High-strength structure

Damper frames and blades are made from high-quality galvanized or stainless steel plates, with brass bearings and robust corner-joint assembly.

Low leakage performance

Damper sealing can use elastic stainless-steel side seals and silicone seals between blades, providing excellent overall sealing performance that meets standards such as JG/T436-2014.

Multiple actuator options

The damper can use manual sector, manual screw, electric spring-return, electric two-position, electric modulating, or pneumatic actuators.

Before Installation

  • Check that product specifications match design requirements
  • Confirm installation location and space
  • Prepare installation tools and accessories
  • Check duct connection dimensions

Installation Steps

  1. Reserve installation space in the duct system
  2. Install the damper in the specified position
  3. Connect ducts and ensure good sealing
  4. Install actuator and control wiring
  5. Perform system commissioning and calibration
  6. Check operating status and control accuracy

Notes

  • Pay attention to airflow direction during installation
  • Ensure the actuator is securely installed
  • Regularly check sealing performance
  • Avoid overpressure operation
