A horizontal cowl is a “male” type of ventilation accessory used in ductwork systems to cover the end of a duct and facilitate the discharge of air horizontally. Unlike standard cowls, which direct air downward, horizontal cowls allow air to be expelled parallel to the ground.

Description:

Material: Manufactured from galvanized steel

Design: The horizontal cowl features an outlet that directs air horizontally, comeplete with mesh to elimate ingress of debris or pests. Open at 45° to facilitate discharge of air and reduce the possible intake of rain water.

Uses:

• Horizontal Air Discharge: The primary function of horizontal cowls is to expel air horizontally, away from the building or structure

• Reduced Ground-Level Contamination: By directing air parallel to the ground, horizontal cowls help minimize the concentration of pollutants to nearby building or footpaths

• Preventing Recirculation: Similar to jet cowls, horizontal cowls help prevent the recirculation of exhaust air back into the system or nearby air intakes by directing air away from the building.

Installation:

• Mounting: Horizontal cowls are typically mounted on the end of exhaust ducts using self drilling tek screws or rivets

• Sealing: Proper sealing is essential to prevent air leaks and maintain system efficiency

• Support: Adequate support and bracing may be required to ensure the cowl remains securely in place, especially in areas prone to high winds.
  

In summary, horizontal cowls are essential components in ductwork systems, providing an effective means of expelling air away from buildings and structures while minimizing ground-level contamination and promoting environmental compliance and safety.
