Air Blowers

The Ingersoll Rand low pressure blower covers a wide range of types and sizes, ranging from small bi-lobe and tri-lobe roots blowers to large multi-stage centrifugal blowers.

Having been distributors of Ingersoll Rand compressed air equipment for almost 40 years, in 2010 RD Dutta & Co. P. Ltd. were also officially appointed as distributors for the low pressure blower range. This makes the RD Dutta & Co. P. Ltd. engineering skills, workshops and regional storage facilities available to both the Compressed Air and Low Pressure users within the UK.

The close working partnership of Ingersoll Rand and RD Dutta & Co. P. Ltd. now brings low pressure systems design capability and direct replacements for Hibon and Hick Hargeaves blowers to local distribution centres throughout the UK.

VP - High Vacuum Package

Download VP - High Vacuum Package

High vacuum without water or oil sealing Hibon air injection positive displacement blower package “VP” are the only dry blowers capable of attaining 28" Hg vacuum/93% vacuum.

They are self-cooling, requiring no vacuum relief valve and are designed for continuous industrial use 24 hours a day. The self-cooling design enables warm gases handling and eliminates or reduces the need for pre-cooling. Theses blowers are very efficient for vacuuming a large variety of products, wet or dry.

Key Features

  • Green solution
    To obtain vacuum in centralised cleaning systems, pneumatic conveying, drying of products, or holding application, with neither oil, nor water consumption, this package is ideally suited.
  • Performance
    Designed for industrial used in continuous 24h/24h, VP Packages are the only dry air cooled solution capable to reach the 28”Hg vacuum / 92% vacuum with limited heat increase.
  • Adaptability
    VP package offers a wide range of possibilities with regard to the intake flow rates, auto-adaptation to the customer’s system and temperature.
  • Reliability
    The air injection ensures the self cooling of the blower without auxiliary fluid. It can run accidently with a closed inlet, without affecting your process.
