Reliable Roots Blower Manufacturer - Vacculex

Roots blower is a positive displacement blower, conveying air volume proportional to the rotational speed. The three-blade impeller is driven by two impellers to complete the suction and discharge three times per rotation. The two impellers are driven by synchronous gears to maintain the correct phase at all times.

RB series blowers are premium heavy-duty blowers with complete models and long history of production, pitches from 3.25″ to 12″ and rotor lengths from 2.5″ to 48″. This series of blowers has a reputation for high quality,high reliability and outstanding performance. Single unit pressure can reach 18PSI(g) and vacuum grade can reach 16″Hg(a).

RB series blowers adopt high speed and high efficiency blowers. Under the premise of ensuring reliability, the higher rotation speed, the lower return flow of the gas in the rotor through the rotor gap which improve the compression efficiency, the lower shaft power, the higher efficiency, Vacculex blowers save energy up to 5-10% on average than domestic blowers. Due to the high rotation speed, more fresh air is inhaled, less hot air is returned, and the gas exhaust temperature is greatly reduced, extending the life of shaft, rotor, bearing and seal.

If you’re looking for an efficient way to create airflow, a root blower may be the perfect solution. These devices are used to generate constant airflows that are independent of discharge pressure conditions. This means that they can be used in low and medium pressure and vacuum applications, making them well-suited for a variety of purposes.

Some common applications for root blowers include manufacturing processes such as stamping and die casting, printing, coating/lamping, gas cleaning/purging, food processing (drying), pharmaceuticals (vacuum evaporation) and more.

Depending on the models available, root blowers can produce airflow rates from 0.5 CFM up to 10 CFM per minute. So whether you need a small amount of airflow or you want something with greater power capabilities, a root blower may be just what you’re looking for!

The two rotors on a roots blower contain two or three meshing lobes inside an airtight case. The case is valve less and has inlet and outlet ports that are generally on opposite sides. The rotors counter-rotate and are synchronised using a set of gear wheels. This configuration creates powerful suction that pulls dirt, dust,and other objects towards the outlets where they can be easily disposed。

Roots blowers are a very common type of ventilation equipment, used to distribute air throughout a building. They operate by displacing air from the inlet to the outlet through counter-rotating rotors. This motion creates a flow of air that is determined primarily by the rotational speed of the rotors within the roots blower. There is no change to air volume within the roots blower, so there is no compression taking place. Roots blowers are generally air-cooled, and some models operate without any need for oil as a lubricant (oil-free).

Today, there are a number of compressor types on the market. However, when it comes to which one is best for a given application, there can be no doubt about the superiority of root blowers. These machines have many advantages that make them superior to other compressors:

– They have only two moving parts (i.e two rotors) which are identical in shape and size. This makes them more reliable and easier to operate.

– Their operation is entirely rotary. This eliminates the need for gears or shafts, making them faster and more efficient than other types of compressors.

– As the rotors are symmetric about their center of rotation, the operation is dynamical balanced – meaning that everything functions as planned regardless of how much pressure is being exerted on any one part of the machine.

– Discharge of the compressed gas is complete and there is no clearance volume – another advantage over other types of compressors

The “Roots,” lobe-style blower is a type of positive displacement (PD) blower, the latter of which was invented in the late s by the Roots brothers. Positive displacement blowers operate with flow and pressure as independent variables; this means that if pressure increases and speed remains constant, the flow rate is largely unaffected. Keeping this in mind, PD blowers are ideal for applications that require variable flow and pressure. This particular type of PD blower is often used in industrial applications because it offers high discharge rates while maintaining low noise levels.

Blower technology has seen a number of advancements over the past few years, but noise reduction has been the primary focus. The Roots blower, which was first developed in , uses two bi-lobes to produce high amplitude waves at a low frequency. This innovation decreased efficiency slightly, but it reduced noise levels to below 85 dBA as mandated by OSHA. As more and more businesses become aware of the importance of reducing noise levels, blowers will continue to evolve in order to meet these health and safety standards.

Identify the amount of volume flow and pressure head

Does your system require a higher volume, flow and pressure but reduced power consumption? Do you need help knowing the amount of volume flow and pressure your system needs for it to efficiently convey materials into production line?

Vacculex can help calculate this for you. Tell us the material you need to transport into your systems and we will handle it from there. Contact us online for assistance. Otherwise, see the pressure ratings of our roots blowers to properly assess if it fits your requirement.

Performance ratings

The performance rating of roots blowers are influenced by the following factors:

Speed and motor rating

Gears and systems need to be working together in order to create the most productive outcome. For example, if you’re using a gear that requires a high speed motor, your system may not be able to handle it. Similarly, if your gears are generating lots of noise and vibration, they may not be effective with your other equipment.

