NX Bareshaft Positive Displacement Blower For Air

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

Engineered by Hibon after decades of experience designing a wide range of industrial products, the NX Series positive displacement (PD) blowers represent the next generation of rotary lobe technology.

 

This new bare‑shaft rotary lobe blower design improves assembly efficiency, increases reliability, and fully replaces legacy SNH and SNV blower models.

The NX Series is designed for tough industrial processes where consistent performance and durability are critical. Each blower is equipped with a robust lobe rotor design that delivers:

  • Consistent airflow
  • Stable air pressure
  • Constant volume performance

 

The oil‑free design ensures clean operation while supporting long‑term energy savings and reduced operating costs.

These characteristics make NX blowers a dependable solution for continuous‑duty operations.

 

  • Constant Volume Output – Maintains steady airflow regardless of changes in system or atmospheric pressure
  • Wide Operating Range – Performs efficiently in both low‑pressure and vacuum conditions
  • Energy Efficient – Ideal for systems requiring a continuous, stable flow
  • Low Maintenance – Fewer moving parts increase reliability and service life
  • Quiet Operation – Low noise levels improve workplace safety and comfort
  • Rugged Construction – Designed to operate reliably in dusty or dirty environments

SilentFlow Packaged Solutions

Customers frequently select the NX Series blower paired with the SilentFlow package for a ready‑to‑use solution. This packaged system simplifies installation and delivers:

  • Proven efficiency
  • Reliable performance
  • Reduced setup time

The NX Series with SilentFlow is an ideal choice for air and inert gas applications where reliability, simplicity, and performance matter most.

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
