It is applicable for exhausting gas containing dust, wooden scraps, fine and crushed fiber etc. (If there are hard particles in gas, a dust-collecting device should be installed in front of the fan). It can also be used as the common ventilation and air-exchange purposes.
1. Air purification and industrial waste gas treatment, Air filtration system, Flue gas desulfurization, Flue gas denitrification.
2. Boiler's air supply and exhaust (Coal-fired boiler, Biomass boiler, Garbage incinerator, CFB boiler, Stokerfeed boiler.).
3. Industrial boiler blowing air, Industrial boiler inducing air, Industrial boiler primary air, Industrial boiler secondary air.
4. Industrial boiler waste gas desulfurization, Industrial boiler flue gas denitrification.
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.
The impeller will do by dynamic balancing tests. It greatly improves the stability of the impeller operation, and reduces the vibration and noise.The Fan with advantages of small volume, light weight, angle adjustable and convenient for installation and maintenance.
