Introducing a new self-contained mechanical extraction system for postfire situations, SPI (Fire Engineering) the specialist gas extinguishing system installations company, has launched Ventpac as a complementary product to its portfolio of services in the dedicated area of fire engineering.
Supplied in a compact unit of just over 600 mm long, 360 mm wide and 460 mm high, Ventpac is designed to provide efficient extraction following a discharge of an extinguishant, or for the removal of post-fire atmosphere. This ensures that the fire brigade can venture into an area with confidence following a suppressed fire and that personnel in other parts of the building will be unaffected as a result of the system's operation.
Providing a minimum of four air changes per hour for enclosures of up to 250 m2 with or without voids, Ventpac is equally effective for halon, FE-13, FM200, inert gases and other suppression agents. It also draws air from floor voids for low level extraction assurance.
David Adkins, Commercial Director of SPI said: "In meeting BFPSA and british standards directives without the need to install a specialist engineered system, Ventpac achieves a balance between a fast and efficient ventilation and an extract system, in a single compact unit".
While the costs associated with individual ducting systems are high, the introduction of Ventpac as the latest development in extraction means that covering the same area is now possible for less than one third of the cost of conventional solutions.
Contained within a Zintex metal enclosure, Ventpac houses a high airflow centrifugal fan and positive shutoff damper with motor which are both very quiet in operation. Room atmosphere is extracted through a louvred grille positioned in the end plate to the outside of the building. The unit is pre-wired to allow actuation from the external system control panel or a fireman's switch.
Ventpac is extremely easy to install, requiring only a 250 mm diameter aperture. Complete with telescopic transition duct, it automatically allows for external walls of various thickness without the need for specialist site fitting work.
