Bellmouth Spigot with Balancing Damper
1. The bellmouth spigot with balancing damper is light weight but strong and stackable,which is very convenient for storage and transport. Made by galvanized steel.
2. Uniquely designed with "Duct Lances " to help secure flexible duct and use in air conditioners (AC), dryers, exhaust, extractor or range hoods, heating ducts, vents and other HVAC applications. Also the surface has been treated very smooth.
3. The damper flap opens and closes manually at low air volumes. The position of the chute is controlled by the spigot, and the opening of the blade can be adjusted by sliding the bolt on the chute over it, thus controlling the air volume.
4.As a general purpose take off/ outlet for use with air-conditioning and extraction systems, the spigot is pressed from prime galvanized steel and formed with a radius "bell-mouth" design to allow highly efficient entry of air to the spigot from the main supply duct with minimal turbulence, noise and pressure loss.
5. It has multiple specifications to meet the requirements of different pipe diameters. The specific sizes are shown in the table
