Airtac GC FRL Unit GC300C15MF1WK
The AirTAC GC FRL Unit GC300C15MF1WK 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 GC300C15MF1WK
GC300C15MF1WK is the fully specified build of this size 300 G-series F.R.L. set: a filter, regulator and lubricator on a 1/2 in PT supply line, fitted with the 5 um filter element (W) and a reverse/check valve at the inlet (K). The check valve blocks backflow through the unit and helps hold the regulated pressure downstream if the supply is interrupted, while the 5 um element provides the finer of the two catalogue filtration grades. A manual drain is fitted on the filter bowl, the square gauge is scaled in MPa, and 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; related options include G (BSPP) or NPT threads, automatic drains, the standard 40 um element, and external round gauges in psi or bar scale. 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 GC300C15MF1WK Is Used
Filling-head valves on a bottling line
Serves the product-dispensing valves and hold-down cylinders on a filling line; the 5 um element is specified for finer pre-filtration and the check valve holds set pressure at the head when the main is vented.
Precision air tools at a maintenance shop
Feeds a dedicated bench outlet for die grinders and drills in a maintenance workshop, with the check valve keeping the regulated setting stable if an upstream valve is closed.
Gantry clamp circuit on an automated press
Supplies the interlocked clamp cylinders around an automated press cell; the check valve maintains clamp-side pressure during supply dips while the FRL set cleans, regulates and lubricates the air.
Is the Airtac GC FRL Unit GC300C15MF1WK the Right Station?
This code combines the two main options in one build: W for the 5 um element where finer pre-filtration is required, and K for the check valve where supply dips must not pull downstream pressure back through the unit. It suits protected circuits on finishing, dosing and clamping duty at size 300 with a 1/2 in PT port. If the MPa gauge scale, PT thread or manual drain do not match your plant, G or NPT threads, psi/bar round gauges, an automatic drain and the 40 um element are all orderable in the same size.
Because G-series flow is published as curves rather than one rated figure, ask us to confirm the unit 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
- ✓ 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 GC300C15MF1WK FAQ
Flow for the G-series is published as performance curves, not as a single rated figure, so we will not quote a number blindly. Give us your working pressure and required consumption and we will confirm the sizing from the datasheet on request before you order.
PT is the standard thread for this code, and G (BSPP) or NPT are catalogue options you can specify when ordering - for example, NPT suits US plant piping. It is a specification choice, not a stock arrangement: state the thread you need on the order and the equivalent code is supplied. The 1/2 in port size stays the same either way.
