The invention discloses a ventilation device, which aims to solve the problem that the conventional ventilation device does not have an air adjusting function. The device comprises a pedestal, a high-speed air blower and an annular ejector, wherein the high-speed air blower is arranged at the bottom of the pedestal; the annular ejector is arranged at an air outlet of the high-speed air blower and is fixed on the pedestal; and the air inlet or the air outlet of the high-speed air blower is provided with a vapor generator which is fixed on the pedestal for producing water vapor. In the ventilation device, the water vapor is produced through the vapor generator and is ejected through an atomization nozzle at a high speed to produce fog of smaller granularity, so that a hot air flow can more easily absorb the latent heat of vaporization, and the ventilation device has a humidification effect and a heat absorption and temperature reduction effect on a large amount of hot air sucked by the annular nozzle, and brings comfortable cool air similar to air on the shore of a lake or a sea to the surrounding environment. In the ventilation device, an external circulating device is not required to be mounted, so the cost is low; the space is not required to be closed, so that air convection is guaranteed; and the ventilation device is more energy-saving in the same temperature reduction range compared with a fan and an air conditioner, and can be used conveniently and safely.

This invention provides a small, high efficiency, oil free motor driven compressor/blower suitable for providing pressurized, contamination-free gas and or air to transportation, industrial and aerospace fuel cell systems or other contaminant-intolerant applications. The motor driven compressor/blower rotor assembly is supported by foil air bearings and rotates at high speed by using a high frequency drive. The impeller is a centrifugal type design. The MDC can be easily integrated into the air management system of a fuel cell.

A breath responsive filter blower respirator system for a gas mask including a pressure and control device, such as an optoelectric device and/or a pressure sensor, to control the air flow produced by an air blower. The optoelectric device detects the position of the mask's outflow valve. The pressure sensor measures air pressure in the mask relative to ambient air or the absolute air pressure in the mask. During exhalation, the pressure detector detects an increase in air pressure in the mask and/or the optoelectric device detects the outflow valve in an open position, and then signals the central processing unit to signal the air blower to reduce speed. The reduction in speed reduces air flow in the mask and lowers air pressure in the mask.

An aeration system for a submerged membrane module has a set of aerators connected to an air blower, valves and a controller adapted to alternately provide a higher rate or air flow and a lower rate of air flow in repeated cycles. In an embodiment, the air blower, valves and controller, simultaneously provide the alternating air flow to two or more sets of aerators such that the total air flow is constant, allowing the blower to be operated at a constant speed. In another embodiment, the repeated cycles are of short duration. Transient flow conditions result in the tank water which helps avoid dead spaces and assists in agitating the membranes.
