Our combined offering also includes heavy duty blower options and advanced industrial air blower systems for demanding applications. Additionally, the design flexibility of our rotary blower technology guarantees optimal performance across a wide range of industrial processes.

Low Noise

Low noise emissions are ensured by our new discharge and suction silencer design. In addition, canopy enhancements provide noise reduction thanks to special sound proofing material and upgraded panel thickness. In addition, the enclosure air inlet and outlet ducts are muzzled with a lined single-chamber plenum and lined bends.

Easy Installation

Save time and money thanks to the easy and flexible installation of the new Robox Screw blower unit. Handle the Robox with ease utilizing the rigid base which has dedicated channels for forklifts. Place it on any even surface, with no need for special foundations. Thanks to its compact design, the Robox can be quickly and easily integrated into your existing system.

Accessible Service and Maintenance

The design of this new Robox Screw blower unit ensures that the service points are easily accessible. As a leading industrial blower manufacturer, Robuschi focuses on making maintenance simple and efficient for all users.

To help you see inside, the enclosure side doors are hinged and removable, making it ideal for heavy duty air blower applications and ensuring smooth upkeep for air blower industrial systems.

CDL- RSW – Premium Oil-free Airends

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. This ensures the blower can work efficiently in even the harshest conditions.

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”. The RSW airend is available for the current sizes 2,3 and 5.

New Compact Suction Silencer

A newly designed Silencer is equipped with a dedicated filter cartridge for improved reliability and quicker maintenance. This minimises pressure drops. Noise reduction is provided by a new absorptive and reactive internal resonance chamber design.

Robust Discharge Silencer

A Reactive discharge silencer with increased thickness and spark arrester. This design prevents contamination of conveyed gas with sparks generated from the blower. Costly spark traps are no longer necessary.

Check Valve

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.

Lubrication Systems

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.

State-Of-The Art Noise Enclosure

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. All the panels/doors are independent of each other and easily removable for inspection.

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 closed baseplate is suitable for any type of floor guaranteeing proper noise reduction.

In addition the enclosure provides:

Side-by-side installation
Baseplate equipped with dedicated holes for easy access by forklift
Dedicated access for relief valve inspection and setting to reduce maintenance time
Access for routine maintenance operations from the front/rear/left/right side of the hood
Easy service with rear panel opening without the need to disconnect the process pipe
Electrical cable installation possible both from the top and bottom
