Tenderall Fan Co. engineers PT Power Tube Make-Up Air Systems a sone of the most economical options for larger industrial plants ventilation air make up.

When exhaust fans are used to provide ventilation Cheap New York Giants Hoodie , both for industrial and process exhaust and personnel comfort, a negative air pressure is created within the building. This negative pressure causes several problems:

- Process exhaust systems are less efficient and may not work properly.
- Down flow can occur through gravity vents and result in the back venting of products of combustionfrom flues and stacks of heaters and process equipment.
- Drafts are created that are a dsicomfort to employees. Safe operating of outside doors may even be impaired.

Our Power Tube Fan Make-Up Air System solves all of these problems economically, even on the coldest winter day.

In the winter, conventional make-up air systems have to heat the cold outside air prior to introduction into the building. This is an expensive process in both equipment and continuing energy cost. The Power Tube Fan Make-Up Air System is a simplier system that utilizes wasted building heat and basic aerodynamic principles for supplying, tempering and distributing make-up air. And that makes it less expensive than conventional make-up air systems to purchase, to install and to operate.

PT Power Tube Fan Make-Up Air System uses a special propeller fan with straightening vanes and fan housing mounted to an opening in a building sidewall near the ceiling (an optional roof mounting model is available). A motor operated wall shutter is attached to the outside wall opening under a protective weather hood. A long specially constructed reinforced polyethylene tube is connected to the fan discharge orifice to carry fresh outside air throughout the building and temper it by mixing cold outside air with warm inside air near the plant ceiling before it reaches floor level.

Specially sized and spaced discharge holes in the polyethylene tube produce relatively high velocity turbulent jets of air. This turbulent jet flow swirls and mixes surrounding air particles resulting in the entrinment of the warm ceiling air and the complete tempering of very cold outside air within a relatively short distance. The result is heated make-up air at the price of unheated make-up air.

Power Tube Make-Up Air Fans are available in Sizes 18 to 48 for for air flows up to 40,000 CFM.

PT Power Tube Make-Up Air System tube is constructed of thick woven high density polyethylene fiber(8 x laminated with poly coating to a thickness of 6 Mils. It is 3.8 oz. per square yeard material. Burst strength is 118 Lbs per square inch. The material is flame retardant and complied with NFPA Standard 701. Tubes are available in two colors: blue and white. One end of the polyethylen tube is factory dealed.

Sufficient make-up air should be provided to balance exhaust from general ventilation and process ventilation. Usually several Power Tube Fans will be required, located to distribute air throughout the plant. If additional tempering of make-up air in specific plant areas becomes necessary, unit heaters can be added.

Dental health is in large part genetic, but good dental care can make taking care of your children's teeth much easier. Understanding how some common problems work is very important to developing and implementing a dental health plan for your children that will last into their adult lives.

Many people think eating the wrong foods or drinking sugary drinks are the worst things for your teeth, but many of those thoughts are not accurate. There are some things that are better for the health of your children's teeth. These include fruits and vegetables that are rich in fiber, many dairy products, and varieties of green and black teas.

The myth is that candy is one of the worst things - true, candies that stay in your mouth for a long period of time are not good for your teeth, but neither are simple carbohydrates like pasta and bread, and fruit juice and citrus fruits can cause problems of their own if you hold them in the mouth for too long.

But understanding how plaque forms is essential in knowing how to keep your children's teeth healthy long into their adulthood, and establishing the proper habits are very important. Children are very smart, and can understand why establishing these habits is so important, especially if you explain to them why brushing and flossing are so important.

Some foods can increase the rate at which plaque can form on your teeth, but the growth of plaque is a natural phenomenon that will occur even without the eating of food. Failure to remove plaque by brushing and flossing will result in the formation of tartar, and this is what causes the most serious dental problems, caries (cavities), gingivitis and periodontitis. Plaque, if left undisturbed on the teeth, will begin to turn to tartar within 24 - 48 hours.

Once tartar forms it is very important to have it removed by a professional tooth cleaning. Left unchecked, tartar growth can result in serious long term degradation of the bone structure which supports your teeth (this is known as Periodontitis).

Fortunately, brushing and flossing at least twice a day interrupts the growth of plaque. Plaque is a result of the mouth's natural process and is formed by the presence of bacteria and your body's own processes.

Understanding that plaque will form in the mouth whether or not you eat is very important in maintaini.
