Acoustic baffles are basically maintenance-free. They must be checked for damage within major
maintenance work and shall be replaced or properly repaired, if required.
7.5 Maintenance plan
The maintenance intervals specified in
are based on empirical values for normal operating
conditions. They are designed for continuous operation (24 hours / day) in moderate temperate cli-
mates and low dust areas, e.g. in offices or shopping malls. Widely differing operating conditions,
particularly with respect to air temperature, humidity and dust can significantly shorten the inter-
vals.
