Straight answers to the questions people ask most when choosing a powered air headtop with a safety helmet.
It suits work with dust and particles combined with head and face hazards, such as grinding, sanding, cutting, fettling and heavy fabrication. The visor protects the face from flying particles, and the shell protects against knocks, depending on its rating.Not every headtop is suitable for welding. Welding needs protection against the arc, which calls for a proper welding filter, and a headtop without one must not be used for it. Check the data plate, markings and manual for your own headtop to see exactly what it is approved for.
No. Headtops are approved for use with particular blower units, filters and breathing tubes, and the protection rating only applies to approved combinations. The connectors may also differ between generations.Check the maker's compatibility list for your blower. Do not mix parts that are not approved together.
The helmet shell protects against falling objects and knocks to the head, within its rated limits. It may also give protection against other hazards depending on its rating, such as heat or electrical contact.Check the markings on the shell and the maker's instructions to see exactly what it covers. Replace the helmet after a significant impact, even if no damage is visible, and at the end of its stated service life.
With the right filters fitted and the blower running, it protects against particles in the air, up to the protection factor the maker gives for the approved combination. It does not protect against gases or vapours unless you are using suitable gas filters.The filter you need depends on the hazard, so check your risk assessment and the maker's guidance.
