Explosion-proof SPIROPLAN® right-angle gear units


You don’t have to sacrifice high speeds for your conveyor applications in potentially explosive atmospheres. Our compact lightweights, the SPIROPLAN® right-angle gear units, are also available in an ATEX version.


The smallest solutions: lightweight and compact, even in the ATEX version


What is special about SPIROPLAN® right-angle gear units is their wear-free gearing. It ensures that the power is transmitted reliably and adjusts the speed in your materials handling system. Of course, it’s also included in the explosion-proof gear unit version: an ATEX-compliant gear unit for equipment category II2GD.


With this gearing, the SPIROPLAN® right-angle gear units deliver output torques up to 180 Nm in the motor power range from 0.12 to 3.0 kW. The steel-steel material combination and the special tooth meshing enable a short gear unit design for space-saving installation of the drives.


It’s the details that make the difference


Thanks to their aluminum housing, these right-angle gear units are real lightweights. Their special gearing and lubrication for life ensure that they require very little maintenance. These gear units are designed for long and reliable operation. No compromises: The SPIROPAN® right-angle gear units are suitable for almost any drive task due to their many design variants.
