The impact-resistant innovation with high-performance
membrane.
The clever, compact and innovative solution prevents pressure differences, temperature fluctuations and condensation in electrical and electronic housings. AGRO’s new, innovative pressure balance element facilitates quick and reliable air exchange and ensures the housing stays dry inside.

Whether traffic control and signalling technology, street lighting, railway vehicles, distributor housings for energy distribution, or solar energy systems: they must all withstand wind and weather, heat and rain. The same applies to their electronics and electrics. Air pressure, temperature and humidity are constantly changing. Sealed housings are never completely sealed.
Many electrotechnical housings are watertight and dust-tight (IP 68) but not gas-tight. Changing temperatures can thus produce a pressure difference, causing air exchange. This leads to condensation, which can result in corrosion and defects/malfunctions. This is prevented by installing AGRO pressure balance elements.
AGRO has developed a new, innovative pressure balance element of A4 stainless steel (EN 1.4404 / AISI 316L) for use in stainless housings (patent pending), which is unsurpassed in terms of robustness and offers the highest impact resistance in accordance with IEC EN 62262, Class IK10.

High-quality materials combined with innovative design
A high-performance membrane ensures rapid, reliable air exchange with outstanding flow rates. It is made of PTFE (polyterafluoroethylene) and has pores that are bigger than water vapour molecules but smaller than water droplets. The water- and oil-repellent membrane offers a very high degree of protection: IP66 / IP68 (0.5bar/1h) / IP69 / IP6K9K. The wide temperature range, from -40 °C to +150 °C, is another highlight of the new pressure balance element. The product features an M12x1.5 entry thread. The membrane is RoHS- and REACH-compliant, and free of PFOA and PFOS.
