Roots Tip Blower

Rotary Lobe Roots Blower

A Reliable Solution for Stable Airflow in Industrial Processes

The rotary lobe Roots blower is an industrial air pump operating on the positive displacement principle, capable of delivering compressed or vacuum air at a constant flow rate, even when system pressure fluctuates.
It is an ideal choice for applications that require stable performance, high efficiency, and long operational life in demanding industrial environments.

Operating Principle

The Roots blower consists of two non-contacting rotating lobes (rotors) that rotate inside the blower housing. During operation:

• A fixed volume of air is drawn in through the inlet,

• Trapped within the housing chamber,

• Then pushed toward the outlet and discharged.

Thanks to positive displacement technology, the airflow rate remains nearly constant regardless of pressure variations, making this type of blower essential for pneumatic conveying, water treatment, and various industrial processes.

Why Use a Roots Blower?

Roots blowers do not compress air internally; instead, pressure builds as the air encounters resistance in the discharge line. This provides several advantages:

Oil-Free & Clean Air

Because the rotors do not contact each other or the housing, no lubrication is required inside the air chamber. This ensures:

• Clean, dry, oil-free air

• Contamination-free operation

• Full compatibility with food, pharmaceutical, and chemical applications

Designed for the Toughest Conditions

With a cast-iron monoblock housing, efficient heat dissipation, and heavy-duty bearings, the blower offers:

• Continuous 24/7 operation

• High durability in harsh environments

• Low maintenance requirements

• Extended service life

Key Features

• Airflow capacity from 20 to 20,000 m³/h

• Pressure up to +1500 mbar and vacuum up to –500 mbar

• Low-noise, high-efficiency three-lobe rotor design

• Robust monoblock cast-iron housing

• Precision-machined and heat-treated gear set

• Clean, oil-free air output

Fan – Blower – Compressor Comparison

System	Compression Ratio	Pressure Range	Typical Use
Fan	0 – 1.3	0 – 0.25 bar	Ventilation, air circulation
Blower	1.1 – 2.5	0.15 – 2 bar	Pneumatic conveying, aeration, vacuum
Compressor	> 2	3 – 12 bar	High-pressure industrial applications

This comparison highlights that blowers are the optimal solution for processes requiring medium pressure and constant airflow.
