LTI Ventilatoren certifies that the BSE series shown herein is licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and AMCA Publication 311 and comply with the requirements of the AMCA Certified Ratings Program.
BSE SERIES PRODUCT OVERVIEW
The BSE series are a series of single inlet backward curve centrifugal fan with non-overloading characteristics. Developed with the latest available German technology, there are 12 models
available for selection. These ventilation fans are efficient, have low noise operation and are green for the environment. They are suitable for use in a wide variety of ventilation applications.
TECHNICAL SPECIFICATION
BSE series centrifugal fans consists of a scroll, impeller, frame bearing, shaft, inlet and outlet flange.
HOUSING
The scroll housing is made of galvanized steel sheet. Its side plate has an aerodynamic outlet for efficient air flow and the scroll plate is fixed upon the side plates by electric spot welding. All housings have lubricating bore holes for the possibility of secondary lubrication. A synthetic stopper is used to seal the holes for protection.
The inlet flange are made of high grade cold-rolled sheet and finished with a polyester powder coat. The outlet flange is made of galvanized steel. The connections of the flange components to each other and to the scroll are made using a TOX non-welding process. This maintains a smooth consistent appearance without sacrificing strength and rigidity.
IMPELLER
Backward curve radial impellers are made of high grade cold rolled steel sheet coated in polyester finish.
Numerous CAD/CAM testing were done to ensure optimal rigidity and air performance. All impellers are welded and are both statically and dynamically balanced on special balancing machines according to quality standard Q 2.5 of VDI 2060.
FRAME
The frames for the type R version are made of galvanized steel angle iron bars. The cutting and bending of the frame parts, as well as TOX connections, are formed with the use of molds to ensure consistency and rigidity; the frames for type E and type C versions are welded by an angle steel and flat steel. All frames are finished with a polyester coating to protect against corrosion.
BEARINGS
High-quality grooved ball bearings are used in all BSE series centrifugal fans. The bearings are pre-lubricated, sealed and self-centering. For type R ventilators, the bearings are mounted to the shaft with an eccentric collar; a shock-absorbing rubber ring is inserted between the bearings and the supporting bracket to reduce noise and vibration. Type E and type C ventilators have self-aligning pillow block ball bearings
