Ventilation inlet PCV WYWIEWKA FI 50, no brand, model HP/W52, 50 mm diameter

PCV WYWIEWKA FI 50 is a compact 50 mm diameter ventilation inlet designed for mounting in ducts or walls. Supplied as model HP/W52 without a brand name, it creates a simple terminal for controlled fresh air entry or to balance exhaust in small ventilation systems. The unit is suitable for residential and small commercial installations where limited space or discrete ventilation points are required, such as bathrooms, kitchens, utility rooms and localized supply or exhaust positions.

Advantages

The ventilation inlet offers a small footprint and straightforward installation into round ducts or wall openings, providing reliable air passage with minimal visual impact. Its PVC construction resists moisture and common household conditions, enabling use in humid rooms. The standardized 50 mm diameter allows compatibility with typical small-diameter ventilation ducts and fittings, simplifying integration into existing systems.

Suitable for

• Small residential ventilation ducts and wall terminals
• Bathroom and kitchen exhaust or fresh air intake points
• Utility rooms, laundry areas and small service spaces
• Localized supply or exhaust connections in renovation projects

Key specifications

• Material: PVC (polyvinyl chloride)
• Nominal diameter: 50 mm
• Mounting: duct or wall installation for round openings
• Typical application: small ventilation systems, supply or exhaust terminals
• Resistance: suitable for humid indoor environments

How to use

Prepare a round opening of suitable diameter in the duct or wall and ensure the surrounding structure is clean and stable. Insert the inlet into the opening until it seats firmly and secure it using appropriate fasteners or sealants suitable for PVC-to-wall or PVC-to-duct joints. Connect the inlet to the ventilation ductwork with compatible 50 mm fittings or flexible ducting to ensure an airtight connection. Verify airflow direction and adjust any upstream fans or dampers to achieve the desired balance between supply and exhaust.

Usage recommendations

For long-term performance, inspect the inlet periodically for dust buildup and clean with a soft brush or damp cloth. Avoid exposure to high temperatures or direct flame. When installing in wet areas, use appropriate sealing and, if required, supplementary splash protection. Match the inlet with ducts and accessories designed for 50 mm diameter to maintain airflow efficiency and system balance.
