The Brochure

Robuschi’s Robox Side Channel Blower is designed for water and wastewater treatment facilities that need reliable, low-maintenance air supply in tight spaces. It’s a direct response to the operational pain points of intermittent or continuous air demand—especially where installation space is limited and downtime is costly.

Unlike traditional lobe or screw blowers, the side channel variant offers contact-free compression, oil-free operation, and a compact footprint. It runs up to 20,000 hours continuously with minimal maintenance, making it ideal for secondary treatment aeration or sand filter backwashing.

Key Features

  • Oil-Free Compression

No lubrication needed. Eliminates contamination risk and meets strict environmental standards.

  • Direct Coupling

Impeller mounted directly on motor shaft. Reduces vibration and noise, improves efficiency.

  • Fixed or Variable Speed Options

Operates at fixed speed or with integrated VFD for plug-and-play flexibility.

  • Compact Design

Fits into constrained spaces. Reduces installation costs and improves process efficiency.

  • Low Noise

Emissions Inlet and discharge silencers plus pulsation-free airflow keep noise levels low.

  • Durable Build

Manufactured in Germany by Gardner Denver GmbH. Rated IP55 with IE3 motors.

  • Performance Range

Flow up to 700 m³/h, pressure up to 600 mbar(g). Available in single/double stage and flow variants.

 

How It Works

  1. Air enters through the inlet port into the rotating impeller.
  2. Centrifugal force pushes air outward, increasing pressure.
  3. Each rotation adds kinetic energy, boosting pressure.
  4. Compressed air exits via discharge silencer.
