Volkmann INEX Vacuum Conveyors provide safe loading of bulk materials into hazardous areas, particular in the Chemical and Pharma Industries, where the loading of powders into reactors and stirring vessels is requiered. INEX systems can be used inside all gas and dust explosion zones. Initially material is sucked into the separator of the INEX system. Before the material is discharged, the transportation line is closed and the INEX system is set under vacuum. Then, the material inside the INEX system is areated with inert gas (for example Nitrogene) from the bottom and then released through the systems discharge valve. The concentration of Oxigen during discharge typically is below 7% or limited to such a value to not compromise the inert feed of the system. For the conveying of hybride mixtures, where the transfer of powders containing solvents, the entire vacuum transportation process with an INEX Vacuum Conveying system takes place under inert atmosphere. Volkmann INEX Vacuum Conveyors for hazardous applications and Explosion Zones free of ignition sources operate completely pneumatic without electricity completely electrical conductive design small interior filling volumes low transportation speeds no heat produced no hot surfaces no rotary parts easy to control and to operate. Volkmann provides profound expertise and support for all hazardous applications relying on our experience and knowledge. All systems have been designed for the specific demands of hazardous applications.

INFA-Jet IJS Filter series for dedusting in difficult filtration processes with adhesive, abrasive or combustible dusts. Area of application: The INFA-JET IJS series is a highly efficient aspiration filter that is particularly, but not exclusively, suitable for more demanding filtration processes with adhesive, abrasive or combustible dusts. Filter units in this series have a compact design with maximum filter surface area in a minimum of space. The series is designed for volume flows from approx. 2,000 to approx. 40,000 m³/h. The filter elements can be replaced quickly and easily via a large, front maintenance door. Advantages: ▫ Flexible modular system in modular design ▫ Pressure shock-resistant design up to 0.4 bar ▫ Design in accordance with Directive 2014/34/EU ▫ Filter medium: sinter-plate filter ▫ Quick filter change system ▫ Horizontal installation ▫ Residual dust << 1mg/m³ ▫ Housing for the installation of Rupture discs or flameless pressure relief ▫ Optional: H14 filter cassette as a secondary stage < 0,001mg/m³ ▫ Large maintenance doors ▫ Housing made of steel or stainless steel ▫ Dust Ex zone barrier in accordance with VDI 2263 Sinter-plate filter: Plate-shaped rigid filter made of sintered, porous polyethylene with low residual dust values and a long service life. Also available in electrically dissipative (antistatic) quality. Precoating: Coater systems are used to bind the adhesive components of sticky dusts by adding filter aids. The addition of filter aids can reduce the flammability of flammable dusts. This can protect the filters in demanding filtration processes and thus improve their service life.

Cartridge filters for dust removal from machines and workplaces.

INFA-Jetron IPF Cartridge filters for dedusting machines and workstations Area of application: Cartridge filters from the Infa-Jetron IPF series are used for centralized dedusting of machines and workplaces. They are particularly suitable for dry and free-flowing dusts. A choice of different basic modules in this system allows flexible adaptation to process engineering requirements. The basic unit only requires around 1 m² of floor space. The series is designed for volume flows of 800 to 8000 m³/h. Advantages ▫ Space-saving compact design ▫ Maximum filter area in the smallest space ▫ Design in accordance with Directive 2014/34/EU ▫ Filter media: filter cartridge with quick change ▫ Residual dust < 1mg/m³ ▫ Quick change optimized ▫ Optional: H14 filter cassette as secondary stage < 0,001mg/m³ ▫ Internal compressed air tank ▫ Steel or stainless steel housing New filter change system: ▫ Quick and easy handling ▫ Secure positioning and fixation ▫ Little effort required Options ▫ Additional units, e.g. fan, shut-off damper, rotary valve, level indicator in the dust collector ▫ Electronic control unit for time-controlled or differential pressure-controlled filter cleaning ▫ Control unit and motors for special voltages ▫ Hot gas version up to 160 °C ▫ Filter media in various qualities qualities (e.g. food-safe in accordance with Regulation EU 1935/2005 and EU 10/2011) ▫ Noise-reducing additional equipment for operation in noise-sensitive environments
