Fibreglass (GRP) Dampers

Industrial Fibreglass Solutions (IFS) manufacture chemical-resistant fibreglass (GRP) dampers for corrosive air and gas handling systems. Our dampers are engineered to provide reliable airflow control and isolation in aggressive industrial and wastewater environments.

By manufacturing locally in New Zealand, IFS is able to offer short lead times, flexible customisation, and lower total project costs compared to imported fibreglass, PVC or metallic damper options.

Product Overview

IFS GRP dampers are available to suit round, square, and rectangular ducting, matching our fibreglass ducting profiles for optimal sealing, alignment, and installation efficiency.

Dampers typically can be supplied in sizes ranging from DN300 to DN1500+ , with configurations tailored to airflow, pressure, and control requirements for each project.

Damper Types Available

  • Sealing / Isolation Dampers
    Provide effective airflow shut-off for maintenance or process isolation.

  • Backdraft Dampers
    Automatically prevent reverse airflow within odour control and ventilation systems.

  • Control Dampers
    Allow accurate airflow modulation and balancing within ducted systems.

Actuation & Control Options

IFS fibreglass dampers can be supplied as manual or actuated units, including:

  • Electric motorised actuators

  • Gearbox-operated dampers

  • Custom actuation arrangements to suit site and control requirements

Actuators can be selected to suit integration with PLC, BMS, or SCADA systems.

GRP Dampers vs Imported Alternatives

IFS GRP Dampers

  • Manufactured locally in NZ

  • Short, predictable lead times

  • Custom sizes and configurations

  • Integrated with GRP ducting systems

  • Lower whole-of-life cost

  • No corrosion

Imported Metallic or GRP Dampers

  • Long international lead times

  • Higher freight and import costs

  • Limited size and configuration flexibility

  • Increased risk of corrosion or coatings failure

  • Delays to projects when changes are required

Typical Applications

  • Wastewater treatment plants

  • Odour control and biofilter systems

  • Industrial exhaust and ventilation systems

  • Chemical and process air handling

  • Corrosive, coastal, and high-humidity environments

Custom Design & System Integration

IFS fibreglass dampers can be custom-designed for each application, allowing easy integration into new or existing ducting systems. Dampers can be supplied as standalone items or as part of a complete GRP ducting package, reducing interfaces, simplifying installation, and improving overall system performance.

Frequently Asked Questions (FAQ)

What sizes of fibreglass dampers do you supply?
IFS manufactures GRP dampers from DN300 to DN1500+, with custom sizes available on request.

Are your dampers suitable for corrosive environments?
Yes. Our GRP dampers are specifically designed for corrosive gases, moisture, and chemical exposure commonly found in wastewater and industrial applications.

Can the dampers be motorised?
Yes. Dampers can be supplied with electric actuators, gearboxes, or manual operation to suit project and control requirements.

How do lead times compare to imported dampers?
Because we manufacture locally, IFS can typically offer significantly shorter lead times than imported damper options, helping reduce project delays and overall costs.
