NX Bareshaft Positive Displacement Blower For Air

NX Series: Three-Lobe Positive Displacement Blower For Industrial Applications

Hibon engineers developed the NX Series after years of building wide range of products

This new bareshaft rotary lobe blower design improves assembly, increases reliability, and replaces older SNH and SNV models.

We built the NX Series for tough industrial processes. 

Each positive displacement blower features a strong lobe rotor. These perfect blowers are a great choice. They deliver consistent flow rate, stable air pressure, and constant volume of air handling.

Industries use NX PD blowers for neutral gas, inert gases, and air applications like wastewater treatment and pneumatic conveying. 

The oil-free design supports clean operation and long-term energy savings.

Air Blowers Key Features:

  • Constant Volume Output: Delivers steady airflow, even with changing system pressure or atmospheric pressure.
  • Adaptable: Performs well in low-pressure and vacuum conditions.
  • Energy Efficient: Saves energy in systems needing a constant flow.
  • Low Maintenance: Fewer moving parts make it easy to maintain and long-lasting.
  • Quiet Operation: Low noise levels improve working conditions.
  • Durable: Works reliably in dusty or dirty environments.

Customers often use NX blowers in the SilentFlow package. 

This setup offers a ready-to-use solution for air and inert gas applications. It ensures efficiency, reliability, and simple installation.

Range of Applications:

What is this positive Displacement blower used for? 

Positive Displacment blower generates a high volume of air or gas flow, making them well-known in the industry. NX series PD blowers can also operate in a vacuum, creating a low-pressure environment.

  • Pneumatic conveying 
  • Aeration (WasteWater Treatment)
  • Fluidisation 
  • Conveying plastic pellets 
  • Filter cleaning

How does NX series Positive Displacement Blower work?

NX series positive displacement (PD) blower operates by trapping a specific volume of air or gas in a chamber and then displacing it out through an outlet. Here's a simplified explanation of how it works:

  • Intake Phase: The blower's rotating lobes (rotors) create expanding chambers that draw in air or gas from the surroundings.
  • Discharge Phase: As the lobes or rotors continue to rotate, the trapped air or gas is displaced from the chamber and forced out through an outlet, without undergoing compression within the blower itself.
  • Continuous Cycle: This process repeats continuously as the lobes or rotors rotate, generating a steady volume of air or gas flow.

In summary, NX series positive displacement blower works by trapping and displacing a fixed volume of air or gas per rotation cycle, without internally compressing it.

  • Flow: From 100 m3/h to 13,000 m3/h
  • Pressure up to 1 bar eff.
  • Vacuum up to 500 mbar
