Системы распределения воздуха в чистых помещениях
Снижающий давление амортизатор в чистой комнате
A finely balanced wall or duct damper that opens above an adjustable pressure differential and closes as the cleanroom returns to its intended cascade.
- Adjustable Differential Setpoint
- Balanced Aerofoil Relief Blade
- Wall or Duct Installation
- Gravity Return Closure
Введение продукции
The cleanroom pressure relief damper uses a low-friction pivoted aerofoil blade and adjustable balance weights to bleed excess air from a positive room. When the differential rises above the selected opening value, blade torque overcomes the balance and the damper opens progressively. As room pressure falls, gravity and the counterweight return the blade toward the sealed position. A wall sleeve, protective grille and accessible weight rail allow the unit to be integrated into clean partitions without exposing the moving mechanism to routine traffic.
Основные характеристики
Movable weights allow the opening threshold to be adjusted for the intended cleanroom cascade.
Progressive blade travel relieves increasing airflow while avoiding the abrupt full-open action of a simple flap.
Wall, partition and duct configurations accept protective grilles and cleanable powder-coated finishes.
Обеспокоенность клиентов продуктами
Room-pressure relief must respond at only a few pascals, avoid chatter and close against reverse contamination flow when the positive differential disappears.
Door opening effort rises because the room has no controlled path for excess supply air.The balanced blade opens at the selected differential and releases only the airflow needed to limit overpressure.
A crude gravity flap oscillates as the room controller trims the supply airflow.Aerofoil blade geometry and distributed counterweights provide smoother progressive travel around the setpoint.
Reverse airflow enters when an adjacent room briefly becomes more positive.Gravity return and blade seals close the transfer path as soon as the intended pressure direction is lost.
The counterweight setting is inaccessible after the damper is installed in the wall.A removable clean-side grille exposes the calibrated weight rail without dismantling the sleeve.
