We have been the first to market a number of technical innovations and improvements.We hold a series of patents (designated below as PP = “Prihoda Patent”)and in many of the cases described below we are still the only firm to supply this equipment.
NEGATIVE PRESSURE (EXTRACT) DUCTING (PP)
Our patented tensioning structure enables us to manufacture rectangular-sectionducts which canalso be used forextraction.
Directional holes with a diameter less than the thickness of the fabric are a design patented by Příhoda s.r.o. They provide a number of advantages when used for surface air supply at low speed.
Flat diffusers into false ceilings do not have to be made of sheet metal; our SquAireTex range is a fully-fledged alternative.
Ultrasound-connected nozzles 20 to 40 mm in diameter are a great way of achieving greater flow range. Compared to plastic nozzles they are significantly more fire resistant and stay on the duct better.
Used to straighten out an inclined outflow from perforated fabric and prevent air flow from spreading along the ducts.
FABRIC SHUTTER (PP)
The first fabric shutter on the market is used to temporarily close off a branch or part of a duct.
INSULATED AND DOUBLE DUCTS, NOISE DAMPERS (PP)
To prevent condensation from forming on the surface of the duct and to cut heat or cooling loss, we manufacture ducts that are either insulated or double with an intermediate layer of air. Insulated ducts are also effective noise dampers.
LANTERN WITH MEMBRANE (PP)
This space-saving large volume diffuser enables air to be supplied horizontally or vertically down depending on the position of the internal membrane.
FABRIC COLOUR MODIFICATIONS
Our own colouring and printing technology enables us to supply fabric in any colour or to print it with the graphics of your choice, all by the standard delivery deadline.
LUCENTAIR - A combination of ventilation with lighting
LucentAir combines a common fabric with a special one, which allows 80 % of light to pass through it and alows high quality lighting. The light source is usually an LED strip (which is not supplied) fixed to an aluminium profile.
