Aerial disinfection of small volumes safety hood

Aerial disinfection device for very small volumes (such as PSM, clean and safety room, SAS, laboratory, etc.) allowing the diffusion, via a pump and a rotating disk, of a disinfection product such as H2O2 or any other compatible products (contact us). The volume will then be disinfected by misting without leaving traces of humidity or condensation, ideal for example for the decontamination of Microbiological Safety Stations / ETRAF / Laminar flow hood

Nebulization device with electronic card

Autonomous disinfection unit operating on mains, battery (Option) or in electrical protocol via dry contact.

Description

Decontamination of PSM hoods and very small volumes

An MSP, or Microbiological Security Post, refers to collective protection equipment to prevent airborne contamination in laboratories. Specifically, it is a ventilated enclosure with very high air efficiency filtration to protect both the environment and the user when handling potentially dangerous biological pathogens.

The frequency needed to do decontamination

EN 12469 has been in effect since January1first, 2003, recommending that regular decontamination of accessible and inaccessible MSP surfaces must be carried out:

  • Before carrying out any type of maintenance
  • Before changing the filters
  • Before moving
  • Before the waste dump
  • After changing activity
  • After noticing the presence of contamination

The standard EN 12469 is available in NF- EN 12469 in France; BS-EN 12469 in Great Britain; TUV-EN12469 in Germany.

Different types of MSPs

EN 12469 classifies MSPs into three types, based on the technological means implemented and the levels of protection provided.

PSM Type I

The PSM Type I only protects the user, i.e. it does not allow the protection of the products handled. The operator is protected by the creation of an airflow that will enter the enclosure open on the front and it is evacuated into the atmosphere after it passes through a very high efficiency HEPA filter.

PSM Type II

Type II MSPs protect both the user, the atmosphere and the manipulated product.

The protection of the user is carried out by an aspiration created on the front of the worktop forming a barrier between the operator and the manipulated product.

As for the protection of the atmosphere, this is done by evacuating the airflow outside the enclosure through a very high efficiency filter.

As for the protection of the manipulated product from contamination, this is done by the vertical one-way flow of filtered air. Dedicated equipment allows the flow to be programmed so that the filtered air flow is directed to the manipulated product.

PSM Type III

At the same time, the Type III MSPs provide operator and atmosphere protection but do not provide special protection of the product from cross-contamination due to the lack of one-way airflow in the enclosure.

The operator is protected by the creation of a volume of work in depression having no direct opening to the laboratory and the product by feeding the enclosure in air through a filter with very high efficiency.

The atmosphere is protected by the evacuation of the airflow outside the enclosure through two filters with very high efficiency, installed in series.

Our MSP decontamination devices

To decontaminate and disinfect MSPs, Ecosprayer offers effective devices, in particular:

  • Aerial disinfection of small volumes Airborne surface disinfection by dry spray

It is the smallest nebulizer, specially designed to disinfect small surfaces of less than 40 M3 such as: psm, isolators, fume hoods, ambulances, animal cabinets, small laboratory rooms, cupboards, hoods, etc.

The intuitive and ergonomic interface meets routine needs but also more specific quality requirements (management of profiles, traceability and complete cycles). Protocol generation is robust and extraction via USB is very practical.
Its integrated DeFAN aeraulic management system ensures particle homogeneity in complex volumes.
