Gibbons Engineering Group helps council cut complaints

Gibbons Engineering Group helped an under-pressure district council settle an embarrassing fan-related noise issue at its Hertfordshire offices.

The council was receiving increasingly negative press because of nearby residents complaining about excessive noise from a centrifugal car park extract fan. They commissioned Gibbons’ HVAC Services division to conduct a detailed survey, followed by full refurbishment of the 20-year-old fan.

Sound-level readings were taken prior to the commencement of works, which began with an equipment survey that revealed balance issues along with severe fan and motor bearing wear. Work undertaken included the removal of guards, drive belts and pulleys, before motor and fan bearings were stripped and replaced.

Once the new pulleys were fitted, laser alignment and belt tensioning were carried out and the fan dynamically trim balanced. Testing showed the fan to once again be in excellent working order, after which a new tension adjuster was fitted to the motor and the unit fully cleaned and painted.

As a result of Gibbons’ refurbishment, the council has appeased its neighbours with a 10dB-12dB noise reduction while extending the life of the fan by between 10 and 15 years.
