MOTOR OPERATORS
Motor operators offer the most efficient means of operation.
They soon pay for themselves by conserving heat, by more
efficient traffic flow, by savings in man- power. Further,
for frequent or rapid use, remote controlled motor operators
are mandatory. |
| |
| Motor operators are integral
power units engineered for long life and reliability.
For each door or grille requirement, horsepower and gear
reduction are designed conservatively. |

MOUNTINGS (INTERIOR)+
VF mounting (vertical front-of-coil) is standard for
Service doors and steel grilles up to approx. 270 sq.
ft., and for all aluminum Grilles. VW mounting (vertical
wall) is standard for larger steel doors and grilles,
and for all Fire doors.
Optional mountings (HT, HS, HF) are available when
in accord with good engineering practice.
+For doors mounted on exterior face of wall, with operators
on exterior (i.e., types SEM & AEM), the VW mounting
is applied |
