Displacement ventilation hoses
A good indoor climate requires unobstructed air flow
Micro-perforations in the material covering the output openings allow air to be blown slowly and steadily into the room. This curtain of air provides what is known as a piston effect, air containing harmful substances flow towards the extraction inlet.
A good indoor climate requires: clean air.
The filters is made up of extremely fine synthetic fibres together to form wedge-shaped filter pockets, with end frames made of galvanised steel or plastic. The individual pockets are securely fastened to the frame and sealed with a corrosion-proof plastic gasket.
A good indoor climate requires: no noise disturbance
Components such as fans produce unwanted noise. To keep the noise level at an acceptable level, noise insulators are built into the ventilation system as required. Sufficient insulation also keeps aerodynamic drag at a minimum. Using aerodynamically profiled splitter frames reduces pressure loss and therefore operational costs. The surface is covered with material made of biodegradable mineral wool that will not rot. The noise insulators are coated with moisture-resistand glass silk that is resistant to wear and tear an covered with galvanized steel
A good indoor climate requires: comfort
Cold outside air can cause drafts must be heated before it is introduced into the gun range. Two lamellar heat exchangers are used to heat cold air. Air is heated using heat from hot water or glycol via an intricate system of pipes fitted with a number of fins.
The best in ventilation technology: low power consumption
The demands for energy are ever increasing. Our high-performance fans have been especially developed for their use in modern ventilation and air-conditioning systems and are perfect for moving air and aggressive (lightly corrosive or acidic) gases and fumes. We are constantly developing and upgrading the rotor technology resulting in low power consumption, low costs and low noise.
