The "BAGPULSE" collector design of offers either top entry or hopper entry to meet the needs of your applications.

For fine dust (such as talc) on applications with low dust concentrations and with higher air-to-fabric ratios, top entry is more suitable. Top entry generates a down flow of air throughout the collector, due to which it aids the movement of particles towards the hopper.

In case of course dust (such as sand, etc.) and high dust loads, hopper entry is preferred. Heavy particles naturally gravitate to the hopper.

The filter bags in the "Bagpulse" collector are continuously cleaned with pulses of compressed air which are initiated by an electronic sequential timer. Small volumes of high pressure compressed air are directed from a reservoir tank through solenoid valves and nozzles.

As the burst of air passes through the venturi at the top of each bag, it induces a larger volume of additional air into the clean face side of the bag, inflating the fabric bag and breaking the dust layer on the outer face of the bag. The fabric gets a secondary cleaning as the pulse bounces back up the bag.

Pulse-jet cleaning provides an effective means of reconditioning the fabric without interrupting the normal airflow through the filter system. Since the pulse-jet collectors operate at higher filtering velocities than the corresponding fabric collectors which are cleaned either by mechanical shaking or low pressure reverse air.

In most of the conventional bag filter systems filter bags are removed from the top side, which means first the top assembly, including venturies, etc., has to be opened or dismantled, and then each bag has to be lifted up. The operation requires several persons working for several days. Moreover, the user has to ensure that the height of the ceiling should be at least double the height of the bag filter system.

Bagpulse from SANTONI are designed in such a way that the bags can be removed from the side panels of the collector, without having to dismantle any part, which means that the bags can be removed by a single person in a matter of a few minutes.

Since the bags are continously cleaned the pressure drop is very low and almost constant. Though the pressure drop will depend upon factors like air-to-fabric ratio, temperature of air, dust loading, finess of dust, etc., normally it will range between 75 to 150 mm WG.

SANTONI’s BagPulse collectors are designed for optimal use of compressed air for bag cleaning. The actual air consumption will depend upon various parameters of the final applications, such as dust loading, air-to-fabric ratio, type of filter media used, etc.

The standard material used for the construction of BagPulse collectors is CRC mild steel treated for rust prevention, double coated with red oxide primer and painted in color of your choice.

Special materials of construction, like, SS, PVC, FRP, etc. can be used to meet the application requirements.

The system is built with self-supporting strong structure out of steel sections. The ground clearance under the hopper outlet flange, as a standard is kept at 1200 mm, though it can be designed to provide any clearance as per your requirements.

For general applications heavyweight "Non-woven, needled, felt media" is used for high collection efficiency and long life.

Felts with special surface finishes to suit physical and chemical nature of the the dust to be handled and humidity and temperature of the air, are also available.

Explosion vents, to prevent loss due to explosion accidents, are fitted as a standard.
