Maintenance
Regular and systematic inspection of all fan parts is the
key to good fan maintenance. Frequency of inspection is
determined by the severity of the application and local
conditions. Once a maintenance schedule is established,
it should be strictly followed. Regular fan maintenance
should include the following:
1. Check fan wheel for any build-up of foreign material
or excessive wear from abrasion. Both can cause
vibration which creates a serious safety hazard. Any
build-up of foreign material should be removed. If the
wheel shows excessive wear, replace it immediately.
Cleaning of the wheel should be accomplished, if
possible, without removing it from the shaft. If the
plenum is furnished with an access door, the wheel
can be cleaned through this opening. If no door is
supplied, then the inlet cone must be removed to
expose the wheel. If for some reason the wheel is
“A” dimension (inlet cone to wheel
back plate) must be held. This
dimension is critical to fan per-
formance. “A” dimension shown is
based on 100% wheel width and
must be adjusted if wheel furnished
is other than 100% full width.
removed from the shaft, take note of the “A” dimen-
sion called out in the chart below. This dimension
must be held if the proper performance is to be
maintained.
2. V-BELT DRIVE: Check V-belt for proper alignment and
tension. (See General Installation and Mainten-ance
Manual IM-101.)
3. FAN BEARINGS: Lubricate the bearings as detailed in
the ball bearing lubrication instructions in the General
Installation and Maintenance Manual (IM-100).
4. SCREWS AND BOLTS: Check tightness of all screws
and bolts throughout the assembly
