The WB-MAX Walk-in Fume Hood is designed for laboratories that require a large compartment to handle their fume control needs. This unit provides multiple standard and optional features for air control, including optional Add Air (Make-up Air) System. This Fume Hood is ideal for most laboratory exhaust application needs. The narrow design of the hood allows easier installation by enabling it to fit through the width of a standard doorway opening. This unit includes an internal bypass opening, located above the sash, which allows for a constant exhaust volume while maintaining a consistent face velocity. The bypass adjusts automatically when sash is raised or lowered. Additional Features Include:
Continuous air flow across the work surface with lower airfoil bypass, even with sash fully closed.
45 degree front fascia to eliminate air turbulence.
No Exposed Steel Fasteners on Interior or Exterior of Hood
Double side wall construction allows for installation of many service outlets / fixtures.
Easily removable interior and exterior side access panel(s)
