Co2 Absorbent Application:

• Used to absorb expired Co2 during Anesthesia (in operation theatres).
• Used for removing Carbon Dioxide from oxygen-based metabolism, in estimation respirators, breathing apparatus, diving rebreathers.
• Removes Co2 from manned closed atmospheres, such as submarine, and closed circuit breathing apparatus, such as rebreathers.
• It is extensively used in navies, for use by divers in submarines.

Product Features:

Non-Potassium Hydroxide
Nafern sodium lime main ingredients are calcium hydroxide and sodium hydroxide, Non-Potassium hydroxide, which can effectively reduce the generation of nephrotoxic substances in the using process

High Hardness And Low Dust Rate
High-quality raw materials and advanced dust suppression technology to ensure the dust content less than 0.2%, Rigid particles not easy to be shattered before and after use,thus effectively reduce dust pollution and improve ventilation.

Cylindrical irregular Particles
Compared with other shape particles, Cylindrical irregular particles provides a larger surface area, can make soda lime get better use,for better Co2 absorption

Excellent Co2 Absorption Capacity
Clinical application data show that Nafern sodium lime is efficient for 10 hours working time per Kg,(tested in general operation,actual use depends)

Sensitive Color indication
Pink to white or white to purple, the color changes significantly, providing great convenience for clinical applications.

Low Risk of Anesthesia
Pay more attention to thrifty and environmental impact of anesthesia surgery, to reduce the risk of anesthesia and provide perfect results.
