Swingfog: High performance fog generators

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive


At the end of the 1940’s, the first Swingfog thermal fogging machine was developed and built.

Originally, the engine principle served for the propulsion of rockets. Further development of this technology resulted in the so-called Swingfire process. The idea has been successful in the market for more than 60 years, and the Swingfog brand name has become synonymous worldwide for thermal fog technology. Our present manufacturing programme is the result of our competence and experience, continuous development, as well as the permanent improvement of our products.






Today, Swingfog means: Engineering at a high level combined with a complete utilization of know-how. In other words: Technology and application under one roof.




Swingfog fogging technology is the efficient and economic method for:

  • mosquito and pest control
  • plant protection in plantations and greenhouses
  • stock protection in warehouses, silos and plants for processing foodstuffs, agricultural products, textiles and tobacco
  • disinfection in the foodstuff industry, in areas occupied by people and in the livestock industry



Swingfog SN 50

Portable machines, available with four types of chemical tank made of stainless steel or synthetic material (polyethylene). The fuel tank is made of stainless steel. All metal parts coming into contact with the chemical are also made from stainless steel.

Swingfog SN 81 / SN 81 Pump

Stationary machines, available with two types of chemical tank made of stainless steel or polyethylene. Fuel tank made of stainless steel.
The Swingfog SN 81 Pump is equipped with an electric stainless steel feeding pump to draw the fogging mixture from a separate tank. The SN 81 Pump is supplied with a rechargeable battery to drive the chemical pump and a battery charger.


Swingfog SN 101

Vehicle mountable large fogging machines. Available with manually operated starting pump (SN 101 M) or with an electrical starter (SN 101 E and SN 101 Pump).
Both, the SN 101 M and SN 101 E types are equipped with stainless steel chemical tanks that have a capacity of 69 l.
The SN 101 E is supplied with a rechargeable starter battery and a battery charger.
The SN 101 Pump has no chemical tank, but a large fuel tank with a capacity of 21.3 l, which allows for a continuous operation of approximately 5 hours. The fogging mixture is drawn, by means of an electrically driven stainless steel feeding pump, from a separate tank.


Power to start the SN 101 Pump and to drive the chemical pump is drawn via a cable connection to a 12 V vehicle battery.
All Swingfog SN 101 models are supplied with an automatic cut-off device for the fogging mixture and can be equipped with a remote control (optional accessory). Fuel tanks are made of stainless steel.




Swingfog fogging machines run with regular grade gasoline (petrol) in accordance with the Swingfire principle. A fuel/air mixture is ignited in the combustion chamber and the deflagrations oscillate a column of gas in the resonator pipe between 80 and 110 times per second (depending on the type of machine). At the end of the resonator, the fogging mixture is injected into the air stream emerging at high velocity, and is dispersed into fine aerosol droplets, which are distributed into an extensive, dense fog. Fuel and fogging mixture are conveyed by a small positive pressure in the tanks. For the SN 81 Pump and SN 101 Pump types, the fogging mixture is drawn by an electrically driven stainless steel pump. The system has, with the exception of diaphragms, no moving parts and, therefore, practically no wear.


Power supply – power consumption

Electrical energy is only required to start the machines, it is not required for ignition during operation. The battery capacity is selected to match the power consumption of the magnetic valve of the automatic cut-off device and the fog on/off functions of Swingfog SN 81 Pump and all SN 101 types, as well as for the operation of the electrically driven feeding pump for the fogging mixture of Swingfog SN 81 Pump and SN 101 Pump.

Droplet distribution

Our advantage: Using water-based fogging mixtures, together with the high performance fogging tube, an excellent droplet spectrum is achieved, which is usually only possible with oil-based mixtures.


Standard fogging tube for oil-based fogging mixtures



High performance fogging tube for water-based fogging mixtures (optional accessory). Using this device for the application of water-based fogging mixtures, an excellent droplet spectrum is generated, which is almost identical to that of oil-based mixtures. The high performance fogging tube must only be used for water-based fogging mixtures.






Electrically driven feeding pump, made of stainless steel for Swingfog SN 81 Pump and SN 101 Pump. The pump can be applied as a submerged pump or can be connected to a quick-release coupling to draw the fogging mixture out of a separate container. Power supply is provided by connection of the Swinfgog SN 101 Pump to a 12 Volt vehicle battery. The Swingfog SN 81 Pump is supplied with a rechargeable 12 V / 12 Ah battery and a battery charger. The pump can be driven by the battery or by the public power supply by connecting the battery charger to the power source and the battery.

Special type SWINGFOG SN 50A
Using this special fog applicator, it is possible to direct the fog into the smallest of apertures in buildings or sewage systems, or to combat leaf-cutting ants in subterranean ant nests. The fog outlet is put directly into one of the ant nest entrances and the complete nest is saturated with fog. All models of SN 50 are available in a special “A” version and with automatic cut-off device for the fogging mixture.

Remote controls for the Swingfog SN 101 M, SN 101 E and SN 101 Pump. All operational functions can be controlled via the remote control from the cabin of the vehicle or directly at the control panel of the machines (optional accessories).
