OTT Tubular Membranes – Quality Made in Germany
OTT tubular membranes are available in EPDM (FLEXNORM®) and silicone (FLEXSIL®).
FLEXNORM® – Bioresistant and Rugged
FLEXNORM® membranes are recommended for use in municipal wastewaters. Made from high quality raw materials including a biologically resistant plasticizer, they provide long service life even at air temperatures up to 80 °C (176°F).
FLEXSIL® – Efficient and Durable
FLEXSIL® membranes are recommended for use with challenging wastewaters as well as in aeration systems requiring high efficiency and long service life. FLEXSIL® membranes are suitable for applications at high submersion depths, in heavily polluted wastewaters and at compressed air temperatures up to 140°C (284°F). Made of plasticizer-free materials of construction, they are not subject to embrittlement and are fully resistant to bioslime, a wide range of chemicals as well as oils and greases.
