The Importance of Energy Efficient Filters

Energy consumption is one of the main cost items related to air filtration. There is evidence that an average of seventy percent of the total cost of filtration can be attributed to energy consumption. It is therefore important that one purchase air filters which offer energy savings. This enables one to save money while also reducing the burden on the environment. The purchase of inferior quality filters can ultimately entail both higher energy costs and increased replacement frequency.

Together with customers, AFPRO has succeeded in reducing the energy consumption involved in air filtration, often with notable results. Simple modifications of the filter configuration have proven to yield considerable energy savings, while continuing to provide the required air quality.

AFPRO Filters views the manufacture of air filters with a low resistance as a spearhead. The lower the resistance, after all, the lower the energy costs. Research has shown that if the resistance of a filter is reduced by an average of 1 Pa, the costs of air filtration also decline by around 1 euro per annum. This becomes clear from the model calculation below. The air treatment cabinet in the following example requires ten bag filters to achieve the envisaged air quality.

It has been assumed that the fans are to run non-stop during the operating time of one year. The remaining data can be derived from the table above. These show that, in the event of fluctuating energy prices, the lower resistance yields savings on energy costs of over 600 euros. Even when the slightly higher purchase price of the filters is deducted from this sum, considerable savings are still made.

The message is therefore clear: When purchasing an air filter, one should consider not only the purchase price, but also the energy costs. AFPRO Filters would be pleased to advise you on such matters. Our sales staff and technicians collaborate in analysing the possibilities of cutting costs while maintaining air quality standards, by modifying the filter configuration.
