Common use of INLET FILTER COMPARTMENT Clause in Contracts

INLET FILTER COMPARTMENT. The inlet filter compartment sits on a steel support structure upstream of the gas turbine. The elevated arrangement provides a compact system and minimizes pickup of dust concentration near the ground. The two stage inlet filter is comprised of a prefilter and a high-efficiency filter. The media-type prefilters provide an inexpensive, disposable stage of filtration. The prefilters usually extend the life of high-efficiency filters by a factor of about three. The high-efficiency filters use filter medium appropriate for the site environmental conditions to achieve good collection efficiency for all particles, including those as small as 1 micron. Because the collection efficiency is very high, the air quality downstream is also high, even when the ambient air is badly contaminated. The filter elements are contained within a fabricated steel enclosure which has been specially designed for proper air flow management and weather protection. As the outside of the filter elements become laden with dust, increasing differential pressure is sensed by a pressure switch in the plenum.
