Long throw vents are the right choice for spaces where ventilation air needs to be transported to far distances from the air outlet. One of the solutions provided by Shahrokhi Technical Institute for long air flow is jet diffuser drops.

Jet diffusers increase the throw length by reducing the cross-sectional area and increasing the air flow speed, as well as by concentrating the air flow. The most important factor in such a function is the way to change the cross-sectional area because it should be in the shortest possible length and with minimum pressure drop. Change the cross-sectional area. Shahrokhi Technical Institute's jet diffusers have an optimal cross-sectional area reduction profile for minimum valve depth and minimum pressure drop, which minimizes sound production.

The air outlet in this model of the doors has the ability to change the outlet angle by 30 degrees in all directions. The year changed the direction of the hatch based on the direction of hot wind (throwing downwards due to the rising nature of hot air) and cold wind (throwing upwards due to the descending nature of cold air). These valves are available in standard nominal diameters of 100-125-160-2-250-315-400 and... for aeration from 54 to 1440 cubic meters per hour and the ability to adjust the flow from -30 to +30, made of high quality aluminum sheet. turn around

One of the advantages of jet diffuser valves is that the screws are hidden. With the presence of an additional frame ring on these valves, when installing these valves, after opening the said ring and installing the valve with screws, the said ring is installed on the valve and covers the place of the screw under the work, which is a great help. It decorates these windows beautifully.

For the final coating of these jet diffuser valves, electrostatic furnace colors are used. After the production process, in order to remove any grease dust and other particles, the valves are acid washed, and after applying the desired undercoating (it is selected according to the type of metal and a different coating is used for each type of metal), it is sprayed on the camwire line. and the oven are placed. At this stage, the color required by the customers is sprayed on the surface and the direction valves enter the oven during the baking stage. In the baking stage, the temperature of the oven (the graph of the temperature experienced by the valve) is very important, and incomplete baking has an adverse effect on the final coating. Also, overbaking the paint causes the color to change and become matte.

On 12/16/1390, Shahrokhi Technical Institute was successful in receiving the license to use the mandatory national standard mark of air valves for the first time in Iran, and according to the decree of the National Standards Department of Iran, it started working as a partner laboratory of the Standards Department. All products produced in Shahrokhi Technical Institute, including this product, have the ability to perform various types of tests in the presence of supervisors and customers in accordance with standards 7693 and 7695 for pressure drop, throw length, flow distribution pattern and other parameters.
