The AirTAC GC300C08AF2W AirTAC F.R.L. Combination, PT1/4, 5 um 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 GC300C08AF2W is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This size 300 configuration is threaded PT1/4 (1/4 in), carries a 5 um filter element for finer water and particulate removal, and drains its filter bowl automatically, so condensate is ejected without daily attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an embedded square gauge with a psi scale is fitted so the set pressure can be read at a glance. The set is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -5 to 70 C in non-freezing conditions; at this size the bowls are polycarbonate.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, automatic or manual bowl drainage, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and an included mounting bracket. Rated flow for this combination is published as curves rather than a single figure, so ask us to confirm the datasheet numbers for your application before you order.

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-C0 filter, GR300-C0 regulator and GL300-C0 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.

Feeds spray guns and atomising stations on a finishing line with water and particulate removed at 5 um, pressure held steady at the gun, and a light oil mist to keep air motors and triggers running smoothly.
Supplies the pneumatic clamps, tool-changer actuators and air-blast nozzles on a machining centre, where regulated pressure protects clamping force and clean, lubricated air extends cylinder seal life.
Prepares the air feeding grippers, diverters and case-erector cylinders along a packaging conveyor, with automatic drainage handling condensate during continuous shifts and the psi gauge letting line staff verify set pressure at a glance.
Choose the size by the port and flow step: size 300 with its PT1/4 port suits lines plumbed with 1/4 in air piping, while stepping up to size 400 or 600 gives a larger port and more flow capacity. Drainage here is automatic, the right choice when the unit is mounted where daily manual draining is impractical; a manual-drain variant suits very dry installations or easily reached bowls. The 5 um element (code W) is fitted instead of the standard 40 um element - keep it where downstream valves, cylinders or instruments tolerate less particulate, and note that a finer element loads with contamination faster. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are available as alternatives. Thread is PT as standard, with G and NPT offered as order options, and the mounting bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements and we will confirm sizing against the datasheet 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your required flow and working pressure and we will confirm the figures from the datasheet for this exact PT1/4, size 300 configuration before you order.
The W in the model code specifies the 5 um element in place of the standard 40 um element. It removes finer particulate, which suits downstream valves, cylinders and instruments that tolerate less contamination; the trade-off is that a finer element holds dirt sooner, so the automatic drain and periodic element checks matter more. If your line only needs coarse water and dirt removal, the 40 um standard grade is the lower-maintenance choice.
