Forced Draft Industrial Centrifugal Fans Small Centrifugal Blower Fans High Pressure

Forced Draft Industrial Centrifugal Fans Small High Quality High Pressure

The Model 9-19 and 9-26 high-pressure centrifugal fan is extensively applied to transmit materials. The transmission medium is air or other non-flammable gases, which are harmless to human. The medium does not contain any adhesive materials. The gas temperature is ≤80℃,and the dust and particle volume are ≤150mg/m3. It is generally suitable for enforced high pressure ventilation in such
industries as forging and smelting, glass, pottery, electroplating, battery and wireless sectors, etc. It is also used to deliver grain, fodder, ore powder, plastics, etc. in the processing industries. It is also suitable for the combined use with carton machinery and tempered glass equipment.

Centrifugal Fan
Because of the high pressure they create, centrifugal fans are ideal for high pressure applications such as drying and air conditioning systems. As all of their moving parts are enclosed and they also have particulate reduction properties that makes them ideal for use in air pollution and filtration systems. Centrifugal fans also offer distinct benefits:
First-rate energy efficiency.
Constant airflow allows centrifugal fans to generate energy that reaches up to 84% static efficiency. These higher efficiency levels are ideal for sustaining larger air systems.
Enhanced durability.
These fans are durable enough to properly operate in the most corrosive and erosive environments.

Easy to maintain.
Lighter material fans can be easily cleaned when you deem it necessary. Moreover, certain fans have self-cleaning characteristics, making daily maintenance that much easier.
High versatility.
Centrifugal fans are useful for multiple airflow/pressure combinations, and they can process several airflow conditions, including clean, dry, and wet air.

Impeller passed high standard dynamic balancing, ensuring stable running of fan.
Running test and vibration value test for fans after finishing manufacturing, ensuring running reliably.
Impeller of annealing treatment, completely eliminating structure of internal stress when welding, ensuring impeller appearance won’t occur creepage and flaw.
The welding line of impeller and main shaft passed ultrasonic flaw detection, ensuring no defect of welding and materials, guarantee strength.
Can flexibly adjust fan’s volume and pressure in running by air damper. Can also adjust fan’s pressure and volume by changing the fan speed via matching variable frequency motor.
Regarding to material of impeller and main shaft, we will choose high strength carbon steel, low alloyed steel, High temperature resistant alloy steel, High temperature resistant high strength alloy steel according to different medium temperature and running speed, ensuring the impeller and main shaft keeping reliable strength in high temperature.
Using liquid lubricating oil, no need to open bearing housing when changing or filling lubricating oil.Easy to observe the lubricating oil’s quality and stock through inspection window on the bearing housing body.
Bearing housing adopt labyrinth type mechanical seal, unique design of spill prevention of inner, venthole design on top, commissure coated with sealing grease, completely eliminating bearing housing oil leak.
