Blowers have huge application in manufacturing industries. There are many types and brands of blowers available in the market. Here we are focusing on positive displacement blowers.


1) What is a positive displacement blower?
Positive displacement blowers are the machine that moves air using compression technology. These machines use positive displacement technology by storing some volume of air under pressure and then discharging it out. This discharged air is directed to a pipe to propel gas or any material to the required place.


2) How does the positive displacement blower work?
The positive displacement blower machine consists of two rotors. These rotors are joined together by a gear. Both these rotors rotate simultaneously in opposite direction to suck in air. The drawn is air confined to an area that is blocked by blower casing and rotor. The further movement of the rotor opens up the passage for the trapped air and the air is discharged under pressure with force. The discharged air is not able to return back into the blower casing due to the small opening. Hence the blower overcomes the line pressure and is called positive displacement blower. Tri-lobe blower consists of a rotor with three lobes and discharges air with more force.


3) What are the types of positive displacement blower?
There are two kinds of positive displacement blower Off-White x Nike Air Max Scontate , twin lobe blower and tri-lobe blower.
Twin lobe blower: Twin lobe blower has 2 straight lobe rotors with two lobes each. It is noisy and vibrates more as compared to a tri-lobe blower.
Tri-lobe blower: It has 2 rotors having 3 lobes each. Tri-lobe rotor discharges air with more force as compared to twin lobe blower. It is led noisy and also vibrates less than twin lobe blower.


4) What are the applications of positive displacement blower?
Positive displacement blowers have huge applications in manufacturing industries. They improve and enhance the manufacturing processes and reduce lead time. It is used in chemical industries for vacuum processing purpose. Dairy industries use this blower for automated milking. Cement and lime industries use positive displacement blower for fluidization of granular cement. It is widely used in plastic industries for the processing of liquid plastic. This blower is also used in power generation industries for conveying fly ash.


5) What are the features of positive displacement blower?
Some of the important features of positive displacement blowers are:
The oil-free mechanism makes it easy for usage and maintenance.
Blowers with extended shaft are more efficient because they don tend to heat much during the operation and discharges air aptly.
Adequately large inlet and outlet ensure optimum efficiency of the blower.


Alloy shafts ensure durability and optimum performance of the blower.
