Similar to the S-655, the 3M™ S-657 Hood uses a double shroud design for its respiratory seal; wearers can select on their seal design based on personal preference. The wearer should tuck the inner shroud into a shirt or protective coverall, which allows excess air to be channelled over the body for additional comfort.
The 3M™ S-657 Hood offers head, face, neck and shoulder coverage as well as providing eye and face protection to EN166 - liquid splash and low energy impact (grade F) the same classification for impact resistance as safety spectacles! Manufactured using a general purpose, fabric, the S-657 is a cost effective, practical powered air solution.
When used in conjunction with 3M™ Powered and Supplied Air Systems the S-657 offers an assigned protection factor (APF*) of:
Jupiter APF= 40
Dustmaster APF= 10
TR-300 APF = 40
V-500 APF= 40
*Assigned Protection Factor (APF) as detailed in HSE HSG53.
These premium maintainable hoods are a highly cost-effective choice for some high disposal rate environments, as only the soiled hood fabric is replaced while the head harness and air ducting is reused.
The rigid ducting of the head harness provides a consistent air path, while the externally adjustable airflow control allows wearers to modify the airflow distribution to suit personal comfort needs.
The 3M S-Series Head Harnesses, through their sizing and adjustment options, will comfortably fit a broad range of head sizes.
Convenient hanging loop.
The Versaflo S-Series headcovers and hoods meet the highest respiratory performance requirements (TH3) for this type of product when used with 3M Air Delivery units. In addition they also provide eye and face protection to EN166 for liquid splash and low energy impact.
Visors have an excellent field of vision, particularly downwards, with reduced curvature for decreased reflections and glare.
Range of 4 fabrics to suit more applications and needs.
All wearers benefit from excellent airflow distribution for improved comfort and lower noise.
