ARC Systems Highlights
Advanced Emergency Ventilation and Air Filtration Systems for Collective Protection and Safe Environment
Key Features:
-
The ARC series was developed by Arconik for use in residential shelters, small bunkers, safe rooms and other protected spaces.
-
The systems are tested, and all their components are certified for compliance with technical requirements of SI 4570 standard (Air ventilation and filtration systems for shelter and protected spaces).

*The shelter air volume and air change per hour (ACH) calculated according to one complete ACH. In some standards minimum two ACH is required.
In selection of the systems beside the parameter of air changes, other parameters should be taken into account like number of people in the shelter, national or local standard for air volume per person, additional components of the shelter like airlocks, generator rooms, air distribution and leakage.
We recommend to contact us for support in selecting the correct system for a specific shelter.

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.
