UK fan manufacturer Elta Fans has supplied ventilation equipment for the highly sustainable and awardwinning headquarters of The Co-operative Group in Manchester. 'One Angel Square' has received several awards for its striking aesthetics and is the most sustainable large office space in Europe. The building has been designed to deliver a 50% reduction in energy consumption compared to The Co-operative's current Manchester complex and an 80% reduction in carbon. This will lead to a reduction in operating costs of up to 30%.

The Edinburgh International Book Festival first began in 1983 and this year took place from 10-26 August. From humble beginnings, it has grown in both size and scope to become the largest and most dynamic public celebration of the written word. Originally staged every two years, it is now a key event in the city's annual 'Festival' season where authors and readers come together to discuss the day's pressing literary issues and is enjoyed every year by thousands of people of all ages. Throughout its 30 year history, the Book Festival's home has been the beautiful and historic Charlotte Square Gardens, just a minute's walk from the famous Princes Street. Every year a tented village of marquees covers the leafy gardens to accommodate all the various discussion groups, meetings and events.

The SLC710 is just one model from Elta Fans 'Revolution' range of long cased axial fans. Robust and heavy duty, they are housed in hot dipped steel casings, which are welded and then galvanised after fabrication to BS 729 for even greater strength and durability. The casings have integral spun flanges to allow for a smooth flow of air.

The fans are fitted with adjustable pitch, aerofoil section bladed impellers made from high quality, pressure die cast aluminium. Fan hubs are also made of die cast aluminium. These high efficiency impellers make the fans an economical means of moving very high volumes of air at low to medium pressure. The angle of pitch of the impeller can be adjusted on site. An industrial workhorse, this Elta model offers good performance, ease of installation and a full accessory range, together with corrosion resistance for a longer life. All models are suitable for both internal and external use.

The Revolution SLC was thus a sensible and practical choice for preventing the build up of hot air within the marquee during any warm days of the 17 day event, or indeed to circulate any warmth generated in the event of a change in the weather!

Elta Fans is part of the £90 million Elta Group, a family of businesses with operations in six countries on four continents which, together with a network of international distributors, provides quality fans and related air movement equipment to customers worldwide.
