Dimensions and Installation Options

Option I - 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.

Option II - Installation Beside the Air Inlet 

​​​

  1. Blast valve is installed beside the decorative case with SAFE 360 components (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 (see below).

​

* Installation in this option is possible both with suitable precast wall sleeves and retrofit flanges which is below, leveled or on the wall surface.

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.
