The Stanelle Filter Type PNEUFIX is suitable for the de-dusting of pneumatically or mechanically conveyed filling, continuous and discontinuous, or conveying-processes in silos or bunkers. The PNEUFIX performs due to its rugged construction and its wide range of applications. The flanged filter housing of lacquered steel- or stainless steel sheet metal provides excellent protection during the final surge of the filling process. Through the integrated filter controls with differential pressure controlled 'on' and 'off' switching points, the continuous, around-the-clock PNEUFIX operation is made possible. Because of the high quality, star-shape folded, non-woven polyester covering of the filter cartridges, an especially low residual dust content is achieved. The filter cartridges lend themselves to many different applications and for use with media temperatures up to 130°C. The de-dusting of conveyor belts, elevators or other dusty apparatus is possible in conjunction with a supplemental exhaust fan. All parts coming in contact with the product can be designed for use with foods. Explosion-proofing a fully pneumatic filter control, or magnetic valves with explosion-proofed coils can be specified. As a special model, the PNEUFIX can be supplied in vacuum- or pressure resistant version as well as in heated or insulated design.
The PNEUFIX is regulated by a very economically working, fully automatic, differential pressure controlled filter regulating unit. This is internally wired to the filter, and permits free selection of the interval periods. As a result, optimal adaptability for each application is achieved. The 'on' and 'off' switching points for the start and end of the cleaning cycles as well as the beginning of the secondary cleaning cycle can be set individually on the filter control unit. The filter control unit is programmed for each individual application.
It assures the most economical compressed air consumption and prolongs the service life of the filter cartridges through the optimization of the cleaning cycles. Low maintenance costs result not only from the large inspection opening (400 x 300 mm), which provides rapid checking of the filter cartridges by means of the star grips, but the checking or exchange of the filter cartridges can now be done without tools. Responsible for this is the novel design of the weather hood. A simple catch permits the complete folding-back of the weather hood with its integral cleaning system. The filter cartridges are cleaned by using a fast bleeder valve which assures optimum filtration even during the cleaning cycle. The PNEUFIX, including a pressure reducing valve, is operational immediately after connecting to 110/230 V-AC power supply and compressed air at 3-5 bar.
The Stanelle-PNEUFIX can be supplied in two models:
- For pneumatic filling
- For mechanical filling
