Weltico pre-filter bag Weltibag P7 500 µ

Weltico pre-filter bag Weltibag P7 500 µ

The Weltico pre-filter bag Weltibag P7 500 µ is a reusable skimmer pre-filter designed to capture coarse debris before it reaches the main pool filter. With a filtration fineness of 500 microns, it retains hair, insects, small leaves and other visible particles in the skimmer basket, helping to keep the sand or cartridge filter cleaner and to maintain a stable, efficient water flow.

500 micron pre-filtration for everyday use

The 500 micron mesh of the Weltico pre-filter bag Weltibag P7 500 µ is ideal for daily pool operation. It intercepts the bulk of floating contaminants on the water surface while still allowing sufficient flow towards the filtration system. By stopping debris directly in the skimmer, the pre-filter reduces the load on the main filter and can extend the intervals between backwashing or cartridge cleaning.

This level of pre-filtration is particularly useful in outdoor pools surrounded by vegetation or exposed to frequent bather loads, where leaves, pollen and cosmetics quickly accumulate at the surface.

Reusable bag for lower running costs

The Weltico pre-filter bag Weltibag P7 500 µ is made from a durable, washable fabric that can be reused many times. Instead of consuming disposable skimmer socks, you simply remove the bag from the basket, empty the collected debris and rinse it under a tap or with a garden hose. Once clean, the bag can be reinstalled immediately, offering a cost effective and environmentally friendly solution.

• Reusable construction reduces waste and consumable costs.
• Quick cleaning by emptying and rinsing the fabric.
• Helps keep both the skimmer basket and main filter cleaner for longer.

Designed for compatible Weltico skimmer baskets

This Weltibag P7 500 µ model is shaped to fit compatible Weltico skimmer baskets of the corresponding size. The flexible textile adapts to the internal contour of the basket and provides a large effective filtration surface, so water can pass through freely as long as the bag is emptied regularly.

• Installed directly inside the skimmer basket in a few seconds.
• Collects surface debris before it reaches the filter tank.
• Supports steady circulation when maintained correctly.

Support for clearer water and easier maintenance

By trapping larger contaminants at the skimmer level, the Weltico pre-filter bag Weltibag P7 500 µ contributes to clearer water and more efficient treatment. Less organic matter reaches the filter media, which can help reduce odours, staining and cloudiness caused by accumulated debris. At the same time, weekly maintenance becomes easier because most visible dirt is removed in one operation when you empty and rinse the skimmer basket.
