Why use RDT 30?

Respiratory protective masks get exposed to a wide range of contaminants, such as dust, perspiration, bacteria and viruses, as well as dirt of all kinds. Hence, they need to be thoroughly cleaned and disinfected.

Cleaning and disinfecting respiratory protective masks manually is a time-consuming, and not entirely hygienic, process.The fully automatic mask washing machine RDT 30 allows for the gentle, hygienic and efficient back-to-back cleaning, disinfecting and drying of respiratory protective masks. If the washing machine is to be used in fields where masks get particularly heavily soiled, it can be programmed to perform an additional cleaning cycle. The soiled masks get screwed or snapped onto the take-up shafts’ mask holders via adapters, and the machine is started. Adapters with round threads, M45x3 threads and plug-in connectors are available for all common makes of positive-pressure masks (see accessories). After approximately 3.5 hours, the perfectly cleaned, disinfected, rinsed and dried masks can be taken out of the machine.

How RDT 30 works

In a fully automatic manner, RDT 30 controls the required amounts of water and draws them directly from the available water supply via its water connection. When RDT 30 is used in its basic configuration, the required amounts of disinfectant have to be added manually. Fully automatic disinfectant and detergent supply units are available as optional extras. The disinfectant/detergent is drawn from the reservoir by means of a pump, pressurized and sprayed onto and into the masks. As the masks are rotating, they get sprayed on all sides for perfect cleaning and disinfecting. The air for drying is heated to approximately 40 °C and blown directly into the masks via the take-up shafts and the mask adapters (forced ventilation). The rotation of the masks, which causes the residual water in them to spread evenly, and the stream of warm air reduce the drying time to a minimum. With RDT 30’s internal water heater, the detergent and disinfectant in the machine can be heated to a maximum of 30 °C. The wastewater is pumped off and discharged into the sewage system via the wastewater hose.
