT thread is standard, with G (BSPP) and NPT available to order, and a bracket is included.
Flow is published as curves, not a single rated figure, 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 (GFC30015F3) FAQ
AirTAC publishes flow for the G-series as characteristic curves, not as a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Tell us your working pressure and required flow and we will confirm sizing against the datasheet on request before you order.
The F3 suffix is the gauge option: an embedded square pressure gauge with a bar scale. Psi (F2) or MPa (F1) scales are available as options, and the standard code without a gauge suffix also exists. The thread on this model is PT as standard, with G (BSPP) and NPT offered as catalogue alternatives.
