In the next step the filter tanks are assembled and all the different attachment parts are added.
The base cap is glued to the bottom.
The screws for the top cover, lateral inspection apertures and inspection windows are glued.
In the last step of the production the single components are all brought together and assembled with all the built-in and accessory parts.
In the two steps mentioned before a lot of the customer specific optional parts can be realised.
The connection dimensions e.g. are not only limited by the moulds, but are defined and individually installed in the assembling process.
