System 75 AL:
The transparent PETG hoods are resistant to most allround cleaning detergents.
The hoods can be used together with the System 75 AL extraction arms in working environments with no special requirement for conductivity or chemical resistance
System 75 AS:
It is important to choose an antistatic
hood if you have chosen an antistatic extraction arm in order to maintain the conductivity. This is particularly important, if the System 75 AS extraction arm is to be mounted in an ESD area
or an EX area
The antistatic hoods are made of chromated (TCP) aluminium or conductive polypropylene (PP) depending on the chosen model.
System 75 PP:
The hoods for system 75 PP are available in two materials: chemical resistant polypropylene (PP) or powder coated aluminium.
The four hoods in 100% PP are resistant to various chemicals and are therefore applicable in most aggressive working environments.
The metal hood Ø200 is made of powder coated aluminium.
The chemical resistant hoods together with the System 75 PP extraction arms are applicable in chemical aggressive working environments.
Optimal position of the hood:
Under "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.
