TUNNEL VENTILATION
(Wall-Mount Exhaust Fan)

Ranked Higher in Efficiency by U. of Illinois!

CONE FAN

Higher, Quieter Air Flow
Aerodynamically Engineered!

A 33% heavier-gauge housing than competitors' clone models

B Oversized intake opening — Increases air flow capacity

C Aluminum shutters — micro balanced to reduce air drag

D Exclusive EZ-swivel shutter fasteners — for quick, tight mounting

E Housing extends straight-out, thru wall, for tighter wall seal

F Housing slopes down, beyond wall, for less air resistance, and to protect components from weather, plus aid in runoff

G Specially-engineered cone — reduces back pressure and boosts air performance

H Blade computer matched to tweak-out maximum efficiency

H Pulley-diameter/belt-style combination computer optimized to maximize air flow without overloading motor

J Extra-deep orifice opening accelerates air flow

BOX EXHAUST FAN

Economical Ventilation

K Blade computer matched to tweak-out maximum efficiency

L Pulley-diameter/belt-style combination computer optimized to maximize air flow without overloading motor

M 1" x 2" zinc-plated, wire-mesh discharge guard

N Aluminum Shutters — panels linked to prevent flapping

REMEMBER — the higher the efficiency (CFM/watt), the lower your monthly electric bill. The higher the air volume (CFM), the fewer fans you'll need to buy. Don't make the mistake of buying an inefficient, low-volume fan when you can have a top-rated Loyal fan for less money!
