Introducing Pascal Damper 150: A Revolutionary Solution for High-Performance Homes

In recent years, the push for decarbonization has led to a significant enhancement in residential energy efficiency, resulting in an increasing number of high airtight houses, characterized by a C-value of less than 1.0 cm²/m². However, while the airtightness of homes improves, the use of exhaust systems like range hoods and gas clothes dryers has brought to light the concerns of excessive negative pressure within these spaces.

Understanding the Issue of Negative Pressure

As the airtightness of homes increases, a pressing challenge emerges when operating equipment that expels large volumes of air. This can lead to a state of excessive negative pressure indoors, resulting in several discomforts such as:

• - Difficulty in opening entrance doors
• - Ingress of odors from drainage traps
• - Diminished efficiency of heat exchange ventilation due to disrupted intake and exhaust balance

To mitigate these issues and maximize the potential of high-performance, airtight homes, NJKK released the Pascal Damper 150 on May 11, 2026.

Features of the Pascal Damper 150

The Pascal Damper 150 is designed to alleviate negative pressure problems while complementing various home ventilation systems. Unlike previous models that opened at 7Pa, the Pascal Damper 150 has adjusted its operational pressure to 10Pa, which prevents unintended opening during regular 24-hour ventilation cycles in highly airtight homes. This product represents an evolutionary step to meet market demands by ensuring precise operational timing and stable air supply.

Three Key Contributions to Enhance Home Comfort

1. The Ideal Partner for Gas Clothes Dryers
With the rise of dual-income households, the use of gas clothes dryers has become commonplace. These devices require a substantial volume of makeup air to function effectively. Inadequate air supply can lead to reduced drying and combustion efficiency, acting as an unseen obstacle in household chores. By incorporating the Pascal Damper 150, homes can provide necessary air to these appliances, thereby enhancing household efficiency and overall comfort.

2. Completing the Hot Exchange Ventilation Puzzle
Many homeowners have opted for heat exchange ventilation systems to ensure comfort and energy savings. However, a drop in air balance caused by range hood use can hinder the performance of these systems. The Pascal Damper 150 automatically adjusts air supply based on pressure differences, thereby preserving the investment in heat exchange ventilation and ensuring an optimized indoor thermal environment.

3. Normalizing Third-Type Ventilation While Reducing Negative Pressure
Common signs of excessive negative pressure, particularly in high-performance homes, include heavy entrance doors and the backflow of odors into living spaces. The Pascal Damper 150 proactively senses and responds to pressure levels, initiating airflow before occupants notice discomfort, thereby creating a stress-free living environment for all family members.

Product Highlights

• - No Power Required, Automatic Airflow Adjustment: Automatically regulates the opening size of the damper based on the pressure difference between indoor and outdoor environments, starting to open at around 10Pa, half-open at 18Pa, and fully open at 30Pa.
• - Durable and Maintenance-Friendly: Made with weather-resistant ASA resin, which minimizes discoloration over time. The built-in pollen filter is designed to conceal screw holes, balancing functionality with aesthetic cleanliness.
• - Unified Design with Existing Products: The Pascal Damper 150 aligns with NJKK’s existing products like the Square Flow 150, allowing for cohesive design and flexible application in home ventilation setups.
