Shelter Ventilation

DUCT TYPE SHELTER POWER PLANT (DUCT TYPE SHELTER POWER PLANT)
Channel type shelter stations are designed to be mounted on the ceiling. The body of the power plant is manufactured from 1 mm thick galvanized sheet. The blowing fan is manufactured from galvanized sheet metal by using an external rotor motor. In addition, the fan is statically and dynamically balanced. There is a G4 or F7 cassette filter as a pre-filter, an active carbon filter and a radioactive hepa filter for use in dangerous times. Optionally, a lead separator can be added, and the inner walls can be covered with a lead plate.
System operation; It starts with the activation of the fan, normally the filter damper is in the closed position and the bypass damper is open, so the fresh air sucked from outside passes through the cassette filter and is pressed inside. In dangerous times, the bypass damper is closed and the filter damper is open. The sucked fresh air passes through the cassette filter, active carbon filter and hepa filter and is pressed in. The air damper to be adjusted is made by a single arm. When the arm is turned, the bypass damper opens and the danger damper closes. When the arm is reversed, the opposite of this process is done.

DOUBLE FUNCTION SHELTER PLANT
Power plant casing is manufactured from aluminum profiles, while the body is covered with 0.8 mm galvanized sheet inside and 0.8 mm painted sheet outside. Body panels are filled with 25 mm thick polyurethane.
The blowing fan is double suction, high pressure and belt-pulley type. Electric motor can be used as single-phase or three-phase optionally.
In the plant, there is a G4 or F7 cassette filter as a pre-filter, an active carbon filter and a radioactive hepa filter for use in dangerous times. Optionally, a lead separator can be added, and the inner walls can be covered with a lead plate.
System operation; It starts with the activation of the fan, in normal time the filter damper is in the closed position and the normal time damper is in the open position, so the fresh air sucked from outside passes through the cassette filter and is pressed inside. If it is in danger time, the normal time damper should be closed and the filter damper open. The sucked fresh air passes through active carbon filter, hepa filter and cassette filter and is pressed in.
The air damper to be adjusted is made by means of two arms. In the time of danger, the hazard damper arm is switched to the open position, the normal time damper is kept in the closed position. In normal time, the normal time damper should be kept in open position and the danger damper in closed position.
