Parking Ventilation Damper - For Exhaust System F300

Damper is a device for controlling and changing the flow of air passing through the duct, which is divided into different types, one of which is the double leak dampers with low leakage. The main use of these dampers is for places where air leakage or flow control is important. This is the most common discussion in parking lots. In multi-storey car parks where smoke and fire control systems are used For exhaust dampers of each floor, low leakage dampers (double blades) should be used, which in case of fire in the dampers that are closed, the smoke leakage is at the lowest possible level. The bottom is not like double blades and V-blade dampers can be used, but in both of these dampers, the body and blade dampers must be able to withstand fire temperature for 2 hours. As for the engine Permitted dampers for parking lots, according to the new firefighting requirement for these dampers and dampers for fresh air entering the parking lots, permission to use dampers Is not with a return spring mechanism. Therefore, according to this requirement, the motor of smokeless control dampers without return spring can be used, as well as the motors of disconnected dampers. The spring came back and used ordinary disconnection motors for fresh air supply dampers. We suggest using Lufberg-Lufberg damper motor with no spring control model and with status switch with code: FS10N220S The model is 220 volts and for fresh air intake dampers, use the Lufberg-Lufberg dump motor. nDA04N220, DA08N220 Both models are 220V Both of these models can be 24V, but the 220 is more useful. Important for the employer is that the term F300 is mistaken Used for parking dampers. This title is for parking fans in parking lots and, of course, duct accessories, which means enduring the temperature of 300 degrees for 2 hours. Motor dampers mounted on dampers None of any brands can withstand this temperature Motor dampers typically have a temperature tolerance of 50 ° for operating time and 80 ° for maintenance (of course There are some special cases that can withstand temperatures of 117 degrees that do not enter Iran) According to the Tehran Fire Department, so far (summer of 1398) all non-spring-loaded engines for parking lots are approved. But it is better to inquire from this organization before approving and preparing these engines.
