Ventilation Systems

VAL-CO V-Fan
VAL-CO V-Fan
VAL-CO "V" Fan

  Information Sheet for 54"

The VAL-CO V-Fan™ is a variable speed, direct drive fan. The V-Fan provides higher total CFM at full speed as well as remarkably high CFM/Watt measurements at low speeds. During minimum ventilation, it’s more efficient to use a 54” V-Fan running at low speed than a standard 36” fan running at full speed. A 54” V-Fan at 50% speed can move 13,400 CFM at .05” SP while achieving 53.8 CFM/Watt. That is more than a 300% increase in efficiency!


VAL-CO HyperMAX Fiberglass Fan

  Information Sheet for 54"

VAL-CO HyperMAX Fiberglass Fans - 36", 50", 54"
VAL-CO HyperMAX Fiberglass Fans - 36", 50", 54"

 

Val-Co HyperMAX fiberglass fans are constructed with a corrosion-resistant, molded fiberglass housing.  Using new technology in computer-aided design, the oriface, blade, cone and motor combinations optimize the use of the motor's power curve.  An auto belt tensioner reduces maintenance.  The motors have sealed ball bearing and thermal overload protection.  With higher cubic feet per minute (CFM) and CFM/Watt per fan, producers need fewer fans per house to achieve the desired air moving capacity.  Exhaust cones are available in fiberglass or poly.

DirectAire Stir Fan - 2 speed, 20"
DirectAire Stir Fans


  Information sheet - 20" Stir Fan

DirectAire Stir Fans are important in your effort to reduce costs and improve the environment inside your buildings during summer and winter months.  Because warm air rises and cool air falls, there is often a 5 to 8 degree Fahrenheit  difference between the ceiling and floor temperatures.  One way to help minimize this temperature difference is to install DirectAire Stir Fans.  The main purpose of air circulation is to cool and control the climate to reduce heat stress on your animals and keep production at the maximum level.  DirectAire Circulating Fans keep your building dry by reducing the collection of moisture and condensation, and also to help dispel gasses and odors.   The recycling of heat will reduce fuel costs and create a healthy environment for animals and workers.

Inlets

Double L - AC3010 Ceiling Inlet

  Information Sheet

Double L - AC3010 Ceiling Inlet
Double L - AC3010 Ceiling Inlet
The 360 degree insulated actuated ceiling inlet was designed for cold climate conditions.  The AC3010 Actuated Inlet has no blades to break, fall out, or get stuck open or closed. Air enters AC3010 machine actuated inlet from attic and is evenly distributed in all 360 directions into the poultry barn. The air travels along the ceiling instead of falling directly onto the birds. The AC3010 Actuated Inlet gently mixes air without creating a draft resulting in even temperatures throughout entire room.
  • No freeze-up and minimal moisture buildup
  • Four Point Pivot heavy-duty, durable, Reactive Injection Molding (RIM) construction and heavy-duty PVC and stainless steel components allow for easy operation and minimal maintenance of vent
  • Tightest seal on market - no air leakage when attic air vent is closed
  • Drier litter conditions and less humidity
  • Larger bottom board (removable lid) than competition - directs air along ceiling with no downdraft on animals

 

Double L - GC1140 360° Insulated Gravity Inlet

Double L - GC1140 - 360 Degree Insulated Gravity Inlet
Double L - GC1140 - 360 Degree Insulated Gravity Inlet

  Information Sheet

The GC1140 Fully Insulated Attic Air Inlet is a patented 360 degree airflow poultry gravity ceiling inlet. The GC1140 Attic Inlet's 360 degree radius corner design increases fuel savings, air distribution, and air mixing. Drier litter conditions and less humidity are also benefits of the GC1140. From ease of installation to its excellent performance, the GC1140 Fully Insulated Gravity Inlet has proven to be an exceptional poultry inlet for poultry grower ventilation.


Air enters the inlet from the attic and when the inlet is open, air is evenly distributed in all directions into the poultry house. The larger bottom lid directs airflow from the attic inlet along the ceiling instead of falling directly on the chickens or turkeys. The GC1140 Gravity Inlet gently mixes warm and fresh air without creating a down draft, resulting in more uniform house temperatures throughout the animal room. Thus, growers are able to maintain higher ventilation rates during cold weather without sacrificing house temperatures or wasting fuel.
