ALTRA AIR Sailfin Fans



Envira-North Systems Ltd.  has launched the latest and most efficient technology available for the large industrial HVLS ceiling fan market.  The Altra-Air Sailfin variable pitch, modulated trailing edge airfoil removes the inefficiencies created by differentiating rotational HVLS fan speeds.  Simply put- a faster tip speed requires less surface area and less angle of attack to produce airflow.  While a slower hub speed requires more surface area and more angle of attack to produce airflow.  The evenly spread deflection creates less disruption in the trailing air stream, producing cleaner air for the following airfoil, less blade flex in the alternating blade assembly and lowers unwanted ( and expensive ) operating load.   All this adds up to greater air speed velocities with less noise created and less money spent operating....not to mention one sleek looking design!.

The Altra Air fan Sailfin fan is used to destratify air in airplane hangers, warehouses, hockey rinks, shopping malls, distribution centers, office buildings, dairy farms or any buildings with high ceilings.  Destratification means drawing the warm air off the ceiling and reusing it at our comfort level which creates a 35% energy savings.  The Altra-Air Sailfin fan can greatly improve the working environment for employees by modulating- "evening out"- the ambient working temperature.  By increasing the speed on this fan, a cooling effect is created during the hot days of Summer which can drop air conditioning cost substantially.

The Eco Power utilizes an electronic commutating (EC) motor installed in the head of the ventilator to enable motorized boost during  perios of low wind speed or special ventilation needs.  The motor can be activated by any digital measure, humidity, gas concentration level, etc.  The standard product is controlled manually by a switch (not included).  Unlike previous attempts to produce a hybrid mechanical / wind vent, ecopower has no motor and fan blade in the throat of the vent.  This is extremely important! Research using AS4740:2000 (performance of natural ventilators) has shown clearly that any obstruction in the throat of a wind driven ventilator will greatly decrease vent performance under wind load.  The level of flow reduction can be 40% or greater.  Also, axial fans located in the throat of wind vents can produce significant noise levels.



Pictured above: Eco Power fans use in conjunction with Stealth model HVLS fans.

Eco Power is one large direct drive centrifical fan.  The bearing system of the motor becomes the bearing system of the ventilator.  This means that the vent can be free spinning under wind load or power activated as conditions require.  The use of an EC motor ensures that the best energy efficiency features available are factored into the product design.

How Can Ventilation Be Free?

Are you aware of the hidden costs of exhaust fans?  The immediate reaction by facility owners to improve ventilation is to add some exhaust fans.  Exhaust fans will move air to be sure, but when you stop to think about the cost of exhaust fans is it really an effective approach?  First you have the fan equipment cost, then you have the structural modification costs to handle the heavy weight of the fan, then you have the motor starter costs, electrical operating costs and finally you have frequent maintenance costs.

What if we told you that you could ventilate your plant for free?

It's true! Most buildings are creating a natural gravity effect where the hot air is rising from the floor to the roof creating a positive pressure at the upper levels and negative pressure at the lower levels.  Gravity or stack effect is caused by convection (hot air rises), the temperature difference from inside the building as compared to outside the building and the height of the building.  If the correct gravity opening is installed at the roof, the positive pressure caused by the stack effect will enable the heat to leave the building.  As the heat leaves the building through the roof opening, the air at the floor will be displaced by the cooler air entering the building from lower levels.



Why pay for ventilation when Mother Nature will do the work for you?

A properly designed gravity opening will provide ventilation due to stack effect, but by harnessing the wind, ventilation can be improved by 600% or more!  Antiquated "doghouse" style gravity openings are susceptible to wind direction and can actuallycause downdraft shutting off exhaust ventilation.  With the Hurrican wind driven turbine ventilator, the wind strikes the verical vanes causing the head to rotate.  The rotating action generates a powerful area of low pressure causing additional air to be exhausted from the building.
