Review: Fonctionnent toujours très bien depuis 4 ans. J'ai pris du rechange pour ne pas être en galère en pleine canicule si jamais 1 venait à me lacher... Déportées dans les combles et sur les tapis antivibration je ne les entends plus du tout contrairement à l'installation dans les goulottes ou même fixées sur le support antivibation sur une poutre que l'on entendait quand même, là avec un bon tapis antibruit/antiviration, plus un bruit pour dormir au frais. ## Features - Condensation control and drain: Sauermann si-30 condensate pump, Manufacturer: Sauermann ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008M67DTU | | ASIN | B008M67DTU | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #236,932 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #41 in HVAC Condensate Pumps | | Color | Grey | | Customer Reviews | 4.5 4.5 out of 5 stars (239) | | Customer reviews | 4.5 4.5 out of 5 stars (239) | | Date First Available | 28 October 2013 | | Date First Available | 28 October 2013 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 381 g | | Item model number | AS06032 | | Item model number | AS06032 | | Manufacturer | Sauermann | | Manufacturer | Sauermann | | Part number | SI-30 | | Product Dimensions | 16.51 x 10.92 x 10.92 cm; 381.02 g | | Product Dimensions | 16.51 x 10.92 x 10.92 cm; 381.02 g | ## Images ![Sauermann Si-30 Condensate Pump - Image 1](https://m.media-amazon.com/images/I/31ua6J3A2fL.jpg) ![Sauermann Si-30 Condensate Pump - Image 2](https://m.media-amazon.com/images/I/41ZCh7JhjwL.jpg) ![Sauermann Si-30 Condensate Pump - Image 3](https://m.media-amazon.com/images/I/41syUZCYZhL.jpg) ![Sauermann Si-30 Condensate Pump - Image 4](https://m.media-amazon.com/images/I/41x8VALW9kL.jpg) ![Sauermann Si-30 Condensate Pump - Image 5](https://m.media-amazon.com/images/I/81MDNHadV-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***A on 6 October 2019* Todo perfecto.
