Natural flap ventilators providing both smoke and day-to-day ventilation. It allows extract ventilation for most kinds of industrial buildings and is usually installed on building rooftops.

Apollo ATI includes weathered ventilation via longitudinal side flaps.

Features and benefits:

Wide range of applications: Both models are classed as dual-purpose ventilators, providing day-to-day and smoke control ventilation, and generally installed onto roofs providing high-level extract. Polycarbonate versions allow the entry of natural daylight. Manual, pneumatic or electric controls are available.
Efficient and weather-resistant: Aerodynamically efficient. The sealing system consists of EPDM profiles which keep air leakage down to a minimum.
Weathered ventilation (Apollo ATI only): Longitudinal flaps and deflectors set within a wind baffle provide aerodynamic ventilation when the weather is wet.
Easy to install: Delivered fully assembled to site. Wide range of base profiles to suit most sheeting, curb or glazing applications.
Durable: Manufactured from tough, corrosion-resistant aluminium with stainless steel hinges. Tested and certified as fall-through-proof in 300J and 1200J tests by an external test house. Manufactured under the ISO 9001 quality and ISO 14001 environmental management standards.
Certified performance: Has been exhaustively tested and certified to EN 12101-2: 2003 in accredited third party test laboratories and is CE marked.
High thermal performance: Highly insulated and air tight, meeting or exceeding current energy savings regulations. Good U-value, as low as 1.5 W/m²K.
High acoustic performance: With the aluminium lidded version, a sound reduction of up to 28/ 26 dB Rw (Apollo/ Apollo ATI) may be achieved.
Manufactured under the ISO 9001 quality standard. Each unit is given a functional test before dispatch.
Low in weight.
