3M Half Facepiece Reusable Respirator 7502, Medium (NIOSH) – Features Cool Flow Valve, Dropdown Suspension, and Dual-Airline Bayonet Compatibility
Product Description
Model and Design
The 3M 7502 is a medium-sized half facepiece respirator that is designed for repeated use. It is labeled with the NIOSH designation, indicating that it meets the standards set by the National Institute for Occupational Safety and Health for half facepiece respirators.
Reusable Half Facepiece
This respirator is constructed to allow for cleaning and reuse. The half facepiece design covers the nose and mouth, providing a seal that isolates the wearer from airborne contaminants. The medium size is intended to fit a range of face shapes, and the overall construction is consistent with the 3M brand’s approach to reusable respiratory protection.
Cool Flow Valve
A key component of the 3M 7502 is its cool flow valve. The valve is positioned on the exterior of the facepiece and is designed to facilitate airflow. When the wearer inhales, the valve opens to allow air to pass through the respirator. The cool flow feature reduces the amount of heat that accumulates in the breathing zone, helping to maintain a more comfortable breathing experience.
Dropdown Suspension
The dropdown suspension system is incorporated into the design to support the respirator during use. This feature allows the respirator to be hung or positioned when not worn. The dropdown mechanism helps maintain the respirator’s orientation and protects the facepiece from damage while it is stored or transported.
Dual-Airline Bayonet Compatibility
The 3M 7502 is compatible with bayonet attachments that use dual-airline connections. Bayonet connectors are a common interface for attaching filters or other accessories. Dual‑airline capability means that the respirator can connect to two separate filter lines simultaneously, allowing for a flexible setup that can accommodate different filter combinations.
Compliance
The respirator’s NIOSH designation signals that it has undergone testing for fit and filtration in accordance with NIOSH standards for half facepiece respirators. This compliance ensures that the respirator meets regulatory expectations for protection when used in accordance with the manufacturer’s instructions.
Summary
The 3M 7502 medium half facepiece respirator combines a reusable construction with a cool flow valve, dropdown suspension, and dual‑airline bayonet compatibility. It is manufactured in a medium size and is NIOSH certified. The design features are intended to provide a reliable, comfortable, and flexible protective solution for users who require a half facepiece respirator that can be reused and adapted with different filter accessories.
