DN #10 w/motor AIR 180 M6 18.5 kW 1000 rpm, execution 3,2

Smoke exhauster of the DN #10 series with Electric motor AIR 180 M6 18.5 Power kW 1000 Vol./Min electric motor, manufactured from high-quality carbon steel.

DN #10 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.

Additionally, an oil bath is installed to provide effective cooling and continuous lubrication of the bearings, significantly extending their service life.

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 #10 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 #10 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 180 M6 18.5 Power kW 1000 Vol./Min, specially selected for DN #10

The DN #10 w/motor AIR 180 M6 18.5 kW 1000 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 #10 w/motor AIR 180 M6 18.5 kW 1000 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)
