Shelters & Protective Technologies

SAFE 360

CBRN Filtration & Ventilation System for Small Size Shelters, Bunkers and Safe Rooms

SAFE 360 is an advanced, compact and certified CBRN (Chemical, Biological, Radiological and Nuclear) air filtration and ventilation system especially designed for installation in small size protected spaces like safe rooms, residential shelters, bunkers, containers and more for providing fresh filtered air and creating protected environment in the intended area.

​

  • All components of SAFE 360 are tested and certified according to SI 4570 and approved for use by national authorities

  • Installed in tens of thousands of shelters worldwide

SAFE 360 Overview

SAFE 360 Main Specifications

  • Nominal airflow in filtration mode: 36 m3/h (CMH)

  • Nominal airflow in ventilation mode: 54 m3/h (CMH)

  • Electrical requirements: 100-230V AC (one phase) / 12 V DC (optional)

  • Manual backup included for continues operation of the system also in cases of electric outage.

  • Variants: floor-free (wall/hidden) installation

  • Recommended max. shelter size per system: 36 m3. Several systems can be installed in the shelter/facility.

Key Features:

  • All SAFE 360 system components are is tested and certified for compliance with technical requirements of SI 4570 standard (Air ventilation and filtration systems for shelter and protected spaces).

  • SAFE 360 systems were approved for use by Civil Defence Command and installed in tens of thousands of shelters around the world.

  • Standard SAFE 360 kit includes blast valve with prefilter (for air inlet), electric blower, manual backup device, CBRN filter, overpressure valve with airflow indicator, air hoses and connectors, decorative case.

  • SAFE 360 systems can be installed both in new spaces and retrofitted into existing spaces.

  • SAFE 360 is simple to use and can be ready for operation withing minutes by a single person.

Dimensions & Installation Options

Option I - Installation Aside of the Air Inlet 

  1. Blast valve installed near other SAFE 360 components which are located under the decorative cover (beside the overpressure valve).

  2. Overpressure valve should be located away of the main unit for effective air distribution.

  3. The installation of blast valve and overpressure valve should be made on preinstalled 4-inch flanges or wall sleeve (see below).

* Installation in this option is possible only on suitable flanges which are below, leveled or on the wall surface. 

Option II - Installation on the Air Inlet 

  1. Blast valve and other SAFE 360 components (beside the overpressure valve) are located under the decorative cover.

  2. Overpressure valve should be located away of the main unit for effective air distribution.

  3. The installation of blast valve and overpressure valve should be made on preinstalled 4-inch flanges (see below).

* Installation in this option is possible only on suitable flanges which are below or leveled with the wall surface. Installation with retrofit flange is only possible in case it is installed in a niche.

Preparation for Installation

Definitions:

  • Air inlet – ventilation opening in the shelter perimeter wall intended for pulling fresh air from outside.

  • Air outlet – ventilation opening in the shelter perimeter wall intended for releasing air from the shelter.

  • Blast valve – a protective device designed for installation on/in the air inlet for protecting the internal space and the system components from blast wave pressure.

  • Overpressure valve – a protective device designed for installation on/in the air outlet for controlled release of air from the shelter and maintenance of overpressure levels in the protected space.

  • Flange – devices for connection of air duct or valves.

​

Prior installation it is recommended to perform a pressure/gas tightness test to identify and treat the air leakage sources from the shelter perimeter. For proper operation of the system and creation of overpressure (positive differential pressure) inside, the shelter has to be airtight.
 

Overpressure helps to prevent penetration of contamination through small cracks or opening in the shelter perimeter.

Wall Sleeve with Flange

Wall sleeves are hollow pipes which are intended to be casted in shelter concrete walls for allowing passage of air from outside and inside. Wall sleeves are usually connected with flanges on the shelter side to allow simple connection of the blast valve, overpressure valve, gas tight valve, air duct, cable gas tight passages and more.​​

* wall sleeves are not included in the SAFE 360 kit and can be purchased separately.

Retrofit Flange​

Retrofit flanges designed to allow connection of the blast valves and overpressure valves to existing walls in the perimeter of the shelter/ protected space. The flanges connected to the wall by special concrete anchors and have pre installed bolts for securing the valves with nuts.

* retrofit flanges are not included in the SAFE 360 kit and can be purchased separately.
