Product catalog summary

Overview
The document outlines the technical specifications and operational guidelines for the SQUARE FILTER series, which are designed to handle dust in intake air using cartridge filters. These filters employ a textile filter medium and utilize backpressure blast-cleaning of cartridges to maintain efficiency.

Operation
Dusty air enters below the cartridges, where heavier particles fall into a hopper. The air then moves through the cartridges, depositing dust on the outside. Compressed air blasts clean the cartridges, and the detached dust falls into the hopper for disposal. Solenoid valves, controlled by an electronic timer, manage the air pressure blows.

Technical Features
The filters are compact due to a high surface-to-volume ratio and maintain high filtering efficiency, even with fine dust particles. Cartridges are cleaned using reverse-flow air blows, controlled by an electronic sequencing board. The standard configuration allows for cartridge replacement from the top, reducing maintenance time. The filters operate at a maximum temperature of 70°C and use high-quality non-woven fabric cartridges.

Applications
The filters are suitable for harsh conditions and can be used in industries such as chemical, food, metallurgy, and more. They effectively handle a wide range of dust types, including epoxy materials, cement, and inorganics.

Compressed Air Consumption
Guidelines for calculating compressed air consumption are provided, emphasizing the use of a differential pressure switch to optimize air usage.

Standard Features and Accessories
The standard filter includes an external body with legs and a hopper, and a compressed air washing system with solenoid valves. Optional accessories include maintenance platforms, manual guillotine dampers, and differential pressure switches for automatic cleaning.

Pressure Loss and Filter Selection
Initial pressure loss is 500 Pa with clean cartridges, increasing to 700 Pa with dirty cartridges. Formulas are provided for selecting the appropriate filter size based on flow rate and material type.

Technical Specifications
The document includes a table detailing flow rates, cartridge dimensions, filtering surface area, solenoid valve specifications, and compressed air consumption for various filter sizes.

Specifications
Detailed specifications for cartridge filters include dimensions, weight, outer diameter, cartridge height, number of folds, folding depth, and filtering surface. The filters are designed for high-efficiency applications in heavy-duty conditions.

Applications
These filters are suitable for use in various industries such as chemical, foodstuff, metallurgic, petrochemical, cement, ceramic, and foundries. They are effective in reducing fumes and dry powders from materials like epoxy, cement sand, inorganic chemicals, and metallic sandblasting.

Compressed Air Consumption
The document outlines the calculation of compressed air consumption for the filters, providing formulas and sample calculations. It emphasizes the importance of using a differential pressure switch for efficient air consumption.

Standard Filter Unit Includes
The standard unit comprises an external body with bearing legs and hopper, an air-pressure washing system with a solenoid valve, and a sequence control panel.

Accessories
Accessories include step irons, manual sash-type gates, wheeled containers, stellar valves, and differential pressure switches for automatic cleaning control.

Load Loss
The document specifies the load loss for clean and middling dirty cartridges, which are 500 Pa and 700 Pa, respectively.

Determining Filter Size
Formulas are provided to determine the correct size of a bag filter based on design flow rate and polluting material. The technical department is available for assistance in selecting the appropriate filter size.

CONSUMI DI ARIA COMPRESSA Per una rapida determinazione dei consumi di aria compressa, abbiamo riportato nella tabella di pagina 3 consumi minimi e massimi consigliati, riferiti ad uno sparoӔ di 200 m/s. con aria compressa a 5 Bar ed un tempo di pausa di 360 secondi mas- simo e 120 secondi minimo dopo il quale si ritorna alla stessa elettrovalvola. Per un calcolo preciso del consumo di aria com- pressa, vi indichiamo il consumo di una singola valvola nel tempo di un secondo: Diametro 11/2 - 950 Nl/s. a 3 Bar Ԗ 1085 Nl/s. a 5 Bar Diametro 2 - 1520 Nl/s. a 3 Bar Ԗ 1735 Nl/s. a 5 Bar Calcolo consumo...

OPERATION The Deduster Series SQUAREFILTER consists of cartridge filters, suitable for the handling of the dust in the intake air. Dedusters use a filter element of textile structure, with backpressure blast-cleaning of cartridges. The dusty air enters an areaunder the cartridges in a tangential way and it loses its speed and the heavier parts, carried by the fluid, fall into the hopper.The intake air flows through the cartridges with upward lift motion, thus leaving the polluting dust on the cartridge outside. The cartridge jarring because of the compressed air helps the detachment of dust from...

CONSUMPTION OF COMPRESSED AIR In order to quickly determine the compressed air consumption, we have indicated in the table on page 3, the minimum and maximum recommended consumption rates, referred to one "blowing" shot of 200 m/sec, at 5-bar pressure and with dwell time ranging from 120 seconds minimum to 360 seconds maximum, with subsequent return to the same solenoid valve. For a precise calculation of the compressed air consumption, consider that the consumption of each valve within one second is: 11/2 diameter - 950Nl/s. at 3 bars Ԗ 1085 Nl/s. at 5 bars 2 diameter - 1520Nl/s. at 3 bars Ԗ...
