Airtac GFC Combination Unit GFC300C15NW
The AirTAC GFC Combination Unit GFC300C15NW 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC300C15NW
GFC is the AirTAC two-unit air preparation set: a filter regulator and a lubricator supplied as one matched pair, covering water and particle removal, pressure regulation and oil-mist lubrication from a single part number. This 300-size set is piped at 1/2 in on the standard PT thread and steps up to the 5 um filtering element (the W code) for air that feeds finer equipment, while keeping the default differential-pressure drain and no reverse valve. The regulator adjusts from 0.15-0.9 MPa (20-130 psi), maximum working pressure is 1.0 MPa (145 psi), the bowls are PC (polycarbonate) at this size, the mounting bracket is included, and no gauge is specified on this code.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT to order, 40 um standard or 5 um filtering, differential-pressure, automatic or manual drains, and -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures for your application 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-C1 filter regulator and GL300-C1 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 GFC Combination Unit GFC300C15NW Is Used
Furniture spray-finishing line
Feeds the spray guns on a furniture finishing line, where the 5 um element is chosen for the cleaner air the gun side of the set requires.
Instrument test benches
Conditions the supply to pneumatic test benches in a quality lab, with the lubricator oil-misting the air motors and the finer element suiting the instrumentation downstream.
Electronics assembly benches
Supplies the pick-and-place and clamping air at electronics assembly benches, where the small control valves in use are matched to the 5 um grade.
Is the Airtac GFC Combination Unit GFC300C15NW the Right Set?
The only change from the base GFC300C15N is the W in the code: the 5 um element instead of the 40 um standard, for lines feeding finer pilot valves, spray equipment or instruments. Size 300 with a 1/2 in PT port is the step for lines beyond 1/4 or 3/8 in piping; go to size 400 (3/4 in) or 600 (1 in) for larger demand. The drain here is the default differential-pressure type; the manual (M) variant widens the regulator range to 0.05-0.9 MPa (7-130 psi) from the 0.15-0.9 MPa (20-130 psi) on this code, and automatic (A) is also available. No gauge is specified; an embedded square or external round gauge can be ordered instead. Thread is PT as standard with G (BSPP) and NPT to order, and the bracket is included. 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 (See datasheet 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C15NW FAQ
G-series flow is published as curves rather than a single rated figure, so we do not state a number here. Give us your line pressure and expected air demand and we will confirm the flow and datasheet figures for this exact set on request.
The 40 um element is the standard choice for general cylinder and valve service; the 5 um element on this model is for air feeding finer equipment such as pilot valves, spray equipment and instruments. It is a filtration-grade choice only - for sizing, the flow and datasheet figures are confirmed on request because flow is published as curves, not a single rating.
