GUIDE SPECIFICATIONS
Commercial Low Profile 8 (CLC08) Air Curtain
SECTION 23 34 33
AIR CURTAINS
Berner Commercial Low Profile 8 Series (CLC08) air curtains (a.k.a.
air doors) are designed applications with low door to ceiling
clearance or pass thru windows. They are suitable for openings up to 8
ft (243.8 cm) high for environmental separation and up to 7 ft (213.4
cm) high for insect control.
Air curtains provide environmental separation at openings by reducing
the infiltration of unconditioned air, fumes, dust, and humidity. At
exterior openings, they can resist winds up to 8 MPH (13 KPH) and are
generally mounted inside the building. During cold seasons warm air
that has risen towards ceiling is recirculated; they can also be used
at interior openings such as doors to coolers or clean rooms. Optimum
protection is provided when units are mounted flush to the wall and as
close to top of door opening as possible. To ensure peak performance
keep air stream free of obstructions. Air curtains may not be fully
effective where negative air pressure exists on one side of door;
contact Berner for additional information.
Series CLC08 model air curtains have 1/5 HP motors. They can be wall
mounted or suspended from the ceiling. Electric heated units shall be
installed indoors only and require – a minimum clearance of at least 6
ft (182.9 cm) between the bottom of the unit and the floor, a minimum
of 4 in (10.2 cm) between the top and ceiling and 1 in (2.5 cm)
between the sides and any combustible material.
Edit guide specification to include only information specific to your
project. Delete or add text, select appropriate bracketed phrases, and
fill in blanks as required. Go to Berner catalog or website to select
specific models and sizes that are required for project and to obtain
data necessary to edit this document.
Coordinate specification with information shown on project drawings
and schedules. In general, drawings indicate locations of air curtains
and switches and special mounting requirements, while sizes and
capacities of air curtains and utilities should be described in
specifications or schedules. Cross check mechanical and architectural
drawings.
