    Abstract: An air bubble purging system for filters include a venturi valve in the drain line of the filter. The venturi valve is connected to a high pressure source line so that when a high rate of flow is produced in the high pressure source line, a venturi effect is created in the venturi valve to open the venturi valve and produce a vacuum in the drain line so that air bubbles are attracted into the drain line and purged.

    Abstract: A cleanable backflushable re-usable dual full-flow and bypass filter includes a full-flow filter element providing filtered primary flow therethrough, a bypass filter element providing filtered secondary flow therethrough, a bypass tube conducting flow therethrough from said bypass filter element to said full-flow filter element, a venturi creating a low pressure zone aiding secondary flow through the bypass tube to assist in pulling the secondary flow through the more restrictive bypass filter element, wherein fluid, whether main fluid flow in the filtering direction or backflushing cleansing fluid flow in the opposite direction, flowing from the bypass tube changes direction at the venturi. During a backflushing cleaning cycle, a backflush deflector at the outlet end of the bypass tube in the venturi creates the directional change by changing axial flow of cleansing fluid through the bypass tube to radial flow at the outlet end of the bypass tube in the venturi and prevents straight-through rectilinear flow of cleansing fluid from the bypass tube to the filter outlet. Jets are provided, jumping the cleansing fluid across a radial gap between the bypass tube and the venturi throat to a region outside of the venturi and within the hollow interior of the full-flow filter element, to disperse and backflush the full-flow filter element.

    Abstract: An adjustable continuous filtration system for cooking fats and cooling oils. Using a variable orifice restriction such as a valve, the amount of cooking fat or cooking oil recycled to a filter is controlled in accordance with the results of testing the discharged cooking fat or cooking oil for quality control, by changing the size of the orifice. If the discharged fat or oil not within industry standards, the proportion being recycled is increased. If the fat or oil tests appreciably above industry standards, the proportion recycled to the filter is decreased.

    Abstract: A filter system for filtering cleaning solvents includes a first filter unit having mechanical filters such as paper or the like, through which the fluid is first pumped, and a second filter unit having adsorption chemicals, such as clays and charcoal, through which at least a portion of the fluid from the outlet of the first filter unit is passed and the outlet of the second filter unit is in communication with the inlet to the first filter unit for recirculating the fluid therefrom back through the first filter to filter and deposit carbon and clay particles from the second unit on the surface of the first filter unit thereby providing a multi-pass filter system.
