Xi'an Longtai Building System Engineering Co., Ltd.

Xi'an Longtai Building System Engineering Co., Ltd. is one of the earliest and more prominent service enterprises in the northwest region engaged in central ventilation system projects. The company integrates technical services, construction design, project implementation, and product sales, specializing in building ventilation and air exchange engineering services. Since its establishment, the company has gained support and trust from various users and has established good long-term cooperation with many international famous companies. In terms of new air system applications, we have cooperated with Brown BLLC Limited, Enco Finland, Panasonic Environmental Systems Co., Ltd., and Thorne Environmental Technology (Shanghai) Co., Ltd. A new air system ensures that there is sufficient fresh air indoors even when windows are not opened for 24 hours. It introduces fresh air from outdoors and exhausts indoor air containing harmful substances such as formaldehyde, benzene, and ammonia through physical principles, ensuring thorough air exchange between the outdoor and indoor environments. This system provides the fresh air needed for human health without affecting indoor temperature. The new air entering the room is slightly cooler than the room temperature, settles at the bottom of the room, and surrounds the body, completely separating from the warmer, polluted indoor air. All the incoming air comes from fresh outdoor air, while the indoor return air is uniformly discharged to the outside through dedicated exhaust ducts. In response to the heavily polluted haze weather, the company has introduced the PM2.5 series purification fan. This product features an outward rotor motor with a backward curved impeller and an internally self-lubricating bearing. It includes a multi-stage filtration system with intermediate and high-efficiency filters and activated carbon, capable of filtering over 90% of particles above PM2.5 and over 75% of particles below PM2.5. The activated carbon filter can adsorb volatile harmful gases and remove odors from the air. Due to business development needs, the company welcomes individuals with aspirations to join and work together to develop and innovate for a bright future.
