Sakai Model BL-1005-02
Following the best-selling 1005 protective mask model, this is a Powered Air-Purifying Respirator (PAPR).
What is the Breath-Link Ventilation System?
The Breath-Link series is equipped with a ventilation function synchronized with the user’s breathing rhythm, known as BSFS. BSFS implements “silent blowing” during inhalation, which not only enhances protection but also minimizes breathing resistance and conserves power consumption.


1. Benefits of Breath-Link
- Easy Breathing
Minimizes breathing discomfort by adjusting the airflow in synchronization with the user’s respiratory rhythm. - Extended Work Duration
By restricting unnecessary noisy fan operation, the device consumes less power, allowing for longer continuous working hours. - Lightweight at approx. 270g
Due to low power consumption, a smaller battery can be used, reducing the total mask weight to approximately 270g for easy mobility.
2. Battery Drop Prevention
The mask features a “release lever” inside the battery compartment to secure the battery and prevent it from falling out.

3. Charger Replacement Parts
Replacement components include the battery charger, filter cover, and other accessories, ensuring convenient maintenance when needed.

Features
- Fit Checker
Allows for quick and easy seal checks thanks to the integrated fit checker mechanism. - Adjustability
Mask size and fit can be easily adjusted with the provided adjustable harness options. - High Airflow & Anti-Corrosion
Utilizes electrostatic filters to reduce operational noise while ensuring high performance. - High Elasticity and Durability
Employs SB/SA type harnesses known for superior elasticity and long-lasting durability. - Silicone Material
Made with highly durable and heat-resistant silicone for the facepiece. - Lightweight and Ergonomic
Lightweight design makes it easy to carry and perfectly suited for active work environments. - Auto ON/OFF
The fan automatically starts when the mask is donned and inhalation begins, and stops automatically when removed. - Alert System
Provides notifications for battery replacement via the “Airflow Regulation” fan alert. - Compatible with Welding Shields+
