Product Description

Product Description

 

Greentech International (Zhangqiu) Co., Ltd is the professional roots blower supplier. The NSRH type clover spiral Roots blower on the basis of the manufacture and sale of a Roots blower for many years the development of new products using new technology.
The machine through the use of new lines on the impeller, the overall adiabatic efficiency and volumetric efficiency is further improved, and is excellent particularly in the fan of the air volume and pressure characteristics.
So-called excellent efficiency is the amount of heat generation of the wind turbine itself is reduced, i. E. The temperature rise dropped, the various models using the exhaust pressure in the dry state is up to 1kgf/cm2.
Duty:
Bore: 50 ~ 300mm
Flow capacity: 0.5 ~ 134.1m3/min
Pressure rise: 9.8kPa~98.8kPa
Vacuum: -49kPa

Application:
Mainly used in sewage treatment (aeration), powder conveyor (cement, feed, etc. ), combustion furnace, washing, vacuum packaging.

Features of Series NSRH Tri-Lobe Roots Blower:

1. Each model has a performance table and standard specification, easy to select fan model;

2 Including attachments, fan body to standardize. Mass production system, to be able to meet your requirements at any time;

3. Because there are good helix structure, and using the same fan matching a muffler with a silent air cleaner, the operating noise of the fan is much lower than in the past;

4. Rotor is fully machining precision products. Has been made in the manufacture of the complete dynamic balance, almost no vibration.

5. To take a small design, small mounting area.
