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.

- Zero corrosion risk: This fan does not come into contact with chlorine or pool humidity, because it works exclusively with outdoor air.
- Choice: A standard high-quality inline duct fan is sufficient for this position without the need for special chemical resistance.
- Filtration barrier: Air from the pool first passes through filter fabric, which mechanically captures aerosol (microdroplets of water with concentrated chlorine).
- Condensation cleaning: In the heat recovery exchanger, the air cools down and the moisture condenses. This water binds gaseous chlorine to itself and safely drains it away into the wastewater system.
- Result: The fan placed after the RECUBOX works with significantly “cleaned” air, which protects its motor and bearings.
What fans should be selected for pool ventilation?
The selection of fans for pool areas is critical due to the high humidity and the presence of aggressive chlorine. However, when using the RECUBOX® X-POOL unit, the design of the unit significantly changes the fan resistance requirements in your favor.
1. Fan for supply air (fresh air)
In this part of the system, the situation is the simplest. The supply fan draws in clean outdoor air and pushes it through the heat recovery exchanger into the pool hall.
2. Fan for exhaust air (waste air)
Thanks to the unique integration with the RECUBOX® X-POOL unit, the exhaust fan is protected in a way that significantly extends its service life:
Recommendations for installation and maintenance
Key rule: RECUBOX® as the lowest point of the system
For proper operation, the RECUBOX® unit must be installed at the lowest point of the air handling route. Only then can the ducting naturally drain all aggressive condensate with chlorine towards the unit and subsequently into the drain. This prevents moisture from accumulating near the fans or at critical duct joints.
| Duct material | For the exhaust branch, we recommend exclusively plastic (PVC/PP) or stainless steel ducting. Aluminum ducting is subject to rapid corrosion. |
| Fan type | We recommend choosing fans in an all-plastic design with protection rating at least IP44. |
| Filter maintenance | Regular inspection of the filter fabric is essential in pools to maintain the cleanliness of the exchanger as well as fan protection. |
Our professional view: The combination of the durable RECUBOX® X-POOL design and suitably selected plastic fans represents the technically cleanest solution for modern pools. This configuration saves costs because it eliminates the need for extremely expensive industrial fans intended for the chemical industry.
Note: The above information represents the manufacturer’s recommended technical practice for extending component service life. The final fan selection should always correspond to the HVAC design and the expected concentration of chemical substances in the specific installation.
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.
