Tiger-Vac's double-marking ensures the right choice for ATEX Zone 22

Zone 22 poses a unique challenge when it comes to housekeeping. Equipment rated for Zone 22 can be used in areas where combustible dusts may, but are unlikely, to be present. If such dusts are present, they will be picked up by vacuum cleaners: the inside of the vacuum cleaner, therefore, becomes a zone 20 with its associated risks.

This is why Tiger-Vac works with double-markings. This allows us to evaluate and rate every aspect of our vacuum cleaners. Tiger-Vac is the only manufacturer using a double-marking system. When using a Tiger-Vac « Zone 22 » vacuum cleaner, you’re not just safe: you’re safer.

Be aware: When energized, any vacuum cleaner becomes an ignition source. Some vacuum cleaners currently advertised and sold as « ATEX Zone 22 » but not providing the proper equipment protection level are unsafe to be energized in a Zone 22 classified environment. Unsafe equipment in Zone 22 must be discarded as operation may lead to disastrous consequences for the workers.
