Airtac GC FRL Unit GC300C15MF1K
The AirTAC GC FRL Unit GC300C15MF1K is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GC FRL Unit GC300C15MF1K
GC300C15MF1K is the same three-piece G-series F.R.L. combination as the base code - size 300 filter, regulator and lubricator on a 1/2 in PT supply line - with one decode difference: the trailing K specifies a reverse/check valve fitted at the inlet. That valve prevents backflow through the unit, helping hold the regulated downstream pressure if the main supply is shut off or drops. This configuration has a manual drain on the filter bowl, the standard 40 um element and an embedded square gauge scaled in MPa; the manual-drain regulator adjusts over 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The G-series runs from size 200 to 600 with ports from 1/8 to 1 in; further options include G (BSPP) or NPT threads, automatic or manual drains, a 5 um element (W), and external round gauges in psi or bar. Maximum working pressure is 1.0 MPa (145 psi), temperature range is -5 to 70 C (non-freezing), and size 300 bowls are polycarbonate. Flow is published as curves rather than a single rating, so we confirm flow and 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 combination has no separate bracket code — the three 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. Constituent units, orderable separately as spares: GF300-C1 filter, GR300-C1 regulator and GL300-C1 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the Airtac GC FRL Unit GC300C15MF1K Is Used
Pneumatic clamping fixture, welding cell
Regulates and lubricates air to swing clamps on a welding fixture; the fitted check valve holds the clamped circuit's set pressure if the main supply is disconnected or drops.
Air-motor agitator on a mixing station
Runs the agitator drive at a paint or resin mixing station where the air motor needs continuous oil-mist lubrication, with the check valve stopping backflow when the station is isolated.
Lubricated tool outlet at an assembly bench
Feeds a bench outlet for nutrunners and impact drivers, giving operators filtered, regulated and lubricated air while the check valve protects the setting during line shutdowns.
Is the Airtac GC FRL Unit GC300C15MF1K the Right Station?
The K option is worth choosing wherever a sudden supply loss would let downstream pressure bleed back through the unit - clamping circuits, isolated machine drops and intermittently vented lines. Otherwise the choices mirror the base model: size 300 with a 1/2 in PT port, standard 40 um filtration, MPa square gauge and manual drain; G or NPT threads, automatic drain, 5 um element (W) and psi/bar round gauges are all orderable in the same size.
G-series flow is given as curves, not one rated figure, so ask us to check the unit against your real air demand 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
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter 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 station 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 of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C15MF1K FAQ
Flow for the G-series is published as curves rather than a single rated number, so the honest answer is to match the curves to your demand. Send us your working pressure and required air consumption and we will confirm the sizing from the datasheet on request before you order.
The K specifies that a reverse/check valve is fitted, which blocks backflow through the unit and helps hold the regulated downstream pressure when the upstream supply is dropped. Everything else decodes as the standard build: size 300, 1/2 in PT port, manual drain, 40 um element and a square MPa gauge. The same K option is available across the G-series sizes.
