Automatic opening Vents (AOVs)

What Is A Smoke Vent System ?

Smoke and heat exhaust ventilation systems, also known as “SHEVS” are natural or powered systems to remove smoke from a building allowing low level escape routes to be kept clear of smoke and reducing damage to the building.

Types Of Automatic Vent Systems

Smoke Ventilation Systems

Smoke Ventilation Systems by AK Fire provide life Safety smoke ventilation systems that assist occupant’s means of escape and provide clear access for firefighting services. Based just outside of London, in Watford, Ak Fire are leading industry specialists in the supply, installation and maintenance of cutting edge, smoke venting systems, with a uniquely effective approach. From Natural Smoke Ventilation Systems to Mechanical smoke ventilation systems AK Fire has system and approach to suit every requirement

Natural smoke ventilation systems

Remain pleasing to the architect’s aesthetic vision, while offering maximum floor space efficiency and cost savings. From initial design, through installation, to commissioning and ongoing servicing, it is a total solution that offers hassle-free handover, testing and maintenance – as a standalone system or as part of an integrated fire safety approach. AK Fire has solution to suit you In the event of a fire, natural venting systems open air ways, using natural air flow dynamics to remove smoke, which is arguably the biggest threat to life. This can be attained by opening windows or vents, an automatic opening vent (AOV) or, where there is no external wall, a vertical smoke shaft.

Mechanical Smoke Ventilation systems

Can aid the safe escape of occupants’ and allow adequate access for firefighters. Our Mechanical Smoke Ventilation Systems are an alternative method to Natural Smoke Venting. In the event of a fire, mechanical smoke vent systems offer the ultimate in smoke control as they remove smoke from the building, thus aiding the occupants’ means of escape and providing suitable access for firefighting services. This type of smoke extraction system comprises of a mechanical extract shaft that serves the common corridor and/ or lobby. When smoke it detected within a protected lobby, only the fire damper to the smoke shaft on the fire floor will open (all other dampers will remain locked shut). In turn, the vent at the head of the staircase will open allowing the smoke to be removed and make up air for the smoke extraction system. The fan at the top of the mechanical smoke shaft extracts the smoke and prevents migration of smoke into the adjacent compartments.

AK Fire provide a complete smoke Vent systems for our clients including design, supply, installation, commissioning and maintenance of mechanical smoke vent systems. We work with clients across a wide spectrum of requirements from component parts of individual systems right through to value engineered innovative design and install solutions for large-scale mixed-use building projects.

Proven Solution

At AK Fire we design the Corridor Environmental System to maximise heat removal, providing occupants and maintenance operatives with comfortable internal temperatures. We can help you achieve substantial cost savings wherever we can utilise the smoke shaft during the initial construction stage, thus allowing us to complete installation in just one exercise. Our system has a proven track record of eliminating heat gain from the common heating/hot water pipework and allows the common stairway to be cooled. It also factors in the scheme’s acoustic requirements, with primary and secondary attenuation included in each system to minimise noise breakout. Not only can our specialist design team integrate our Corridor Environmental System with our mechanical smoke ventilation system for maximum cost and area efficiency, but we can also retrofit the system easily to existing smoke ventilation systems, avoiding costly additional installations.
