About the AirTAC GC300-15 FRL Unit (GC30015MC1)
The GC series is a three-unit air preparation set: a separate filter, regulator and lubricator, so compressed air is cleaned, regulated and oil-misted in one supply. This GC30015MC1 is the 300 size with PT1/2 ports, a manual drain on the filter bowl, a standard 40 um filter element and an external round gauge reading in MPa. Max working pressure is 1.0 MPa (145 psi), the manual-drain regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the 300-size bowls are polycarbonate (PC), with an operating range of -5 to 70 C.
It is a genuine AirTAC part. The G series runs from size 200 to 600, where larger sizes give larger ports and more flow, with options including automatic or differential-pressure drains, a 5 um element (W), G (BSPP) or NPT threads and a check valve (K). Flow is published as curves rather than a single rating, so we confirm the datasheet figures for your application 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 0.05 - 0.9 MPa (7 - 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: GF300-15 filter, GR300-15 regulator and GL300-15 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 GC300-15 FRL Unit (GC30015MC1) Is Used
CNC machining center supply
Feeds filtered, regulated and lubricated air to a machine tool's pallet clamps, tool-change cylinders and blow-off nozzles, with the 40 um element guarding the downstream valves.
Case-packing line actuators
Supplies the pushers, grippers and sealing cylinders on a carton case-packing conveyor, holding a set working pressure while the lubricator feeds oil mist to the seals.
Assembly plant drop lines
Installed as a point-of-use set at workstation drops in an assembly plant, combining water and particle removal, pressure setting and lubrication in a single order.
Is the AirTAC GC300-15 FRL Unit (GC30015MC1) the Right Station?
Size 300 with PT1/2 ports sits mid-range in the GC family; step to 200, 400 or 600 as your pipe and demand change. The M suffix means a manual drain, which suits attended lines where an operator blows down the bowls, and it also widens the regulator range to 0.05-0.9 MPa; choose A (automatic) or the differential-pressure default for unattended duty. The 40 um element is the standard grade - order the W variant if you want 5 um. This set carries a round external gauge on the MPa scale; psi and bar scales exist in the range. PT thread is the standard, with G (BSPP) and NPT as catalogue options. Because flow is published as curves, not one rating, ask us to confirm sizing against your application before ordering.
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
- ✓ 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 0.05 - 0.9 MPa (7 - 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC GC300-15 FRL Unit (GC30015MC1) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and air demand and we will confirm the sizing and datasheet figures for this 300-size, PT1/2 unit on request.
The M suffix specifies a manual drain on the filter bowl: an operator drains it, which suits attended lines with a walk-round routine. It also widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi), versus 0.15-0.9 MPa (20-130 psi) on automatic and differential-pressure drain versions.
