About this machine
The PA-DFS2400 handles the two jobs that destroy ordinary filter media: cutting carbon fibre and composite laminates such as CFRP and CMC, and laser cleaning of painted or oxidised parts. Carbon fibre dust is abrasive and electrically conductive; paint removal produces hot, partly burning particles. The pre-filter is therefore a flame retardant PTFE cartridge, followed by HEPA H14 and activated carbon. 2400 m³/h at up to 10000 Pa.
Filtration
- Flame retardant PTFE cartridge pre-filter - for abrasive, conductive and potentially smouldering dust
- H14 deeppleat filter, 99.99% @ 0.3 um
- Treated activated carbon, approx. 12-30 kg

Standard version (PPS)
This is the standard version, without the intelligent control package. From 15 September 2026 PURE-AIR supplies these units with a colour LCD touch screen and an upgraded control system. If the intelligent functions matter - real airflow readout, filter warnings, automatic compensation, RS-485 linkage - choose the i version of the same model.
Installation
Free-standing on castors, or ducted to an enclosed cutting cell. Use earthed, antistatic ducting when cutting carbon fibre - the dust is electrically conductive. Leave the front clear for cartridge changes.

Frequently asked questions
What is it for?
The PA-DFS2400 is for two jobs that destroy ordinary filter media: cutting carbon fibre and composite laminates such as CFRP and CMC, and laser cleaning of painted or oxidised parts. It suits laser cutting of composite panels, CNC trimming and machining of composites, and handheld or robotic laser cleaning stations. It moves 2400 m³/h at up to 10,000 Pa.
Why a flame retardant PTFE pre-filter?
Carbon fibre dust is abrasive and electrically conductive, and paint removal produces hot, partly burning particles. So the first stage is a flame retardant PTFE cartridge, followed by an H14 deeppleat filter (99.99% @ 0.3 µm) and approx. 12–30 kg of treated activated carbon.
How should we duct it?
Free-standing on castors next to the machine, or ducted to an enclosed cutting cell, through a 200 mm inlet. When cutting carbon fibre use earthed, antistatic ducting, because the dust is electrically conductive. Leave the front clear for cartridge changes.
What does it need on site?
A 90–110 V or 210–257 V single-phase, 50/60 Hz supply for a rated power of 3.5 kW, and floor space for a unit of 750 × 907 × 1698 mm (W × D × H) weighing 237 kg net. Noise is below 68 dB(A) at 1 m. It is not explosion-proof.
What is the difference between the PA-DFS2400 and the PA-DFS2400i?
Extraction and filtration are the same; the difference is the control. The PA-DFS2400 has PPS standard control. From 15 September 2026 PURE-AIR supplies these units with a colour LCD touch screen and an upgraded control system. The PA-DFS2400i adds real airflow and pressure readout, filter warnings, automatic airflow compensation, and I/O and RS-485 linkage with your machine or line.
