The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC30008AC1WK is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GFC two-unit set combines a filter regulator and a lubricator in a matched pair, so one order gives you filtration, pressure regulation and oil-mist lubrication for compressed air. This GFC30008AC1WK is the 300 size with PT1/4 ports, a 5 um filter element, an automatic drain on the bowl, a check valve in the regulator section and a round pressure gauge reading in MPa. In use it cleans the air to a finer grade, holds your set pressure and feeds a controlled oil mist downstream, while the auto drain keeps the bowl emptying itself.
This is a genuine AirTAC part from the G series, which spans the 200, 300, 400 and 600 sizes, with a choice of filter grade, drain type, gauge scale and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C. Flow figures are published as curves rather than a single rating, so ask us and we will 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 0.15 - 0.9 MPa (20 - 130 psi). The set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Feeds filtered, regulated and lubricated air to the tool-changer and clamping cylinders on a CNC machining centre, keeping the supply clean to 5 um while the round MPa gauge shows set pressure at a glance.
Supplies the air cylinders that index and divert bottles on a filling line, with the lubricator maintaining an oil mist for cylinder life and the auto drain handling condensate on a continuously running line.
Mounted at the point of use on carton-forming and sealing equipment, the two-unit set gives one connection point for clean air, stable pressure and lubrication instead of three separate components.
The 300 size with 1/4-inch PT ports suits typical machine-supply lines; step up to 400 or 600 if your line needs more flow, or down to 200 for compact panels. The automatic drain here suits unattended duty; choose manual if you drain by hand, or the differential-pressure default where you want draining only when the bowl load justifies it. The 5 um element (W code) is the finer option over the 40 um standard, the round gauge reads in MPa, and G (BSPP) or NPT threads can be ordered instead of the standard PT. Flow is published as curves, not a single rated number, so send us your application and we will confirm sizing from 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
AirTAC publishes flow for this set as characteristic curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your working pressure and demand and we will confirm the flow figures from the datasheet on request before you order.
The K code fits a reverse (check) valve in the regulator section so downstream pressure is held if the upstream supply drops, and the W code selects the 5 um filter element instead of the 40 um standard. Both are catalogue options on the GFC two-unit set, and the drain here is automatic.
