The AirTAC GC300C15ALF2 AirTAC F.R.L. Combination PT1/2 Low-Pressure 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).
The GC300C15ALF2 is a three-piece AirTAC G-series F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator working together as one air-preparation set. This size 300 unit is threaded PT1/2 (1/2 in, PT standard), and the code reads as follows: automatic drain on the filter bowl, standard 40 um filtration, a low-pressure regulator type, an embedded square gauge scaled in psi, and a mounting bracket included. The filter strips water and particulate before regulation, the regulator holds your set pressure, and the lubricator feeds a controlled oil mist to downstream cylinders and air tools. The polycarbonate bowl suits the unit's -5 to 70 C (non-freezing) range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The G-series combination is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT to order) and bracket. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.
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.

Point-of-use air preparation for impact wrenches and pneumatic nutrunners on a final assembly line, delivering clean, regulated and lubricated air at each workstation.
Supplies filtered, regulated and lubricated air to cylinder-driven pushers, diverters and clamp gates on a bottling or carton-packing conveyor line.
Conditions the pilot supply to pneumatically actuated control valves on a process skid, where a low-pressure regulator setting is required upstream of the positioners.
Every choice in this code is decodable. Size 300 with a 1/2 in PT port is a common step for lines with substantial air demand, but size the unit against required flow rather than port size alone. Drain type matters: this unit carries an automatic drain that discharges condensate without intervention; manual and differential-pressure drains are available on other codes. Filtration is the standard 40 um element, with a 5 um element (code W) offered where finer protection is needed. The gauge is the embedded square type scaled in psi; an external round gauge in MPa, psi or bar is optional. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the mounting bracket is included. The regulator here is the low-pressure type; its exact adjustment range is not published in the data we hold, so confirm it with us. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
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 publishes flow for this series as curves, not as a single rated number, so we do not quote a figure. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
This code carries an automatic drain, which discharges collected condensate from the filter bowl without anyone opening it - useful on lines that run unattended. Manual-drain and differential-pressure-drain versions exist in the same family; tell us which you prefer and we will identify the matching code.
