Bypass Laboratory Fume Hoods

Bypass fume hoods maintain consistent exhaust flow through upper and lower bypass slots to balance face velocity as the sash moves. These units are ideal for labs with sufficient room air supply and offer chemical-resistant interiors and integrated lighting.

Features include:

  • Double bypass design for steady airflow
  • Automatic upper bypass control with sash movement
  • Lower bypass maintains workspace protection
  • Available in resin-chem, PVC, or stainless interiors
  • PVC or stainless sash guides with fluorescent lighting

Add Air Laboratory Fume Hoods

Add air fume hoods integrate a dedicated makeup air plenum to conserve conditioned lab air by reintroducing up to 70 percent of exhaust volume. Bypass airflow and sash control features ensure safe operation.

Features Include:

  • Makeup air plenum conserves HVAC load
  • Bypass design manages airflow balance
  • Interiors available in resin-chem, PVC, or stainless steel
  • Adjustable sash and baffle alignment

Variable Air Volume (VAV) Laboratory Fume Hoods

Variable Air Volume fume hoods adjust exhaust airflow based on sash position to optimize energy use. These systems feature dampers and lintels to provide responsive ventilation while minimizing HVAC demand.

Features Include:

  • Adjustable damper control for airflow efficiency
  • Lintel replaces upper bypass for controlled intake
  • Compatible with VAV control systems
  • Chemical resistant interior and sash options

ADA Compliant Laboratory Fume Hoods

ADA compliant fume hoods provide wheelchair-accessible sash height while maintaining full containment and airflow performance. These models offer chemical resistant interiors and adjustable sash and baffle systems.

Features include:

  • Wheelchair accessible sash design
  • Maintains full airflow performance
  • Resin-chem, PVC, or stainless interiors
  • Adjustable sash and baffle settings
