Framed Aluminum Vent Panel
Laird's patented MaxAir vent panel product line provides
an innovative cost effective approach for providing
increased airflow and EMI protection for
telecommunications hardware equipment such
as fans and server racks.
This metallized polycarbonate honeycomb material
provides a rigid medium eliminating the need for costly
frame designs. This frameless design allows greater airflow
through the entire honeycomb surface and ease of
installation through its press-to-fit assembly. The MaxAir
vent panel provides greater durability and flexibility than
traditional aluminum vent panels.
Varying densities of material are available to meet specific
levels of rigidity requirements. The honeycomb cell size can
be 0.125 in (3,18mm) or 0.250 in (6,35mm) in standard
thicknesses of 0.250 in (6,35mm) and 0.500 in (12,70mm).
MaxAir
TM
• Metallized polymeric honeycomb provides excellent product
rigidity and dent resistance
• Eliminates frames, rivets and costly labor to install
• UL 94 V0 rated or intumescent coated versions available
for flame resistance
• Increases useable air flow area by 10% to 20% compared to
framed aluminum vent panels
• Special features can be machined into honeycomb, such as
recesses and rabbet cuts to customize panel
• Half the weight of traditional aluminum honeycomb
vent panels
• Compressible conductive perimeter gasket provides extensive
tolerance to accommodate variations in shelf widths or vent panel
opening dimensions
• Can be manually inserted with slide-in motion or by
compression fit utilizing compression stops and minimal
hardware
APPLICATIONS:
• Telecommunications hardware equipment
• Fans • Military applications
• Server racks • Shielded rooms
