Product information

Features and benefits

Wide range of applications - Meteor MLS is classed as a dual purpose ventilator, providing both day to day and smoke control ventilation. A polycarbonate version allows the entry of natural daylight, and an aluminium infill panel is available, with the option of additional acoustic attenuation. Pneumatic or electric linear drives are available.

High performance - Meteor MLS has high aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire.

Acoustic performance – Meteor MLS offers the option of a reduced noise panel with a performance of up to 33 dB R’w.

Thermal performance – As an option, the base of Meteor MLS can be thermally broken to reduce air leakage and increase insulation.

Proven performance - Meteor MLS has been exhaustively tested and certified to EN 12101-2: 2003 in accredited third party test laboratories and is CE marked.

Easy to install - Meteor MLS may be installed into glazing, onto a curb or into sheeting. It has a wide range of base profiles to suit most glazing, sheeting or curb types.

Durable - Meteor MLS is manufactured from tough, corrosion resistant aluminium with stainless steel fixings.

Quality of manufacture - Meteor MLS is manufactured under the ISO 9000 quality standard.
