In the exemplary embodiment shown, the blower is, in combination, a motor-driven centrifugal blower rotatable about a blower axis to create the airflow, and a scroll surrounding the blower wheel and adapted to direct the airflow from the blower wheel forwardly from the housing. In this exemplary embodiment, the deflector is movable about a pivot axis perpendicular to the blower axis between a heating position wherein the airflow is steered through the heating element and a cooling position where the airflow is steered not through the heating element.

A filter housing includes an inlet for receiving airflow, a cavity for receiving a filter and an airflow passage between the inlet and the filter. At least one vane is positioned in the airflow passage for partitioning the airflow passage into a plurality of ducts. Each vane has a non-linear shape in the direction of flow through the airflow passage. This helps to reduce acoustic emissions from the machine since sound waves emitted by the fan and/or motor are caused to bounce off the vanes, which allows the vanes to absorb some of the sound energy. The filter housing can form part of a vacuum cleaner.

An airflow rate regulating device which is installed in a vacuum unit that collects contaminants from a processing station in a controlled space. This device enables a vacuum unit to maintain a continuous suction of contaminant particles from a processing station when there are pressure variations in the controlled space. The airflow rate regulating device is mounted in a suitable cabinet 88 and connected to a vacuum source. The airflow rate regulating device has a casing divided into two chambers separated by a wall having an passageway through which air flows from one chamber to the next. Each chamber features an airflow rate regulation valve comprising a movable member extending across the flow of air passing through the casing, that can be adjusted using counterweights. When a pressure disturbance occurs in the controlled room from a door opening, or when a hose leading the contaminant source is disconnected, the airflow rate regulation valves react to maintain sufficient vacuum pressure at the contaminants source. Since the airflow rate regulating device is mechanical, its response time to pressure is nearly instantaneous.

Disclosed is an electrostatic aerosol concentrator for the concentration of aerosol particles and their collection for subsequent analysis. The concentrator comprises an airflow chamber that includes alternately energized and grounded electrode elements that work in concert to impart radial inward motion to charged aerosol particles and focusing them toward an enriched aerosol outlet. If desired, filtered air inlets may be used to provide a sheath of aerosol-free air along the chamber periphery and prevent deposition of particles onto electrode surfaces. Aerosol particles entering the airflow chamber may carry a positive or negative charge naturally, or a charge may be induced on the particles using a charging section located upstream of the aerosol inlet. Natural or induced charges on the aerosol particles may be used to selectively concentrate subpopulations of aerosol particles from a mixture of particles. For example, bacterial spores or aerosolized viruses may be selectively enriched without concentrating other aerosol particles. The particles of interest are focused and collected at an aerosol rich outlet in a small air volume, while the majority of the airflow, stripped of particles of interest, is purged to the atmosphere through an aerosol lean outlet.

A ventilation unit is for ventilating an indoor space, and incorporates an air cleaning device and mechanical restrictor for controlling a restriction to a flow resulting from a pressure differential across the unit. There is determination of the inside and outside air pressures in the vicinity of the unit and of air quality parameters inside and outside. The air cleaning device and the mechanical restrictor are controlled in dependence on the determined air pressures and air quality parameters. This provides a fan-less, and hence low-power ventilation unit, which relies on throttling the natural air flow across the unit to provide flow control, and hence enable control of air quality. The air cleaning device may be operated only when the flow is into the inside space, saving power.
