SIA makes Air Intake and Purification Plants by seeing to all phases of the process cycle: from measurements and design to estimating the execution of every single component at the various production sites. I appoints trained and qualified in-house personnel to the assembly work, and its technical/sales office is always available to both customers and potential customers to solve problems, remove doubts or simply to offer technical advice.

The resulting plants are the most modern, safest and most efficient that one could ever desire.

A selection of our plants follows.
