ABSTRACT:
A filtering assembly for an air intake duct for a turbine device for normally removing particulate matter entrained in the air being introduced to the turbine device through the air duct. The improved filtering assembly comprises a filter element for removing particulate matter entrained in air passing therethrough which is mounted in the air duct so that at least a section of the filter element is movable between a filtering position and bypass position. More particularly, the filter element is mounted in the air duct so that when it is in the filtering position, substantially all of the air passing through the air duct passes through the filter element and so that when it is in the bypass position, a substantial amount of the air passing through the air duct bypasses the filter. A suitable sensing device is provided for sensing the pressure differential of the air across the filter element in the air duct and a clamping device is provided which normally clamps the filter element in the filtering position. The clamping device is actuable to release the filter element from the filtering position to allow the filter element to move to the bypass position when the pressure differential sensed by the sensing device is above a predetermined pressure difference. In this manner, air flow will be maintained to the turbine, even if the filter becomes clogged or stopped, thereby preventing a situation in which the turbine might otherwise be starved of sufficient air flow.
