Ventilation By Fan Tube Make-up Air System
By: oleg tchechel
Air Make-Up fan system is a new ventilation concept. It utilizes some aerodynamic principles for supplying, tempering and distributing make-up air in a building in cold weather. It offers more efficiency, economy and comfort than most conventional make-up air units.(read

Power Tube Ventilator
By: oleg tchechel
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.(read

Roof Ventilators For Reversible Air Flow
By: oleg tchechel
Roof Recirculators function as regular power roof ventilators in warmer weather and as an energy-saving recirculation air system in cold weather. Each unit is equipped with a reversible fan that distributes warm ceiling air thoughout the plant and reduces the builing's heating requirements. With a flip of a switch it can function as a conventional roof ventilator. There are two unit types: 1) for exhaust and recirculation; 2) for exhaust, supply and recirculation.(read

Blowers Connected In Series
By: oleg tchechel
Series and parallel connected blower installations are often used to meet performance ranges beyond normal single stage blower capacities. For systems that require high ststic pressure, and especially high pressure TOGETHER with high temperature (where standard multi stage, positive displacement, screw, or regenerative type blowers can not be used) series of single stage centrifugal blowers can be used. Many times additional blower in the system can be advantageous. For instance, where two blowers are operating in series and one breaks down, the other may be able to "limp" the system along while the necessary maintenance is performed. Having on blower continue in operation can often allow limited production while the other is being repaired. Also, there are cases where having one blower continue in operation could prevent or at least minimize system or equipment damage from such things as high temperature ot contaminated airstreams.(read

Super Quiet Packaged Vaneaxial Fan
By: oleg tchechel
Vaneaxial Series VA fan is an ideal booster fan for prolonged ducts. Unlike inline centrifugal ventilator, that also generates rather high pressure, the air comes out not from a peripheral outlet ring area, but distributes evenly across its outlet opening like in true axial blowers.(read

Recommendation For Building Ventilation And Cooling
By: oleg tchechel
The first step toward controlling the hot air porblem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in the cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery, it should be exhausted from the building near its source.(read

Frp Axial Fan Ventilators
By: oleg tchechel
AB Blower fans are the finest quality blowers available for efficient movement of corrosive, humid, or polluted air, gases, and fumes. These fire-retardant and corrosion-resistant plastic fans are specially designed and especially suited for hostile applications where coated metal blowers typically corrode. Northern Industrial fans are proven thoughout the world and clearly recognized for superior quality, reliability, and efficiency.(read

Axial Versus Centrifugal Fan
By: oleg tchechel
Variable pitch blade in axial fan blower is used where precise control of static pressure within supply ducts is required. The fan wheel will spin at a constant RPM . The blades follow the control pitch hub. As the hub moves toward the rotor the blades increase their angle of attack and an increase in flow results.(read

Industrial Ventilation Blowers And Fans
By: oleg tchechel
Fan ventilators are classified into propeller, tube axial and vane axial styles, and each type has different characteristics. Propeller fans consist of only a motor and propeller and therefore are the simplest. Tube axial are similar to propellers but has a venturi around the propeller to reduce the vortices. Vane axial fans are equipped with vanes that trail behind the propeller in the airflow to straighten the swirling flow.(read
