Components for Commercial HVAC
The US commercial HVAC segment exceeds $40-50 billion. Brush seals and EPDM gaskets are consumed at extraordinarily high volumes - every damper, VAV box, and air handling unit requires blade-edge seals and perimeter gaskets. Millions of dampers are manufactured annually, each needing precision sealing components to meet AMCA leakage standards.
HVAC damper manufacturers like Greenheck Group produce millions of damper and VAV units annually, each requiring brush or EPDM blade seals. Fire dampers must meet UL 555 certification, smoke dampers UL 555S, and volume control dampers AMCA 500-D. ASHRAE 90.1 energy standards continue to tighten, driving demand for lower-leakage sealing solutions.
Applications
How Our Components Are Used
Damper Blade Seals
Brush or EPDM seals on damper blade edges that minimize air leakage when dampers are closed. Critical for energy efficiency and fire/smoke containment.
VAV Box Gaskets
Perimeter gaskets and seals for Variable Air Volume terminal units, ensuring rated airflow performance and leakage class compliance.
Air Handling Unit Seals
Access door gaskets, panel gaskets, and perimeter seals for AHUs, rooftop units, and fan coil units.
Fire & Smoke Damper Seals
UL-rated seals for fire dampers (UL 555) and smoke dampers (UL 555S) that maintain integrity during fire events.
