ALM aluminum multi-blade dampers

ALM multi-blade air dampers are a miniature version of SMAY multi-blade louvered air dampers. They are designed for fitting
in ventilation and air conditioning systems, especially in air handling units and automation systems for precision control
of airflow.
ALM dampers are excellent closing devices. They can be used
in systems that have special requirements such as heat recovery systems (multi-section dampers),or to protect air heaters from the effects of frost, and to release smoke during a fire.
Working temperature (-40°C to +90°C).
