Three Lobe Roots Blower – Working, Types, Price & Benefits
When industries need a machine that can move large volumes of clean air with stability and reliability, one piece of equipment stands out almost everywhere you look: the Three Lobe Roots Blower.
Known in many places as a Tri Lobe Roots Blower or a 3-lobes roots type blower, this design has become the gold standard for low-pressure industrial air supply.
Whether you’re running a wastewater plant, operating a pneumatic conveying system, managing aquaculture tanks, or handling material movement in cement and chemical plants — a Three Lobe Roots Blower is likely one of your most important assets.
But purchasing one isn’t always easy.
People often have questions like:
- How does a Three Lobe Roots Blower work?
- What are its advantages over other blowers?
- What are its types and applications?
- Which manufacturer offers reliable quality?
- What affects a Three Lobe Roots Blower price?
What Exactly Is a Three Lobe Roots Blower?
A Three Lobe Roots Blower is a positive displacement air blower that moves air by trapping a fixed volume and pushing it through the outlet using two rotors.
Each rotor has three lobes, and they rotate in opposite directions without touching each other.
What makes this machine powerful is its ability to deliver:
- Constant airflow
- Oil-free air
- Low noise and vibration
- High efficiency
- Long service life
It’s basically the upgraded version of traditional twin-lobe blowers. The extra lobe increases stability, reduces pulsation, and improves energy savings.
In simple language:
A Three Lobe Roots Blower pushes air steadily and reliably without compressing it inside the machine. Compression only happens at the outlet due to system resistance.
How the Three Lobe Mechanism Works
The working principle is surprisingly simple, even though the engineering behind it is advanced:
Air enters through the inlet section.
The two tri-lobe rotors rotate in opposite directions.
The rotation traps air between the casing and the lobes.
The trapped air moves from the inlet side to the outlet side.
The air is released at constant volume and pressure.
There’s no internal compression, no oil inside the chamber, and no direct contact between the moving parts, which is why these blowers are long-lasting and low-maintenance.
Key Benefits of the Three Lobe Design
There’s a reason industries around the world have moved from two-lobe to three-lobe blowers. Here’s what that third lobe improves:
1. Reduced Pulsation
Air comes out more smoothly, without pressure jumps or vibration.
2. Lower Noise Levels
The unique lobe angle minimizes turbulence and mechanical sound.
3. Higher Efficiency
Better sealing and lower leakage translate into energy savings.
4. Less Wear & Tear
Non-contact rotors last longer, and bearings remain stable.
5. Better Heat Control
Reduced friction leads to lower heat buildup during long operations.
6. Suitable for Continuous Use
Perfect for industries that run 24/7 operations like wastewater aeration.
In short, the three-lobe design makes the machine quieter, smoother, and more efficient — an all-round upgrade.
Different Types of Roots Blowers
Although Three Lobe Roots Blowers dominate the market, it’s good to understand all available types so you can choose the right model for your application.
1. Two-Lobe (Twin Lobe) Roots Blower
- Older technology
- Higher noise and pulsation
- Less efficient
- Mostly used in old installations
2. Three Lobe Roots Blower
- Modern standard
- Best combination of efficiency, cost, and durability
3. Air-Cooled Roots Blower
- Uses ambient air for cooling
- Good for low to medium pressure
- Common in aquaculture & small industrial setups
4. Water-Cooled Roots Blower
- Uses water jackets for cooling
- Ideal for high-pressure or high-temperature applications
- Handles long duty cycles better
5. Vertical Roots Blower
- Rotors are vertical
- Helps save floor space
- Easy for small plants or compact areas
6. Mechanical Vacuum Booster (Roots Vacuum Pump)
- Works with vacuum pumps
- Boosts vacuum levels
- Used in chemical, pharma & drying units
Understanding these helps you pick the best blower for your plant instead of buying something that doesn’t match your pressure or flow needs.
