Laser & CNC — non-metal
Acrylic, paper, leather, textiles, resin 3D
For CO₂ laser cutting and engraving of acrylic, paper, card, leather, textiles and technical plastics, and for resin-based 3D printing. The FS series combines a large-area F9 pre-filter, a HEPA H14 stage and an activated carbon bed, sized by the bed of the machine: 30×40 cm up to 130×250 cm. If the machine also cuts wood or MDF, use the FGS series instead.
11 machines →Laser & CNC — wood, plywood & MDF
Resinous, sticky dust from board materials
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.
4 machines →Laser marking & coding
Sub-micron fume from fibre and CO₂ marking
Fibre and CO₂ laser marking produces metal oxide fume and plastic vapour that is almost entirely sub-micron — invisible, and it does not settle. The F series covers a single bench-top marking station; the DS series covers marking cells and inline stations, adding an activated carbon bed for odour.
12 machines →Metal & composites — cutting, welding, cleaning
High vacuum and high volume for metal work
Metal processing covers two very different jobs. At a single station — laser scribing, drilling, welding, deburring, metal AM — what matters is negative pressure at the nozzle, which is what the compact D series delivers at up to 10000 Pa. On a full cutting bed, what matters is volume and continuous running, which is why the industrial D units use a self-cleaning cartridge bank. The DFS series covers carbon fibre, composites and laser cleaning, where the dust is abrasive, conductive or still burning.
20 machines →Explosion-proof — aluminium, magnesium, titanium
Combustible dust, built ATEX-minded
Aluminium, magnesium-aluminium alloy and titanium produce combustible dust. A conventional collector concentrates precisely the fuel and the ignition sources needed for a deflagration. The DE series is built explosion-proof throughout, with antistatic flame retardant cartridges and automatic pulse-jet cleaning. PURE-AIR states this is mandatory, not optional, for these materials and wherever flammable gases are present.
3 machines →Printing — inkjet, UV & sublimation
Ink aerosol, solvent vapour and odour
Printing produces ink aerosol, solvent vapour and odour rather than dust — and wet aerosol ruins the pleated media of a standard dust extractor. The FVS series puts a washable open-cell foam stage in front of the F9, HEPA H14 and carbon stages, so the aerosol is caught before it reaches anything it can damage.
11 machines →About this range
Industrial fume extraction and dust collection for laser, CNC, 3D printing and printing machines. PURE-AIR units capture smoke, dust, VOC and odour at the source and return filtered air to the workshop, so no external ducting is required on the mobile models. Choose by the process and the material you cut — the material decides the filter, and the wrong filter is the most expensive mistake in this category.
| What you process | Series | Why that one |
|---|---|---|
| Acrylic, paper, leather, textiles, resin 3D | FS | F9 pleated pre-filter |
| Wood, plywood, MDF | FGS | PTFE cartridge — sticky dust releases |
| Carbon fibre, composites, laser cleaning | DFS | Flame retardant cartridge, antistatic duct |
| Laser marking and coding | F · DS | Sub-micron fume, carbon for odour |
| Metal — one station (weld, drill, AM) | D compact | Up to 10 000 Pa at the nozzle |
| Metal — a full cutting bed | D industrial | Volume plus self-cleaning cartridges |
| Aluminium, magnesium, titanium | DE — explosion-proof | Combustible dust — required, not an upgrade |
| UV, inkjet, sublimation printing | FVS | Foam stage catches wet ink aerosol |
Then size it: the machine bed decides the airflow — 30×40 cm needs 300 m³/h, 130×250 cm needs 2400 m³/h.
Frequently asked questions
How do I choose the right extractor?
Four things decide it: the machine and its working format, the materials you process, how many hours a day it runs, and whether the workshop has any flammable dust or gas. Send us those and we size it; guessing from airflow alone is how people end up with a unit that cannot pull through its own filters.
When is an explosion-proof unit mandatory?
Whenever you process aluminium, magnesium-aluminium alloy, titanium or another combustible metal, and anywhere flammable gases are present. This is not an upgrade option: a standard collector concentrates exactly the fuel and the ignition sources a deflagration needs. Everywhere else, a standard unit is the correct choice.
Does the filter set change with the material?
Yes, and it is the main thing you are choosing. Metal work needs a spark arrestor ahead of a flame retardant element. Wood, plywood and MDF need the anti-stick PTFE cartridge, because resinous dust cakes onto pleated media. Ink aerosol from printing needs the washable foam stage first. Humid extraction needs moisture-resistant media.
Will it run on our supply?
Standard models take 220 V single-phase; the high-power units need 380 V three-phase. Export versions can be supplied for 110 V single-phase, or 220, 400, 415 and 440 V three-phase. The wide-voltage design tolerates ±10%; beyond that, fit a stabiliser.
How long does a filter last, and how will I know?
It depends entirely on load, so nobody can quote you a number honestly. Every unit monitors filter status; the "i" models show it live on screen and warn you before the element is finished, so a replacement can be ordered rather than improvised.
What controls does it have?
Standard models: a key panel. The "i" models add remote start and stop over I/O, RS-485, and linkage into a production line or MES. Several units can be networked over RS-485 for centralised start-stop and coordinated airflow across a workshop.
