R-WVB
Overview
The document presents technical information about the Gardner Denver R-WVB series compact rotary lobe blowers, designed primarily for vacuum operation up to a maximum of 0.5 bar absolute pressure. These blowers are contactless, featuring either two-lobed (WVB 25) or three-lobed (WVB 120 - 8300) rotary pistons, and are available in 16 sizes with capacities ranging from 22 to 8580 m³/h.
Product Variants
- WVB (01): Base unit with free shaft, no motor included.
- WVB (30): Compact unit with integrated motor and components.
- WVB (60): Compact unit equipped with an acoustic enclosure for noise reduction.
Key Features
- Contactless operation reduces wear and maintenance.
- Low noise and pulsation levels due to optimized blower speeds.
- High efficiency and stable mechanical design.
- Service-friendly construction for ease of maintenance.
