The product can be used to reduce the air
pressure in the renovated room with plastic
protection parts and air hoses. The room is
sealed off from other areas with plastic walls
and the exhaust air hose is led outside or
into another area.
NOTE
The air in the renovated room should be
exchanged at least three times per hour.
In a room with an area of 30m
of 2.50 m the VAC 800-EC can exchange
the air more than six times per hour with the
new G3 + G4 or G3 + F7 or G3 + G4 + H13

must be used. Please note that only authorised
specialist companies are permitted to work in
areas that contain asbestos!
During operation the machine is normally
operated close to maximum power in order
to ensure sufficient negative pressure.
