## Key features of Depulvera®
Depulvera® is based on **conservation principles applied in libraries and archives**, where dust accumulates mainly on the external surfaces of books, particularly on the top edge, which accounts for around 60% of the dust.
The system dusts automatically and non-invasively, avoiding the spine and ensuring uniform external dust removal. The machine requires two operators and allows **continuous operation at up to 12 books per minute**, making it particularly suitable **for handling large quantities of volumes**.
The mobile configuration allows **operation directly on the shelves**, avoiding the need to move the books. The open system is managed via HEPA filtration, ensuring **safe working conditions for operators and workspaces**.
Depulvera® is particularly **suitable for large libraries and repositories**, where rapid and continuous intervention is required on extensive collections. For daily cleaning, Pulvisina, with its more compact design, can be used, whilst for internal cleaning between the pages, Spirabilia is required, designed for manual and more delicate operations.

## How Depulvera® works
The book is positioned and supported along the page edges, keeping the volume stable during treatment.
The system rotates the volume by 180° to allow the outer surfaces to be treated.
The outer surfaces, cover and edges, are cleaned evenly.
Dust is extracted via a HEPA system, preventing it from being released into the environment.

## Frequently Asked Questions
**Does Depulvera® also clean the inside of the book?**
No, Depulvera® is designed for dusting the exterior of books.
It works on the cover and page edges, removing dust from the surfaces where it accumulates most.
For cleaning the inside of the pages, specific systems such as Spirabilia must be used, which are designed for manual and more delicate cleaning.
**Why isn’t the spine cleaned?**
The spine is the most fragile part of the binding and can easily be damaged by automated processes. For this reason, Depulvera® avoids treating the spine, favouring a non-invasive approach that preserves the integrity of the book.
**How many operators are needed to use Depulvera®?**
Two operators are required to use Depulvera®. This setup allows for the continuous handling of volumes, maintaining high productivity and control during the treatment.
**Can Depulvera® be used directly on the shelves?**
Yes, the mobile configuration allows you to operate directly next to the shelves. This avoids the need to move books and reduces the risks associated with handling them.
**When should Depulvera® be used instead of other cleaning systems?**
Depulvera® is suitable for automatic external dusting and the operational management of large quantities of books. For daily cleaning tasks, Pulvisina can be used, whilst for internal cleaning or on particularly delicate materials, Spirabilia should be used.
**Is the open system safe for operators?**
Yes, Depulvera® uses a HEPA filtration system that removes dust during the process. This ensures controlled and safe working conditions, even in environments with continuous operation.
