About this range

Wood, plywood and MDF produce resinous, sticky dust that cakes onto a standard pleated pre-filter and blinds it within weeks. The FGS series uses a PTFE cartridge loaded with natural mineral powder, so the dust releases instead of bonding. This is the range PURE-AIR itself recommends for CO₂ laser cutting of board materials, and it suits CNC routers working the same materials.

How a PURE-AIR unit cleans the air. Only stage 1 changes between series — that is what you are choosing when you pick FS, FGS or DFS.

  • Airflow held steady as the filter loads

  • I/O and RS-485 — starts with the machine

Both are current models. PIPS earns its place where the unit runs unattended, feeds a line, or has to prove it is working.

Then size it: the machine bed decides the airflow — 30×40 cm needs 300 m³/h, 130×250 cm needs 2400 m³/h.

The material decides the filter. Picking by airflow alone is the mistake that blinds a filter in weeks.

Frequently asked questions

Why does my filter blind so quickly?

Three usual causes: sparks not caught upstream burning through the element, dust concentration above what the pre-filter was sized for, or humidity caking the dust onto the media. On board materials it is almost always the media itself — pleated media holds resinous dust, PTFE releases it.

Where does the filtered air go?

Back into the room. The mobile units are recirculating, so there is no duct to the outside and no heated air thrown away in winter. The central industrial units are ducted to the machine enclosure and need a compressed-air line for their self-cleaning cartridges.

What maintenance does it need day to day?

Check the element is seated and sealed before running. When the blockage alarm shows, replace it then — running on past it pushes fume into the fan and the control board, which turns a filter change into a repair.
