  1. What is the meaning of ESP?

ESP is an abbreviation for electrostatic precipitator.


7. What kind of smoke does your filter treat?

Our ESP filter can treat the oil mist smoke, but we can’t treat the acid, toxic, flammable and explosive smoke.


  1. How does the electrostatic precipitator work?/ What is the working principle of ESP?

filters utilize high voltage electrostatic ionization technology.The exhaust gas is ionized and the grease particles is charged.Thencharged particles are adsorbed on the anode electric field(tubes) and flow to bottom under the action of their own gravity then are discharged through the oil drain. The remaining micron-sized oil mist is decomposed into carbon dioxide and water by the electric field and finally discharge the clean air.


  1. What is the function of electrostatic precipitator?

Collecting and cleaning exhaust gas for commercial and industrial use to help factory owners solve air pollution problem and reach local environmental policies.


  1. What industries use electrostatic precipitators?

For commercial electrostatic smoke filter, it mainly used in restaurant and hotel kitchens cooking smoke and coffee roaster waste gas and CNC machines exhaust.

For industrial ESP filter, it mainly used in textile stenter lines and PVC based products machine lines such as foaming& coating lines and calendaring for PVC synthetic leather, PVC gloves /latex gloves/vinyl gloves,PVC non-slip mat/yoga mat, PVC plastic/vinyl Flooring, PVC wallpaper, PVC tarpaulin, PVC flex banner/PVC lampboxfabric, PVC conveyor belts, PVC plastic wire mesh and PVC cables etc.


  1. Why do we need to keep the air cleaned?/Why we should reduce air pollution?

For the one hand, everyone has a responsibility to protect the environment. Air pollution harms environment and brings ecological disaster.

For the other hand, the restaurants owners and factoriesare obliged to abide by the policies of the local environmental protection department or it would be subjected to complaints from neighbors and fined or even shut downbythe local government department.


  1. How to choose the electrostatic precipitators for the stenter machine?

As we know stenter machine has different models. We will ask the textile factoryto offer the stenter machine parameters so that we can choose a suitable model for it. For example, stenter width and chamber numbers, exhaust temperature, blower numbers, power and capacity etc.


  1. How many days does the electrostatic precipitator need the cleaning?

According to the factory usingsituation, the cleaning time cycle is different.So for the textile dyeing house, it is about one month.


  1. How to do the cleaning for ESP?

After using for some time, the ESP system needs to be cleaned. So we will use the sodium hydroxide as a detergent.


  1. Does the BotonairESP system has auto cleaning ESP?

Yes. We have auto cleaning ESP system, but now only use for textile company.


  1. What is the delivery date?

For Kitchen electrostatic precipitator, if have stock, within 3 days.

For industrial electrostatic precipitator, if standard one, only two weeks. Nonstandard, 20 days.


  1. Is there any fire prevention from the electrostatic precipitator?

For Kitchen electrostatic precipitator, for now no.

For industrial electrostatic precipitator, we have a fire protection system and we use a PLC program to control and the fire will be off within 8 seconds.


  1. How to choose the electrostatic precipitators for foaming oven?

As we know foaming oven has different models. We will ask the PVC factory to offer the foaming oven parameters so that we can choose a suitable model for it. For example, foaming oven length and chamber numbers, exhaust temperature, blower numbers, power and capacity etc.


  1. How many countries that you are successfully sold to?

Our Botonair ESP are sold to more than 20 countries, for example, USA, Canada, Korea, Thailand, Vietnam, Indonesia, Australia, UK, Turkey, UAE, Iran, Russia, Kuwait, Bangladesh, Singapore, Portugal, Spain, Sri Lanka, Saudi Arabia, Philippine, Azerbaijan etc.
