 Extruded High
Performance Louvers
Applications
Airline's new generation of high performance louvers offers the
designer an efficient, economical solution for applications which require handling larger
volumes of air through smaller openings. The "HP" louvers are designed with high
free area offering low resistance to airflow in both intake and exhaust modes. These
models are available with standard or water drainable blades as well as in 4" and
6" depths.
These models are also available with a concealed mullion design. To
specify, use a prefix "C" on the model number.

Suggested Specification
Furnish and install, where indicated on the drawings,
Model XWD4-HP Stationary Extruded Drainable Blade Louver, as manufactured by Airline
Products Company, Hagerstown, Maryland. Louvers shall be 4" deep and fabricated from
.081" thick extruded aluminum, alloy 6063-T52. Assembly of members shall be by
welding or with stainless steel fasteners. Blades and jambs will have integral channels
for drainage of water.
Louvers shall meet the following criteria for testing
and performance:
A 48" x 48" louver shall have a minimum free
area of 8.91 ft2 (56%).
The free area velocity at the beginning point of water
penetration shall be 974 fpm.
The pressure drop at this velocity shall not exceed
.12" water gauge.
At an exhaust free area velocity of 1022 fpm, pressure
drop shall not exceed .15" water gauge. |
