Boldly Takes a Position Where Others Fear to Tread.

Gruner 328 CS / QS actuators – super-fast running actuators for reliable laboratory ventilation and enabling preventive maintenance.

Safety For Laboratories and Fume Hoods

Gruner super-fast running actuators enable contaminated air to be extracted very rapidly and precisely. For even greater control precision, Gruner has developed its 328 CS and 328 QS super-fast running actuators with fail-safe function. These actuators feature high precision and a runtime of less than three seconds.

he optional serial interface on these super-fast running actuators has five times the resolution of analogue versions, enabling the throttle element to be positioned to a precision of < 0.1°.

On the 328 QS actuators with fail-safe function, communication can be maintained for up to two minutes after power supply interruption. In addition, the design effectively prevents the setpoint value from being affected by electromagnetic interference. At the same time, the increased exchange of data through the digital interface provides great potential in relation to preventive maintenance.
