Fresh Air Vent Fresh TL80DE dBs NEW
Fresh
Fresh Air Vent Fresh TL80DE dBs NEW
Art. no.: 9302640
Wall vent with a very discreet design. The front can be wallpapered and painted over. The vent is equipped with strong condensation insulation, over-ventilation protection, storm protection, and a filter. The storm protection prevents energy loss due to wind impact. The flow is regulated with the front, which has a mechanism for changing the opening angle. The front opens at the top and directs the air upwards, providing a comfortable distribution pattern even with underfloor heating.

Sound-reducing: The sound-absorbing wall duct consists of a sound-absorbing pipe instead of a standard wall pipe. The sound-absorbing pipe is easy to cut to the correct length with a utility knife. Standard pipe length is 360 mm.

Internal vent part: The internal vent part has strong condensation insulation, a filter, and a front that tilts up at the top to adjust the flow. The filter is mounted in a filter cassette, which is also equipped with protection against any incoming water. The front has four opening positions to vary the flow. The distribution pattern is carefully developed to suit underfloor heating systems; the vent directs the air upwards and to the sides. The mixing of room air is very efficient; just a few decimeters from the unit, the strongly cooled air has reached a comfortable temperature.

Installation/placement: The vent should be placed high up on the wall; if there is a radiator, it should ideally be placed above it. This placement utilizes the convection current and achieves the best comfort. The vent is excellent for use with underfloor heating as it is designed for this purpose.

Handling/maintenance: To ensure good air quality and maintained flow, the filter should be cleaned/replaced 1-2 times a year. The standard filter is washable; use a mild soap solution. Pollen and environmental filters should be replaced with new ones. The filter is mounted in a filter cassette behind the front, which is easily removed by releasing the front from the lower attachments and then lifting it up. The filter cassette is pulled straight out from the vent chassis.

Accessories: A complete accessory series is available for the vent for additional flexibility.
