Abstract

The present invention relates to the field of field of air ventilation systems and air conditioning systems used e.g. in homes, in businesses, in hotels, in passenger vessels and in hospitals, and more particularly to a method for maintenance of an exhaust air ductwork and an apparatus for accessing an exhaust air ductwork. An apparatus for accessing an exhaust air ductwork whilst said exhaust air ductwork is in use according to the present invention has a suction chamber suitable for fitting airtight around an outlet valve of an exhaust air duct, which suction chamber has at least one airtight lead-in (5), (9), through which at least one airtight lead-in (5), (9) the exhaust air ductwork can be accessed, a pair of airtight arranged work gloves (10) suited for manual removal of the outlet valve of an exhaust air duct, an air pressure measurement device (11) suited for measuring the air pressure of the exhaust air duct, and a connection (6) for an adjustable suction fan, which connection (6) has an adjustable valve (7) suited for regulating the suction air pressure of the exhaust air duct when said suction fan is not in use.
