Airtac GFC Combination Unit GFC300C15MF1K
The AirTAC GFC Combination Unit GFC300C15MF1K 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 GFC300C15MF1K
GFC300C15MF1K is a two-piece AirTAC G-series air-treatment set: a filter-regulator paired with a lubricator, so the compressed air is filtered, regulated and then oil-mist lubricated in one group. This configuration has 1/2 in PT ports, a manual drain on the filter bowl, the standard 40 um filter element, a square gauge scaled in MPa, and a reverse (check) valve fitted. Both bowls on this 300 size are polycarbonate.
This is a genuine AirTAC part. The GFC two-unit sets are offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and this model runs at up to 1.0 MPa (145 psi) inlet with a 0.05-0.9 MPa (7-130 psi) regulating range. Flow for the set is published as performance curves rather than a single rating, so we confirm the datasheet figures 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 GFC300C15MF1K Is Used
Paint spray booth regulation
Regulating and lubricating the atomizing air to spray guns in a paint booth, with the check valve protecting the set pressure against line backflow during shutdowns.
Pneumatic valve manifold skid
Conditioning the air ahead of a solenoid valve manifold on a process skid, giving the valves filtered, oiled air at one fixed pressure even if upstream supply fluctuates.
Injection mold ejection circuits
Supplying the air-eject and core-pull circuits on an injection molding press, where the lubricator feeds the actuation and the check valve holds circuit pressure between strokes.
Is the Airtac GFC Combination Unit GFC300C15MF1K the Right Set?
In the G-series you step from size 200 to 600 as port size and required flow grow; the 300 size with 1/2 in PT threads is aimed at medium machine supply lines. Drain type is a real choice: this code carries a manual drain, whose regulator allows a 0.05-0.9 MPa (7-130 psi) setting, while automatic-drain and differential-pressure variants exist in the series. The element is the standard 40 um grade; a 5 um version (W) is a catalogue option. The gauge is the square type in MPa, and psi or bar scales are also available. The K suffix fits a reverse (check) valve, useful where backflow must be prevented. Thread is PT as standard, with G (BSPP) and NPT orderable, and bracket mounting is optional. 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 GFC300C15MF1K FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and demand and we will confirm the datasheet flow figures for this exact model on request.
K indicates that a reverse (check) valve is fitted in this version, preventing backflow through the unit. The equivalent model without the K, GFC300C15MF1, is otherwise identical, so choose based on whether your circuit needs that protection.