Noise

Choosing a roots blower made from materials will help to limit the noise output. These types of blowers use vibration isolators and silencers to reduce the amount of noise that is emitted. Vacculex blowers also come with acoustic enclosures that are designed to fit, which helps to reduce the sound even more.

Heat

The efficient performance of roots blowers is dependent on the correct and effective regulation of temperature within the system. Be mindful of the intensity of heat generated during operation because a slight temperature change can be enough to alter the condition of the material being conveyed into the system.

If you’re using a root blower, make sure that your operating temperatures are in line with its specs. The ideal range for most residential systems is between 50°F and 100°F, but it’s important to check your specific unit’s instructions to ensure accuracy. Too much heat will damage plant materials, while too little heat will result in inefficient blowing and decreased fuel efficiency. Follow these tips to help keep your root sblower running like an engine:

– Install or maintain proper air filters across all parts of your system – this includes not just at the mulch outlet but also at any other places where debris may enter (like vents).dirty air build up can cause malfunctioning equipment by obstructing airflow through critical components

– Check fluid levels regularly and top up as needed to avoid moisture condensation inside machinery and causing engine failures or reduced operability

– Maintain operating conditions in the system by cleaning all dust and debris accumulated on internal system fan blades vents andshaust pipe periodically

Durability

When it comes to Roots Blowers, you want to make sure that the device you choose is durable and will last for years. Here are some factors to consider:

-The material used in the roots blower should be resistant to corrosion and wear.

-The roots blower must comply with standards such as CSA Z240 or EN .

A thorough analysis of your installation and application is key to selecting the right technology, and there will undoubtedly be one or more aspects might take precedence over others. For example, a smaller space for the blower might dictate choosing a technology with a smaller footprint and lower noise levels, while an application that requires lower energy costs may be best suited for an energy-efficient technology that has a higher initial cost. Key factors that should be taken into consideration include:

A correctly sized blower installation will help to achieve a more energy-efficient process. For instance, in a situation where compressor turndown is employed as the low-pressure source, replacing the compressor with an air blower to deliver 0.3 and 1.5 bar(g) air will result in significant savings. For every 1 bar(g) the air is compressed above the actual demand, 7% of energy is wasted.

Site conditions have a bearing on blower choice. For example, dusty environment or hot humid site for a blower installation might dictate the choice of a technology offering a reliable positive displacement screw, lobe blower or multi stage centrifugal to provide a reliable source of low pressure air with no much of sensitivity to dust or high ambient temperatures. On the other hand, the application criterion of lower energy costs may be best met by a more energy-efficient technology that comes with a higher capital cost.

The cheapest solution to purchase does not automatically result in the lowest operating costs. It is therefore advisable not only to consider the investment costs in the design phase, but also to keep an eye on the necessary expenses over the entire life cycle of the machines to get the maximum ROI.

When it comes to routine maintenance and service support, some older blower technologies may require units to be serviced, repaired or re-furbished offsite. Advanced design developments in the latest oil-free, low-pressure blowers now sees the inclusion of low maintenance components, extended on-site service intervals, each blower technology need to have routine services and checkups , however the each technology design and mechanism differs on the number of consumables and service periods  and the benefits of lifetime customer support plans.

It pays to check the vital statistics. As an example, the tri-lobe rotors incorporated into the latest generation of low-noise, low-vibration, low-pulsation blowers are capable of sweeping nearly six times the volume of air in a single revolution compared to their belt-driven, twin-lobe predecessors. On average, this older technology experiences 5% - 7% more transmission losses.  

An important advantage of the direct-drive, oil-free, rotary screw blowers is wide turndown, especially on models with integrated inverter drives. This allows the units to match the airflows to the daily and seasonal variations in the effluent inflow, resulting in additional energy savings. In order to cope with fluctuations in air demand, screw blower technology can operate from 100% capacity to 25% with very little change in specific power requirement.

There are multiple compression technologies that are used for generating low pressure air. The three main technologies that are popular today are lobe, screw and centrifugal; and within the centrifugal technology there is multistage, high speed turbo or integrally geared centrifugal blowers. So, this takes us to five types of blower technologies that are used extensively within the low pressure market.

Each technology has its own space like lobe typically is the best when it comes to pressure below 0.3 barg and flow less than 500 m3/hr, while screw works better at higher pressure and flow between 500-5,000 m3/hr and then centrifugal technology takes over for larger volumes.

However, the decision on a compression technology is steered by energy efficiency which is also linked to the specific application of low pressure air.

Atlas Copco is one of the very few global manufacturer that has expertise in all the technologies and could offer the most suitable and reliable system that can deliver the best energy efficiency of a low pressure compressed air installation by combining different compression technologies available to handle the compressed air demand.
