Description

Smoke exhauster of the DN #21 series with Electric motor AIR 355 MV8 200.0 Power kW 600 Vol./Min electric motor, manufactured from high-quality carbon steel.

DN #21 is equipped with a backward-curved blade impeller—a modern engineering solution for industrial smoke exhausters. This design provides high efficiency (up to 80–85%), low noise levels, and stable operation even with changing network resistance. Compared to radial blades, backward-curved blades help reduce energy consumption while maintaining required flow and pressure, and they extend the unit’s service life due to reduced wear.

Advantages of smoke exhausters with backward-curved blades:

  • High efficiency (up to 80–85%), lower energy losses.
  • Reduced power consumption with the same flow and pressure parameters.
  • Quiet and smooth operation, minimal vibration.
  • No tendency to overload: when resistance increases, the smoke exhauster does not overload, and often even reduces power consumption.
  • Extended service life—less wear compared to radial blades.

The smoke exhauster is designed for removal of combustion gases and non-explosive dust-laden air mixtures from furnace chambers of boiler units. It is used for solid-fuel boilers with steam capacities from 2.5 to 25 tons per hour, as well as for gas and oil-fired boilers of similar capacity. The maximum temperature of handled gases is up to +200°C. DN #21 series smoke exhausters can be used both individually and in parallel operation and are equipped with an ash collection system with a cleaning efficiency of at least 90%.

Structurally, the DN #21 smoke exhauster consists of the following units (can be supplied separately):

  • Spiral scroll housing
  • Backward-curved blade impeller
  • Fan base frame
  • Fan collector
  • Electric motor Electric motor AIR 355 MV8 200.0 Power kW 600 Vol./Min, specially selected for DN #21

The DN #21 w/motor AIR 355 MB8 200 kW 750 rpm smoke exhauster housing is welded and made of durable carbon steel. The impeller (cantilever-mounted) is backward-curved, ensuring streamlined gas flow. For long-lasting operation, thickened scroll walls and hardfacing on the blades are used. Standard configuration includes a three-phase AIR electric motor (380V, 50Hz).

The smoke exhauster can be manufactured with right- or left-hand rotation. The scroll housing can be rotated from 0 to 270°.

General specifications of DN #21 w/motor AIR 355 MB8 200 kW 750 rpm smoke exhausters:

  • Single-side suction
  • Spiral scroll housing
  • Backward-curved blade impeller
  • 16 blades
  • Option for right- or left-hand rotation (determined from the motor side)
