ResiX X-PP - Ø100–630 mm - Chemically resistant polypropylene filter box
Chemically resistant pocket filter box resiX X-PP made of 100% polypropylene. Filtration classes G3–M5, connections Ø100–630 mm. Also available in PE or PVC depending on the air chemistry.
ResiX X-PP is a pocket filter box designed for industrial and laboratory applications where chemical resistance and reliable filtration are key. The entire body is made of 100% polypropylene (PP) as standard, which offers maximum protection against aggressive chemicals, corrosion and moisture.
The filter box is equipped with Syntex pocket filters with efficiency classes G3–M5 , which ensure effective dust and dirt capture with low pressure loss and long service life. Standardly manufactured with connection diameters Ø100–630 mm or in a square design according to customer specifications.
The price and stock are valid for the DN 400 filter box with dimensions of 520x520x500 mm with a Syntex ISO ePM10 50 (M5) 500x500x360mm 5-pocket pocket filter.
If you provide us with data on the required air flow (m³/h) and the connection shape, we will suggest the most efficient option and calculate the best possible solution with the appropriate box size.

What ducting should be used for pool ventilation?
The choice of ductwork material is just as important for a swimming pool as the heat recovery unit itself. An aggressive environment with chlorine content combined with high humidity can destroy improperly selected ducting within a few months.
Why avoid aluminum and cheap “flex” hoses?
Commonly used aluminum flexible ducts (so-called Alu-flexi, Sono-flexi) are completely unsuitable for pool environments. Chlorine vapors cause rapid oxidation of aluminum, which appears as white powder formation followed by perforation of the duct wall.
Warning about leaks: Once corrosion occurs, the system loses pressure balance, humidity in the building structure increases, and mold may develop around leaking duct sections.
Recommended materials for RECUBOX® X-POOL
For long-term reliable operation of pool ventilation, we recommend using materials that naturally resist corrosion:
| Plastic ducting (PVC / PP) | Ideal choice for pools. Smooth plastic ducts are 100% resistant to chlorine and moisture and have minimal pressure losses. |
| Stainless steel ducting | Premium solution with extreme mechanical durability. Suitable for exposed design ducting in interior spaces. |
| Insulated EPE ducting | Excellent for routes passing through unheated areas. Foamed polyethylene is non-absorbent and chemically resistant. |
Important: Slope and condensate drainage
Gravity works for you:
All horizontal duct runs must be sloped towards the RECUBOX® unit (minimum slope 1–2%). Since the RECUBOX® is installed at the lowest point, all condensate containing chlorine compounds flows smoothly into the exchanger and directly into the drain. This prevents the formation of “pockets” of standing water inside the ductwork.
Practical tip: If flexible ducting must be used in certain places (e.g. for connections), always use plastic flexible hoses or hoses with a chemically resistant inner layer. This will help you avoid costly repairs in ceiling spaces in the future.
Note: Proper selection of duct material is crucial to maintain the 12-year warranty on the airtightness of the RECUBOX® unit casing. Inappropriate ducting may negatively affect the hygiene of the entire system.
