this range of Positive Displacement Blower offers high performance and reliability for 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.

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.
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.
