About the Airtac GC FRL Unit GC300C15MF1
GC300C15MF1 is a three-piece F.R.L. combination from AirTAC's G-series: a filter, a pressure regulator and a lubricator assembled as one size 300 unit for a 1/2 in PT supply line. In use it removes water and particulate from compressed air, holds a set downstream pressure and feeds a controlled oil mist to downstream actuators and tools. This code carries a manual drain on the filter bowl, the standard 40 um filter element and an embedded square pressure gauge scaled in MPa; with the manual-drain bowl, the 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, and options include G (BSPP) or NPT threads, automatic or manual drains, a 5 um element (code W), an external round gauge in psi or bar scale, and a reverse/check valve (code K). Maximum working pressure is 1.0 MPa (145 psi), the 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 GC300C15MF1 Is Used
CNC machining-center pneumatics
Feeds air-operated workholding clamps and chip-ejection jets on a machining center from the shop 1/2 in main, so clamps hold a consistent set pressure through every cycle.
Carton-forming packaging line
Supplies case erectors and flap-closing cylinders on a packaging line, where the lubricator keeps cylinder seals running on a controlled oil mist and the regulator stabilises pressure across the line.
Pick-and-place robot grippers
Serves the valve manifold feeding pneumatic grippers on a pick-and-place robot cell, combining filtered, regulated and lubricated air in one size 300 unit at the drop.
Is the Airtac GC FRL Unit GC300C15MF1 the Right Station?
Size 300 with a 1/2 in PT port is the mid step of the G-series; move up to 400/600 or down to 200 if the line needs a different port and flow capacity. The 40 um element is the standard grade for general plant air - choose code W (5 um) only where finer pre-filtration is genuinely needed ahead of sensitive components. Gauge scale is fixed here at MPa, but psi or bar round external gauges can be ordered, and the thread can be specified as G (BSPP) or NPT instead of PT. A check valve (K) can be added to hold downstream pressure when the supply drops.
Flow for G-series units is published as curves, not as a single rated figure, so ask us to confirm sizing against your actual 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 GC300C15MF1 FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so there is no one number we can quote. Tell us your inlet pressure and air demand and we will confirm the flow from the datasheet on request before you order.
In this code the M position specifies a manual drain on the filter bowl: condensate is emptied by hand, which suits lines checked routinely. Automatic (A) and differential-pressure (default) drains are available in the same size. With a manual-drain bowl the regulator range is 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure versions adjust over 0.15-0.9 MPa (20-130 psi).
