LTBM series double volute forward belt drive centrifugal fan is comprised of connected volute and impeller of two sets of double inlet centrifugal fans, with one motor used to drive two sets of impellers through belt drive at the same time. The structure greatly reduces the volume of the whole machine and can obtain a large ventilation volume in a small installation space.
Compared with one volute and one impeller, double type has performance of airflow ×2, speed×(1～1.05), axial power×2.15, noise+3.
Standard Performance Range
Airflow: min 1,606 CFM ～max 37,961 CFM ( 2,700 m3/h～63,800 m3/h, 95349.62 ft³/h~2,253,076 ft³/h)
Static pressure: 0.96~5.34 inches w.g. (240～1,330 pa)
In the field of agriculture, this series can be applied for seed drying, dust removal, grain conveying and drying, general transportation and storage ventilation, material transportation ,storage of fruits and vegetables, livestock ventilation, refrigeration equipment.
In automotive industry, this series can be applied for vehicle exhaust, plant ventilation, welding smoke exhaust, dust collection, air supply & exhaust in paint finishing room.
Such as LTBM250M-4 is double volute forward belt drive centrifugal fan, blade diameter 250mm with medium width, motor poles 4.
This series has one motor to drive two sets of volute and impeller. Should attention its installation rotation direction and air outlet angle.
*** The default rotation direction of our centrifugal fans is CW. If users want different rotation directions, must point out clearly at the time of ordering. ***
