Protective ventilation system SBL 30 Comfort Comfort

The newly developed SBL30 Comfort meets all the requirements of BG Information 581 and DGUV Information 201-004. Like all other Wölfle systems, the system is characterized by a high level of operational safety, optimal functional control, low operating costs and simple operation.
During development we focused on the essentials in order to offer the machine operator the best possible protection at a reasonable price.
Like the SBL30 Premium, this system was developed to protect the driver from toxic gases in landfills, composting plants, during renovation work or when disposing of military waste. Of course, it also protects against suspended matter such as asbestos, spores, fungi and bacteria thanks to the H13 suspended matter filter and the upstream cyclone pre-separator and is of course also suitable for odor filtering.

operation area

Typical areas of application are construction sites with a lot of dust or even asbestos, remediation areas with contaminated sites, landfills, composting and sorting plants and all other work areas contaminated with pollutants. With our system, your machine operator is optimally protected from toxic gases, pollutants and odors.

functionality

The contaminated air is sucked in via the pre-filter housing. The cyclone in the upper area separates the coarse dust particles. There is a G4 filter element in the pre-filter housing, which filters fine dust particles. The cleaned air flows via the fan to the main filter. When using the combination filter in its first filter stage (filter class H13), suspended matter is removed via the main filter. In its second filter stage, the gaseous pollutants are then absorbed in the activated carbon.
The cleaned air flows into the driver's cab via the air hose. The recirculating air filter device circulates the air in the cabin.
When the driver gets in and out, contaminated air may be introduced into the driver's cab. After the cabin is closed, these contaminants are removed during operation of the recirculating air filter system.
The system is put into operation and monitored via the control panel.
The beacon signals to outside personnel that the system is functioning properly.
