The Safe Choice – since 1920

DPI is a leading company in the respiratory protection industry. We started safeguarding the health of workers around the world about 100 years ago.

Until the early 1990s the company was part of the Pirelli Prodotti Diversificati Group, of which it retains the historic Sèkur® brand; the brand is synonym of safety, quality and reliability. As of February 2021, the company became part of the Leonardo Group, following an acquisition made by Larimart S.p.A., thus gaining recognition as excellence in the respiratory protection industry.

DPI, which is ISO 9001 certified, holds a leading position not only in the Italian market, but is also an important reference point for foreign markets.

Experience and made in Italy

The company boasts MADE IN ITALY production of a wide range of devices, all coming from our factory in Rome: self-contained breathing devices, full-face masks, half-masks, dust filters, gas filters and combined filters, airline, wheeled devices, and escape breathing devices.

In-house R&D and experimental laboratory

Our R&D Center is focused on innovation, quality and design of our solutions, while our in-house experimental laboratory is the place where we can test them under the most extreme conditions; after, we start the production to provide users with the most advanced answers to any respiratory protection needs.


We own specialized skills in the CBRN, civil, and industrial sectors thanks to the experience gained with the Pirelli Group and enhanced by the Leonardo Group.


DPI is a nimble, flexible and consumer-oriented company through tailor-made solutions and projects that meet the customer needs.
