Abstract: A self-cleaning strainer which may be installed upstream of a heat exchanger to prevent debris greater than a critical size from reaching the heat exchanger. The strainer is preferably mounted just upstream of a heat exchanger in order to minimize the possibility of debris reaching the heat exchanger. The strainer comprises a screen element which can be advanced across the flow path of the fluid between two rollers. The screen element is placed so that the fluid must flow across the screen element face to continue through the process pipe; the screen may be perpendicular or parallel to the fluid flow axis of the strainer body or at an intermediate angle to it. Flow blocking members are used so as to direct the flow to pass through the screen element.

Abstract: Electronic equipment having a temperature control air flow passage. A length of filter material has a length portion extending across the upstream end of the flow passage, the filter material being movable longitudinally to replace the clogged length portion with unused filter material. A filter advancement device is operable by a control device actuated when an undesirably low fluid flow rate is achieved through the length portion so as to effect filter replacement. Roller devices give up unused filter material and take up used material. A stepper motor may be used to advance filter material for replacement purposes. The control device is preferably operated upon drop in rotational speed of a fan located immediately downstream of the filter length portion, the speed drop being caused by drag as the filter becomes clogged. Alternatively, the control device comprises a switch which is operated as the filter length portion flexes it becomes clogged, or temperature sensors located at chosen sites.

Abstract: An automatic filter cartridge in accordance with the present invention includes a frame which is formed with an aperture and an elongated filter medium which is attached to a supply roller and a take-up roller. Specifically, the supply and take-up rollers are placed into respective supply and take-up containers which are mounted on the frame across the aperture. The frame is then positioned in the ducting of an air conditioning system to filter the airflow through the filter medium which extends across the aperture. To monitor the airflow through the ducting, the automatic filter cartridge can further include a computer. With this configuration, a sensor is positioned in the ducting to monitor the airflow through the ducting. When the sensor indicates the filter medium in the ducting is dirty, the computer activates a motor to rotate the take-up roller.
