Recommended Maintenance
Single Duct Terminal Units supplied with stainless steel
construction are supplied with Celcon
®
bearings as standard.
Bronze oil impregnated bearings and 316 stainless steel
bearings are optional for certain applications. It is
recommended that those units equipped with 316 stainless steel
bearings be lubricated periodically as required by the application
and environment.
A Silicone based lubricant such as DuPont™ Pure Silicone
Lubricant with KRYTOX
®
PTFE or equivalent should be applied
to the shaft between the shaft and the bearing surface to
prevent excessive wear. This can be done without removal of
the shaft by pushing or pulling the shaft in one direction while
using a spray applicator tube to inject lubricant into the small
gap formed on the opposite side.
