However, new hybrid-electric vehicles (HEVs) and fully-electric vehicles (FEVs) demand much more of their sub-systems than their current diesel counterparts. Weight, size, noise and the fuel-source have all been redefined and so must the air compressor package.
Air compressor technology has always played an essential role in powering critical systems such as braking systems, air suspensions and doors, on buses, trains and coaches. Our next generation truck and bus air compressor, the TXO2, is perfectly suited to applications within electric commercial vehicles. Quiet, reliable and easily integrated, the TX02 is designed to meet the requirements of new hybrid and electric vehicles.

Advantages of Rotary Vane Compressor Technology for Hybrid and Electric Vehicles:
Versatile Flow Technology
Vane compressor technology permits a range of optimised speed, power, flow and pressure configurations whilst maximising energy efficiency. Flow rates can be varied depending on the application demand between 90 – 600 L/min.
Specific performance and energy efficiency levels are superior to reciprocating and screw compressors, with the variable flow enabling optimised motor performance. In test, vane compressors are circa ‘Nominal 2.2kW vane compressors are circa 20% more efficient than comparable alternatives’* more efficient than comparable alternatives.
Vane compressor technology benefits from having only one major rotating part with no metal to metal contact due to the hydrodynamic wedge and no gears, belts or pulleys – all of which helps to reduce maintenance costs. Compressed air is produced by a rotating shaft with vanes that are free to move with centrifugal force. The major benefit of this more efficient design is negligible wear on the components, less stress and lower levels of wasted heat.
Industry-Leading Low Noise Levels
A rotary vane compressor is a low noise technology (circa 65 - 69 dBA compared to 75 dBA for competitive designs dependent upon the configuration of the machine) which allows passengers to sit close to its point of use with no need for a special acoustic cover which, in turn, reduces overall equipment cost. Similarly, these low noise capabilities make vane compressor technology ideal for 24-hour city applications, such as inner-city bus transit, where there is a requirement to reduce noise pollution.
Vane technology typically has a final content of <3 PPM, reducing the specification of downstream oil separation. This helps deliver an air cleanliness performance that exceeds competing technologies such as screw compressors.
Additional Advantages of using the Rotary Vane Compressor as part of a package
It is now possible to use a rotary vane package which boasts modular assembly. Some of the industry-leading available packages can be adjusted to accommodate different controllers, voltage modes, and types of motors, making it capable of being integrated into most vehicle air systems.
Size and Weight
Motor/drive and cooling options allow the vane compressor package to be configured to the customer's space envelope. This permits installation in a variety of locations on the vehicles chassis. Weight is further reduced by the use of innovative materials with major castings utilising aluminium alloys with polymer and bronze fittings used to maintain weight and corrosion resistance.
