FILTERING BAGS

INJECTOR COLUMNS

CONE WITH SOLENOID VALVE

Membrane valve serves controlling the flow of compressed air to the injector. Solenoid valve receives pulse signals and opens the diaphragm, which opens the line of compressed air. As a result, the pressure in the injector column equals, and follows the cycle of cleaning of filter bags.

To ensure the most optimal production processes while reducing the risks it is important to remove flue gasses, vapour and oils from the air as well as dust particles from the area of working machinery and the floors.

We offer solutions by means of filtering, spot suction, separating and recycling of all types of dust, transporting of materials, suction of smoke and suction in terms of cleaning in general.

Our experts are at your service all the way from counselling, planning and designing to the final realisation.

In terms of their construction, the PJS filters are dry bag filters. The bags are automatically cleaned using compressed air under 5 to 7 bar of pressure and a special electronic programmer which is set to an optimal cleaning programme so that it ensures quality and permanent operation of the filter.

Technical description:

Filter cartridges can be cleaned completely with compressed air impulses of 5 to 7 bar. The filter`s own electronic controlling system activates electropneumatic valves of column injectors based on the measurements of the differential pressure between unclean and clean gasses inside the filter. With the optimal setting of the program for the cleaning procedures, the filter will function permanently and reliably even under the most difficult conditions when severe dust is present. The time of injection of compressed air into an individual set of bags is very short, lasting from 0.016 to 0.1 second. Pauses between individual fillings are 10 to 250 seconds long.

Some of our specific features

• The built-in ventilator results in smaller outer dimensions of the filter housing and therefore there is also no need for seperate piping between the filter unit and the ventilator.
• Built-in sound absorber.
