What is the spring?

Sanger ventilation is an assembly that allows a small air stream to the enclosed space as an additional source for main ventilation systems. This type of assembly can allow a constant, solid air flow or can be adjustable and can be able to close completely. Hard holes are usually built into windows and doors or skylight frames, although separate fittings are also available. The control of adjustable vents is generally achieved by means of sliding flaps, which gradually close the airflow screen. The integration of the strand into the ventilation system is beneficial because it allows constant supply of fresh air while maintaining heat and security.

Research has shown that air in most houses can be contaminated anywhere two to five times as external air. Dirt from solvents and cleaning materials, cooking, heating devices, pets, asbestos, furniture or structures and radon can turn air into a dangerous cocktail harmful to ZDthe dwarf passengers. For this reason, a reasonable air exchange in a closed environment is necessary not only for the comfort of passengers but also for their health. Unfortunately, environmental problems such as heat retention during cold weather and safety concerns often exclude the use of conventional ventilation means such as doors and windows. In these cases, the insertion offers a fair solution, allowing a constant flow of fresh air into the space and minimizing heat loss and representing no safety risks.

holes in the strands are slightly more than small holes designed as integral elements on existing building elements or as dedicated individual fittings. Integral openings are usually built into construction elements such as window and door frames or skylights. They are either solid openings or include sliding or blinds of flaps that allow settings to be closedcreatures. Many of them are relatively unobtrusive and have color coded covers that hide the holes from sight.

Reserved fittings The strand are separate elements installed through the walls of buildings. These fittings usually consist of round air pipes that pass through the wall and end the weather and insect -resistant grill and in the inside of the decorative opening. This type of strand can also be fixed or adjustable and often includes internal filters to ensure the integrity of the air that enters the space. If possible, these holes should ideally be placed in pairs, thereby located to support the flow of cross ventilation, one serving as an input point and the other as an output.
