The hoods for Alsident® System 63 are all incl. a stub pipe.
Note: Conductive PP and transparent PETG withstand max. air temperature at 80° C.
The transparent hoods are made of PETG. Flange and stub pipe are of white polypropylene (PP).
The transparent PETG is resistant to most common detergents and cleaning with alcohol. The material is not resistant to aggressive chemicals and should be used for common use in non-aggressive environments.
The suction pen and the white hoods are made of the chemical resistant plastic polypropylene (PP). Flange and stub pipe are also made of PP. Polypropylene (PP) is resistant to various chemicals and can be cleaned with alcohol. Therefore, these hoods can be used in most aggressive working environments.
TUnder Optimal position of the hood you will find an explanation in greater detail of how to position the hood considering source and type of pollution..
