NISCO Fan Co. is a PT Power Tube make-up air system, a sone of the most economical options for larger industrial plants supply make-up.


If the fans are used to provide ventilation, both for industrial and process exhaust and personnel comfort, a vacuum is created in the building. This negative pressure causes several problems:

– Process exhaust systems are less effective and can not properly
– Down flow can occur through gravity vents and then in the back for ventilation. Products stacks and stacks of heaters and appliances combustionfrom
-. Designs emerge that a dsicomfort employees. safe operation of exterior doors may even be endangered.


Our Power solves Tube Fan Make-up Air System all these economic problems, even the coldest day in winter.


> In the winter conventional systems of makeup air have to heat the cold outside air, before it enters the building. It is an expensive process equipment and energy costs. The Power Tube Fan Make-Up Air System is a simpler system that uses heat from the building and basic aerodynamic principles for the care, tempering and distributing make-up air. And that makes it less expensive than the conventional air-Booster buy, install and use.


PT Power uses Tube Fan Make-Up Air System a special propeller fan blades and the fan is mounted, which (is present roof Optional mounting template) has an opening in a side wall of the building near the ceiling . A motorized wall component is open to the outside wall, attached a hood to protect against the elements. A long tube specially reinforced polyethylene is connected to the output of the fan outside air into the building and temperament take by cold outside air with warm air inside near the ceiling of the station before reaching the floor.

Power Make-Up Air Fans are available in sizes 18-48 air flows up the tube up to 40,000 CFM.


PT Power Tube’s Make-up Air System tube of woven thick high density polyethylene (8 x 8) laminated with poly coating with a thickness of 6 mils. It is 3.8 ounces per square yeard material. Bursting strength is 118 pounds per square inch. The material is flame retardant and meet NFPA 701 The tubes are available in two colors: blue and white. One end of the tube is polyethylene factory employed.


enough air make-up should be for the balance and general ventilation process. Usually several Power Tube Fans will be required to distribute the air throughout the facility. If additional tempering of make-up air conditioning in certain areas is necessary, heaters will be added.
