Main features:
Constant wind speed technology eliminates the risk of low wind speed and weak negative pressure leakage caused by voltage fluctuations or increased resistance of HEPA (ULPA)
ULPA filtration technology achieves a filtration efficiency of over 99.999% for dust particles such as 0.1~0.2 μ m particles, smoke, and microorganisms
The total pressure of the fan is greater than twice the initial resistance of the filter, effectively extending the service life of the filter and reducing the operating cost of the equipment
Large screen LCD display monitors the entire process and displays actual parameters such as wind speed, pressure difference, air volume, and HEPA (ULPA) working status on the entire interface
Innovative internal safety negative pressure design, any leaking airflow will be surrounded and captured by the negative pressure system
ZHICHENG's unique sealing design features a stainless steel frame and door sealing sleeve coated with epoxy resin, ensuring that gas inside the cabinet will not leak under any circumstances
ULPA/HEPA operation status automatic detection function
ULPA/HEPA Failure Prevention and Alarm System
ULPA/HEPA Damage Alarm System
The independent low wind speed alarm and main control circuit form a dual alarm system and are interlocked with the fans inside the cabinet
Front window height exceeding limit sound and light alarm
Self diagnosis alarm and fan interlock action for supply and exhaust fan faults
Appointment disinfection function to improve work efficiency
Front window and disinfection lamp interlock design, protecting operators from accidental UV radiation
The visible front window is designed with a 10 ° tilt angle that meets ergonomic principles, effectively reducing glare over a wide range and making the operator more comfortable
Non reflective double-layer safety laminated glass, with good explosion-proof, shatter resistant, and UV resistant functions
A high-quality stainless steel operating surface that can be formed by movable stamping, sturdy, durable, and easy to clean
Power socket with splash protection cover and standard water and gas valves
Fluorescent lamps are installed outside the work area, free from pollution and easy to install
All can be vented indoors or outdoors through pipes.
Provide fully installed pipeline fittings
Application scope:
This device is widely used in research and application fields such as biopharmaceuticals, biochemistry, healthcare, environmental monitoring, and electronic instruments and meters.
Supplementary explanation for industry applications:
It is designed to protect the operator, laboratory environment, and experimental materials from exposure to infectious aerosols and splashes that may occur during the operation of infectious experimental materials such as primary cultures, bacterial strains, and diagnostic specimens.
