Adaptable dual-directional, differential pressure assembly |
摘要 |
An adaptable dual direction, differential pressure assembly is disclosed. Solenoid valves release controlled bursts of air into a top of a container. A rate of the controlled bursts of air is partially responsive to a pressure differential between atmospheric pressure and that of compressed air in the reservoir. A pleated filter is fitted inside of the container. The pleated filter has an inner wall and an outer wall and has pleatings separated using hot melt glue beads there between. The controlled bursts of air are programmed to be substantially automatically responsive to one or more pressure differentials between an inner wall and an outer wall. In one embodiment, air is drawn from the blower through the pleated filter from the inner wall to the outer wall until a desired pressure differential is achieved. In yet another embodiment, air is drawn through the pleated filter from the outer wall into the inner wall and to draw upwardly out of the top of the container through the blower until a first pressure differential is achieved.
