In modern industrial and automotive systems, breather valves and vent membranes play a critical role in ensuring safety, performance, and longevity of equipment. From battery enclosures to electronic devices, these components provide protection against environmental hazards while maintaining optimal functionality. Our range includes polyethyleen breather valves, corrosieve dampen breather valves, polyvinylchloride breather valves, and polypropyleen breather valves, designed to meet diverse industry requirements.

Our breather valves and vent membranes are engineered to control pressure, prevent contamination, and allow safe release of gases in sealed systems. They are widely used in batteries, industrial machinery, automotive systems, and outdoor equipment. Key products include:
Polyethyleen Breather Valves: Lightweight, durable, and chemical-resistant, ideal for general industrial and battery applications.
Corrosieve Dampen Breather Valves: Designed to withstand harsh chemical environments, ensuring long-term reliability.
Polyvinylchloride Breather Valves: Cost-effective and resistant to a wide range of environmental factors.
Polypropyleen Breather Valves: High-temperature and chemical-resistant valves suitable for industrial machinery and automotive systems.
Automotive membrane vent solutions are essential for controlling pressure in fuel systems, transmissions, and electronic components. They help prevent moisture ingress and corrosion, maintaining optimal performance under harsh conditions.
Our breathers for battery enclosures and plastic battery safety valves ensure safe gas release during charging or discharging cycles. These solutions prevent overpressure, reduce risk of explosion, and protect battery life. Some valves are designed as explosion valves for high-safety applications in lithium-ion batteries and other energy storage systems.
Waterproof acoustic vent and waterproof vent membrane products combine environmental protection with noise control. These membranes are ideal for electronic enclosures, outdoor monitoring equipment, and industrial devices that require both ingress protection and acoustic transparency.
Durability and Chemical Resistance: Materials such as polyethylene, polypropylene, and PVC ensure long-term performance in corrosive and industrial environments.
Environmental Protection: Waterproof and dustproof designs prevent moisture, dust, and other contaminants from entering sensitive systems.
Pressure Regulation: Breather valves maintain safe pressure levels, preventing equipment damage or failure.
Explosion Safety: Special explosion valves in battery and chemical applications reduce risk of catastrophic failures.
Versatile Applications: Suitable for automotive, industrial, electronics, energy storage, and outdoor equipment.
Ease of Integration: Flexible designs and sizes allow seamless integration into new or existing systems.
