The three-way cleaning concept from PURItech

1 – Filter cleaning without exchange module

Send the filter module with the enclosed return delivery note to PURItech for cleaning. Once the filter cleaning has been completed, the cleaned filter module is returned to you for reinstallation.

2 – Filter cleaning with exchange module

We only offer this service for commercial vehicles (on road).
If you order in time – i.e. at least one week before maintenance or installation – PURItech will supply you with a replacement module.
After receipt of the replacement module, the filter module to be cleaned is replaced by the replacement module and sent to PURItech. This measure significantly reduces the service life of the vehicle and avoids unnecessary visits to the workshop.

3 – Filter cleaning at the customer/service partner’s premises

You order a filter cleaning procedure in the good time with the rental of a silencer module from PURItech. When the silencer module arrives, remove the filter module to be cleaned and temporarily replace it with the silencer.

Your filter module will be sent to PURItech for cleaning. After the cleaning process we send your filter module back to you and you send the silencer back to PURItech.
