Airtac GFC Combination Unit GFC300C15MF1WK
The AirTAC GFC Combination Unit GFC300C15MF1WK 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 GFC300C15MF1WK
The GFC300C15MF1WK is an AirTAC G-series two-unit set: a filter-regulator plus a lubricator, providing filtration, pressure regulation and oil-mist lubrication in one ordered package. This configuration is size 300 with PT1/2 ports, drains the filter bowl manually, carries the finer 5 um filter element instead of the standard 40 um, includes an embedded square pressure gauge with MPa scale on the regulator, and has a reverse/check valve fitted. At size 300 the bowls are polycarbonate. Maximum working pressure is 1.0 MPa (145 psi); with the manual-drain arrangement the regulator adjusts from 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied for the US market. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options include G (BSPP) or NPT threads, automatic or differential-pressure drains, 40 um or 5 um elements, gauge scales and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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 GFC300C15MF1WK Is Used
Vehicle service bay tool air
Feeds impact wrenches, air ratchets and blow guns on 1/2 in service drops with filtered, regulated and lubricated air; the 5 um element and MPa gauge suit a general workshop setting.
CNC pallet-clamp circuits
Supplies workholding clamps and chip-auger cylinders on a machining centre, keeping pressure steady at the setpoint while the lubricator mists the actuator seals.
Bottling line actuator headers
Serves rinse, fill and capper cylinder banks where one FRL set conditions the whole header; the fitted check valve covers circuits where reverse-flow protection is specified.
Is the Airtac GFC Combination Unit GFC300C15MF1WK the Right Set?
Size 300 with PT1/2 ports sits mid-range in the G series; step down to 200 or up to 400 depending on the flow your circuit needs, since larger sizes carry larger ports and more flow. Manual drain suits points of use that are visited regularly; automatic or differential-pressure drain versions are available where bowls are not hand-drained. The 5 um element here is the finer filtration option over the standard 40 um. The square gauge reads in MPa; psi and bar scales can be ordered instead. PT is the standard thread, with G (BSPP) and NPT available as catalogue options. Because flow is published as curves rather than a single rating, 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 GFC300C15MF1WK FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the flow figures from the datasheet on request.
With this manual-drain version the regulator adjusts from 0.05-0.9 MPa (7-130 psi), whereas automatic and differential-pressure drain versions adjust from 0.15-0.9 MPa (20-130 psi). All versions share the 1.0 MPa (145 psi) maximum working pressure and the -5 to 70 C temperature range.
