Easy maintenance
z
The fan and motor is easily accessible by the divided panel structure.
Structural improvement is attained by making the
bottom panel in two pieces, front and rear.
The internal fan casing is also manufactured in two
pieces, namely upper and lower. The maintenance
of the motor and fan can be easily carried out by
removing the rear panel and the lower part of the
casing while leaving the main chassis installed.
