3M Speedglas Noise-Reducing Breathing Tube for Adflo PAPR, SG-50W

3M Speedglas SG-50W Noise-Reducing Breathing Tube for Adflo PAPR

The 3M Speedglas SG-50W noise-reducing breathing tube is the required tube when the Adflo respirator is used with the high-efficiency filter and organic vapour cartridge. Designed for the most demanding welding conditions, the SG-50W incorporates acoustic insulation that reduces the noise transmitted by the Adflo turbo unit to the mask, significantly improving the welder's hearing comfort during extended use.

3M manufacturer code: 7000039456, model: SG-50W

The SG-50W is the premium model in the Speedglas Adflo tube family. It is mandatory in configurations combining the P3 high-efficiency filter and the organic vapour and acid gas cartridge (OV-AG). Its acoustic insulation is particularly appreciated in high-noise industrial environments where the Adflo turbine noise can become bothersome over long periods.

Like other tubes in the range, the SG-50W is compatible with the SG-15 protective cover to extend its service life against welding spatter and sparks.

Advantages

Acoustic comfort and performance

• Built-in acoustic insulation: the SG-50W reduces the Adflo turbine operating noise transmitted to the mask, providing superior hearing comfort during long welding sessions in noisy environments.

• Mandatory with OV-AG cartridge: the SG-50W is the only Speedglas tube approved for use with the P3 high-efficiency filter combined with the organic vapour and acid gas cartridge. It ensures the airtightness required for this configuration.

• Robust construction: designed for the most severe exposure conditions, the SG-50W offers durability and reliability even in environments combining heat, chemical vapours and welding spatter.

• SG-15 cover compatible: the SG-15 protective cover can be added over the SG-50W for additional mechanical protection against spatter and sparks.

Application and compliance

The SG-50W tube is designed for 3M Speedglas Adflo systems. It is specifically required when the configuration includes a P3 high-efficiency filter and an OV-AG chemical cartridge, ensuring the airtightness and performance of the respiratory system under these advanced exposure conditions.

FAQ - Frequently Asked Questions

Why is the SG-50W mandatory with the OV-AG cartridge?

When the Adflo is configured with the P3 high-efficiency filter and the organic vapour and acid gas cartridge (OV-AG), the pressure in the respiratory circuit differs from standard configurations. The SG-50W is approved by 3M to ensure the required airtightness and performance in this configuration. Using a different tube in this configuration is not recommended by the manufacturer.

Can the SG-50W replace the SG-30W or SG-40W in standard use?

Yes, the SG-50W can be used in place of the SG-30W or SG-40W in any standard Adflo configuration. Its acoustic insulation is an advantage in all cases. However, its price is higher; it is therefore generally reserved for chemical cartridge configurations where it is mandatory, or for welders particularly sensitive to turbine noise.

Does the SG-50W acoustic insulation replace hearing protection?

No. The SG-50W acoustic insulation reduces the Adflo turbine noise transmitted to the mask, but does not replace hearing protectors against ambient noise in the welding environment. Earmuffs or earplugs remain necessary for hearing protection against external noise.

Complementary Suggestions

Complete your welding equipment with gloves Endura goatskin and Kevlar (G625) for MIG/TIG welding, mittens 11-in leather (G602), earmuffs H10P3E 27 dB cap-mount (OPH10P3E), eyewear OX safety glasses (YA12166) and a headgear 3M for CSA hard hats (YPH24).

To protect and transport your Adflo system, add an cover SG-15 (RSG-15) against welding spatter, a bag SG-90 (RSG-90) for safe transport, and a faceshield IR3.0 polycarbonate (YV96R3) for additional face protection.
