*Transparent PETG with PP stub
The hoods for Alsident® System 100 are all incl. a stub pipe.

System 100 AL:

The hoods for System 100 AL are made of transparent PETG and  aluminium - both anodized and powder coated.The white plastic parts are made of polypropylene (PP). The hoods of transparent PETG are resistant to most common detergents and cleaning with alcohol. 
System 100 AL extraction arms and hoods are for the use in common working environments without any specific requirements to conductivity or chemical resistance

System 100 AS:

It is important to select an antistatic hood for the antistatic extraction arm to keep the conductivity. It is highly important when the extraction arm is mounted in ESD areas and EX areas (ATEX).
The antistatic hoods are in chromated (TCP) aluminium or conductive polypropylene (PP) - depending on the model. 

System 100 PP:

The material of the hoods are chemical resistant polypropylene (PP) or powder coated aluminium.
The two round hoods and the flat screen are all made of 100% PP. PP is resistant to a wide selection of chemicals and consequently, the PP hoods are applicable to most aggressive working environments. However, metal hood Dia. 200 is made of powder coated aluminium which makes it less resistant. The chemical resistant extraction arms with  System 100 PP hoods are applicable to chemically aggressive working environments.

Optimal position of the hood:

Under the menu "Optimal position of the hood"  you find an explanation in greater detail of how to position the hood considering source and type of pollution.
