DA-SB-PTFE In-Line Detonation Flame Arrester

Brand: PROTEGO
The in-line detonation flame arresters type Protego DA-SB-PTFE are the latest generation of flame arresters and are distinguished by its unique resistance to adhesive and corrosive media.

The use of fluoroplastics as a high-tech housing coating and as solid material for the flame arrester element is unique throughout the world.

The speed of incoming detonations is highly reduced by the effective shock absorber and result in an equal pressure distribution across the FLAMEFILTER.

This improves the flame extinction in the narrow gaps of the original PTFE- FLAMEFILTER.
Features
  • Build up of adhesive materials is prevented by the smooth surfaces
  • Application especially for corrosive and polymerizing media
  • Minimum number of FLAMEFILTER discs due to the effective shock absorber
  • Different series allow increase of FLAMEFILTER size for given flange connection resulting in lower pressure drop across the device
  • Service-friendly design
  • The modular design enables each individual FLAMEFILTER to be replaced
  • Bidirectional operation as well as any direction of flow and installation position
  • Installation of temperature sensors is possible
  • Minimum pressure loss and less soiling of the device
