Why use Linear Actuators?
Load rating – Linear actuators are designed for heavier loads than chain actuators. So they are ideal for roof vents where more force is required to operate the vent.
Opening distance – With opening strokes up to 1m, they are a great choice where a large amount of airflow is required from the vent.
Ingress Protection – With high IP ratings, generally exceeding IP55. They can be installed in areas that may be ocassionally exposed to weather or for dusty industrial environments.
We have a wide range of linear actuators in stock and ready for next working day delivery.
How do Linear Actuators differ from chain actuators?
These work by driving a rigid rod or shaft from the motor body instead of a chain. Whilst this does afford an increased push and pull force, it also increases the size of the linear actuator.
