Adhesive Applications in HVAC Systems
Adhesive solutions are used in various production phases of HVAC systems, particularly in HVAC filters and components of the air filtration system.
Frame Assembly and Perimeter Sealing
A frame made of particleboard or metal is built around the filter medium to provide structure to the filter.
Metal-Media Bonding
A metal grid is applied to the filter medium to provide structure, creating a corrugated configuration of the media.
Pleating
The adhesive is applied to the filter medium before pleating, which occurs immediately after to set the shape.
Pleat Stabilization
The adhesive is applied along the top of an already formed pleat to maintain its geometry.
Side Seam Sealing
The seams, typical of bag filters, are sealed to ensure filter effectiveness.
Metal Frame Attachment
In some industrial HVAC filters, the metal frame is bonded directly to the filter medium.
