About the AirTAC GC300-10 FRL Unit (GC30010ALC1)
The AirTAC GC series combines a separate air filter, pressure regulator and lubricator in one three-unit F.R.L. set for compressed air. This GC30010ALC1 is a size 300 unit with 3/8 in PT ports in the low-pressure type (L code), intended for lines where the working pressure sits well below the standard setpoints. The filter uses the standard 40 um element, the bowls drain automatically, and the regulator carries an external round gauge scaled in MPa. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series air-treatment family, available in sizes 200, 300, 400 and 600 with a choice of ports, drains, filter grades, regulator types and gauge scales. On size 300 the filter and lubricator bowls are PC (polycarbonate). Because the low-pressure type has its own setting characteristics, ask us to confirm its adjustment range and the datasheet flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010ALC1) Is Used
Textile loom auxiliaries
Air treatment for loom and winding-machine assist circuits that run at gentle setpoints, where the low-pressure regulator type gives finer control and the 3/8 in main feeds multiple small actuators.
Woodworking hold-down clamps
Supplying hold-down and pusher clamps on a panel saw or CNC router bench at low working pressures, with automatic drains handling condensate through dusty, multi-shift shop operation.
Low-pressure air knife line
Regulating and lubricating the supply to a gentle air-knife drying station on a bottling or canning line, where product-safe low pressures and MPa-scale setting keep the blower-assist circuit repeatable.
Is the AirTAC GC300-10 FRL Unit (GC30010ALC1) the Right Station?
The L in this code selects the low-pressure regulator type - choose it when your process runs at modest setpoints and a standard regulator would be working at the very bottom of its range. Size 300 with 3/8 in PT ports is the mid step of the GC range; step to 400 for more flow capacity or 200 for compact branches. Drain is automatic (A), so the bowls empty without operator attention; manual and differential-pressure variants exist. Filter grade is the standard 40 um element, with 5 um W codes available. The round gauge reads in MPa (C1); psi and bar scales are offered. PT thread is standard, with G (BSPP) and NPT to order, plus an optional bracket. Confirm the low-pressure adjustment range and flow curves with us on request before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010ALC1) FAQ
Flow for the GC series is published as curves rather than a single rated figure, and the low-pressure (L) regulator type has its own setting range, so we do not quote numbers here. Tell us your line pressure and setpoint and we will confirm the datasheet curves and adjustment range for this unit on request.
It marks the low-pressure regulator type within the GC series, chosen for lines that operate at lower setpoints where a standard regulator has limited usable adjustment. Everything else decodes normally: GC three-unit F.R.L., size 300, 3/8 in PT port, A automatic drain, C1 external round gauge on an MPa scale, and the standard 40 um filter element.
