When safety is a priority

Airocle’s Y Series is an excellent natural pressure-relief ventilation solution in situations where fast ventilation may be needed.

Our experienced team of engineers have specifically designed the Y Series vents to be simple, efficient and fail-safe.

Featuring an integrated counterweight-activated blade system, the Y Series wall vents provide rapid, reliable and effective relief from over-pressurisation from within a building.

When the ventilator experiences a rise in pressure, it responds ultra-fast, allowing for the release of expanding heated gases and optimising the safety of your structure. The louvres re-close after operation.

Applications & Uses

Ideal for volatile operating environments

The Y Series is particularly useful for volatile operating environments where fast and effective ventilation of unexpected blast and pressure damage minimisation are required.

Building types Y Series vents are suited include:

  • Workshops & Warehousing
  • Chemical Storage
  • Electricity Sub-Stations
  • Pyrotechnic Storage
  • Chemical Processing
  • Ammunition Stores
  • Telephone Exchanges
  • Research & Industrial Laboratories

Key Benefits

Effective Pressure Relief

Purposefully directed pressure relief ensures optimal performance in volatile working environments, safeguarding against potentially explosive atmospheres.

Additional Roof Option

Choose between options of both roof and/or wall mounted pressure relief, with Y Series. You can find more information on the Roof Mounted series, here.


Our expert engineers have designed Y Series ventilators to be weather-tight and storm proof.

Efficient Design 

Secure, high quality and reliable operating components are available in customisable materials. Coupled with ‘green,’ high quality, natural design principles, you can be sure of an economical and aesthetically-pleasing result.

Makes ‘Green’ Building Easier
