The HL 138N is a flush-mounted air conditioner condensate siphon designed for safe and reliable condensate drainage into the sewer system. Suitable for Ø20–32 mm pipes, this concealed AC condensate trap effectively prevents sewer odours from entering indoor spaces while providing efficient condensate removal for residential, commercial, and professional HVAC installations.
Its compact housing with an installation depth of just 60 mm makes it ideal for concealed wall installation in both new construction and renovation projects. The integrated 50 mm water seal and dry-out resistant plastic ball mechanism continue to block unpleasant sewer gases even if the water seal evaporates during extended periods without condensate flow.
Designed for easy maintenance, the removable trap cartridge can be cleaned quickly without dismantling the installation, helping to reduce blockages and ensure reliable long-term performance. Manufactured in Austria, the HL 138N condensate drain trap offers a durable, professional solution for modern air conditioning systems.
