Product information

Description

The VENTS GRM450X450 is a high-quality external gravity shutter specifically engineered for ventilation systems requiring reliable backdraft protection. Designed for wall-mounted installation, this shutter measures 450 x 450 mm and serves as an essential component for both domestic and industrial ventilation setups. It functions automatically by utilizing the airflow generated by the fan to open the louvers during operation and closing them securely via gravity once the fan is switched off.

Advantages

This gravity shutter offers a robust and maintenance-free solution for managing airflow in various environments. Its primary advantage lies in its automatic operation, which requires no electrical connection or manual intervention, ensuring seamless integration with existing fan systems. The durable construction provides excellent resistance against outdoor weather conditions, effectively preventing backdrafts, debris, and insects from entering the building through the ventilation duct when the fan is inactive.

Suitable for

  • Industrial ventilation systems
  • Domestic wall-mounted exhaust fans
  • Commercial kitchen or workshop ventilation
  • Buildings requiring protection against outdoor elements

When it may not be suitable

This shutter is not designed for use in high-pressure ventilation systems where the fan power is insufficient to lift the gravity-operated louvers. It is also not intended for installation in ducts that require airtight sealing, as gravity shutters are designed for airflow regulation rather than hermetic closure.

Key specifications

  • Dimensions: 450 x 450 mm
  • Operation: Automatic gravity-based
  • Mounting: Wall-mounted
  • Function: Backdraft prevention
  • Compatibility: Suitable for industrial and domestic fans

How to use

The shutter should be installed on the exterior wall directly over the ventilation fan outlet. Ensure the frame is mounted level and securely fastened to the wall surface to allow the louvers to move freely without obstruction. Once installed, the shutter will automatically respond to the air pressure created by the fan, opening when the fan is active and closing immediately when the airflow ceases.

What to consider before purchase

  • Verify the dimensions of your existing fan outlet to ensure a proper fit
  • Ensure the wall surface is flat for secure mounting
  • Check that the fan has sufficient power to open the shutter blades

Usage recommendations

Regularly inspect the shutter to ensure that the louvers remain free of dust, grease, or debris, which could impede their movement and affect the efficiency of your ventilation system.
