The AirTAC AirTAC GC300-15 FRL Unit (GC30015ALF1) 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 PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
GC30015ALF1 is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one 300-size station for compressed air only. The 1/2 in PT port suits a main drop feeding several downstream circuits. The automatic drain opens the filter bowl as condensate collects, the standard 40 um element handles general-purpose particulate removal, and the low-pressure (L) regulator type is set up for circuits running below standard line pressure. An embedded square gauge on an MPa scale shows the regulated downstream pressure, and the lubricator meters oil mist into the air stream.
The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, available as single units, two-unit sets or three-unit combinations in PT, G (BSPP) or NPT threads. On this 300 size the bowls are PC (polycarbonate), operating temperature is -5 to 70 C (non-freezing) and maximum working pressure is 1.0 MPa (145 psi). Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Conditioning the air feed to a carton sealer's clamp and pusher cylinders on a packaging line, with automatic bowl draining so condensate is handled without operator rounds.
Filtering, regulating and lubricating air to pneumatic clamps and swing cylinders at an assembly workstation, with the square gauge letting operators see the clamping pressure at a glance.
Serving a 1/2 in plant-air drop that feeds air tools and blow-off stations, combining water and particle removal, pressure setting and oil-mist lubrication in one station.
This configuration gives you a 300-size F.R.L. with a 1/2 in PT port, automatic drain, standard 40 um element and an embedded square MPa-scale gauge. Step to a 200 or 400/600 size if your flow sits below or above what this port serves. The drain can be ordered as manual (M) or differential-pressure (blank) instead of automatic (A), the element as 5 um (W) for finer filtration, and the gauge as an external round type with scale 2 (psi) or 3 (bar). The thread can be ordered as G (BSPP) or NPT instead of the standard PT. Because this is the L (low-pressure) type, confirm the exact adjustment range for your set pressure with us before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes G-series flow as curves, not as a single rated figure, so there is no single number to quote. Send us your inlet pressure and air demand and we will confirm the curve and datasheet figures for this exact model on request.
F is the embedded square gauge and 1 is the MPa scale; a C code would give an external round gauge instead, and scales 2 (psi) or 3 (bar) can be ordered. Tell us the scale your operators prefer and we will confirm the option on request.
