Airflow where your hard hat can't provide it

FAQ
Questions about the HVN-400U
The specification and compatibility questions that come up most.
Does this include a hard hat?
No. It attaches to any standard full-brim hard hat you already own. Confirm your hard hat manufacturer permits brim-mounted accessories before use.
What powers it?
Standard AA batteries out of the box. It can be upgraded to a ZIPPKOOL LIMINI01 lithium-ion battery, sold separately, for longer and more powerful runtime.
Is this ANSI/ISEA 107 rated?
No. It's a hi-vis colored accessory, but ANSI/ISEA 107 applies to garments, not helmet attachments. It does not replace certified head protection.
