AirTAC GFC300-10 Combination Unit (GFC30010AC1W)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AC1W) 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 PT3/8" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010AC1W)
GFC30010AC1W is a two-piece AirTAC G-series set combining a filter regulator and a lubricator, with the W suffix specifying the finer 5 um filter element instead of the 40 um standard. This size-300 unit has PT3/8 ports, an automatic drain (A) on the filter bowl and an external round gauge scaled in MPa. With the automatic drain, the regulator adjusts 0.15-0.9 MPa (20-130 psi), and the lubricator adds oil mist for downstream air tools and cylinders.
It is a genuine AirTAC part for compressed air, rated to a maximum working pressure of 1.0 MPa (145 psi) and -5 to 70 C (non-freezing). The GFC two-unit family covers sizes 200, 300, 400 and 600 in 1/8 to 1 inch ports with drain, filter-grade, gauge, thread and check-valve options. Flow figures are published as curves, so we confirm datasheet numbers 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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010AC1W) Is Used
Paint-line spray guns
Prepares air for spray guns on a finishing line; the 5 um element provides finer filtration than the standard grade ahead of the gun and its air cap.
Dispensing-valve station
Feeds the metering and dispensing valves on an electronics assembly cell, where the finer 5 um grade and the automatic drain reduce particulate and moisture reaching the valves.
Vacuum ejector supply
Supplies the compressed-air side of vacuum ejectors on a packaging machine; regulation steadies the ejector supply while the lubricator section serves adjacent air cylinders.
Is the AirTAC GFC300-10 Combination Unit (GFC30010AC1W) the Right Set?
Choose the W (5 um) element when the downstream equipment calls for finer filtration than the 40 um standard; regulation, drain and lubrication behaviour are unchanged. Size 300 with PT3/8 ports is one step in the family's range of 200, 300, 400 and 600 with 1/8 to 1 inch ports - match the step to the machine's air demand, and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
The A suffix selects the automatic drain, with manual (M) and differential-pressure drains as the alternatives; note the regulator range is 0.15-0.9 MPa (20-130 psi) with automatic or differential drain and 0.05-0.9 MPa (7-130 psi) with manual. The C1 gauge reads in MPa, with psi and bar scales available. PT is the standard thread; G (BSPP) and NPT are orderable options.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010AC1W) FAQ
Flow for the G series is published as performance curves, not as a single rated figure, so we cannot quote one rated number. Give us your application's air demand and working pressure and we will confirm the sizing against the datasheet on request.
Pick the W version when the equipment downstream of the set is sensitive to finer particulate - for example precision valves, dispensing equipment or spray guns. Everything else matches the standard set: PT3/8 ports, automatic drain, external MPa round gauge and a 0.15-0.9 MPa (20-130 psi) regulation range.
