consist of a fan rotor or wheel within a scroll type of housing and includes driving mechanism supports either for belt drive or direct connection
Centrifugal Fan
also referred to as a cross-flow ventilator or tangential fan
Cross-Flow Fan
is a machine responsible for moving either gas or air for various application using rotary lobes or reciprocating piston
Positive Displacement Blower
is a device that moves air through the use of centrifugal force generated by rotating impeller
Centrifugal Blower
are rotating machines able to
increase the pressure of air or gasses, by means of the centrifugal force normally transmitted by an electric motor.
Multi-Stage Centrifugal Blower
follow the compression principle of the centrifugal compressor or dynamic compressor with a radial design. It works at constant pressure with performance depending on external
ambient conditions delivering compressed air without pulsations.
High Speed Blower
also called a side channel blower or ring
compressor, pulls air or gas into a side channel through the air inlet.
This air is progressively accelerated and pressurized by one or more impellers rotating inside the impeller chamber.
Regenerative Blower
is a compression system that traps air in a fixed space, then applies external force to compress the volume to acquire pressure.
Positive Displacement Type
is a compression system that accelerates air flow and converts the flow rate into pressure
Dynamic or Turbo Type
is the oldest and most common type of industrial compressor. This type of air compressor uses principles of displacement to increase the pressure of the enclosed volume of gas or air. They are available in a range of configurations, from singleacting, double-acting, oillubricated or oil-free.
Piston Compressor
The air is taken into the annular chamber centrally and the air accelerates under the centrifugal force because of the rotational motion inside the circular center.
Centrifugal Compressors
In the operating system of axial flow compressors, the air puts into operation parallel to the rotational axis and proceeds helically.
Axial Flow Compressor
consists of multiple rows of rotating blades attached to a shaft. The rotating blades add kinetic energy to the gas by accelerating it, increasing the velocity of the gas.
Rotor
After the gas exits to the rotor, it passes through the stator, which consists of stationary blades. The stator’s function is to convert the increased velocity of the gas into pressure by slowing down the gas.
Stator
The casing surrounds the blades and helps direct the flow of air through the stages. It also prevents the compressed air from leaking out.
Casing
Axial compressors typically have multiple stages, which work in sequence to compress the gas progressively.
Stages
The air is converted into small successive volumes by the
external central pumps. As the volume decreases, it is ensured that the pressure increases. The rotating part of the engine draws the fluid from its inlet, rotates the fluid circularly around it and transfers it to the high-pressure part at its outlet.
Rotary Positive Displacement Compressors
These compressors use two interlocking helical rotors (screws) to compress gas. The gas enters the chamber, gets trapped between the screws, and as the screws turn, the space between them decreases, compressing the gas.
Rotary Screw Compressor
These compressors have a rotor with vanes that slide in and out. As the rotor turns, the vanes trap gas between the casing and the rotor, compressing it as the space reduces.
Rotary Vane Compressor
These compressors use two interleaved spiral-shaped scrolls. One remains stationary while the other orbits around it, trapping and compressing gas in the pockets between the scrolls.
Scroll Compressor
These compressors have two rotating lobes that trap gas between them. As they rotate, the gas is compressed and forced out.
Lobe Compressor
are compressors that use falling water or water under pressure by applying pressure to air, without using any industrial moving parts.
Hydraulic Compressor
have orifices from which the compressed air or vapor come out. High pressure air expands while it comes out of this orifice and
takes the air with it thanks to its rapid movement.
