Ventilation Plugs
Membrane-equipped models also allow moisture vapour to escape, helping reduce condensation. Choose the appropriate plug for your enclosure’s mounting requirements, operating conditions and required level of protection.
Frequently asked questions about Ventilation Plugs
What does an enclosure ventilation plug do?
It compensates for pressure differences between the inside and outside of an enclosure caused by temperature changes.
Can ventilation plugs help reduce condensation?
Yes. STEGO’s membrane-equipped pressure compensation devices allow moisture vapour to escape, helping reduce condensation inside the enclosure.
Do ventilation plugs require power?
No. These pressure compensation devices operate passively without an electrical supply.
What IP rating do STEGO ventilation plugs offer?
The rating depends on the model. The DA 084 offers IP55 when installed vertically; other models offer different protection ratings. Always check the individual product specification and installation instructions.
How do I choose the correct ventilation plug?
Check the required protection rating, mounting size, enclosure material, operating temperature and installation position against the product datasheet.
Can a ventilation plug replace a filter fan?
A ventilation plug is designed for pressure compensation. Where your enclosure needs active cooling, assess its cooling requirements separately.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks
Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure. The kind of faults that are frustrating to trace and expensive to fix.
Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
