AirTAC GFC300-15 Combination Unit (GFC30015MLF1)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MLF1) 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 PT1/2" ports, a 40 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015MLF1)
The AirTAC GFC series is a two-piece air preparation set: a filter regulator plus a separate lubricator, so one installation filters, regulates and lubricates the compressed air supply. This GFC30015MLF1 is the size 300 unit with PT1/2 ports (PT thread is the standard), a manual drain bowl, the L low-pressure regulator type, a factory-fitted square pressure gauge scaled in MPa, and the standard 40 um filter element. Maximum working pressure is 1.0 MPa (145 psi), the manual-drain regulator setting range is 0.05-0.9 MPa (7-130 psi), and operating temperature is -5 to 70 C (non-freezing). The size 300 bowls on both the filter regulator and the lubricator are PC (polycarbonate).
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, with PT, G(BSPP) or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um (W) elements, gauge variants and optional brackets across the range. Flow is published as curves rather than a single rating, so ask us to confirm sizing and full datasheet figures for your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GFR300-15 filter regulator and GL300-15 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 GFC300-15 Combination Unit (GFC30015MLF1) Is Used
Pneumatic stamping press air supply
Mounted at the press inlet, the filter regulator holds a steady, low working pressure to the press cylinders while the lubricator carries a fine oil mist to keep seals and valve spools working smoothly on every stroke.
Bottling line capper and sorter actuators
On a filling or bottling line, the set cleans the plant air, sets the exact pressure the capper and diverter cylinders were designed for, and oils the actuators so high-cycle motion stays consistent through a shift.
Machine tool fixture clamping circuit
Feeding a CNC fixture clamping manifold, the unit removes water and 40 um particulate before the valves, regulates clamping pressure with the MPa square gauge in view, and lubricates the clamp cylinders.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MLF1) the Right Set?
Start with size and port: 200 to 600 covers small point-of-use drops up to large machine headers, and stepping up a size gives a larger port and more flow capacity. This unit is size 300 with PT1/2 ports; G and NPT threads are catalogue options if your piping is BSPP or NPT. Drain type matters: this M code is the manual drain variant, which also widens the regulator setting range to 0.05-0.9 MPa (7-130 psi); automatic (A) and differential-pressure (default) drain variants are available. This is the L low-pressure type, and the element is the standard 40 um grade - choose W for 5 um filtration. The square gauge here is scaled in MPa; psi and bar scales and an external round gauge are options. Gauge-less (N) variants and bracket choices also exist.
Because AirTAC publishes flow only as curves, not a single rated figure, ask us to confirm sizing against your actual air demand before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GFR300-15 filter regulator on its own.
AirTAC GFC300-15 Combination Unit (GFC30015MLF1) FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated number, so there is no one figure we can honestly quote here. Send us your line pressure and required air consumption and we will confirm the correct size and the datasheet curve figures on request.
M is the manual drain, L is the low-pressure regulator type, F is the factory-fitted square gauge and 1 is the MPa gauge scale. Manual drain variants have a wider 0.05-0.9 MPa (7-130 psi) setting range; automatic (A) and differential-pressure (default) drain versions of the same set are available if you cannot drain the bowl by hand.
