What is a Tubeaxial Fan? 5905 Items
A Tubeaxial Fan (FAN,TUBEAXIAL) is a nonpositive displacement mechanical device without guide vanes and having an axial fan impeller inclosed within a tubular housing. It is designed primarily for duct installation to move air or gas axially over a wide range of volumes at medium pressures.
What is a Vaneaxial Fan? 4065 Items
A Vaneaxial Fan (FAN,VANEAXIAL) is a nonpositive displacement mechanical device with guide vanes and having an axial fan impeller(s) inclosed within a tubular housing. It is designed primarily for duct installation to move air or gas axially over a wide range of volumes and pressures.
What is a Centrifugal Fan? 7327 Items
A Centrifugal Fan (FAN,CENTRIFUGAL) is a nonpositive displacement mechanical device having a centrifugal fan impeller inclosed within a housing. It is designed to move air or gas over a wide range of volumes and pressures. The air or gas is drawn in axially and discharged radially or drawn in radially and discharged axially by centrifugal force through an outlet in the housing.
What is a Ventilating Fan? 4059 Items
