Roots blower and Roots blower are essentially the same equipment, with different naming conventions, but there may be slight differences in specific application scenarios and industry names. The following is a detailed comparison and explanation:
---
**1. Source of Name and Industry Customs**
-Roots Blower:
-A more formal engineering term that emphasizes its "blowing" function (output pressure generally ≤ 0.1 MPa, belonging to low-pressure fans).
-Commonly used in industrial fields such as environmental protection, sewage treatment, and pneumatic conveying, such as the "Three Leaf Roots Blower".
-Roots blower:
-Abbreviation, colloquial expression, often used in general occasions or non professional documents.
-Some industries (such as small factories) may be directly referred to as "Roots blowers", but their technical parameters are no different from blowers.

**2. Core structure and working principle**
-* * Same * *:
-Both adopt a dual rotor (two or three blade) meshing structure, and transport gas through the principle of volumetric method (without internal compression, pressure is established by system resistance).
-The main components include the casing, synchronous gear, rotor, bearings, seals, etc.
-* * Typical features * *:
-Constant flow rate (proportional to rotational speed), strong pressure adaptability (but limited by structure and material).
-The noise is loud (requires installation of a muffler), and regular maintenance of the gears and bearings is necessary.

**3. Possible subtle differences (non-technical)**
-* * Application Scenario Tendency * *:
-* * Blower * *: More emphasis is placed on the use of "air supply" or "boosting" (such as aeration, backwashing).
-* * Fan * *: may refer to gas transportation in general, but its actual function is the same.
-* * Manufacturer naming conventions * *:
-Some manufacturers label the sample as "Roots blower", while users simplify it as "Roots blower".

**4. Common Misunderstandings Clarification**
-* * Difference from centrifugal fan * *:
-Roots blower is a volumetric type (constant flow rate, variable pressure), while centrifugal blower is a velocity type (constant pressure, variable flow rate).
-* * Difference from air compressor * *:
-The output pressure of the Roots blower is low (usually<0.1 MPa), while the pressure of the air compressor is high (>0.8 MPa), and there is an internal compression process in the air compressor.

**5. Selection suggestions**
Regardless of the name, it is crucial to confirm the following parameters:
1. * * Airflow * * (Nm3/min or m3/h)
2. * * Pressure * * (kPa or bar, such as 49 kPa, 98 kPa)
3. * * Medium * * (air, biogas, corrosive gases, etc.)
4. * * Motor power * * (kW)
For example, the "Roots blower" used in the carbon slurry plant should be labeled as: * * air volume 15 Nm3/min, pressure 58.8 kPa, anti-corrosion type * *.

**Summary**
-Roots blower=Roots blower, with no technical difference in name.
-When selecting, specific parameters should be taken into account, without worrying about the name.
-If mixed in the manufacturer or document, you can directly inquire whether the technical specifications are consistent.
