Dust-exhaust fans of DRF-7-40 type are widely used in general purpose air ventilation systems, in dust-trapping units, in granular material pneumatic conveying systems, in grain processing lines, in dust-loaded air bleed systems within cement and reinforced concrete structure production. Also these fans are used for wood chips and saw-dust removal, for metal dust suction, for slag and dust removal in welding industry and for other industrial and sanitary-engineering purposes. These medium pressure fans are manufactured in right-hand and left-hand rotations with radial blades. In accordance with the field of application these fans can be produced in the following modifications:
- general purpose industrial modification (carbon steel)
- corrosion-resistant modification (stainless steel)
- corrosion-resistant modification (titanium alloys)
