AirTAC GFC300-08 Combination Unit (GFC30008MC1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008MC1W) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008MC1W)
The AirTAC GFC series combines a filter-regulator and a lubricator as one two-unit set, covering filtration, pressure regulation and oil-mist lubrication in a single order. This GFC30008MC1W is the size 300 set with PT1/4 ports, a manual drain on the filter-regulator bowl, the fine 5 um filter element (W suffix), and an external round gauge reading in MPa. Maximum working pressure is 1.0 MPa (145 psi); with this manual-drain configuration the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); operating temperature is -5 to 70 C (non-freezing). The bowls on this size 300 set are polycarbonate (PC).
This is a genuine AirTAC part for the US market. The GFC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in. to 1 in., ordered with your choice of drain type, 40 um or 5 um filtration, gauge and scale, reverse valve, and G (BSPP) or NPT threads in place of the PT standard. Flow for the G series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet flow data 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 0.05 - 0.9 MPa (7 - 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 (GFC30008MC1W) Is Used
Lab automation skid
On an analytical or test-bench skid with small pilot valves and actuators, the 5 um element screens fine particulate before it reaches sensitive pilot stages, the regulator sets a stable working pressure, and the lubricator services the actuator seals.
Pneumatic control panel feed
Installed as the point-of-use supply for a machine's valve manifold, the set filters the plant air to 5 um, locks in the pressure the logic circuit was set up with, and keeps a continuous oil mist on the moving valve parts.
Trailer brake test bench
On a workshop test bench for commercial-vehicle air components, the unit cleans and regulates shop supply to the pressure the test procedure calls for, with the round MPa gauge giving the technician a clear reading at the panel.
Is the AirTAC GFC300-08 Combination Unit (GFC30008MC1W) the Right Set?
Size 300 with 1/4 in. PT ports is the middle step of the G-series line-up; size the set from your measured air demand and step to size 400 (1/2 in. ports) if your flow sits near the top of the size 300 curves. The W in this code selects the 5 um element instead of the 40 um standard - the right choice when precision valves or air bearings sit downstream, with the trade-off of more frequent element checks. The manual drain suits attended installations; specify the automatic-drain code for unattended duty. The gauge is the external round type on an MPa scale (psi scale available). Threads are PT as standard; order G (BSPP) or NPT to suit your pipework. Flow is published as curves, not one rating, so 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 0.05 - 0.9 MPa (7 - 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 (GFC30008MC1W) FAQ
AirTAC publishes flow for the G series as performance curves, not as a single rated figure, so we do not state a rated flow here. Send us your flow and pressure conditions and we will confirm the datasheet curves for this 1/4 in. two-unit set on request.
The standard element filters to 40 um, which suits general plant air. The W suffix in this code selects a 5 um element for downstream equipment that needs finer protection, such as precision valves or pilot circuits; the finer element should be inspected and serviced more often, and the manual drain keeps the bowl cleared.
