The panel design is engineered to provide a thermally broken
construction that eliminates all uninsulated direct conduction
paths between the indoor and outdoor environments resulting
in superior thermal performance. 2” thick double wall foam
injected panels with a thermal resistance of R-13 provides
e󰀩cient thermal insulation and no exposed insulation for high
indoor air quality.

Air leakage occurs as inltration or exltration. Inltration
occurs when negative sections draw air in resulting in
unconditioned and unltered air to enter the unit and be
supplied to the building. Exltration occurs when positive
sections leak air out. Air that has already been invested in
for ltration and conditioning is lost and is not supplied to
the building. The low air leakage construction of the Rebel
Applied prevents costly energy from being wasted and poor
indoor air quality by ensuring the air delivered to the space is
conditioned and ltered. Rebel Applied's Ultra-low air leakage
cabinet construction provides air leakage rates less than 0.5%
of design CFM up to 5" of Static pressure and less than 1% of
design CFM up to 8" of static pressure.

Filtration, temperature, humidity control, and sound are all
important considerations when designing HVAC systems
for indoor air quality. The congurability of Rebel Applied
helps design indoor air quality solutions by providing exibile
air handling options for ltration, humdication and sound
attenuation.
• Filtration: Rebel Applied has exible ltration options to
satisfy indoor air requirements from varying space types.
—Pleated Filter Options: MERV 8 or 13 Filtration
e󰀩ciencies in 2" or 4" lters exceed the AHSRAE
62 minimum MERV 6 required to keep the HVAC
equipment clean and operating e󰀩ciently.
—Rigid Cartridge Filters: 98% of the particulate count
in outside air is less than 0.5 µm. For adequate
ltration of these particles a MERV 13 or higher lter
is required. MERV 14 Cartridge lters are 75-85%
e󰀩cient in 0.3-1 µm particle size and o󰀨er a longer
lter life than pleated MERV 13 lters. Rebel Applied
is available of MERV 11,14, 16 Filtration in the draw-
through or nal position
—HEPA Filtration: 99.97% e󰀩cient particle capture;
these lters are used for life-safety protection in
critical care applications like hospitals and clinics.
—Carbon or Gas Phase Filtration: Rebel Applied
can be supplied with other lter media to help
with applications in contaminated ventilation air
environments like air ports or in spaces where odors
may need to be ltered out of the supply air
• Temperature Control: Rebel Applied can be congured
for varying levels of temperature and humidity control in
both heating and cooling operating ranging from staged
capacity control to fully modulating capacity control
designed to provide +/-1°F supply air temperature control.
• Dehumidication/Humidication: Indoor humidity control
is a critical component for occupant health. High humidity
supports dust mites and allergies and can result in
material degradation and mold. Low humidity dry’s out
mucous membranes in humans which increased risk of
illness.
• Acoustics: Daikin Rebel Applied rooftops o󰀨er fan and
air handling congurability to optimize sound for each
application. Perforated Liners and factory mount sound
attenuators provide single source solution to meet space
sound requirements
