AirTAC GFC300-15 Combination Unit (GFC30015AF1W)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015AF1W) 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 (GFC30015AF1W)
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator plus a separate lubricator working as one matched pair, so compressed air is filtered, regulated and oil-mist lubricated before it reaches your cylinders, valves and tools. This GFC300-15AF1W is size 300 with PT1/2 ports, automatic drain on the filter bowl, the finer 5 um (W) filter element and an embedded square gauge reading in MPa. Maximum working pressure is 1.0 MPa (145 psi), the regulator adjusting range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C, non-freezing. At size 300, both bowls are polycarbonate (PC).
This is a genuine AirTAC part. The GFC series is offered in sizes 200, 300, 400 and 600, with 40 um standard or 5 um (W) filter elements, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT (standard), G (BSPP) or NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures and sizing for your application before ordering.

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 (GFC30015AF1W) Is Used
Laboratory automation actuators
Finely filtered, regulated and lubricated air drives the lift, grip and eject cylinders of automated lab handling equipment, where the 5 um element guards sensitive pilot valves.
Bottling line conveyor diverters
The set prepares supply air for the pusher and diverter cylinders that route bottles between conveyor lanes, with the automatic drain clearing condensate during continuous wet-climate operation.
CNC machining center clamping
Regulated, lubricated air at 5 um cleanliness actuates the pneumatic clamps and tool-change cylinders on a CNC machining center, protecting the machine's pilot-operated valves.
Is the AirTAC GFC300-15 Combination Unit (GFC30015AF1W) the Right Set?
Size 300 with 1/2 in. ports is the mid-range step of the GFC ladder: step down to 200/300 with 1/8-1/4 in. ports for compact machines, or up to 400/600 with 3/4-1 in. ports for higher-demand headers. The automatic drain expels collected condensate without operator attention; manual-drain versions open up the wider 0.05-0.9 MPa regulator range. The W code fits the 5 um element in place of the 40 um standard, a real choice when downstream valves or instruments need finer particulate removal. The square gauge is embedded and reads MPa; psi or bar scales and a round external gauge are orderable. PT is the standard thread, with G (BSPP) and NPT available as catalogue options; a mounting bracket is optional.
Because AirTAC publishes flow as performance curves rather than one rated number, we do not quote a flow figure here. Send us your air demand and we will confirm sizing from 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 (GFC30015AF1W) FAQ
AirTAC publishes flow for the G series as performance curves rather than a single rated figure, so we do not quote a number on this page. Send us your required flow and working pressure and we will confirm from the datasheet whether size 300 at 1/2 in. ports, with the 5 um element fitted, is correctly sized for your application.
The standard grade is 40 um, which suits general plant air for cylinders and air tools. The W code changes the element to 5 um, a sensible choice when the same supply feeds pilot valves, precision actuators or instrumentation that tolerate less particulate. Note that finer filtration loads faster, so check the drain arrangement and element service with us against your duty cycle.
