This detailed product description presents the technical features and advantages of the Wieländer+Schill B1 Class H safety vacuum cleaner (Item No.: 932464), highlighting its suitability for safe application in explosion-hazard areas.
The B1 Class H safety vacuum cleaner is specifically designed for use in Zone 22 hazardous areas meeting the strict requirements of Class B1 dust rating. This device is critically important in work environments where the presence of dust poses an explosion risk. For safe operation, the vacuum cleaner has an anti-static suction hose (3.5 m) and built-in AntiStatic technology which effectively minimizes the risk of electrostatic charge when vacuuming hazardous and explosive dusts.
For maximum flexibility and functionality, the device comes with a rich accessory kit, including a tool adapter, filter element, and filter bag. Particularly outstanding is the 7.5 m long rubber mains cable which ensures convenient placement and mobility even over large work areas.
The vacuum cleaner can be further expanded as it can be connected to eccentric sanders, which significantly increases the spectrum of application areas, making it ideal for demanding and safety-critical workplaces.

The main advantage of the device is safe operation in potentially explosive environments. The Zone 22 marking guarantees that the vacuum cleaner complies with the European ATEX directives (Category II3D), which means it is suitable for collecting dust in areas where explosive dust is rarely present, but if it is, it will not cause an ignition source.
AntiStatic Technology: This special design prevents the discharge of static electricity generated in the suction system, which can be the most common ignition source in the case of explosive dusts.
Antistatic Suction Hose: The 3.5-meter hose does not conduct electrical charge, further increasing the safety level.
The 1500 W motor and the 3800 l/minute volumetric flow rate ensure that even finer, B1 category dust can be efficiently and quickly vacuumed. The 70 liter tank capacity reduces the need for frequent emptying, thereby increasing workflow continuity.
Large Work Area Coverage: The 7.5 meter rubber power cord allows for the positioning of the vacuum cleaner without the user having to constantly relocate the power source.
Strong Vacuum: The maximum negative pressure of -250 mbar guarantees the maintenance of suction power even when the filter is partially saturated.
The vacuum cleaner is suitable not only for basic extraction but can also be integrated into more complex systems:
Connection of Orbital Sanders: The included tool adapter enables direct connection to certain sanding tools, so dust is immediately extracted at the source, improving air quality and work precision.
Accessories: The filter element and filter bag ensure proper filtering and storage of dust, protecting the motor and the environment.
The device is made from durable materials such as plastic, stainless steel, and steel, ensuring a long service life even in harsh industrial environments. Despite the weight of 25 kg and the robust design, the vacuum cleaner is easily movable within the work area. The 59 dB(A) noise level contributes to a more pleasant working environment.
This safety vacuum cleaner is the ideal choice for automotive workshops, paint shops, and any industrial area where there is a risk of dust explosion and where reliable, high-performance extraction is required.
