Since the beginning of 2020, the coronavirus (SARS-CoV-2) pneumonia epidemic that has rapidly swept the world to the present has made the topic of infectious disease prevention and control continue to be highly valued. As we all know, the transmission of pneumonia virus mainly has different forms such as droplet transmission and aerosol transmission. For the highly contagious coronavirus, negative pressure isolation in the hospital can effectively control the source of infection and cut off the route of transmission. On this premise, in accordance with GB/T 35428-2017 hospital negative pressure isolation ward environmental control requirements, MayAir as a professional clean air equipment manufacturer and service provider, provides negative pressure isolation air purification equipment, such as: outdoor exhaust Air filter unit EFB, indoor exhaust air purification device EHU, ultra-thin negative pressure clean screen UCP, HEPA purification unit for isolation stretcher, mobile clean trolley Case Cart, HEPA purification unit for personal anti-infection mask, vehicle-mounted fresh air exhaust The unit is adapted to the rapid transformation of negative pressure isolation wards and the needs of a variety of normalized epidemic prevention and control applications.

　　NO.01

　　Exhaust Air Filter Unit EFB

The exhaust filter unit is composed of a box body, an exhaust fan, a filter and a control part; the box body is composed of a frame + a heat preservation box board, which has good thermal insulation performance and mechanical strength, and good corrosion resistance; the exhaust fan air volume is infinitely adjusted; The filter can be used in combination with primary filter, medium-efficiency or activated carbon filter, high-efficiency or antibacterial filter according to the use environment. This product is widely used in various air conditioning and ventilation systems with its advantages of energy saving, small size, intelligence, and low noise.

Applications

Comprehensive hospitals transform infectious disease areas, field hospitals build clean spaces, shelter hospitals isolate treatment areas, core areas of pharmaceutical factories where negative pressure is required, and CDC laboratories.

　　NO.02

　　Indoor Exhaust Air Purification Unit EHU

EHU is used for installation in existing wards without ventilation. Part of the indoor circulation can effectively adsorb the bacteria-carrying particles in the room, and a small part of the external ventilation can make the room negative pressure while making the discharged air sterile.

The indoor exhaust air purification device uses the filtering principle of primary filter + sterilization efficiency + fan. The front-end primary filter filters large particles of dust or flying hair; the efficiency of the sterilization HEPA filter is 99.99%@0.3um, the dust holding capacity is high, and the filter can be effectively filtered. Small particles of germs and microorganisms, and maintain effective bactericidal ability.

Applications

Placed in a ward that needs to be temporarily changed to a negative pressure isolation area.

　　NO.03

　Ultra-Thin Clean Panel

The ultra-thin clean panel has good dust removal, odor removal, harmful gas removal, and antibacterial functions, and has significant adsorption and filtration functions for polluting gases. The cleanliness of the air outlet of the air cleaning screen can reach class 100. It can easily achieve dust-free and sterile local space in a short time, and keep harmful bacteria and polluted air away from indoor personnel. The clean panel is composed of a fan, an air duct, and a purified air filter. The ultra-thin clean panel has a thinner body thickness, a simple and beautiful appearance, saves installation space, is convenient to install, and is suitable for indoor air purification places.

Applications

Clean panel are often used in occasions that require air purification, sterilization, and deodorization: hospitals (negative pressure isolation beds), electronics factories, pharmaceutical manufacturing, sterile rooms, laboratories, changing rooms, growing point cultivation, breeding, sterile animals , Electronic parts assembly, household, public use, etc.

　　HEPA Purification unit for Negative Pressure Isolation Stretcher

The HEPA Purification Unit (HEPA Purification Unit) can switch between negative pressure and positive pressure. The HEPA purification unit and the isolation soft cover can be used in conjunction with an ambulance stretcher to form a negative pressure isolation stretcher, which can isolate the source of infection, cut off the transmission route, and reduce the risk of infecting medical staff during patient transfer.

Applications

HEPA purification unit can be used in pharmaceutical factories/medical clean trolleys, isolation stretchers, protective masks, simple clean operation boxes, etc. At the same time, the purification unit can switch between positive and negative pressure.

HEPA purification unit and isolation soft cover (available as a complete set) can be uses to different negative pressure isolation cabins, negative pressure isolation stretchers and other equipment.

　　NO.05

　　洁净手推车(Case Cart)

Case Cart is used for transportation of items in hospitals, laboratories and other places. It is composed of fans, HEPA filters, batteries, cabinets, etc., which can establish and maintain the pressure difference between the inside and outside of the trolley box. There are two working modes of positive pressure and negative pressure during work: When transporting pollution sources in the car, the negative pressure mode can be used to prevent pollutants from spreading to the outside; when the car is loaded with clean items, the positive pressure mode can be used to prevent external pollutants from entering the car.

This product can effectively reduce the transport pollution between the transported goods and the external environment, intercept and adsorb harmful substances such as dust or bacteria, and improve work efficiency.

Applications

Case cart are often used in places where transport pollution needs to be controlled: wards, operating rooms, pharmaceutical manufacturing, laboratories, electronics factories, etc.

　　NO.06

　　HEPA Purification Unit for Personal Anti-pollution Masks

HEPA purification unit for personal anti-pollution masks is also known as powered air purifying respirator (PAPR). Unlike traditional non-woven masks, this equipment uses a HEPA filter, and the HEPA purification unit is used for air supply or exhaust. The sealed hood is connected and used to realize the personal air purification protection function. And by changing the position of the pipe connection port, the positive/negative pressure inside the mask can be switched.

Applications

Personal anti-pollution purification masks are widely used in the medical industry, special places in pharmaceutical factories, and industries with more industrial dust particles.

　　NO.07

　　Fresh And Exhaust Air System For Car

Fresh And Exhaust Air System For Car is composed of three parts: exhaust system, fresh air system, and control unit. The outside atmosphere is filtered by the HEPA filter in the fresh air blower, and then clean air is sent into the car; the harmful gas exhaled by the patient in the car is efficiently filtered and sterilized by the ultraviolet lamp in the exhaust fan, and then the clean air is discharged to the outside of the car. Protect outsiders or the environment from pollution. At the same time, it can automatically control the 16m³ car space to reach a negative pressure of -10Pa~-25Pa, or a positive pressure of +10pa~+25pa.

Applications

Fresh and Exhaust Air System for Car are widely used in applications. Common ones can be applied to related equipment such as negative pressure ambulances, mobile nucleic acid sampling workstations, and on-board PCR laboratories.
