The ventilation system is proving very effective at maintaining excellent air quality in the Ivy House bar, irrespective of the number of smokers. We are particularly impressed with the ability of the unit to prevent cigarette smoke from reaching the bar staff. This enabled us to improve the working conditions of our staff by removing passive smoking, whilst still allowing our customers the traditional opportunity to smoke whilst sitting at the bar.

These benefits, together with the energy conservation measures such as PIR activation and use of a heat exchanger, provide a very efficient solution to how to cater for both smokers and non smokers in a single bar.
