General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The product may only be used as set out in
the assembly and operating instructions. The
guarantee is only valid if the product is used

with the instructions.
Application area
The PA3500 air curtain unit is supplied
without heating, with electrical heating or hot
water heating.
PA3500 is intended for entrances and
smaller doors up to 3.5 metres in height.
PA4200 is intended for larger door ways and
industrial door up to 4.2 metres in height.
Protection class for units with electrical
heating: IP20.
Protection class for units without heating and
units with water heating: IP21.
Operation
Air is drawn in at the top/rear of the unit
and blown out downwards/outwards so that it
shields the door opening and minimizes heat
loss. To achieve the optimum curtain effect
the unit must extend the full height/width of
the door opening.
The grille for directing exhaust air is
adjustable and is normally angled outwards to
achieve the best protection against incoming
cold air.
The efficiency of the air curtain depends
on the air temperature, pressure differences
across the doorway and any wind pressure.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.
Assembly and operating instructions
Mounting
The air curtain range includes possiblities
for horizontal installation and for vertical
installation and the units can also be installed
recessed into suspended ceilings.
Horizontal mounting
The air curtain unit is installed horizontally
with the supply air grille facing downwards
as close to the door as possible. Minimum

For the protection of wider openings, several
