Abstract

The invention relates to an apparatus for generating negative pressure in a space, especially in a work space designated for construction and/or renovation. According to the invention, the apparatus (1) comprises a chamber (3) and a radial fan (4), said chamber (3) having at least one first opening (31) for introducing air into the chamber (3) from a space (T), said opening being fitted with a first filter (5), and a second opening (32) for expelling air from the chamber, said second opening being connected to an inlet duct (41) of the radial fan (4), in connection with said second opening (32) being a second filter (6), and an outlet duct (42) of said radial fan (4) being connectible to an exhaust duct (7) and outside the space (T).