Complete Applications of Three Lobe Roots Blowers
One of the biggest strengths of Three Lobe Roots Blowers is that they work in almost every industry that needs a stable flow of air or gas.
Here are the most common applications:
1. Wastewater Treatment Plants
In aeration tanks, bacteria need oxygen to break down waste.
Roots blowers supply that oxygen continuously, making them essential in:
- STPs (Sewage Treatment Plants)
- ETPs (Effluent Treatment Plants)
- Industrial wastewater systems
The stability of a Three Lobe Roots Blower ensures efficient biological treatment.
2. Pneumatic Conveying
Industries use air pressure to move powders and granules.
Three Lobe Roots Blowers support conveying of:
- Cement
- Fly ash
- Plastic pellets
- Sugar
- Flour
- Chemicals
Their pulse-free flow prevents blockages and material damage.

Advantages That Make Three Lobe Roots Blowers Popular
Let’s break down why so many industries prefer this type of blower:
✔ High Efficiency
Better rotor design = lower energy consumption.
✔ Quiet Operation
Silencers and design geometry reduce noise significantly.
✔ Low Maintenance
Few moving parts, no internal friction, no oil contamination.
✔ Longer Machine Life
Heavy-duty construction and minimal wear guarantee long service life.
✔ Stable Performance
Constant airflow means stable plant operations.
✔ Handles Harsh Conditions
Can run for thousands of hours with proper care.
✔ Great for Continuous Operation
Ideal for plants that run 24/7 — wastewater treatment, cement, chemicals.
These advantages explain why Three Lobe Roots Blowers have replaced older twin-lobe designs in most modern facilities.
What Impacts Three Lobe Roots Blower Price?
If you’re searching for the best Three Lobe Roots Blower price, it’s good to know what factors influence the cost:
1. Capacity & Pressure
Higher CFM or m³/hr output = higher cost.
Higher pressure (upto 1 bar or more) also increases price.
2. Air-cooled vs Water-cooled
Water-cooled models are more expensive due to extra cooling components.
3. Material & Build Quality
Cast iron, SG iron, or steel casing impacts price.
4. Included Accessories
Silencers, filters, safety valves, base frame, motor, and belts add to cost.
5. Custom Requirements
Industries needing corrosion resistance, high-temperature handling, or explosion-proof designs will pay more.
6. Brand Reputation
A reliable blower from a trusted manufacturer costs more upfront but saves money in maintenance and downtime.
7. After-Sales Support
Companies offering strong customer support often price their products slightly higher—but they save you stress later.
Understanding these factors helps you compare prices more intelligently.
Why Manufacturer Selection Matters
Your blower will run for thousands of hours per year.
A poorly built machine will:
- Consume more electricity
- Overheat
- Vibrate heavily
- Fail frequently
- Interrupt plant operations
A well-built, precisely engineered unit delivers the opposite experience: reliability, efficiency, and peace of mind.
That’s why choosing the right Three Lobe Roots Blower manufacturer matters more than people think.

How to Select the Right Three Lobe Roots Blower
Choosing the right blower isn’t just about power — it’s about compatibility with your application.
Here’s a simple checklist:
1. Identify Your Airflow Requirement
Know your CFM or m³/hr needs.
2. Understand Your Pressure Requirement
Most systems need between 0.3 and 1 bar.
3. Choose Cooling Type
- Air-cooled for general use
- Water-cooled for heavy-duty, high-pressure systems
4. Look at Noise Levels
A plant with workers nearby should opt for silencers and vibration control.
5. Consider Energy Efficiency
The right blower will save thousands in electricity costs yearly.
6. Evaluate the Build Quality
Heavy-duty materials always last longer.
7. Check Service & Spare Availability
A blower is only as good as its support system.
8. Compare Prices Wisely
Go for value, not the cheapest option.
Following these steps helps prevent mismatch, breakdowns, and long-term cost overruns.
