DECENT MACHINERY offers a full range of multistage centrifugal blowers with 20 models to choose from. We have the right blower for your application today and our Research and Development department is developing new models to meet your needs tomorrow.

Product performance ranges up to 98Kpa pressure or to -40Kpa vacuum and flows from 35 to 220 m³/min. Dacheng manufactures blower and process control systems as well as provides complete blower packages with accessories to meet a wide variety of applications.

Series DM casting multistage centrifugal blower is a highly efficient blower product which is developed by our company to introduce American technology and has advanced levels in the world today.
This series of products adopts many proprietary or patented technologies, and the blower has much better performance than other competitors in lower noise levels, lower vibration, and higher efficiency.

Many models feature our patented Multiple Baffle Rings which help turn airflow smoothly into the eye of the impeller, dramatically reducing inlet passage losses. MBR combined with the two-dimensional impeller design increases blower efficiency and pressure/vacuum capability.

Application:
1. Water Treatment
2. Wastewater Treatment   
3. Biogas  Recovery
4. Vacuum Cleaning
5. Air Knife Dry
6. Floatation and Mineral Beneficiation
7. Galvanization Process and Electric Plating
8. Fluid and Piscina Oxygenation
9. Process  Gas Conveying
10. Papermaking and Printing
11. Air  Firing (Desulfurization, Carbon Black, Blast Furnace Process, and so on

The centrifugal blower housing consists of an inlet head with a special feature to direct air to the inlet of the first impeller and outlet head of special design to eliminate friction and multiple intermediate sections.

These parts are made in cast aluminum according to rigid Continental Industrie specifications, extreme care is to be exercised in the assembly of interlocking cast aluminum intermediate sections and annular diffusers (baffles). The entire assembly is securely held together actually with multiple tension rods which bind the entire housing into a solid integral unit. 

There are no parts in relative creep during operation. Since there is no friction and therefore no lubrication is necessary, the conveyed air is not polluted. Moreover, the main advantages of using Decent Machinery multistage centrifugal blowers are:
 1.Easy Installation;
 2.Low Noise Level;
 3.No Vibration;
 4.Pulsation Free Gas Flow;
 5.No Gas Contamination;
 6.Minimal Maintenance.
