 Our LA-series hood offers added flexibility over our modular BV-series by allowing for custom dimensions and design features such as side viewing windows and pass-through ports. The full bias of the side posts enhances air smoothness at the sash perimeter with minimal reduction in working width (1/2”) over the BV. In the Iroquois tradition of performance, durability and value, the LA comes with a long list of standard equipment.
Standard features include:
- Two hood heights in stock – 48” with 42” interior height; 58” with 48” interior height
- Welded superstructure for structural rigidity and design flexibility to accommodate custom hood sizes and features
- Three-piece baffle system with adjustable upper and lower dampers to regulate lighter- and heavier-than-air gases
- Airfoil around full perimeter of sash opening, with electrical fixtures and plumbing controls mounted on bias surface
- Side post electrical and plumbing knockouts in standard or ADA configuration
- Bypass grill with adjustable louvers to control bypass air volume
- Full frame, stainless steel vertical sash with integral stainless steel finger pull
- Stainless steel sash guides, lower airfoil, duct collar
- Sash/counterweight pulley system utilizing four 2-1/2"-diameter pulleys for unexcelled smoothness and durability; full-width counterweight featuring “Tilt-Lock” for additional safety
- Fluorescent light fixture – 2’ or 4’ (bulbs not included) with vapor-proof light glass sealed to top panel
Optional equipment include:
- Liner material – choice of nine non-asbestos materials
- Auxiliary air bonnet – installs at front panel location to supply 70% of hood air from outside building. Requires its own blower and duct; moderate tempering of auxiliary air is recommended.
- Electrical switches and receptacles – pre-wired using U.L. listed components and meeting N.E.C. and the most stringent local codes
- Fluorescent or vapor-proof incandescent light fixtures; explosion-proof incandescent light fixtures for hazardous (classified) locations
- Service fixtures – remote control water and gas fixtures with chrome or epoxy-coated (color-coded) outlets by WaterSaver™ pre-piped to meet the most stringent local codes. Use of hard copper tubing with soldered unions assures joint integrity from factory to service hookup.
- Choice of sashes – vertical rising (standard); top-hung horizontal sliding; combination (vertical /horizontal); interlocking vertical (disappearing post)
- Sash stop
- Ceiling enclosure
- Air velocity monitor/alarm
- Automatic sash closer
- Countertops – cast epoxy or stainless steel, dished, with service slots and sink cutout as specified
