Fine filter bag for cistern inlet – Clean rainwater even during heavy rain
Maximum filtration without clogging: The sustainable solution
Filtering rainwater is becoming increasingly important due to the growing frequency of heavy rainfall events. The WINKLER fine filter bag for cistern inlets was specially developed to reliably retain even the finest particles , sediments, and contaminants from the incoming water – without obstructing the flow .
The secret lies in the material: While conventional felt filter bags often clog up quickly, our special polyester composite material guarantees the best filtration results with consistently high water permeability . This ensures your cistern remains functional even during heavy rain.
Your advantages for cisterns and building technology
A professional cistern filter protects your system sustainably and improves the quality of your tap water :
- Protection against sludge buildup: Retains particles down to 70 µm and prevents sludge deposits in the tank.
- Durable technology: Increases the lifespan of pumps, pipes and irrigation nozzles .
- Optimal water quality: Improves the purity of rainwater for garden irrigation, household and commercial use.
- High safety: Six circumferential, 25 mm wide straps keep the bag securely in position even under heavy water loads.
