Ductless heat exchange ventilation fan with an outer diameter of 100Φ developed for Japanese housing.

At Komasho Co., Ltd., in addition to the "HEATTECH FAN," we provide comprehensive support for building safe, secure, and comfortable homes with systems such as the underfloor heating and cooling system "CCFSTYLE," the heat tech construction method (heat-insulating panel method), the SG method (guaranteed seismic isolation method), and the "Boric Acid De Anshin Guarantee" with a 20-year, 30 million yen termite warranty. *For more details, please feel free to contact us.

No need for termite prevention treatment every five years! A method that significantly extends the lifespan of important wooden houses.

**Four Characteristics of Boron Treatment** ■Termite Resistance ・Strongly suppresses damage from wood-deteriorating pests such as termites and wood-boring beetles. ■Preservative Properties ・Exhibits powerful effects against wood-decaying fungi and suppresses the growth of mold. ■Durability ・Effect lasts semi-permanently unless exposed to wet environments such as running water or in contact with the ground, as it does not volatilize or decompose. ・No need for re-treatment within five years, unlike conventional pesticide-based termite and preservative agents. ■Safety ・Does not volatilize, so it does not contaminate indoor air. ・In the unlikely event that a mammal with kidneys, including humans, ingests it, the impact is similar to that of table salt. *For more details, please refer to the catalog or feel free to contact us.*

Transforming air into a heat medium to simultaneously heat and cool the floor and indoor space! Efficiently circulating indoor air to create a comfortable living environment!

**Features** [Winter Mechanism] ○ Efficiently warms indoor air and circulates it throughout the house → The air collected by the indoor unit is efficiently heated using a heat pump system and sent to the underfloor chamber box. ○ Simultaneously warms the underfloor space and the entire floor surface → The warm air sent to the underfloor chamber box travels through the underfloor duct and is released into the underfloor space, warming both the underfloor area and the entire floor surface at the same time. ○ Comfortably heats the entire house from below → The air heated under the floor is released from the floor outlets installed in various locations, comfortably warming the entire house. [Summer Mechanism] ○ Dehumidifies and cools indoor air, efficiently circulating it throughout the house → The air collected by the indoor unit is efficiently cooled using a heat pump system and sent to the underfloor chamber box. ○ Dehumidifies the underfloor space and cools the entire house → The cool air sent to the underfloor chamber box travels through the underfloor duct and is released into the underfloor space, cooling both the underfloor area and the entire floor surface at the same time. ○ Gently cools the entire house from the ceiling in summer → The air from under the floor is blown out from the ceiling through the air chamber, gently cooling the entire house. ● For more details, please contact us or download the catalog.
