Medium Pressure Centrifugal Fans: Backward Curved Benefits

What is a backward curved centrifugal fan? The backward curved centrifugal fan design uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is known as the fan wheel, and often includes other components with aerodynamic or structural functions. The centrifugal fan wheel is typically contained within a scroll-shaped fan housing. How does a backward curved centrifugal fan work? Backward cu...


Ventilation & Energy Efficiency For Powder Control

Clean rooms are vital when it comes to ensuring medicines are contamination free. Investing in new technology in addition to adopting hygienic handling techniques are paramount to effective clean rooms. Not forgetting air ducts and ventilation areas to facilitate the airflow and pressure required to ensure the required number of air changes per house and pressurisation of contaminants. Designers must dedicate time to designing clean rooms and equipment located within them. Modern clean room designs use computer aided engineering programs such a...

The Benefits of Warehouse Ventilation

For businesses with a warehouse, ensuring that it is well ventilated is vital. The main reason is the risk to the health of the employees. Not only will it affect health, but it will also affect the productivity of the employees, the equipment, goods and energy bills. In order to run an efficient warehouse, ventilation must be carefully considered. Axair were asked to supply a local engineering firm with several plate axial fans for their large warehouse. The company then visited the warehouse to gather some feedback. The product engineers a...


Industrial Fans For Food Processing & Manufacturing

The food processing industry is big business. With new processes, new packaging and more competition there’s added pressure on operations teams to implement the most efficient and cost effective method of manufacturing at every step in the production line. Like many industries, the food processing industry involves a huge array of processes connected to the final end product. Taking a raw material to a finished product ready to be shipped is an important part of manufacturing. This means that the highest standards of food hygiene must be a...


Axair Fuel Fans For Efficient, Clean & Safe 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...


AHU Refurb | As Easy As Childs Play

The refurbishment of existing air handling equipment is a practical alternative to replacing with a whole new system, benefiting from cost effectiveness, less disruption, more flexibility and the ability to improve existing specifications. During any AHU refurb all fan types can be replaced with the latest energy efficient fans with either the option of EC motor with on-board controls or traditional fan motor and inverter combinations. For example replacing old forward curved fans with backward curved plug fans can reduce energy consumption...


Inland Revenue Pay Attention To AC Fans…

Back in 1994, when Axair was in its early start up days, began the transformation of a brownfield site for use by The Inland Revenue to create office accommodation space for 1,800 staff. The development consisted of seven separate buildings, in the form of courtyards and L-shaped blocks which overlooked Nottingham Castle The office buildings were extensively pre-fabricated and what is now known as The Inland Revenue Centre, was a pioneering sustainable project in the UK. At night the inherent thermal mass of the concrete is exploited and pu...
