 2. Characteristics 

      ♦ Can output higher discharge pressure, and working at high medium temperature condition, applicable to any industry condition which need to conveying high pressure & high temperature gas.

♦ 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.

♦ In the case of using system base, so easy for installation, no need of professionals direction.

♦ Transmission efficiency higher than belt driving’s, much lower of fan system energy loss.

♦ Flexible connection for motor shaft and transmission shaft, no need to tension or change the belt, low maintenance work.

♦ Cooling method of bearing, choosing low cost water cooling method or good heat dispersion oil cooling method according to gas temperature and running condition. Or installing BOX COOL for very high temperature medium condition to protect fan system operation reliable completely.

♦ 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.

♦ Can satisfy different dust loading conditions that low dust loading to a good deal dust loading, the surface hardness of impeller can reach to HRC60~70 after special processing, greatly extending impeller’s service life.

♦ 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 reserves installation place for temperature and vibration sensors, can install easily of fan running monitoring device.

♦ 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.

♦ Selecting high efficiency energy saving motor of Chinese leading motor manufacturer( or customer required), reliable quality, low energy consumption.

♦ The motor load can be automatically reduced when airflow resistance is increasing, to prevent 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 reducing 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 impeller and main shaft passed ultrasonic flaw detection, ensuring no defect of welding and materials, guarantee 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.
