High Output Compressors
With WABCO’s Worldwide Modular compressor design (WWM), a new standard has been set for compressors in the commercial vehicle industry. The WWM concept is WABCO’s approach to a worldwide standardized compressor design, thus enhancing cost effectiveness and speed to market. This highly modular design has found appreciation with our global customers who are able to tune their compressors with different performance levels and features by application and/or by market. Combinations of existing and released parts out of global resources offer the possibility to be responsive to specific customer requirements.
Today’s design of WWM compressors is based upon a 85 mm piston diameter. WABCO`s answer to customers growing demand for compressed air is the High Output (HO) compressor using a 100 mm piston diameter which increases the free air delivery. This addition seamlessly closes the gap between the current 85 mm based single and twin cylinder compressors, as can be seen in the table below.
| Single cylinder HO Compressor | Twin cylinder HO Compressor | |||
| Piston Ø 100 mm | Piston Ø 100 mm | |||
| Swept volume (in cm³) | Air delivery at 12.5 bar, 3000 min-1 (in l/min) | Swept volume (in cm³) | Air delivery at 12.5 bar, 3000 min-1 (in l/min) | |
| 330 | 575 | 660 | 1.150 | |
| 393 | 680 | 786 | 1.370 | |
| 440 | 765 | 880 | 1.530 | |
- Design based on WABCO’s Worldwide Modular compressor concept which has reliability and durability in the market
- New developed piston with 100 mm diameter
- Swept volume can be easily and quickly adapted from 330 cc up to 440 cc for a single cylinder compressor, and 660 cc up to 880 cc for twin cylinder compressor.
- Usable for both single stage and two stage compressors
- Optional features;
- Temperature Reduction system (TR)
- Power Reduction system (PR)
- Tang or Spline through-drive for pump operation
- Turbo-charged inlet air instead of natural aspiration
- Different bearing solutions
Benefits
- Closing the gap between current single cylinder compressors and twin cylinder compressors
- Brings twin cylinder compressor performance in a single cylinder design and can lead to weight and cost reduction and requires less space
- Fuel savings due to minimized power consumption in off load operation (up tp 0,7 liter per 100km)
- Less oil degradation and up to 100°C lower air temperature enabling reduced discharge line length up to 60%
- Can be quickly customized to specific engines and build-in situations (like engine interface, piping, through-drive)
- Production capability available at all WABCO’s global production facilities
Application
- Trucks
- Buses
- Agricultural and special vehicles
Market availability: Africa, Asia, Europe, North America, South America
