AirTAC GFC300-08 Combination Unit (GFC30008AF1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AF1W) 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 PT1/4" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008AF1W)
The AirTAC GFC30008AF1W is a two-unit air-treatment set for compressed air: a filter regulator plus a separate lubricator, giving filtration, regulation and oil-mist lubrication at one station. The W in the code selects the finer 5 um filter element instead of the 40 um standard, for cleaner air ahead of sensitive valves and instruments. This configuration is size 300 with a 1/4 inch PT port, an automatic bowl drain and the embedded square gauge scaled in MPa; the 300-size bowls are polycarbonate (PC).
This is a genuine AirTAC part from the G series, available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and PT, G (BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi), the regulator adjusts 0.15-0.9 MPa (20-130 psi) on this automatic-drain version, and operating temperature is -5 to 70 C, non-freezing. Flow is published as curves, not a single rating, so we confirm the datasheet 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: GFR300-08 filter regulator and GL300-08 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 GFC300-08 Combination Unit (GFC30008AF1W) Is Used
Lab pneumatic sample handling
Conditions the air feeding sample-transfer cylinders and pneumatic grippers in a laboratory automation line, where the 5 um element keeps fine particulate away from small-bore valves and precision actuators.
Paint booth valve actuation
Feeds the air-operated valves on a paint-mixing and dispensing skid: the finer 5 um filtration protects the pilot sections of the valves, the regulator fixes actuation pressure, and the lubricator is set per the valve maker's oil requirement.
Instrument air takeoff
Provides a conditioned local takeoff for panel instruments and positioners on a process line, combining 5 um filtration, a stable regulated pressure and, where the devices accept it, oil-mist lubrication from the same two-unit set.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AF1W) the Right Set?
The meaningful choice in this code is filtration: the W selects the 5 um element where the standard version carries 40 um. Pick 5 um when downstream directional valves, air bearings, paint equipment or measurement devices object to fine particulate; stay at 40 um for general cylinder and tool service. Everything else decodes as size 300, 1/4 inch PT port, automatic drain and the embedded square gauge in MPa, with a round external gauge in psi or bar scale orderable. Manual- and differential-drain variants and a K check-valve option exist in the same frame. PT is the standard thread, with G and NPT as catalogue options. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008AF1W) FAQ
AirTAC publishes flow for the G series as curves rather than a single rated number, so we cannot quote one figure honestly. Note also that a finer 5 um element sits in this version, which is worth checking against your demand. Share your working pressure and required flow and we will confirm the sizing from the datasheet curves on request.
Choose the W code when the equipment downstream of the unit is sensitive to fine particles, such as pilot-operated valves, pneumatic instrumentation or coating equipment. The standard 40 um element suits general cylinder and air-tool service and loads the element less. Both grades are catalogue options on the same GFC frame, so the choice is purely about the cleanliness your application needs.
