  • Publication number: 20120000356
    Abstract: A powered air cleaning system has a flow path extending through the system from an inlet to an outlet. A motor-driven fan is located along the flow path to draw particulate debris laden air into the inlet and rotate it about an axis to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port ejects particulate debris laden air from the stratified rotating flow in the system. At least one de-swirl component located within the rotating flow aerodynamically redirects clean air from the innermost orbits of the stratified rotating flow toward the outlet to provide a positive airflow pressure out of the outlet. The system has a variable speed fan motor and an integrated controller for adjusting the speed of the motor and thereby the flow rate of clean air through the outlet of the system. The controller receives a signal that is a function of airflow requirements of a device supplied with clean air by the system.

  • Patent number: 7056368
    Abstract: A powered air cleaning system (1) and air cleaning method are disclosed. The system has a flow path (22) extending through the system from an air inlet (4) to a clean air outlet (5). A motor-driven fan (24) located along the flow path draws particulate debris laden air into the inlet and rotates it about an axis (A—A) to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port (25) is provided for ejecting particulate debris laden air from the stratified rotating flow in the system to the environment. An air filter (9) located within the rotating flow and across the flow path upstream of the outlet filters air from the innermost orbits of the stratified rotating flow.

  • Patent number: 6953491
    Abstract: A portable, light-weight exhaust fan that can be easily and quickly carried to and set up in a localized area to safely, efficiently and substantially remove airborne materials thereby overcoming the above and other drawbacks of conventional exhaust fans. Exhaust fans in accordance with aspects of the present invention may be used to ventilate a localized area such as an enclosed room and may be placed in any aperture such as a window or doorway to remove substantially all airborne material from the air passing therethrough, and to exhaust filtered air directly or indirectly to the surrounding environment. An exhaust fan constructed such that air traveling along an exhaust path through the fan is prevented from contacting components of the fan that can be damaged by exposure to the airborne materials. This enables the exhaust fan to efficiently remove airborne materials from a localized area while preventing the same materials from adversely affecting the operation of the fan.

  • Patent number: 6719830
    Abstract: Disclosed is an improved vacuum cleaning apparatus utilizing a self-sustained vortex flow in a centrifugal separator. More specifically, vortex flow is maintained via pressure differentials allowing the ejection of dust and other particles without bags, filters, or liquid baths. Furthermore, the impeller inside of the separator serves the dual purpose of moving air through the system as well as creating a cylindrical vortex fluid flow providing an efficient and simple configuration. Also disclosed herein is a complete toroidal vortex vacuum cleaner in which a toroidal vortex nozzle is used in conjunction with the centrifugal separator. The vacuum cleaner exhibits recirculating airflow that not only prevents unseparated dust from escaping into the atmosphere, but also conserves the kinetic energy of the flowing air. The present invention excels in producing clean air of a better quality more efficiently, more quietly, and more simply than the prior art.

  • Publication number: 20040025482
    Abstract: In a centrifugal separator, the rotor (19) of which is adapted to be driven by means of a gaseous driving fluid, the rotor itself supports a ring of turbine blades (34) extending around the rotational axis (R) of the rotor. A stationary nozzle (40) is adapted to direct a flow of the driving fluid towards the ring of turbine members (34). After the driving fluid has passed between the turbine blades (34) and has influenced them for driving of the centrifugal rotor, it enters a reversing chamber (41) formed by a stationary reversing member (42). In the reversing chamber the driving fluid is caused to change its direction and is then conducted again towards the ring of turbine members (34) in order to be utilized a second time for driving of the centrifugal rotor.

  • Patent number: 6648935
    Abstract: A two stage extracting blower that cleans liquid and solid contaminants from supply air, and provides high velocity air for cooling equipment, personnel and/or structures. In a first air cleaning stage, the blower uses air velocity and the centrifugal force of a rotating impeller to separate heavier contaminants entrained in a dirty air stream into a rear partitioned chamber of the blower housing. In a second air cleaning stage, the blower uses centrifugal forces imparted by the impeller on lighter contaminants to cause the contaminants to be collected in a skimmer provided in the partially cleansed air stream prior to release of the air stream from the blower.

  • Patent number: 6562109
    Abstract: Trap apparatus and method for removing contaminants from the gaseous effluent flows from chemical vapor deposition chambers and processes by flowing the particle laden gas into an upper chamber of the trap apparatus, imparting additional kinetic energy to the powder particles to enhance separation of the powder particles from the gas, and then flowing the gas, sans the powder particles, out of the trap, while the powder particles fall into and are captured by a lower chamber positioned below the upper chamber and remote from the flowing gas. An impeller positioned in the upper chamber in the inlet path imparts the additional kinetic energy. For some reaction gas systems, an optional reactor with hydrophillic, rotating growth substrates enhance and accelerate growth of solid particles, which are then dislodged from the media, and fed by the flowing gas into the upper chamber for capture as previously described.

The thus rotating air passes through an annulus to a rear portion of the housing in which the air flow is caused to back up. As a consequence, some solid debris in the forward housing portion moves into a forward isolation region from which that debris is ejected through a forward exit orifice. Other solid debris in the rear housing portion enters a rear isolation region from which it is ejected through a rear exit orifice. The thus-cleaned air passes through an exit gap to an air outlet from which it exits the air cleaner for use.
