GENERAL INFORMATION ON SMOKE EXHAUSTERS
- Two-way suction;
- Rotating scroll case;
- Д – blades bent forward, ДН - blades bent backward;
- Quantity of blades: Д – 32, ДН – 16;
- Rotation direction – right and left. It is defined from the motor's side according to p. 7.
VARIANTS OF SMOKE EXHAUSTERS PRODUCTION
Smoke exhausters are made of carbon steel.
PURPOSES OF SMOKE EXHAUSTERS
- Smoke exhausters Д/ДНx2 are intended for smoke gases removal from boiler units' furnaces equipped with effectively operating systems of ash catching, as well as for smoke gases removal from gas-fuel boiler units' furnaces.
- Smoke exhausters are designed for long-term mode of operation in a room and in the open air in conditions of a moderate climate.
- Maximum temperature of smoke gases at a smoke exhauster's input is not more than 200°C. The temperature in a scroll is not lower than -30°C.

Smoke exhauster – these devices (exhaust fans) for flue gas evacuation, catching ash and combustion products from heat power plants.
Exhauster Д -used to remove smoke from the premises, in the absence of natural ventilation and installed over:
The flue gas pump ДН is used for the same facilities and conditions as for the smoke exhaustor Д, as well as for operation in the elevated temperature mode and ash collection system. Impeller bearings are protected by a hub.
Exhauster Д two sided suction price
Smoke detectors Д and ДН, in contrast to the ВДН fan, have more thickened cochlear walls.
- The main characteristic of smoke exhausters ДН is a great resource of reliable and continuous operation
- Climatic performance - У, ХЛ, Т (used indoors and outdoors).
- Have left and right rotation.
- Temperature mode: *
- * Impeller (carbon steel) + 200 °C - 250 °C
- ** Impeller (alloy steel) + 400 °C
- *** Lower temperature mode is 30 °C.
- Number of blades: (Д – 32), ДН – 16. The structural modification of the blades allowed to reduce the pressure by 30%, while the cost of electricity was reduced by 17%.
- Dust - up to 2 g/m3.

The work schedule for servicing the smoke exhaustor ДН:
- With each oil change, flush bearings with kerosene;
- Check the condition of the lubricating rings;
- Gate valves must be closed;
- Manually check the rotation of the rotors (rotation without effort);
- Ensure that the clutch is in good working order;
- Check engine rheostat.
