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 systems were approved for use by Civil Defence Command and installed in tens of thousands of shelters around the world.
Standard ARC system kit includes – blast valve, prefilter, electric blower, manual backup (optional), CBRN filter, air duct and hoses, noise silencer, overpressure valve/s.
The ARC systems models ARC 100, ARC 180, ARC 240, ARC 300, ARC 450 and ARC 600 have versions for floor and wall installations (what allows efficiently to maximize the floor space).
Simple Installation in new structures with pre-installed (cast in concrete) wall sleeves with 8-inch flanges or retrofit installation on existing walls with retrofit 8-inch flanges connected to the wall with concrete anchors.
Ready for use withing minutes and can be operated by one person.
The electric blower fan can be operated with 230 or 115 VAC. Additionally a manual backup device is available in versions up to 600 m3/h airflow for insuring continued operation of the system also in case of electric outage.

Applications:

Ideal for civil defence shelters, government bunkers, emergency shelters, and critical infrastructure requiring high-security air filtration and overpressure maintenance.

*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.
