Why use Linear Actuators?
Linear electric actuators are a versatile solution that make a reliable, straight forward option for various applications, openings and property types. Here are some of the reasons that linear actuators could be the right choice for you.
Load rating – Linear actuators are designed for heavier loads than chain actuators, making them ideal for heavy roof vents that require more force to operate and lift them.
Opening distance – With opening strokes up to 1m, they are a great choice for openings 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 occassionally 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?
Linear actuators work by driving a rigid rod or shaft from the motor body using one of two opening mechanisms – either a rod or rack and pinion. Chain actuators work in a similar way but with a chain instead.
Because of the way they are designed, linear actuators facilitate an increased push and pull force; but this also increases the size of the linear actuator.
Popular Electric Linear Actuators
At Rocburn we stock a wide range of linear actuator products with different opening strokes and drive mechanisms. If you are unsure of exactly what it is you need, then our knowledgeable team are on hand to help you pick the best product for your requirements or answer any questions you may have.
Aprimatic ST450
The ST450 has a 230v AC motor and a strong pushing force of 450N, making it suitable for most types of rooflights, louvres and domes as well as vertical, louvred and outward opening windows. This model is available in both 180mm and 300mm stroke lengths.
UCS MAX by Ultraflex Control Systems
For use in 230v AC powered systems, these actuators have a 450N force and come in 180mm and 300mm strokes. But, for those that require a longer stroke, we also have a 500mm version with a force of 350N.
The UCS Max benefits from;
- Quiet Operation
- An IP65 Rating
- A powerful Motor
- Different stroke options
- Comes supplied with either a fixed end bracket or sliding bracket which can be positioned anywhere down the motor body
UCS RACK and UCS T-RACK by Ultraflex Control Systems
This rack and pinion actuator is available in 24v DC and 230v AC options.
- The 24v DC has push/pull force of 650N/350N
- The 230v AC motor has a 750N/650N pull force
Available in 180mm, 350mm, 550mm, 750mm or 1000mm, this linear actuator has a high IP55 ingress protection rating and can be mounted with a sliding bracket.
Multiple Actuators on a Single Vent
Some linear actuators like the UCS RACK have features that allow you to link actuators in tandem to give you an additional push point against the vent. This works by using a connecting rod between the motor and an additional rack mechanism. This auxiliary mechanism doesn’t have a motor, so it relies on the single motor to drive both points and doesn’t improve the force that can be applied.
For heavier vents we’d suggest something like a UCS T-RACK which has motors that support synchronisation. Whilst these don’t have support for a connecting rod, the motors can communicate to keep themselves synchronised.
Frequently Asked Questions
Automated window control provides many great benefits, including;
- Can help to cut costs by delivering effective natural ventilation and reducing reliance on expensive air conditioning bills.
- A greener option that helps companies to use less energy.
- Guaranteed safety with no need for manual operation
- Can be installed with sensors for multiple functions including smoke ventilation, regulating airflow, temperature control and rain sensors.
Extremely convenient and can be controlled at the touch of a button.
Linear actuators are widely used for controlling different types of windows and openings to maintain optimal temperatures, provide natural ventilation and effective smoke control. They can be used on – louvre, highlight, sash and top-hung outer windows but are predominantly used for heavier windows and openings such as rooflights, domes, vents and roof hatches.
Your requirements such as the weight of the window, its type, application and the opening stroke length will determine the type of actuator which will be most effective. If you need any help at all determining which actuator is best suited to your needs, then please get in touch and one of our advisors will be happy to help.
We understand that it can be near impossible to know if a product is compatible with any particular window. That’s why we provide a free consultation over the phone with our technical sales team.
We’ll work with you to offer you the right product for your requirements.
