MODELS LEV AND LIV LOUVERED RELIEF/INTAKE VENTS

Model LEV

For exhaust or gravity relief. Capacities up to 103,000 cfm.

Model LIV

For fresh air intake. Design velocity at perimeter of 600 fpm to minimize moisture entrainment. Capacities up to 103,000 cfm.

Aerodynamically designed with generous air flow

areas for efficient performance

Birdscreens are constructed of ½" x ½" galvanized welded wire mesh (Omitted when supplied with optional filters)

Removable hoods are reinforced and braced for extra rigidity and resistance to wind damage. Cross broke for extra strength. Constructed of .050 aluminum

Louvers are precision miter cut and welded for maximum strength. Constructed of .081” extruded aluminum

Louvered on all four sides for full 360º perimeter opening

Multiple tiers for high air flow capacities

Outstanding weather protection*

Vertical snow and storm baffle on base to guard against

storm driven rain and snow

Extruded louvers have double water and snow baffles for

added weather protection

*Louvered ventilators are reasonably weather tight. However, they

are not recommended for use where airborne water droplets from

storms or high winds may damage the interior of the building.

Curb caps are miter cut and continuous welded for maximum strength and water tightness. Constructed of .080" aluminum

OPTIONAL ACCESSORIES

Hinged Hood - for easy access to filters and screens

Insulated Hood - reduces condensation drip rubberized anti-condensation undercoating or 1” fiberglass insulation

Filters - 1” thick permanent aluminum mesh mounted for easy cleaning (add .15” to static pressure listed in the tables when using filters on LIV ventilators)

Insect Screens - 18 ga. mesh aluminum screen attached to the inside perimeter of the louvered opening (add .08” to static pressure for LEV and .03” to static pressure for LIV listed in the tables when using insect screens)

Typical drawings are for dimensional purposes only and are correct within limits suitable for normal installation requirements. They do not necessarily show actual construction.

Aluminum Bird Screens - .050” thick ½” x 1” expanded aluminum located on inside perimeter of louvered openings
