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 large physical movements, especially in confined spaces, such as tunnelling or building work, instead of work just sitting or standing with minimum body movement most of the time:
- The long hose and heavy belt-mounted power unit are troublesome to don and doff, and difficult to move around while doing highly physical work.
When you need to carry tools around your waist:
- The belt-mounted power unit prevents you from carrying tools around your waist.
When doing work with heavy dust:
- The bulky Versaflo system is difficult to clean, while the AYO WX FFM-LF PAPR system is much easier to clean and maintain.
When doing high-exertion work that causes very 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, for the AYO WX FFM-LF PAPR System, you can configure it into an AYO WX FFM-DS PAPR system, which provides a tight-fitting double-seal Full-face mask that can protect you well when the pressure in the mask goes negative briefly during very heavy inhalation.
When you are on a budget:
- 3M Versaflo is over 2 times the cost of the AYO WX FFM-LF P-Boost PAPR system. Why pay more for a product that is less suitable for doing the same job?
