Safety cautions●For safety purposes, carefully read the instruction manual before use and properly maintain the system.
●This system is designed for initial ﬁre extinguishing. However, it may not be possible to extinguish a ﬁredepending on the type, size and form of combustible materials.
●The products listed in this catalog are components of ﬁre extinguishing systems.Do not use it for any other purposes.
●This product is diﬀerent from the ﬁre extinguishing equipment speciﬁed by the Fire Service Act.

Achieved high expansion foam
while sucking smoke.
This reduces smoke diffusion
and liabilities by smoke.

High expansion foaming is achieved even insmoke condition. Smoke is trapped in bubbles toprevent dispersion of smoke.
FeatureAchieved a foam expansion ratio of approximately 650 times by aspirator method
while aspirating smoke in the fire room.

Traditional high-expansion-foam fire extinguishers have disadvantage that foam expansion rate is remarkably reduced
because the generation of foams is inhibited by smoke and hot air flow of combustibles.

Smoke is trapped in bubbles to reduce the spread of smoke outside the fireextinguishing area.

As smoke is confined in foam and extinguished in a short period of time, the spread of smoke outside the fire extinguishing area
is extremely small compared with traditional fire extinguishing systems, making fire response and evacuation activities easier.

This system eliminates the need for air intakes and air outlets on the exterior walls of
the building, thereby reducing the overall cost of the facility.

Originally, wall penetration and building reinforcement work for the intake port that draws fresh air from the outside air and theexhaust port that does not increase the internal pressure are required, which not only increases the cost of the entire facility, butalso may not be installed depending on the building.

The inside air system and its thinner, smaller and lighter design make it possible toinstall the ceiling in a decentralized manner.

Since bubbles are formed by smoke in the fire room,no air intake and exhaust vents are required on the exterior wall.

This high expansion foam extinguishing system uses a special foam agent that does not reduce the foaming ratio even if
it aspirates the indoor air during combustion.Even if it aspirates smoke and hot air flow from petroleum and rubber fires,the foam expansion ratio is maintained at about 650 times.
