4 BSB Series BSB Series Single Inlet entrifugal Fans Backward wheels The BSB series is SIS centrifugal fans with high efficiency non-overloading backward curved impellers. The fans are suitable for supply or exhaust applications in commercial, process and industrial VA systems. Sizes of this series are in accordance with AMA standard R20. Type / Operating imit Each fan type has its maximum operating speed and power due to its mechanical design. The operating limit of different fan types of BSB series is set according to the requirement of class I, II and III limit as defined in AMA standard The BSB series is available in type, T, X, Z, U or P. Model 315 to 630 Type -U-P I Model 710 to 1400 Type T-U-P II I Model 1600 to 2000 Type X-U-P III II II Type Z-U-P III III Type This type has a frame fitted on both sides of the fan, providing better strength and rigidity.

5 BSB Series TENIA SPEIFIATION heel The wheel of BSB series is made of cold rolled sheet steel backward curved blades with polyester powder coating finish. ousing For all sizes except 1250 and above, the housing is manufactured in galvanized sheet steel with the housing fixed to the side plates in "pittsburg lock" form system. ousing for 1250 and 2000 are manufactured in mild steel finished with polyester powder coating. Fully welded steel plate housings with painted finish are available for all sizes upon request. Frame The frame is manufactured with galvanized angular bars for type "". For type "T", "X", "U" and P, they are manufactured with sections of steel with polyester powder coating finish. Shaft Shafts are manufactured from 45 carbon steel using an automatic process for positioning and cutting of the keyways. All dimensional tolerances of the shaft are fully checked to ensure a precision fit. All shafts are then coated with an anti-corrosion varnish after assembly. Bearings Bearings used are either deep groove ball bearing type with an adapter sleeve, or spherical roller bearings sealed at both sides for different duty application and are classified as below: Fan Type Mounted in a rubber housing Mounted on cast iron supports with grease point T X U M Medium Duty TM Medium Duty XM Medium Duty UM Medium Duty Bearing Duty eg. Model: BSB 450 M TX Extra eavy Duty XX Extra eavy Duty UX Extra eavy Duty Fan Bearing Duty (M, X) Fan Type (, T, X, Z, U) Fan Size (315, 355, ) Except TX, XX, UX extra heavy duty bearings, all bearings are lubricated for life and maintenance-free. If re-lubrication is necessary, it is recommended to use a lithium base grease suitable for all temperatures within the operational limits. For type P bearing, please consult your nearest Kruger office for details. 3

6 BSB Series Balancing Quality All wheels are statically and dynamically balanced to ISO1940 and AMA 204 G2.5 standards. All fans after assembly are trim-balanced to ISO1940 and AMA G2.5 standard. lean room application fans with balancing grade of G1.0 are available upon request. AESSORIES P3 asing Drain This option is available when using fans exposed to the atmosphere or operating in high humidity conditions. Outlet Flanges Outlet flanges are available upon request. P4 Inlet Flanges This option are set against the fan to facilitate installation. It is available in 2 types- flange or U flange. P5 Inspection Doors The inspection door can be supplied upon request. It can be supplied in one of the three positions (P3, P4 & P5). Guards Inlet guards, discharge guards and non-drive end shaft guards are available on request. Fan Rotation and Discharge The rotation and discharge of the fan is in accordance with AMA standard The direction of rotation is determined from the drive side of the fan :- - clockwise rotation - counter-clockwise rotation Motor Position The position of the motor for belt drive centrifugal fan is in accordance with AMA standard ocation of motor is determined by facing the drive side of fan and designated by letters, X, Y, or Z. 4

7 BSB Series orrection Factor, % motor power output Pole 4 & 6 Pole Motor Selection The power curves shown on each performance graph represent the absorbed power at the shaft of the fan measured in k. To determine the power of the motor to be installed, a correction factors should be applied to compensate for transmission losses. For conversion to horsepower (P), use multiplying factor Motor power output (k) Dynamic Pressure Both dynamic pressure and outlet air velocity values shown on each graph are calculated base on the full discharge area, i.e. ducted outlet conditions. ith free outlet conditions the velocity pressure is higher. To determine this new value, multiply the velocity pressure of the ducted outlet obtained from the fan curve by the following correction factor K. K = 1.67 Fan performances calculated with this correction factors are not licensed by AMA. Performance The performance data shown on each graph is derived from tests conducted in accordance to AMA Standard 210 Fig 12 installation type B (free inlet and ducted outlet condition). Ratings refer to the standard air density with the total pressure as a function of the air volume, using logarithmic scales. It is essential that the same installation type and test standards are used at all times when comparing fan performance. Noise The noise levels shown on each graph refer to the "A-weighted" sound power values and the data on the inlet side has been measured in accordance with AMA Standard 300 diag. 2 - configuration "B". The noise levels of the fans are determined as follows : Sound power level - ("A" scale): w (A) as catalogue Octave band spectrum: w = w(a) + w rel. db [refer to Kruger for more details] Sound pressure level: a) free field p(a) = w(a) - (20log 10 d) -11 b) room conditions p(a) = w(a) - (20log 10 d) -8 where d = distance from fan (m) 5

8 BSB Series Performance The performance data shown on each diagram is derived from tests conducted in accordance to AMA Standard 210- Fig 12- Installation type B (free inlet and duct outlet condition). Ratings refer to standard air density with the total pressure as a function of the air volume, using logarithmic scale. It is essential that the same installation type and test standards are used at all time when comparing fan performance. According to AMA 205, BSB series can be classify as FEG 80~85 based on fan peak efficiency. The following is the explanation of FEG classification: 1. Fan size is the impeller diameter in mm. 2. The fan peak efficiency shall be calculated from the fan (total) pressure. 3. If this method is used for a direct driven fan, the fan efficiency is the impeller efficiency. 4. The FEG label for a given fan size is assigned when the fan peak efficiency is equal to or lower than the efficiency at the grade upper limit, and higher than the efficiency at the grade upper limit of the next lower grade for the fan size. 5. For any fan sizes larger than 1016 mm, the values of the grade upper limits are the same as for a size of 1016 mm. 6. No labels are considered for the fans with the fan peak total efficiency below FEG The values of efficiencies are calculated for fan sizes in the preferred R40 Series. 8. Not all available fan sizes are shown. Fan Efficiency Grades (FEG) for Fans without Drives (SI) AMA 205 6
