7.5kw belt-free turbine blower is a non-positive displacement, high volume, high pressure, blower that can operate as either a compressor or a vaccum pump. It is also knows as other names such as regenerative blower, vortex blower and side channel blower. All of the names describe the basic principle of operation of the turbine blower. The blower consist of a strong impeller mounted directly on a motor shaft and is rotated at very high speed of about 2900 R.P.M. On the periphery of the impeller is large number of radial blades. The impeller is positioned between two end plates and with the blades located with a channel on either side.

High speed centrifugal blower, as the name suggests, high speed, fast. It is also called high speed turbo blower. Under the design conditions, the air pressure of the high speed centrifugal blower reaches 50-290 mbar, the air volume is 85-6000 cubic meters per hour, the rotating speed is 18000-21000 rpm, and the air volume is three times that of the ordinary high-pressure blower. Therefore, it is also named high-speed blower, and the use effect is more than 95%. High speed centrifugal blower is also called: High-speed fan, High-speed blower, turbine type high-speed blower, super fan, high-speed centrifugal fan, etc., but it is generally called high-speed centrifugal fan in foreign countries, because the fan uses the centrifugal principle to generate rotating mechanical energy and convert it into aerodynamic force with a certain pressure. The English name is mostly centrifugal blower.

Side channel blowers are of use to any process that requires a high volume low pressure delivery system for air or gasses. Here is a list of common use cases including air knives, dry tunnel blowing, process cooling, air cushions, packaging processes, vacuum cutting tables, vacuum cleaners, vacuum cleaning systems, industrial fume/heat extraction, aeration, blowers for swimming pools.

Air knives, including strip air knives and ring air knives, are a kind of equipment specially designed to blow out strong and high-speed airflow to remove dust, blow water stains, and cool down. There is also an air knife for cutting boards. The air knife consists of high-intensity, uniform laminar airflow.

Stainless steel adjustable air knives have the greatest advantage which is that going through an adjustable outlet the airflow can be more stable and stronger. Stainless steel air knives are featured by high precision, strong hardness, high pressure-resistance, and great temperature-resistance. The air knives are widely used in all kinds of blowing off system and air knives drying system. They are also widely applied for ultrasonic cleaning, glass cleaning machines, and dehydration and drying of a circuit board, electroplate, film, coating, non-ferrous metal board/wire/sheet, and other related materials and industries. Moreover, they are also utilized in the barrierless isolation of harmful gases, dust, hot and cold air, drying after printing, heating, and thawing of food and medicine, and high-temperature sterilization.

The greatest advantage of spider nozzle air knives is that they can flex to any position around the bottle to accommodate specific drying needs. Spider air knife has been through many tests and trials. Its innovative design, not only improves the drying efficiency of the bottling and canning production line, but also reduces energy usage by as much as 80% compared with traditional air knives. Moreover, spider air knives also solve the following problems that occurred on the traditional bottling and canning production lines–two air knives usually head to head blow air, which offsets the airflow and even makes a “drying blind” zone.

belt-free centrifugal blower is an air moving device that uses an impeller to pull air into a tube like structure and release it at a 90o angle. The impeller is a set of blades inside the blower that rotates at a high rate to pressurize and move air. The structure of a centrifugal blower does not require housing for protection, but those with housing are the most common.

The double-stage single phase side channel blower are conceived to suck or to compress gas and non-explosive mixtures. The absence of lubricants guarantees that no oils are present in the compressed fluids. The blowers are equipped with single-phase motors and IE3 high efficiency three-phase motors. The main advantages of double-stage blowers are no maintenance, no contamination of conveyed fluids, silent operation, small size and weight, easy of installation, stability and absence of vibrations. The blowers are mainly applied in fields including air and gas conveyance on machines and plants requiring high suction and delivery pressures, max. operational safety and low noise levels.

Bare shaft side channel blowers are very widely used, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans, air conditioner outdoor fans are axial flow fans. The blowers are usually used in applications with high flow requirements and low pressure requirements. The blower fixes the position and move the air. The bare shaft side channel blowers are mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.

There are many blower accessories including press relief valve oil sight gauge, blower lube, bearings and seals, blower bolt kit and alum blower studs.

What are air compressors? Technically, air compressors are machines that convert one form of energy into another form, which can then be stored and used at a later point in time. But neither that brief explanation, nor the more detailed description below do this invention and its profound impact on our lives.


That is why it is "The machines that have changed our world more than almost any other invention.”


What may sound like hyperbole is actually a very accurate description of the impact air compressors have had on our society – and especially the industrial sector. In less than 150 years since Austrian engineer Viktor Popp built the first compressor plant, compressed air has become so indispensable that it is now referred to as the “fourth utility” along with electricity, water and gas.The numbers back up this bold statement. It is estimated that 10% of all electricity consumed by the manufacturing industry is used for compressed air.


To understand the importance of compressed air and the compressors that generate it, let's first take a closer look at the physics of it. Compressed air is simply regular air that is forced into a much smaller space. When this happens, its molecules speed up and so-called "kinetic energy" is created. That kinetic energy can either be used right away or it can be stored and released later.


One of the reasons compressed air has become so indispensable is its versatility. Just about every industry relies on compressed air in some form – from manufacturing plants to cars, ships and trains, construction sites to hospitals, compressed air is used all around it.


With so many different Compressor Applications such as Oxygen and Nitrogen Generator, it also makes sense that there are many different types of air compressors. After all, the small and quiet compressor that powers a dentist’s drill should not be the same as the industrial compressor that keeps an entire manufacturing plant going.


However, the many options also make it difficult for laypersons to find the compressor that is right for them. To make things easier, here is an overview of different compressor types and technologies.


First, let’s take a look at how compressors work. There are two main compression technologies. Positive displacement compressors have a cavity that is filled with regular air (or another gas at atmospheric pressure). That cavity then becomes smaller, which means the same amount of air has to fit into a smaller space and its pressure and kinetic energy increases. Dynamic compressors achieve the required rise in pressure by accelerating the air (or gas) with an impeller and then slowing it down in a diffuser.


Positive displacement compressors are much more frequently-used and they feature different technologies to displace the air. Piston compressors use a reciprocating motion, rotary screw compressors a single rotor and the more seldomly utilized scroll compressors feature a double rotor.


Each of them has their different benefits and uses. Piston compressors, for example, are fairly simple machines that are inexpensive to buy. They are often the right solution for operations with a low compressed air demand. Rotary screw compressors are more advanced and offer a low total cost of ownership. They are more energy efficient and can produce a lot more compressed air. Dynamic compressors, on the other hand, are primarily used for operations and applications that require very high volumes of air.


There are also some Compressor Accessories like Air Compressor Air End required for the normal running of the machine.
