Screw Blower Unit

The new Robox Screw blower unit accommodates the state-of-the art CDL airend. The patented screw blower has 3x5 profile rotors designed with wide-diameter shafts to reduce the deformation caused by internal and external loads.

The CDL airend is equipped with seals that use a permanent non-wearing design to extend longevity, and reduce maintenance costs. It also uses high precision and low friction bearings to provide absolute strength and stability on multiple planes to handle extreme applications.

The RSW airend is equipped with a wide-diameter shaft rotor design to reduce the deformation caused by internal and external loads. This ensures that the screw blower unit can work efficiently in even the harshest conditions. The bearings have an increased lifespan thanks to the reduced number of revolutions they have to make. The seals on the conveyed gas and lubricating oil are also “wear-free”. 

Technical informations

A Reactive discharge silencer with increased thickness and spark arrester. This design prevents contamination of conveyed gas with sparks generated from the blower.

Proven and robust VRC check valve specifically designed by Robuschi is now positioned within the device to ensure a quick and easy inspection, and replacement.

This system provides lubrication alternatives for various operating environments. It is a dual splash lubrication system that is simple, reliable and compact. It also provides minimal maintenance without the need for an external oil circuit. A forced lubrication system can also be ordered as an option.

The new powder coated enclosure ensures long lasting protection from corrosion, chemicals and the environment. In addition, the noise enclosure’s structure is equipped with tight-fitting frames for the doors and roof support.

The new hood design inhibits noise emissions thanks to the enclosure’s air inlet and outlet ducts which are muzzled with a lined single-chamber plenum and lined bends.

The new touch screen controller, Robox Connect, is very user friendly with an intuitive menu. It provides you with a real-time view of the blower unit’s operation, and allows you to continuously monitor the device.
