Security controls on the SEAC full-face masks

Even though there is no specific European regulation governing the manufacture of full-face snorkeling masks, SEAC had its full-face masks tested by a third-party laboratory to certify the residual CO2 content while breathing.

[Certified by ITALCERT S.r.l. - date of issue:2019-10-25 - Notified Body n°0426 - Test report n°PPE156RP2739]

The tests consist of measuring the residual carbon dioxide within the mask at full capacity, introducing a mixture of air with a concentration of 5% CO2 into the circuit (CH1)

Two test modes:

- 25 breathing cycle per minute with a volume of 2.5 liters per breath. The maximum CO2 limit must be 1% (CH2)

- 10 breathing cycle per minute with a volume of 1 liter per breath. The maximum CO2 limit must be 2% (CH2)

For further information, ask us a copy of the official detailed results!

SEAC abides by two fundamental principles in designing its full-face snorkeling masks:

That's why has also developed a series of specific tests that comply with the values set forth by the following European regulations: EN 1972:2015 establishes the requirements for the design and manufacture of snorkel tubes, limited to breathing effort; EN 16805:2015 establishes the requirements for the design and manufacture of dive masks; EN 136:2000 establishes the minimum requirements for the manufacture of full-face respiratory protection masks, limited to tests checking the CO2 in inhaled air; EN 250:2014 regarding open-circuit compressed-air self-contained breathing apparatus and its components, limited to tests checking the CO2 in inhaled air, related to the full face masks or oro-nasal half masks for SCUBA diving. In the SEAC labs , batches of full-face masks are tested with Ansti machines , specifically to measure the dynamic performance of human breathing , and with specific SEAC equipment to check levels of CO2 in the air inhaled through the masks.- the user should need to employ the least possible breathing effort , comparable to natural breathing , out of the water and in a relaxing situation; - and the level of residual carbon dioxide CO2 inside the skirt while inhaling must be well below the safety limits .

The evolution of full-face masks for snorkeling. Natural breathing through your mouth and nose, with the lowest breathing effort in its category. Completely separate circuits for fresh air (IN) and exhaled air (OUT). Exhaled air is expelled through a SEAC patented exhaust circuit. Anti-fogging system guaranteed by the continuous flow of incoming air. One-way valves with a larger cross section for effortless exhalation and effective expulsion of residual CO2. The smaller internal volume offers an even broader field of vision and an optimization of residual CO2. A large anatomical hypoallergenic liquid silicone skirt with a shape designed to adapt to every kind of facial contour ensures the very best seal, safety, and comfort. The snorkel features a Dry Top to prevent water from entering the tube.

SEAL quality | The SEAL libera contains all the most popular features of the SEAL full Face mask: wide panoramic anti-fog screen, patented separate channel breathing system, Dry top snorkel, purge valves, high quality soft hypoallergenic silicone. A style Eye | the SEAL libera is available in 3 sizes depending on the distance between nose and chin; . the small size of the XS-S body shell lightens the mask, improves comfort and makes it more pleasant on small Faces. Easy to use | the SEAL libera has a perfect fit thanks to the adjustable silicone straps both in the upper and the lower part of the head. The quick-release buckles on both sides of the mask allow you to remove SEAL libera with just one hand. Safety first Of all | like all SEAL full Face Snorkeling masks The libera is tested to measure breathing performance and control Co2 levels. The SEAL full Face masks are the best in the category with a totally natural and effortless breathing quality, and.
