Description
Air curtains produce a wall of continuously flowing air
that acts as a thermal barrier against outside air and
provides protection against insects, dust, odor, fumes
and other contaminant’s and maintains interior
conditioned temperature by preventing heated or
cooled air from escaping through open doorways.
Heated air curtains are engineered to treat incoming
cold air at customers’ entrance areas. Used over front
door entrances, heated air curtains supplement existing
heat to prevent infiltration of colder outside air. Heated
units are not recommended for areas subject to high
winds.

Description
Air curtains produce a wall of continuously flowing air
that acts as a thermal barrier against outside air and
provides protection against insects, dust, odor, fumes
and other contaminant’s. Maintains interior conditioned
temperature by preventing heated or cooled air from
escaping through open doorways.
Heated air curtains are engineered to treat incoming
cold air at customers’ entrance areas. Used over front
door entrances, heated air curtains supplement existing
heat to prevent infiltration of colder outside air. Heated
units are not recommended for areas subject to high
winds.

Description
Air curtains produce a wall of continuously flowing air
that acts as a thermal barrier against outside air and
provides protection against insects, dust, odor, fumes
and other contaminants. Maintains interior conditioned
temperature by preventing heated or cooled air from
escaping through open doorways.
Heated air curtains are engineered to treat incoming
cold air at customers’ entrance areas. Used over front
door entrances, heated air curtains supplement existing
heat to prevent infiltration of colder outside air. Heated
units are not recommended for areas subject to high
winds.
