PT Power Tube Fan Make-Up Air System uses a special
CANBERRA Josh Rosen Jersey , July 16 (Xinhua) -- More efforts and money needed to be allocated towards securing the future of Australia's endangered animals, a leading environmentalist said on Thursday.

Speaking to local media ahead of a key environmental summit in Melbourne, the World Wide Fund's Darren Grover called for the Australian government to invest more money into saving 10 endangered species Cheap Cardinals Jerseys , including native birds, the Tasmanian devil and Leadbeater's possum.

The National Threatened Species Summit, being held on Thursday Markus Golden Game Jersey , will discuss an action plan to halt the wildlife crisis in Australia.

Grover said the summit would host a variety of key speakers, including federal Environment Minister Greg Hunt, who is set to announce important first steps in tackling the issue.

"The Threatened Species Summit is an opportunity to explore solutions and discuss practical ways to halt Australia's wildlife crisis at a time when our threatened species are under more pressure than ever before D.J. Humphries Game Jersey ," Grover told Sky News on Thursday.

"Federal Environment Minister Greg Hunt has done a great job of raising awareness about the plight of threatened species but we now need a set of strong actions if we are to prevent further extinctions in Australia."

Hunt released a statement saying he was "pleased" to announce a raft of funding programs at the summit in Melbourne.

"I want to bring these birds back far enough from the brink to survive in the wild long-term. I want future generations to enjoy the color, movement and song they bring to our lives," he said on Thursday.

The news follows a release from Birdlife Australia which showed dramatic decreases in the number of common Robert Nkemdiche Game Jersey , native birds, such as the kookaburra, magpie and the willy wagtail.

Birdlife Australia CEO Paul Sullivan said he was shocked to learn that common native birds were in decline.

"We've known for some time that many rare bird populations are declining but we were not aware of the decline of these very common and iconic Australian birds Budda Baker Game Jersey ," he said on Wednesday.

Grover has called for the Environment Minister to increase targeted funding to ensure the survival of all native birds and animals.

Among the 10 Australian species at "extreme risk of extinction' are the Eastern barred bandicoot, Bellinger River snapping turtle, freshwater sawfish and Swift parrot.

Industrial Pressure Blower Co. makes a PT Power Tube Make-Up Air System a sone of the most economical options for larger industrial plants ventilation air make up.

When exhaust fans are used to provide ventilation Haason Reddick Game Jersey , 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 Chase Edmonds Game Jersey , 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 Mason Cole Game Jersey ,000 CFM.

PT Power Tube Make-Up Air System tube is constructed of thick woven high density polyethylene fiber(8 x 8) 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.
