How to adjust fan belts
Tightening of
belts Do not tighten the belts too much, as this will wear out the ball bearings and thus
reduce their life time.
Dantherm
recommends Dantherm Air Handling A/S recommends the use of special tools for the tightening of
belts in order to check the values of the table below.
Correct tightening
of belts The deflection (F) on the drawing below must be in accordance with the mm indications
of the table (last column).
The deflection strength of each belt is dependent on the profile type and the distance
between the centres.
Use the drawing and the table to establish the correct belt tightness:
Belt profile (type) Centre distance
(mm) Deflection
strength (kg) Deflection, F (mm)
300-400 7
SPZ-XPZ 400-500 1,5 9
500-600 11
SPA-XPA 600-800 2,7 13
SPB-XPB 800-1000 5,0 15
Procedure Do as follows to adjust the fan belts:
Step Action
