The Simulated Workplace Protection Factor (SWPF) was conducted by Inspec International Ltd. in January 2005. The object was to verify the Nova 2000 Abrasive Blasting Supplied Air Respirator was capable of providing an assigned protection factor of at least 1,000 during simulated workplace exercises. As a result of the SWPF test the Nova 2000 achieved a lower 5th percentile greater than 250,000. According to OSHA SWPF's should be divided by a safety factor of 25. As a result tests concluded the Nova 2000 will provide an Assigned Protection factor of APF 10,000. The study demonstrates the Nova 2000 is capable of achieving SWPF of greater than 10,000 and of supporting an assigned protection factor of APF 1,000.
