The power of mobile smoke exhauster is a weapon for firefighters to fight and control building fires. The unique blade design can quickly generate a strong airflow, creating conditions for positive pressure air supply. Rapid and effective smoke exhaust and air supply technology is the guarantee to ensure the safety of firefighters and people trapped in fire. Shuntong series smoke exhausters send outdoor air into buildings, and the air pressure in buildings will increase, forming a pressure difference with the outside air. Under the action of such pressure difference, indoor positive pressure air will quickly flow to the outside, thus achieving the purpose of smoke exhaust and air supply.

Working principle

Gasoline combustion and work: Gasoline is mixed with air and ignited in the engine cylinder, pushing the piston to move back and forth, which is converted into rotational power of the crankshaft, providing the core driving force for the smoke extractor.

High.speed rotation of impeller: The engine power is transmitted to the fan impeller, causing the impeller to rotate at high speed, generating negative pressure (on the intake side) and positive pressure (on the exhaust side), thus creating an air pressure difference.

Directional smoke delivery: The negative pressure side draws in smoke from the site, while the positive pressure side expels the smoke through the exhaust outlet (which can be connected to a smoke exhaust duct). At the same time, fresh air is introduced, quickly improving the ventilation environment in enclosed or semi-enclosed spaces.

Structure Features

Generally composed of blades, a steel air ring, a four-stroke gasoline air-cooled engine, a protective mesh, mobile wheels, a folding handle, an angle-adjustable foot pedal, etc. The air outlet of the air ring can be designed with a blockage feature to facilitate the use of smoke exhaust ducts.

Product Advantages

• High mobility: Equipped with mobile wheels and a folding handle, the unit has a compact size, making it easy to move and store in complex environments. Some models also feature off-road tires, enabling them to adapt to various terrains.

• Strong power: The gasoline engine provides powerful performance, delivering a large smoke exhaust volume, quickly removing smoke, and effectively improving on-site air quality.

• Wide application range: It has good low-temperature starting performance and can operate normally in harsh environments.

The above is just one model. There is another one with slightly different specifications. Let’s take a look.

Performance parameters

• Large-capacity turbofan, suitable for warehouses, commercial buildings and large buildings, provides higher smoke exhaust.

• Four-stroke engine reduces noise and vibration and increases safety.

• Synthetic resin blades have high dynamic balance precision, which can greatly reduce the chance of machine stress and damage.

• Fast and convenient pedal positioning device can adjust the air outlet angle of the air duct.

• Telescopic handle, convenient for push-pull operation

• Surrounding the metal protective frame, no matter where it falls, it will not damage the smoke exhaust machine.

• Inflatable casters suitable for rugged terrain, easy to move.

• Safety nets are installed at the air inlet and air outlet of the fume exhauster, and the clearance of the net cover is ≤8mm, which meets the national safety standards.

• Running stability: continuous running for 120min at minimum elevation angle, and self-moving distance ≤ 200 mm.

• The exposed parts of the exhaust pipe and muffler have heat insulation protection measures.
