AB Blower Co. makes low Profile Positive Pressure Ventilators that have been designed to fit in tight compartments ans small spaces without scarificing performance or features. These compact ventilation blowers are available is both gasoline driven conviguration and with 115230V single phase electric motor. The Positive Pressure Blower is a high volume fan use to pressurize a burning structure Adidas Filip Forsberg Jersey , in case of fire, in order to force the smoke out. Positive Pressure Blowers are portable, gasoline powered fans, most of which utilize a 5.5 horsepower engine. The theory of positive pressure ventilation is based on the principal of even pressure distribution. Once a structure is pressurized, air and smoke can be forced out through any opening (similar to escaping from an inflated baloon). Electric smoke ejectors (negative pressure ventilation) can be used for smoke removal but this has proven to be inferior to positive pressure ventilation. What makes Positive Pressure Ventilation superior to negative pressure ? * The risk of injury from the engaged structure is reduced while placing the fan in operation. * Positive pressure ventilation is faster to set up and requires fewer personnel. * The Positive Pressure Blower has a self contained power source, while electric fans require cords and adaptors. * Smoke and heat is removed from all levels of the structure unlike negative pressure which can result in localized extraction. * Quicker results. After initial knockdown, positive pressure ventilation can be initiated and will show immediate improvements in the interior conditions. * It allows replacement of contaminants with vital cooler, cleaner air - especially in sealed or windowless buildings. It's also very effective in large and compartmentalized buildings, warehouses, schools, etc. * Quick results allow firefighters faster entry due to lower heat levels and improved visibility. The following criteria should be considered for effective use of Positive Ventilation: - The cone of air must cover the intake opening. The fan must be placed the correct distance from the structure such as that the cone of air forms a seal around the opening. - The size and location of the discharge is important. The discharge, if at all possible should be as high and far away from the intake as is practical. The discharge size should be between 34 to 12 times the intake. This may not always be possible as the fire may have already dictated discharge locations and sizes; but whenever there is a choice, the above criteria should be used. - It is important to control the ait flow between the intake and discharge. Positive pressure ventilation can move air long distances if proper control is maintained by opening and closing doors, windows, etc. It is important that firefighters understand not to open the structure too much: ie breaking windows, etc. The standard features of AB Blower Co. Positive Pressure Ventilators include: fold down "T" handle; 8" pneumatic tires with full width axle; a "tilt and lock" device that allows the unit to be angled 20 degrees up or down with infinite positions in between; sturdy and light 1 inch wrap around frame. Explosion proof electric motors are available as drivers too. The optimum ventilator placement distance on most 6'6" doors is about five to six feet away. If placement is too close, the seal won't be achieved. If placement is too far away, the cone of air will be hitting well outside the opening.

BSEC 2008, which will be held in India in November, is a 3 day international exhibition, co-located with six other major defence & national security events including the 2-day BSEC Conference and the Defence and National Security (DNS) Leadership Summit. The event will bring together a large number of end users and buyers from Indian and international border, internal & industrial security forces; coast guards; federal & state police forces; airports, immigration & disaster management authorities; governments and other key homeland security associations. The event is being launched after several months of research conducted by Informa in India, the US, Europe, Asia and other key regions. According to General V.P. Malik, former Chief of the Army Staff 芒鈧揼eo-politically and strategically, India enjoys a unique centrality in the security zone of South Asia. Its 3.1 million square kilometers territory has land borders with six countries, covering approximately 15,500 kilometers. It has special ties with each of her neighbours: of ethnicity, language, culture, common historical experience, or of shared access to and dependence upon vital natural resources. Although there are no serious boundary problems with neighbours other than China and Pakistan, there are many border issues like trans-border secessionists芒鈧劉 sanctuaries, terrorism, immigration, gun-running and narcotics, which affect regional security.芒鈧? BSEC 2008 will allow leading solution providers to showcase key technologies and methodologies that would be relevant to an audience of senior decision-makers from Indian and international buyer and end user communities. General Malik adds that 芒鈧.
