GT-65 Roots Air Blower Review in Bangladesh

Roots blowers are frequently utilized in situations where a sizable amount of air needs to be transported across a narrow pressure difference. This comprises systems that use a Roots blower alone or in conjunction with other pumps to create a high vacuum in low vacuum situations.

Numerous businesses and industrial processes, including pneumatic conveying, use root blowers. Many production and processing processes depend on root blowers. Although technically called "positive displacement rotary air blowers," Roots blowers are most frequently referred to as "blowers."

If you are looking for the best roots air blower in the country, Green Dot Limited is where you should go. This article will provide you with a GT-65 Roots Air Blower review in Bangladesh!

What is a Roots Air Blower?

A Roots blower is an internal-compression-free, valve-less displacement compressor. Compressed air returns into the housing from the pressure side when the compression chamber touches the outlet port. When the compression chamber's volume continues to shrink with sustained rotation, additional compression follows. As a result, compression occurs in full counter-pressure, which harms efficiency and increases noise. A housing has two identical, typically symmetrical, counter-rotating rotors that are synchronized by a set of gear wheels.

Blowers typically have no oil and are air-cooled. Even though two- and three-stage versions are available, their low efficiency restricts these blowers to compression in a single stage and very low-pressure applications. Roots blowers are commonly utilized as pneumatic conveyance devices and vacuum pumps.

The History of Roots Air Blower

Positive displacement (PD) blowers, of which the "Roots" lobe-style blower is a subtype, were developed in the late 1850s by the Roots brothers. Positive displacement blowers work with flow and pressure as independent variables; as a result, the flow rate is essentially unaffected by changes in pressure and speed. Although the Roots blower has been around for more than 150 years, the main development in lobe technology throughout this time has been concentrated on reducing noise rather than increasing efficiency. Bi-lobe blowers produce waves with a very high amplitude at a low frequency; a third lobe was added to decrease the amplitude and raise the frequency of the waves.

How Do Roots Air Blowers Work?

Roots blowers are typically air-cooled, oil-free devices with two rotors that revolve counterclockwise. Compressed air returns into the housing from the pressure side once the compression chamber comes into contact with the outlet port. As the compression chamber's capacity continues to drop with steady rotation, more compression occurs. This indicates that full counter-pressure is applied during compression, which harms efficiency and raises noise levels.

These blowers can only be used in situations requiring single-stage compression and very low pressure due to their limited efficiency. These are also widely employed as pneumatic conveyance devices and vacuum pumps.

Why is Roots Air Blowers Used?

To produce consistent airflows that are unaffected by discharge pressure conditions, root blowers are used. Root blowers can be used to provide small to high airflow rates and are only applicable to low and medium pressure and vacuum processes.

When a greater volume of airflow at a higher pressure is required, companies use GT-65 Roots Air Blowers. Use these extremely effective blowers to aerate your bio floc plant, effluent treatment plant, or sewage treatment plant to get the greatest performance.

  • Specially constructed lobes for locations where noise levels must be maintained to a minimum (hospitals, hotels, etc)
  • Much quieter: This innovative design can successfully lower noise by about 5 dB.
  • rigid control of quality standards.
  • technological adaptation (size, pressure, design, pump accessories)
  • Modern CNC assembly equipment allowed for the accurate measurements and grinding required for more effective pumping.
  • For shafts, gears, and bearings that last longer, the lobe transmits fewer vibrations.
  • Any backflow pressure toward the rotor is controlled by the three-lobe arrangement.
  • outlet without any oil or dust.
  • High-quality oil, which is a considerably superior lubricant to grease, is used.
  • Wider air, pressure, and vacuum range, more steady flow, and fewer pressure changes are only a few of the significant improvements in air performance ratios.
  • lessen the energy used.

Includes all of the following accessories: Flexible joint Check Valve, Short pipe, Motor Pulley & V-Belts, Belt Guard, Safety Valve, Pressure Gauge, and Base Common. Considering the aforementioned advantages, a GT-65 roots air blower is worth investing money in.

Importance of Roots Air Blowers

In operations for surface treatment like galvanizing and chrome plating, root blowers provide air and pool mixing. Blowers' oil-free air is crucial for maintaining the surface treatment liquid's cleanliness.

In thermal forming processes, a Roots blower removes the air by vacuum, and atmospheric pressure forces the plastic to press firmly against the pattern. The created piece is taken out and trimmed after cooling.

Sheet materials are held on vacuum tables for mechanical processing. Vacuum pumps are used by router machines to stop the movement of sheet material while it is being cut. For these applications, vacuum air is supplied using Roots blower pumps.

For aquaculture applications and fish farms (for fish aeration), roots-type blower pumps continuously deliver fresh air. Air must be pumped into fish ponds and tanks to provide the fish within with oxygen. Aquaculture applications need continuous air supplied by positive displacement blowers.


One of the safest methods of product preservation is air drying. Roots blowers can produce humid air with precise temperature and pressure control. Most of these materials' characteristics are preserved as a result. As a result, it may be preserved quickly, safely, and affordably.

Roots blowers play a crucial role in providing the pneumatic conveying system with oil-free, pristine pressured or vacuum air. However, it's crucial to pick root blowers that will deliver materials equally and effectively control how they're processed as they move through the system. So, always do your research well before purchasing a roots air blower. Contact Green Dot Limited for any queries regarding roots air blowers and their application!
