inner lens safety on a NOVA 3 blast helmet
The inner lens on a blast helmet is the last line of defence. The inner lens is the only part that is designed for safety, the outer lens and the tear-off lens are designed to protect the inner lens from abrasion but not for operator safety. With no inner lens you could be in danger.
The inner lens should be able to withstand airborne debris striking the lens. To test the Nova™ Series helmet inner lens, a ball bearing is fired at the lens at a speed of 200 mph. After being subjected to this test, the Nova inner lens does not puncture. Does your inner lens have this guarantee of safety?
Many blasters decide not to use an inner lens because it takes as long as 3 mins to install on most helmets. To combat this, the RPB Nova 3 blast helmet inner lens can be changed in just 30 seconds.
