Pressurisation Systems For Access & Safe Evacuation

PRESSURISATION OF STAIRCASES: THE IMPORTANCE OF CORRECTLY SELECTING THE SYSTEM CLASS AND CONTROLLING THE DEGREE OF OVER PRESSURE A pressurisation system is intended to prevent smoke leaking through closed doors into stairs by injecting clean air into the stairwell. The intent is to have the highest pressure in the stairwell and a reducing pressure in the accommodation area to facilitate pedestrian escape route and firefighting access. Since the publication of the relevant standard, EN 12101-6, familiarity has increased along with understanding...


Biomass Applications: Selecting Industrial Fans

At Axair we’re familiar with supplying industrial fans for use within renewable energy generation and offer a range of fans specially designed for use in Biomass fuel applications. These fans range from low to high pressure including those for materials handling and high temperatures. The simplest Biomass heaters burn chipped Biomass materials such as wood, straw and elephant grass and use medium pressure blowers such as the Sodeca CMP, CMR and CMA ranges to provide combustion air. The energy produced can be used to heat water or air and...


All About Smoke Control

We've had a heavy focus on Smoke Control over the past year and have continually informed our audience about new legislation, new products and kept our technical knowledge in tip top shape. This week we thought what better time to recap on some of the top five questions we should know about Smoke Control. In the event of a fire, what are the main risks associated with Smoke? The main risks associated with smoke are; Toxicity; including lack of oxygen, inhalation of toxic gases and suffocating gases. Heat; including internal ...


Understanding ATEX Zones for Gas & Dust

This week we look at ATEX zones for gases and dust to dig a little deeper into ATEX understanding. If you are not sure whether you need an explosion proof ATEX fan or need to know the ATEX zone in which your application is classified, please consult an official authority in your country. ATEX is an acronym derived from the words “Atmospheres Explosibles” and forms part of a European equipment directive known as ATEX 2014-34 EU. The directive covers manufacturing standards and ensures that people are protected against the risk that may be...


Understanding Computational Fluid Dynamics (CFD)

This week we discuss how CFD can be used to specify effective smoke control solutions, What is CFD? Computational fluid dynamics (CFD) is the use of mathematics, physics and computational software to visualise how a material flows. It also looks at how the material affects objects as it flows past. Computational fluid dynamics is based on the Navier-Stokes equations. These equations describe how the velocity, pressure, temperature, and density of a moving fluid are related. Can you explain how Axair use CFD to help their clients? ...


Axair Fuel Fans For Efficient Biofuel Drying

With renewable energy sources on our mind, we recently posted a blog update around Biomass as an alternative to fossil fuels so now we’re delighted to be able to add another renewable energy biofuel source provider to our midst, improving our expertise and improving the carbon footprint of UK businesses. From our previous post here, you’ll be aware that Biomass technology is safe, clean, reliable and sustainable, and as an example, a company spending £15,000 on heating can save up to 70% on heating and 50% on fuel costs. With such signi...


Green Renewable Energy With Biomass Fuel Fans

  As the demand for an efficient form of renewable energy increases due to the ever decreasing volume of fossil fuels available, Biomass is now in the spotlight. Biomass energy is produced using the matter contained in plants, typically including wood chips, trees, manure, sewage and mulch. Due to the nature of the matter harnessed, the energy is classed as renewable as it can be regrown and used again. It’s good to note that Biomass energy sources don’t emit Co2 which means they limit the greenhouse effect by not polluting the at...


Unrivalled Technical Knowledge & Expertise Leads To CPD Success…

  It’s been almost five months since Axair Fans began offering CIBSE approved CPD seminar sessions in Mechanical Smoke Ventilation. Following a successful seminar held in September at HMS Belfast, London and after feedback from industry members, our capability has been extended to offering short hour long lunch time sessions held at client offices. This op tion allows attendees to maintain their CPD portfolios while staying up to date on Industry legislation, building an increased knowledge of Mechanical Smoke Ventilation and stairwell ...
