Triple-Function Microperforated Ducts for Air Treatment and Smoke Extraction


An innovative single-compartment system with triple HVAC/SEFFC functionality, certified for smoke extraction.



Aspiration nozzles in SEFFC mode


Microperforations in HVAC mode

The innovative MICROFIRE system combines air supply and exhaust functions in HVAC mode and hot smoke extraction in SEFFC mode during fires, utilizing induction technology that treats ambient air and recirculates it from the same channel.

This system is suitable for both hot and cold environments, does not require insulation, and does not stratify ambient air.

The ducts, which can be installed visibly due to their modern design, are interconnected using special junction collars without flanges and bolts, enhancing aesthetics and optimizing ceiling space for reduced installation costs.

Using specific calculation software, you can visualize air diffusion in the treated area.
The generated graphs allow detailed analysis of both air penetration concerning the room volume and isometric velocity lines.

Air diffusion is more homogeneous compared to traditional systems with diffusers or nozzles.
Furthermore, by drastically reducing stratification, start-up and system maintenance times are reduced.


FUMOVENT System Management Center with Redundant Technology

For large-scale smoke extraction systems with numerous scenarios and components, the ideal management solution is undoubtedly the FUMOVENT® SF 3000 center, designed to handle numerous complex scenarios and provide redundant technology.

In case of control board failure, the system can continue functioning seamlessly with fully redundant electronics.

This ensures that SEFFC - FUMOVENT® systems have very high reliability compared to traditional systems on the market.



Not only is the microprocessor structure duplicated, but also all other structures, components, and parts of the system.


Control Panels for the FUMOVENT System

Suitable for installations requiring management of numerous scenarios, with a system layout panel and manual control for SEFFC system fire safety valves (VVF).

The system is equipped with supervision using a dedicated PC for regulating extraction flows and components in the field. Direct system management via smartphone is possible, and a teleassistance service ensures prompt intervention and continuous system monitoring.
