Common Mistakes in the Installation of Fire Dampers Equipped with Actuators

The incorrect installation of actuators and fire dampers often leads to defects that are not covered by service warranties. Improper positioning of the products or installing them in unsuitable locations can lead to device failures, which are not a result of poor manufacturing but installation errors. How should the correct installation of fire dampers be carried out? Discover the mistakes to avoid.

Hospital air. Air purification and pressure gradient in hospital rooms

It is required that proper air purity is maintained in hospital rooms. Such rooms are classified by allowable impurities level. Appropriate cleanliness class is maintained by the use of filters in air handling units, ducts or even air supply diffusers themselves, as well as by pressure gradient relative to adjacent rooms.

A few words about the selection program for diffusers

People have less and less time to carry out their tasks, both in their private life and their professional life. Developers are building faster than ever, and designers have less and less time to create a project. To perform the same work, but maintain quality, it’s essential to have properly-prepared work materials. In our industry, these are not only product data sheets for use on the project or in the building, but also selection programs.

Pressure Differential System — Advantages, Standards, Functioning

Every year, all over the world, modern tall buildings of various purposes are being constructed. For each of them — according to strict regulations — it is necessary to ensure the safety of users in case of fire. In order to achieve this goal some reliable and highly effective systems may be used. The systems make it possible to control the spread of smoke and heat appropriately. It is worth noticing that in most cases the most dangerous mortal threat for people during fire in such buildings is not the fire itself but the smoke and toxic gases being created during combustion process.

How to Select and When to Use Smoke Dampers

Smoke dampers are multifunctional devices that can improve safety in case of fire. But this is not their only role. Manufacturers offer smoke dampers in various shapes and sizes. Among them there are square, rectangular, and round dampers. Lately, louvre-like devices have also become more and more popular. The latter option has two main advantages: it is easy to open and offers low resistance against the air stream.

Fire ventilation systems for enclosed garages

Limited space for investment has made constructing underground garages as part of buildings increasingly popular in our country. In particular, this is true for large city centres, where the number of parking spots in the streets is smaller than the number of drivers looking for a parking space. As a result underground and multi-storey car parks are becoming more popular.
