Aspirazione Vapori Colla Bordatrice

[ziozeus]

Buongiorno a tutti.

Ho cercato nel forum, ma non ho trovato trattazioni a riguardo per cui apro un post.

Ho acquistato una bordatrice usata con gruppo incollaggio fuori dal carter e senza aspirazione dedicata.
I vapori sono insostenibili, e cmq il problema va affrontato per il bene di chi vive in laboratorio.
Le alternative sono
1) cappa con filtro dedicato senza espulsione all'esterno (può in qualche modo essere sufficiente?)
2) cappa con tubo e camino di espulsione dedicato all'esterno (e relativa denuncia ad organi provinciali?)
3) cappa con collegamento all'impianto di aspirazione generale (e relativa denuncia ad organi provinciali?)

Vorrei seguire la strada 3) ma il dubbio più grande che ho è: ci sono problemi per quanto riguarda ATEX per l'eventuale deposito di materiale esplosivo all'interno dei condotti di aspirazione (deposito di mix polveri / colla) ?!

Grazie

una colla meno fetente ? la colla spero non contenga cianuro.... altrimenti ...
Io prima mi muoverei sul lato colla e poi eventualmente cercherei un filtro senza emissione tipo quelli da saldatura con filtro anche ai carboni attivi per l'odore. ma l'odore che si sprigiona in atmosfera non lo togli più , a meno di filtraggi di aria importanti.

La colla è una EVA (a base etilene vinil acetato) che si usa normalmente sulle bordatrici.
Nella fattispecie si tratta di una Jowatherm 280.00 e la scheda tecnica dice quanto segue (se a qualcuno può interessare)
