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

Discover some specific applications:

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
