VAS HI21

VAS Unique Design Feature:

After engaging ordisengaging shifters, constant pneumatic air pressure is not required in VAS Gearboxesas a separate ball spring assembly is installed in the shifter assembly to LOCKthe shifter shafts after shifting. Pneumatic air pressure is only required toshift (engage or disengage) the shifter shafts, after shifting, pneumatic airpressure can be removed.

Both Driveline throughput(vehicle in motion) and PTO Aux. Applications cannot be engaged (operated) atthe same time. Either the vehicle shall run on the road (Driveline) or in astationary position the PTO Auxiliary Outputs can be engaged. This VAS Uniquefeature eliminates the possibility of an auxiliary application accident whilevehicle is in motion. If Both Driveline and PTO Aux. applications are required(to be operated) simultaneously, kindly refer to our Combination Reductionmodels CR4, CR7 & CR8 series gearboxes which have both driveline & PTOAux. simultaneous options with Reduction Driveline feature.

Durable and Efficient Gear Motor Solution

Engineered with high-quality cast iron and alloy steel, the VAS HI21 stands out for its robust construction and long operational life. The gear motor's precision casting and helical gear profile offer smooth, quiet, and efficient power transmission-ideal for critical industrial processes requiring reliability and low maintenance.

Advanced Engineering Meets Versatile Performance

The VAS HI21 uses synthetic oil lubrication and natural air cooling, keeping the motor running efficiently and prolonging its service life. Its insulation class F and IP55 protection ensure safe operation even in demanding environments, making it suitable for a broad range of uses in conveyors, mixers, and material handling systems.

FAQ's of VAS HI21:

Q: How does the VAS HI21 ensure efficient power transmission in industrial applications?

A: The VAS HI21 uses a coaxial inline helical gearing arrangement with a precision helical tooth profile, providing high torque output and smooth, quiet motion. Its efficiency can reach up to 96%, ensuring minimal energy loss during operation.

Q: What are the main benefits of using synthetic oil lubrication in the VAS HI21 gear motor?

A: Synthetic oil lubrication minimizes friction and wear, extending the lifespan of the gear components and reducing the need for frequent maintenance. It also enhances overall gearbox performance, especially during prolonged industrial use.

Q: When is the VAS HI21 most effectively deployed in industry?
