In general, all mechanical devices that are installed under the false ceiling of the building need access and inspection doors for periodic services or repairs. Therefore, inspection doors are used to access these equipments. The aluminum fan coil inspection door is used for ventilation devices such as fan coils and split ducts.

If the return air suction of these devices is through the return channel, these inspection doors do not need a grill or groove, but if the return air suction is from under the device, the inspection door needs a grill or groove. For these cases, Shahrokhi Technical Institute offers different solutions in different models.

Fan coil inspection doors are divided into two general categories: Siemens locks and hinges and weighted fan coil inspection doors. In lock and hinge models, grills are not considered by default, but the ability to add mesh grills, linear valves and There is an egg basket valve on them. Weight models are also divided into two products, single groove and double groove, which are selected according to the ventilation rate of the device and decorative taste. In these models, the door is separate from the valve frame and the door is weighted on the frame.

Single-slot and double-slot vent under the fan coil are also produced by combining two weight models and lock and hinge. This model is used when the distance from the ceiling to the machine is not enough and it is not possible to separate the weighing inspection door. Therefore, the beauty of single-slot and double-slot inspection doors is achieved, and also the limitation of the space above the inspection door to the machine is eliminated.
Final cover and valve installation under the fan coil

Like most of the valves produced in this collection, an automatic screw is used to install this product, and instead of a screw (treasure), it is created before applying the color coating on the valve frame. It is better to install this valve on a wooden or metal frame to be sure, and if the valve is installed directly on plaster, there is a possibility of the valve loosening over time.

In order to install this valve on false walls with dry materials (Kenaf, etc.), it must be ensured that special false ceiling profiles are used around the opening of the valve for strength and reliable connection of the valve to the wall.

For the final coating of these 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 furnace are placed. At this stage, the color required by the customers is sprayed on the surface and the direction valves enter the furnace during the firing stage. It has an adverse effect on the final coating. Also, overcooking the paint changes the color shade and makes it 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.
