Balancing filter cost and energy-efficiency

In operating the laboratory, a balance must be achieved between the life-cycle cost benefit of a filter's life and the energy use of the filter's extended life. The longer the filter is in service, the more likely that any increased cost will be recaptured. However, operating the filter to a high final pressure drop requires increased energy use that may nullify the gains in life-cycle payback. The optimum final pressure drop should be analyzed for any particular laboratory installation. [McIlvaine et al., 1992; Lippold et al., 1990; NAFA Guide..., 1993; Kruse, 1991]
