Atmos® Air Dual
The Atmos® Air Dual units are loft mounted Multiple Input Ventilation (MIV®) systems, which are designed to supply air from two separate locations, this helps solve ventilation issues in properties with irregular shaped hallways or where air is required to be supplied into a remote habitable room. The constant flow of filtered air will dilute, displace and replace moisture-laden air within the property. This helps to control humidity levels, so that condensation, mould and other indoor air contaminants are significantly reduced helping to create a healthy indoor environment. All Atmos® units come fitted with an intelligent 500W heater to help temper incoming air in the colder months, as well as a data logger to provide landlords and homeowners with important information about the amount of time the unit has been running. Atmos® Air Dual units have two operating modes that help prevent overheating making it a great solution for properties affected by this. The units have an AirSource Bypass and an Intelligent Summer Bypass. The AirSource Bypass is activated when temperatures in the loft space rise above 25°C, the unit swaps to source cooler air directly from atmosphere via the duct run. If the outdoor temperature continues to rise above 28°C, the Intelligent Summer Bypass will temporarily shut the unit down to stop hot air being supplied into the property. When temperatures fall, the unit will start to run again.

10-Year Warranty
Peace of mind for all customers with this extended warranty period. If you encounter any problems, envirovent® will either fix or replace the unit within the 10-year period.
AirSource Bypass and Intelligent Summer Bypass Modes
The AirSource Bypass swaps the air supply to come directly from outside when temperatures rise above 25°C to bring in cooler air. The Intelligent Summer Bypass will temporarily switch the unit off when temperatures outside rise above 28°C. These modes help to prevent overheating within the property.
Different Control Options Available
Atmos® Air has 3 different models, and each are controlled differently. ATL-AIR unit is controlled via the unit. ATL-AIR-W is controlled using a wireless controller and the ATL-AIR-A unit is controlled on any smartphone using the Myenvirovent App.
Intelligent Comfort Heater as Standard
This ensures that the air is not only filtered upon entry of the property, but it is also tempered to a comfortable temperature.
0-10V Input and Compatible with AirSens®
AirSens® or any 0-10V environmental sensor can be used to create a demand control ventilation unit, this will proportionally increase the units speed depending on the measured concentrations within the property.
Variable Speed Control
Atmos® airflows can be selected and adjustred meet the exact requirements for the property it is installed in. There are 4 pre-set speeds that can be selected or the airflow can be variably controlled.
Professional Installations
Every system is supplied and professionally fitted, giving you complete peace of mind the installation has been completed to the highest standard by envirovent® or an envirovent® approved specialist engineer.
Datalogging as Standard
All Atmos® units come with integral datalogging. This tracks exactly how many hours the unit has been running, from the moment it was installeed. This is particularly helpful for landlords who may have disputes with tenants.

ATMOS® Range
Frequently Asked Questions
The ATMOS® range of units provides fresh, filtered air into a property from a central location, which is often a landing or central space.
The units come with a pulse heater to temper the air, which is then positively pushed around the property, replacing any stale, moist air with renewed air. This circular process continues, helping to reduce condensation and mould in the property.
The ATMOS® range of units includes units suitable for loft mounting, either ducted to atmosphere for Air Source, Inline or multiple input, or for wall mounting.
There are units with hard-wired, wireless or app controls also available.
The ATMOS® is to be installed in a loft space, the ATMOS® Wall is for properties with a low apex, unsuitable roof or for an apartment.
The ATMOS® range of units is available for supply and fit only by Envirovent and carries a 10-year warranty.
The ATMOS® Wall is also available for supply and fit, again carrying a 10-year warranty, or a 5-year warranty for supply only.
All ATMOS® and ATMOS® Wall products come with a filter as standard, with a minimum of ISO Coarse 65%.
Although the ATMOS® and ATMOS® Wall products come with a pulse heater, this is used to temper the air should the temperature outside drop and is not a form of heating to be used within a property.
If the temperature in the property is in excess of 25°C, most of Envirovent ATMOS and ATMOS Wall units will also go into sleep mode to prevent excessively hot air entering the property before switching back on when the temperature drops. If the unit is ducted to the atmosphere, the unit will continue to run all year round.
An ATMOS® can be installed in a three-storey property providing that the layout allows for this. However, there are requirements regarding protected areas in a property with a height of 4.5m or above, which will need to be taken into account.
A wireless ATMOS® with a specialist metal diffuser will be required for such a scenario. Please get in touch with our Technical Department on 01423 810810 option 5 to discuss fire stopping requirements further.
ATMOS® and ATMOS® Wall units will ventilate all rooms directly linked to the unit. If the unit is located in a central position, this should cover the vast majority of rooms.
However, if you have to walk to one room to get to another (i.e. an en-suite, or walking through a living space to a kitchen or other wet room not connected to the hallway or central space) then an additional continuous ventilation option is required in that remote wet room, such as a d-MEV.
ATMOS® and ATMOS® Wall units generally run all of the time, with the exception of the units that go into sleep mode during periods of hot weather.
These are not designed to be obtrusive and provide fresh, filtered air into the property.
