Product Description
Forward-curved Centrifugal Boiler Fan Blower is also commonly known as Centrifugal Fans in industry. In a blower, the inlet pressure is low and is higher at the outlet. Centrifugal fans consist of an impeller in a casing having a spirally shaped contour. The air enters the impeller in an axial direction and is discharged at the impeller's outer periphery. The blower is also commonly known as Centrifugal Fans in industry. In a blower, the inlet pressure is low and is higher at the outlet.
We supply HIGH -PRESSURE BLOWERS for various industrial applications.

Characteristics of Single Inlet Industrial Boiler Centrifugal Exhaust Fan 2500 cfm
♦ Outputting higher gas pressure, and providing larger air flow volume, low noise.
♦ Blades angle going through optimizing design, higher wear resistance, longer service life.
♦ Can flexibly adjust fan's volume and pressure in running by air damper. Can also adjust the fan's pressure and volume by changing the fan speed via a matching variable frequency motor.
♦ In the case of using a system base, so easy to installation, no need for professional direction.
♦ Transmission efficiency higher than belt driving's, much lower fan system energy loss.
♦ Flexible connection for motor shaft and transmission shaft, no need to tension or change the belt, low maintenance work exhaust fan.
♦ Fan system whose impeller's diameter is below 1400mm, is not needed to match the bearing cooling device, can reduce the customer's cost and maintenance work.
♦ Can satisfy different dust loading conditions that low dust loading to a good deal dust loading, the surface hardness of impeller can reach HRC60~70 after special processing, greatly extending the impeller's service life.
♦ Using liquid lubricating oil, no need to open the bearing housing when changing or filling lubricating oil. Easy to observe the lubricating oil's quality and stock through the inspection window on the bearing housing body of the exhaust fan
♦ Bearing housing reserves installation place for temperature and vibration sensors, can install easily of fan running monitoring device.
♦ Bearing housing adopts labyrinth type mechanical seal, unique design of spill prevention of inner, vent hole design on top, commis-sure coated with sealing grease, eliminating bearing housing oil leak.
♦ Selecting a highly efficient energy-saving motor from Chinese leading motor manufacturer( or customer required), reliable quality, and low energy consumption.
♦ The motor load can be automatically reduced when airflow resistance is increasing, to prevent the motor from destroying.
♦ Customizing design according to customer's performance requirements, and optimizing by CFD technology, energy consumption lower than same fans.
♦ Adopting high-quality carbon steel manufacturing, or stainless steel and other metal materials according to customers' requirements.
♦ Fitting tightly of parts, good sealing, ensuring no reduction of output pressure.
♦ 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 the impeller and main shaft passed ultrasonic flaw detection, ensuring no defect of welding and materials, guaranteeing strength.
♦ 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.
♦ Various optional components for your selection.
