There's a lot of money in pure air

Reduce energy costs with Viledon

The words „saving energy“ are on everyone’s lips nowadays. Prices for the fossil fuels gas and oil have more than doubled since 2000. And consequently the electricity prices in the European Union have increased by about 30 % (source: Eurostat). But there are also major potentials for savings in areas where at first sight no one would expect them: 20 % of the electricity used in industrial and commercial applications is in fact used to operate fans and indoor climate control (HVAC) systems. 

Energy consumption by ventilation and air-conditioning equipment totals 40 % of the total energy requirement in office buildings, and in cleanrooms as much as 80 %. A substantial proportion of the energy consumed by HVAC systems is attributable to their pressure drops; air filters can account for up to 50 % of the total pressure drops in HVAC systems.

The fan in an HVAC system consumes electrical energy during operation, for example, to overcome the filter’s resistance. In the case of variablespeed fans, energy consumption will continually increase as a result of the air filters’ pressure drop. Many conventional filters display unfavourable resistance behaviour. Here, acting sustainably means reducing the pressure drops in the air filter systems to thereby save valuable energy, avoid unnecessary costs, and reduce CO2 emissions.

For the energy-optimized operation of HVAC systems – while still ensuring that filter efficiency is adequate to deliver the necessary indoor air quality – we recommend Viledon air filters in energy efficiency classes A and B. These filters have a large dust holding capacity combined with a low pressure drop curve, which cause lower energy consumption.

1 Pa = 1 €

1 Pascal less of pressure drop per filter corresponds to savings of 1 Euro per year (8,500 operating hours, volume flow 3,400 m3/h).
