General Installation, Operation and Maintenance Instructions For Aerovent Products
Tu-WAY™ Roof Ventilator
The Tu-WAY™ Roof Ventilator is specifically designed for
either exhaust or supply. The assembly consists of a hood and
base with the fan being an integral part of the base. The unit
is constructed to allow the hood to be raised for easy access to
propeller and motor. An access door in the base provides a
convenient method of servicing the shutter.

Care and Maintenance
Good fan maintenance requires regular and systematic inspection of all fan parts. Severity of the application should determine frequency of inspection.
Regular fan maintenance should include the following:
1. Propeller — The propeller 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 propeller 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
propeller may be thrown out of balance and the resulting
vibration could be serious. The dirt or chemical deposits
should be removed by solvent cleaning or scraping. If the
propeller has been coated, be careful not to cut through
this protective covering.
2. V-Belt Drive — Check V-belt drive for proper alignment
and tension. See General Installation and Maintenance
IM-101 for instructions.
3. Fan and Motor Bearings — Lubricate the bearings (if
belt driven). Bearing lubrication instructions are detailed in
IM-100.
4. Shutters — Periodically check damper blades and remove
dirt accumulation. Bronze damper bearings should be
checked for smooth operation.
5. Screws and Bolts — Check for tightness throughout the
assembly.
