“LIFE JUMP AIR PACK 70 A” consists of three basic elements: n. 2 fans and n. 1 inflatable cushion.
It is easy to use, the inflation itself needs just the two fans turned; it is about 2,40 meters high and has a surface area of 27m² .
The cushion is composed of a lower chamber, an upper chamber where there is a safety valve for overpressure, and two delivery hoses. The elements part of the cushion are sewn and welded in advance in order to allow an easy and fast use of the equipment.
Three operators are enough to prepare the cushion in about 5 minutes.
The jumping cushion can be assembled at sites that pose access problems, courtyards of buildings, narrow streets, stairs or even on the roofs of parked cars.
The two helical electric fans provided are perfectly suited for use with the cushion; they have IP 55 motors, are supplied with 15 m self-extinguishing connecting cables, plugs according to the CE IP 67 norm and can be powered either from the mains or by the generators normally supplied on vehicles in use in National Fire Brigades. The fans can even be used in rainy conditions.
LIFE JUMP AIR PACK acts as energy dissipator of falling bodies. The vents on the side of the cushion release air at impact on its surface, absorbing without rebounds a falling body on it. LIFE JUMP AIR PACK absorbing capacity is expressed in 1/6 of a second, so the air path and the vents openings have to work freely. LIFE JUMP AIR PACK is composed of two compartments (chambers) separated by a panel. The upper chamber has n. 4 vents, which dissipate in an optimal way the falling energy of a body, completely eliminating trampoline effect. Special ropes regulate the outlet flow according to the falling height and the supposed weight of the person to save.
The lower chamber absorbs the excess of energy of the falling body avoiding it reaches the ground. Such chamber acts as a safety compartment and it has an absorbing capacity twice greater than the upper chamber. The base of the lower chamber is made of more resistant to wear and rubbing material.
