Powertech, a bangalore-based organisation, manufactures ttwo-stage electrostatic filters are provided by powertech, a bangalore-based organization. These electrostatic, which filters particulates down to 0.01-micron level.These systems are highly efficient and are ideal for capture of welding smoke, oil/coolant mist and fine powders with the additional advantage of possible re-use of the collected oil/coolant or powder. Following are some of the technical features of these electrostatic filters which include:the pressure drop of the product is 3 mm wg; . These substantially use less wattage of motor/blower, typically 250 w per 1000cmh of airflow. Replacement cost of filters is nil since the equipment is fitted with permanent filters. Filters can be cleaned when saturated.Automatic indication of the trip circuit when the filters are saturated guards the motor from being burnt. For the function of these filter, it these filters requires minimum current for their function. These electrostatic filters find their applications in cnc grinders, lathes and machining centres for removal of oil/coolant mist. In pharmaceuticals theythese filters are useful in pharmaceuticals in capturing powder from tableting and capsuling. These filters are also useful are helpful in filtering dust in humidification system in textile industry and for controlling bacteria in operation theatres in hospitals.
