Feature

A safer, healthier working environment where harardous fumes and airborne contaminants are removed.

• No replacement of the electrostatic modules for the lifetime of the equipment.
• Low running cost. High filter efficiency, low pressure drop.
• Can be incorporated into existing air flow systems with minimal effect on the overall pressure or air flow capacity of the system.

Applications

These modular filters are used for custombuilt applications & can be added module by module to suit various air flow rates. These modules are used as primary filters for Class 100,000 Clean Rooms & as Prefilters for higher Class levels of Clean Rooms. When used as pre-filters for higher class levels, they can increase the life of the terminal filters. The total pressure drop as compared to conventional pre-filters is negligible. These filters can be used in a centralised system for removal of fumes, smoke, oil mist, coolant mist, dust and fine powders from many in - plant industrial processes which generate pollutants rendering the shop floor unhealthy.

How It Works

Each filters module can handle an air flow rate as specified. The required quantity of modules are placed in an MS painted enclosure. The air inlet side is placed in the air stream using a suitable adaptor ducting. The power pack feeding the electrostatic voltages to the Modules is separately mounted in a control panel near the MS enclosure with the electrical connections made through conduits. Prefilters and post filters are placed before and after the electrostatic filter modules. Dust and fine particulates are sucked into the filters modules with the air stream. These first enter the prefilters which prevent large particles entering the Modules. The fine particles then enter the Modules where, between a series of parallel aluminium plates, they receive a high positive charge, The positively charged particles then pass through another series of negatively charged aluminium plates. Here, the particles are attracted to the oppositely charged plated and stick to them like iron filings to a magnet, but with a difference - the particles remain adhered to the plates even when the electrostatic filter is powered off. The clean air, devoid of particles, escapes through the after filters. The post filters help in distribution of the air flow through the electrostatic filter modules.
