Dry Running Tri-Lobe Air Positive Displacement Blower
NX Series: High-Performance Positive Displacement Blower For Air Applications
This range of Positive Displacement Blower offers high performance and reliability for neutral gas or air applications. Choose the perfect blower from a wide range of products.
After many years of building rotary lobe blowers, we've created a new design for bare shaft machines. This design offers:
-
better assembly,
-
long-term reliability,
-
cost-effectiveness,
-
and can easily replace our previous range of blowers (SNH – SNV blowers).
What are the main advantages of NX positive displacement blower between other technologies?
-
Constant Volume Output: They give a steady airflow even when pressure changes, which is good for consistent tasks.
-
Adaptable: They work well in both low-pressure situations and vacuum, so they fit many applications.
-
Energy Efficiency: They are often more energy-efficient than other technologies, especially in applications where a constant volume of air or gas is required without the need for frequent adjustments.
-
Low Maintenance: Positive displacement blower typically has fewer moving parts, leading to lower maintenance requirements and longer service life compared to some other compressor types.
-
Accept Dirty Environments: Many industries use them in dusty or dirty environments without compromising performance.
This series of positive displacement blowers is typically integrated into our SilentFlow package offering a turnkey solution for applications involving air or inert gases.

How does NX series Positive Displacment 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
