Microperforated hose for the efficient transfer of gases (air, oxygen, nitrogen, etc.) into both fresh and saltwater. Designed for the generation of fine, homogeneus microbubbles, without the need of an external power source. The design principle is such that when pressurized, the micropores open up, producing fine bubbles. When the gas supply is closed, and the internal pressure diminishes, the micropores close down in order to prevent the entrapment of water and dirt particles within the hose, ensuring the optimal utilization of gas and favouring long-term maintenance. Made of flexible polymers, self-locking polymeric cover that does not contain (EPDM), increasing resistance to aggressive chemicals. Incorporating a special textile coating in order to improve mechanical hidrostability.
