Centralized de-dusting system - Indpro

Indpro Engineering, Pune - Speciality Filter

Dedusting system for lower emissions

A centralized dedusting system is also known as dust collectors, bag filters, or bag house. In manufacturing plants, dedusting is necessary for a safety and better working environment. As a result, selecting the right filtration system becomes crucial.

Large capacity modern plants are designed in a way that the conveying and process equipment is centralized in one area. Instead of individual multiple-point filters, a common large scale filtration system is set up to gather the dust from various sources using a network of aspiration lines. The centralized dust collector draws process air through the filter media using an outside fan before releasing it into the atmosphere. When the filter medium is being cleaned, compressed air creates a shock wave throughout the length of the element to force the dust or cake to fall off the element's exterior and back into the filter hopper.

Centralized dust collector filters gather dust from a variety of locations, including bag dump stations, big bag stations, container unloading stations, mechanical conveyors, mixers, blenders, sifters, hoppers and silos, and packing machines.

There are various filter media types to choose from depending on the application, dust characteristics, temperature, and moisture level of the substance. The filter bags or cartridges are of removable and replaceable types.

Depending on the needs of the customer, our dust collecting system offers multiple levels of filtration, including HEPA filters, cyclones, bag filters, and cartridge filters. Depending on the type of arrangement and application, we can achieve emission levels as low as 5 mg/Nm3. Based on your requirements, our team can recommend the best dust collector for your operation.

Product Features

Inertial collection - Dust particles strike the fibres, which are placed perpendicular to the gas-flow direction, instead of changing direction with the gas stream.
Interception - Particles that do not cross the fluid streamlines get entrapped with fibres because of their larger particle size as compared to the pore size.
Brownian movement - Sub-micron particles get diffused, increasing the probability of contact between the particles and collecting surfaces.
Electrostatic forces - The presence of an electrostatic charge on the particles and the filter can increase dust capture.
Nozzle filters with automatic compressed air dedusting.

Types of filter elements in specialized dust collectors

Bag filter

Indpro’s specialty bag filters have capacities ranging from 2000 to 60,000 Nm3/hr to suit low, medium, and high-volume applications.
Our bag filters are expertly made to consume less energy and require lesser maintenance as compared to cartridge filters.
Filter changes for bag filters must be done from clean gas side (top mounting) by accessing through the maintenance top door.
Perfect for medium or high dust volumes.
Filter bags are available in diameters of 120 mm and 160 mm.
Available with various media options such as Polyester, Polypropylene, Aramid, Fiberglass, Ryton, etc. with/without PTFE lamination.
Built in automatic pulsing system is standard. Required cleaning pressure 5-6 bar(g).
Outlet emissions of up to < 5 mg/Nm3 can be achieved.
Ideal to be used for high efficiency separation to maintain low outlet emissions.

Cartridge Filter

Indpro’s specialty cartridge filters have capacities ranging from 2000 to 100,000 Nm3/hr to suit low, medium, and high-volume applications.
Our cartridge filters have a compact design to moderate airflow volumes within severe space restrictions.
Filter changes for cartridge filters are secure and simple and full changeouts may be completed without the use of special tools in under 30 minutes. They can be removed from raw gas side (bottom mounting) or from clean gas side (top mounting).
Ideal for low-to-moderate dust volumes.
Filter cartridges are available in diameters of 150/225/327 mm.
Available with various media options such as Polyester, Polypropylene, Aramid, Cellulose, Poly-phenylene sulfide, etc. with/without PTFE lamination.
Built in automatic pulsing system is standard. Required cleaning pressure 5-6 bar(g).
Outlet emissions of up to < 20 mg/Nm3 can be achieved.
Ideal to be used at restricted spaces as it offers good efficiency in terms of filtration area.
