In addition to the systems designed to operate with high pressure centrifugal and axial airmovers, specially designed unit exist that create even higher-pressure airflow. These units are specifically designed to force air into or out wall cavities or other interstitial spaces, or under flooring materials for efficient drying of otherwise inaccessible areas. This structural drying equipment is designed primarily for drying wet wall, ceiling, and other assemblies including complex flooring systems. These systems can be classified according to pressure ranges and by manner in which they handle airflow through ducting and attachments.
These systems have higher pressure capabilities and is necessary to overcome the resistance of small diameter air delivery systems, attachments, and the restriction of tight airspace’s where moisture can be trapped.
Attachments can be affixed to these systems for filtering, directing, and manipulating air.
Such manipulation could include utilising ducting and wall cents to direct air beneath floor systems with sleeper or flutes, and into wall or ceiling cavities.
