DF-A5-Dry fog hydrogen peroxide sterilizer

Meizhuo DF-350-A5 series dry-mist hydrogen peroxide sterilization system can continuously supply disinfectant with a low-speed liquid pump and supply high-kinetic-energy carrier gas though an ultra-high-speed fan. When the small amount of liquid enters the nozzle at a low speed and encounters the high-speed carrier gas, the gas will fiercely collide with the liquid and crush it. The air enters the nozzle in a porous eccentric way to adjust the centrifugal rotation, which increases the distance and strength of the collision between the gas and the liquid and makes the liquid torn by the gas in a fiercer manner so as to achieve the effect of submicron atomization. After that, the submicron particles are quickly transported to the far end and spread perfectly to the entire space with the strong power of the ultra-high-speed fan, thereby achieving highly efficient sterilization.

Application case

Meizhuo DF-350-A5 series achieves Log6 level of disinfection and sterilization by employing low-concentration hydrogen peroxide or other disinfectants, which is able to quickly kill viruses, fungi, molds, spores and other microorganisms in the air and on the surface of objects within the sterilized area. Using only a few milliliters of low-concentration hydrogen peroxide per cubic meter and causing a little rise of ambient humidity, it leaves no corrosive effect on instruments, computers, metal products and other stuff in the environment. It is convenient and rapid in the whole course of disinfection and sterilization as without the need for heating, neutralization and other processes.

We have shared common questions from customers and hope to help you, of course you can contact us at any time.

Is the bottle refillable?2020-06-30T10:17:28+08:00

Yep, it's refillable.

What's the droplet size?2020-06-30T10:16:49+08:00

7.5um or 1-5um(Laboratory testing data)

Can the liquid only use hydrogen peroxide?2020-06-30T10:15:55+08:00

Theoretically speaking, you can use any liquid you like. However, for best sterilization effect, we suggest 6-8% H2O2 and recommended unit volume 6-8ml/m3.

Are your equipments sold with the solution together?2020-06-30T10:15:15+08:00

No, we just export devices, not including the disinfectant. It's really easy for you to get H2O2 locally.

What's the application of your devices?2020-06-30T10:14:37+08:00

Our devices are mainly used in medical field, such as negative pressure wards, isolation wards, emergency ambulance, ICU, clinic and etc. Our devices using 6-8% H2O2 to achieve Log6 level sterilization rate, which can quickly kill microorganisms such as viruses, fungi, molds and bacillus in the air and the surface of the sterilization area.

Will it cause damage to the objects in the room?2020-06-30T10:13:39+08:00

Generally speaking, it won't cuase any damage. Our disinfectant is at low concentration 6-8%, it has no corrosive effect on the instruments, computers, metal products in the environment?

How can I know the sterilization effect after using?2020-06-30T10:12:41+08:00

We can send the domestic test report to you. Or you can buy indicator strips together, BI(Biological indicator): ATCC12980 or ATCC7953 or CI (Chemical indicator)

Is your device classified to medical equipment?2020-07-02T08:21:05+08:00

It doesn't belong to medical equipment in China, belong to disinfection equipment, but mainly used in medical fields.

DHP Versus VHP2020-06-30T10:08:37+08:00

DHP has better diffusion effect while VHP with vapor spray can disperses more evenly.
