General Maintenance

Flexible connections between the fan and duct section

will reduce vibration to the duct and decrease noise.

Mounting the fan on vibration isolators is also necessary

for noise dampening.

The impeller in an axial flow fan must be kept

reasonably clean if it is to perform properly. Fans

handling fresh air for ventilating purposes will seldom

need cleaning. Fans exhausting process air should

be cleaned as required. Dirt or chemical deposits

will usually build up on a impeller evenly, and they

present no problem to performance or operation until

they become thick enough to break away in crust-

like pieces. When this happens, the impeller may

be thrown out of balance and the resulting vibration

could be serious. Accumu-lations of deposits should

be removed by solvent cleaning or scraping. If the

impeller has been coated, be careful not to cut

through this protective covering.

Regular and systematic inspection of all fan parts is a

necessity for good fan maintenance. A general instal-

lation and maintenance brochure (IM-100) has been

supplied with this shipment. It includes fan and motor

bearing lubrication, care and replacement of V-belt

drives and taperlock bushing instructions.
