When should AYO WX FFM-LF PAPR System be used instead of 3M Versaflo TR-315A+ PAPR Kit with a 307C helmet?
When doing work requiring frequent donning and doffing and physical movements, such as tunneling or building work instead of work just sitting or standing for a long period:
- The long hose and heavy belt-mounted power unit are a nuisance to don and doff, and for doing mobile and highly physical work.
When doing work with heavy dust:
- The bulky Versaflo system is difficult to clean, while the AYO WX FFM-LF PAPR system is far easier to clean and handle.
When doing high-exertion work that causes heavy breathing:
- The Versaflo will not provide protection when you over-breathe the blower with a peak of 205 L/min. For example, you may well breathe over 250 L/min doing heavy work, which will cause negative pressure in the face shield at the initial phase of inhalation. Due to the loose-fitting nature of the 307 helmet, you will breathe in harmful dust or gas easily. In this situation, if you have an AYO WX FFM-LF PAPR System, you can configure it into a AYO WX FFM-DS PAPR system, which has a tight-fitting double-seal Full-face mask that can still protect you when the pressure in the mask goes negative briefly during inhalation.
When you are on a budget:
- The Versaflo is over 3 times the cost of the AYO WX FFM-LF PAPR system. Why pay so much more for a product that is not as suitable for doing the same job?
