Spray disinfection air shower, as a dedicated device integrating air purification and spray disinfection functions, is widely used in places with extremely high requirements for cleanliness and sterility (such as pharmaceutical workshops, food processing plants, biological laboratories, etc.). Its features are mainly reflected in multiple aspects such as disinfection efficiency, degree of automation, and applicability, as follows:
1. Double purification, more thorough disinfection
The most distinctive feature of the spray disinfection air shower is that it combines the dual functions of physical dust removal and chemical disinfection, achieving an integrated process of “decontamination + sterilization”.
Physical air shower dust removal: By using high-speed clean air flow (wind speed 20-30m/s), it blows off the floating dust, hair, dander, and other particles on the surface of personnel’s clothes and items, reducing the introduction of physical pollutants into the clean area.
Chemical spray disinfection: Disinfectants (such as hydrogen peroxide, hypochlorous acid, etc.) are atomized into tiny droplets (5-50μm), evenly covering the surface of the object to be disinfected. By destroying the cell membranes, proteins, or nucleic acids of microorganisms, it kills pathogenic microorganisms such as bacteria, viruses, and fungi, solving the problem that simple air spray cannot sterilize.
The combination of the two can more comprehensively reduce the risk of contamination in clean areas compared to traditional air showers (only for dust removal) or single spray disinfection equipment (only for sterilization).
Second, it operates automatically and is easy to operate
Intelligent induction start-up: Equipped with infrared sensors, photoelectric switches, and other devices, the disinfection program is automatically triggered after personnel or items enter, eliminating the need for manual operation and reducing cross-contamination.
Programmed control: Parameters such as disinfection time (10-60 seconds), air shower duration, and ventilation replacement time can be preset. The entire process automatically follows the sequence of “door closing → air shower → spray → ventilation → door opening”, avoiding human operational errors.
Status monitoring and Alarm: Some devices are equipped with display screens to show the real-time operating status (such as remaining time, disinfectant balance). When situations such as the door not being closed tightly, filter failure, or insufficient disinfectant occur, automatic alarm prompts will be given to ensure the stable operation of the equipment.
Third, disinfection coverage is comprehensive with no blind spots.
Multi-directional spray design: Inside the cavity (top, sides, bottom), multiple atomizing nozzles are usually distributed to form a 360° three-dimensional spray space, ensuring that the disinfectant droplets cover the entire body of the person (including clothing folds, shoe soles, hands) and all surfaces of the items, avoiding the dead corners problem of traditional disinfection (such as wiping, spraying).
Fine atomized particles: Through high-pressure pumps or ultrasonic atomization technology, disinfectants are transformed into micron-sized droplets, which can penetrate the fibers of clothes and the crevices of items, fully contacting with microorganisms and enhancing the disinfection effect.
Fourth, it has strong adaptability and can flexibly meet the needs of various scenarios.
Disinfectant options: Different types of disinfectants can be selected according to industry requirements (for example, hypochlorous acid is commonly used in the food industry, and hydrogen peroxide is commonly used in the pharmaceutical industry), with strong compatibility.
Adjustable specifications: The equipment size can be customized according to actual needs (such as single-person single-blow, double-person double-blow, and dedicated to goods), adapting to different channel Spaces.
Environmental compatibility: High-temperature and moisture-resistant design (for some models), it can operate stably in special environments such as clean workshops, sterile rooms, and cold storage.
Five. Balancing safety and environmental protection
Residue control: After disinfection, ventilation and replacement are carried out through high-efficiency filtered clean air (usually for 30 seconds to 2 minutes) to reduce the irritation of disinfectant residues to the respiratory tract of personnel or the corrosion of items.
Material safety: The interior of the cavity is mostly made of stainless steel (such as 304 stainless steel), which is resistant to disinfectant corrosion, easy to clean, and meets the hygiene standards of the food and pharmaceutical industries.
Leak-proof design: During operation, the inlet and outlet doors are automatically locked, and the cavity is sealed to prevent the leakage of disinfectant droplets and contamination of the external environment, while also preventing undisinfected air from flowing into the clean area.
Six. High efficiency and energy conservation, reducing operating costs
Circulating air design: The air in the air shower section is filtered and circulated through primary and high-efficiency filters to reduce the amount of fresh air introduced and lower energy consumption.
Precise control: The spray volume and air shower intensity can be adjusted as needed to avoid waste of disinfectants and energy.
Low maintenance cost: Core components, such as filters and nozzles, have a long service life, are easy to replace, and reduce downtime for maintenance.
In conclusion, the spray disinfection air shower room, with its features of “high efficiency, intelligence, comprehensiveness, and safety”, has become a key protective device at the entrance of clean environments, effectively ensuring the hygiene and safety of production, experiments, and other scenarios.
