About Air Cooled Roots Blower

Air Cooled Roots Blower Product Description

The Air Cooled Roots Blower is a type of positive displacement blower designed to handle air or gas with consistent volume and pressure. It operates on the roots principle, using two rotors that rotate in opposite directions to trap and push air efficiently. This blower is ideal for a wide range of industrial applications where oil-free and continuous air flow is essential.

Key Features:

Cooling Type: Air-cooled; no external water cooling system required
Oil-Free Air Delivery: Lubrication is isolated from the compression chamber
Flow Range: 10 to 5000 m /hr (customizable)
Pressure Range: Up to 1 kg/cm (0.1 MPa or 1 bar)
Vacuum Range: Up to 500 mmHg (for vacuum applications)
Noise Level: Low noise with silencer and acoustic enclosures (optional)
Drive Options: Belt-driven or direct-coupled
Construction Materials:
- Housing: Cast Iron / Aluminum
- Rotors: Ductile Iron / Steel
- Bearings: Heavy-duty ball or roller bearings
Mounting: Horizontal or vertical orientation
Lubrication: Oil splash lubrication at both ends
Cooling System: In-built fins and airflow for natural heat dissipation

Applications:

Wastewater Treatment (STP/ETP aeration)
Cement and Fly Ash Conveying
Pneumatic Conveying Systems
Aquaculture and Fish Farming
Electroplating and Galvanizing
Air Supply for Combustion
Vacuum Lifting and Packaging Machines

Advantages:

Rugged and durable construction
Easy to install and maintain
Energy efficient performance
Compact and air-cooled no need for water lines or cooling towers
Suitable for continuous operation under heavy-duty conditions

Superior Durability and Construction

Engineered from cast iron and alloy steel, the Air Cooled Roots Blower features case-hardened rotors and an anti-corrosive epoxy coating for long life even in harsh environments. The robust design and precision machining ensure high reliability and consistent performance across various industrial settings.

Efficient and Flexible Operation

With a wide flow rate range (20 m/hr to 5000 m/hr), adaptable working speeds, and multiple drive options (direct and V-belt), this blower meets the demands of different processes. Splash lubrication, oil-sealed shafts, and air-cooled technology provide efficient cooling and low maintenance, making it ideal for continuous and demanding operations.

FAQs of Air Cooled Roots Blower:

Q: How does the Air Cooled Roots Blower operate in industrial applications?

A: The Roots Blower works on the principle of positive displacement using three precisely machined lobes. As the rotors turn, air is trapped and pushed through the blower, generating a steady flow at various set speeds. This design ensures consistent air output for processes like aeration, pneumatic conveying, and more.

Q: What benefits does air cooling provide over water cooling in this blower?

A: Air cooling simplifies installation and maintenance, as it does not require external cooling circuits or water sources. This design reduces operational complexity, minimizes the risk of leaks, and enhances suitability for both outdoor and indoor environments.

Q: When should I use a direct drive versus a V-belt drive for this Roots Blower?

A: Direct drive offers higher energy efficiency and minimal maintenance, ideal for applications requiring steady speeds. V-belt drive allows more flexibility for adjusting speed and can be beneficial where varying load requirements or ease of belt replacement are factors.

Q: Where can the Air Cooled Roots Blower be installed?

A: This blower is designed for versatility and can be installed indoors or outdoors, thanks to its sturdy construction, anti-corrosive epoxy coating, and weather-resistant features. Always ensure it is mounted on a firm base and protected from excessive dust or moisture.

Q: What process steps are involved in installing and starting this blower?

A: Installation involves securing the blower to a level base, connecting the inlet filter, safety valve, and silencer, wiring the electric motor to an appropriate power supply (220V, 380V, or 415V), and checking oil levels for the splash lubrication system. Once installed, check alignment (for V-belt models), ensure all safety accessories are in place, and start the unit following the manufacturers guidelines.

Q: How is noise kept below 85 dB during operation?

A: The blower uses precision-balanced rotors, a robust housing, splash-type lubrication, and high-quality accessories like silencers to keep noise emissions below 85 dB, supporting safer and quieter work environments.

Q: What advantages does splash lubrication offer in this Roots Blower?

A: Splash lubrication efficiently distributes oil to all moving parts, ensuring smooth operation and extended component life. This method reduces maintenance intervals and keeps downtime minimal, resulting in higher operational reliability.
