Pulse Jet Bag Filter System
A filter-cleaning apparatus utilizes pulsed air to remove matter collected on a first surface of a filter. Reverse flow loosens the material which is collected in a hopper on the upstream side of the filter. The collected matter may then be combusted in the hopper so that the amount of material collected is minimized. The pulses are directed at the filter with a controlled shape and time to optimize reverse pulsing. Pulsing occurs while the thermal exhaust flow continues so that operation of the engine is not interrupted. A number of valves may be utilized to clean one or more filters.
MFP Manufactures and Supplies of Pulse Jet Bag Filter Systems with below feature:
- High Collecting Efficiency
- Low pressure drop
- Economically Designed
- Low Maintenance and Operative Cost
Electrostatic Precipitator Systems
Electrostatic precipitation removes particles from the exhaust gas stream of an industrial process. Often the process involves combustion, but it can be any industrial process that would otherwise emit particles to the atmosphere. Six activities typically take place:
- Ionization – Charging of particles
- Migration -Transporting the charged particles to the collecting surfaces .
- Collection - Precipitation of the charged particles onto the collecting surfaces
- Charge Dissipation - Neutralizing the charged particles on the collecting surfaces
- Particle Dislodging –Removing the particles from the collecting surface to the hopper
- Particle Removal – Conveying the particles from the hopper to a disposal point .
MFP Supplies of Electrostatic Precipitator Systems with below features:
- Low Pressure Drop
- Low sensitivity to high temperature and aggressive gases
- High Collecting efficiency well in excess of 99%
- Low Maintenance
Filter Bags/Dust collector cages
For optimum filtration performance we manufacture high quality dust collection conventional bags. These dust collection conventional bags are made from minutely selected media as per the process industry. Different types of media such as needle felt, monofilament and multi-filament are used to develop these bags. With the support of filter cages, these are placed in Dust collector cages. These bags are more effectual in minimizing dust emission level as per requirement of industries. Through the top chamber all the solid contaminants get deposited. With the help of shaking mechanism or reverse pulse jetting mechanism, the particles retained at the outer surface get collected at the bottom.
MFP manufactures and Supplies the widest selection of filter bags for practically any application and for any OEM style bag house.
Available Filter media like Polyester, Polypropylene, Homopolymer, Co-Polymer, PPS(Ryton),Nomex, Fiber Glass, PTFE, P-84 with finishes for enhance the performance of bag like Water repellent, Water and Oil repellent, Antistatic, Flame retardant, PTFE Coated, PTFE Membrane Laminated.

Bag Supporting Cages and Ventury
Pulse-jet style bughouses are designed to utilize fabric filter bags with internal support structures commonly referred to as cages. Cages provide a means of holding the filter bag open during the particulate collection cycle. Cages must be strong to withstand the pressure from the filter bag exerted during the particulate collection cycle.
MFP provides a wide range of configurations to best fulfill your needs in MS, GI, SS304, SS316 and SS316L with 8, 10, 12, 16 and 20 vertical wires and any spacing of horizontal rings made by 3mm, 4mm and 5mm wire diameter.
We can also supply Ventury made of MS, Aluminium, Cast Iron and Cast Alumimium in any type of design
Solenoid Pulse Valve and Sequential Timer
Pulse-jet cleaning bag Filter system utilise diaphragm valves to pass compressed air from the air supply lines and manifold into the blow piped within the bag filter. These diaphragm valves are usually actuated with electrically operated pilot solenoids.
Solenoid Valves are available in ¾” to 2” suitable for 24V DC and 110V/230V AC.
Sequential timer controls are important for effective filter bag cleaning. Excessive differential pressure, increased fan power consumption, reduced production process air flow, and decreased filter bag life can result if timer controls are not functioning properly.
Sequential timers are available from 3 to 40 channels.
Pleated / Cartridge Filter Bags
MFP supplies Deep Pleat Cartridges increase effective filter area significantly over conventional pleated synthetic media. Deeper pleats are allowable media which prevents collapsing of pleats under operating pressure. This unique design uses staggered dimpling on the filtering side which, unlike other dimpling patterns, provides unrestricted air flow and pulse cleaning at the extreme ends of the pleats.
Filter media available in spunbond polyester and polypropylene, PTFE membrane, Aramid, and antistatic (aluminized) media.
Rotary Airlock Valves and Screw Conveyor
We have in store for our clients, a highly functional gamut of rotary air lock valves that is used to minimize the system loses, while transferring the material between the vessels with different pressure or a volumetric feeder for metering material at specified low rates.

High voltage support insulators mechanically support and electrically isolate the discharge electrodes from the grounded ESP casing and collecting curtains. Support insulators are designed for high compressive strength to support the loads imposed by the high voltage electrodes and associated framing. Providing the primary application point for high voltage and located in close proximity to the gas stream, high voltage support insulator design must also consider the voltage applied and operating environment.
MFP supplies support insulator suitable for all type of ESP like Thermax, Alstom, ACC, VT Corp, ELS-Elex etc.
We can also Supply various insulator for any type of ESP as follows:
Shaft Insulators, Pin Insulators, Bust Duct Insulator , Wall Through Bushing insulators, Antis way insulator
A typical collecting plate used in electrostatic precipitators.
- Collecting plates are made from rolled steel, and are welded together in the factory to reduce the installation time at the jobsite. Each plate contains electrodes which are positively charged. When the particulate gas enters the electrostatic precipitator and is struck with a negative charge electrode, the positively charged plates act as a magnet and pull the particulate gas to them.
- The plates have both top and bottom stiffeners and plates which allow better mounting and the ability to deal with more abuse from the rappers. The plates are arranged to form a series of gas passages
- There can be anywhere from 30-35 passages inside the electrostatic precipitator shell. The plates are placed parallel to the incoming particulate gas. MFP supplies collecting plates suitable for all type of ESP like Thermax, Alstom, ACC, VT Corp, ELS-Elex etc.
