Napotec® Molecular Sieve Wheel Typical Project Application Case
Qingdao Napotec® Environmental Protection Co., Ltd. (hereinafter referred to as Napotec® Environmental Protection) produced the first molecular sieve rotor product in China in March 2014. With its outstanding performance such as strong adsorption selectivity, high hydrophobicity, strong adsorption capacity, large adsorption capacity, and high temperature resistance, it has been favored by many enterprises. As of 2026, it has successfully provided waste gas treatment solutions for 3,500+ enterprises.
Here are typical project application cases:
