Knife - for IVAR.PROFI AIR pipe; DN 75 IVAR.RER

Product detailed description

The IVAR.PROFI-AIR ventilation systems are commonly used in residential and commercial buildings to provide efficient air exchange with heat recovery. Installers working on these systems often need to customise duct lengths to suit the layout of the building. The knife is a dedicated tool for this purpose, ensuring clean and precise cuts in the flexible circular ducting of the IVAR.PROFI-AIR CLASSIC series. Accurate cutting is essential to maintain the integrity of the duct and to ensure airtight connections with other system components.

Typical applications include new installations, system expansions, or repairs in HVAC systems where ductwork must be adapted to specific spatial constraints. The knife is used in conjunction with standard tools and materials found in professional HVAC workshops. It is particularly suited for use in tight spaces where larger cutting tools cannot be applied. The tool helps maintain the quality of the ductwork, ensuring that the system operates efficiently and without leaks.

Technical parameters

Nominal diameter	DN 75
Code	IVA010.920.001
Brand	IVAR

The nominal diameter of 75 mm is a key parameter for selecting the correct tool for the duct size. This ensures that the knife is compatible with the specific ducting material and thickness used in the IVAR.PROFI-AIR CLASSIC system. The tool is designed to provide a clean, straight cut without damaging the internal structure of the duct, which is essential for maintaining the performance of the ventilation system.

Installation and connection

To use the knife, the duct should be laid flat on a stable surface. The installer should align the knife with the desired cut line and apply firm, even pressure to cut through the duct material. It is important to ensure that the cut is straight and that no burrs or uneven edges remain, as these can interfere with the connection to other duct segments or fittings. Common mistakes include applying too much pressure, which can deform the duct, or cutting at an angle, which can lead to poor sealing. After cutting, the edges should be checked for smoothness and consistency before connecting to other system components.

Compatibility and accessories

This knife is specifically designed for use with the IVAR.PROFI-AIR CLASSIC ducting. It is not compatible with other duct types or sizes. When preparing for installation, it is important to ensure that all required duct segments and fittings are available. No additional accessories are required for the use of this knife. Installers should also have access to sealing materials and tools for connecting the cut duct segments to the system.

Technical background for designers

The knife is a simple yet essential tool for working with flexible circular ducting in ventilation systems. The duct material is typically made of a flexible yet durable composite that allows for easy bending and shaping during installation. The knife is designed to cut through this material cleanly and efficiently without causing damage to the surrounding structure. The tool is integrated into the installation process to allow for precise adjustments to duct length, ensuring that the system fits the building layout. The quality of the cut affects the long-term performance of the system, as poor cuts can lead to air leaks and reduced efficiency.

Service and operation

The knife requires minimal maintenance. After use, it should be cleaned to remove any debris or residue that may affect its performance. The cutting edge should be inspected regularly for signs of wear or damage. If the edge becomes dull or chipped, the tool should be replaced to ensure continued precision in cutting. There are no specific service intervals provided for this tool; however, regular inspection is recommended to ensure it remains in good working condition.

Frequently asked questions

Can this knife be used with other duct types?
No, this knife is specifically designed for the IVAR.PROFI-AIR CLASSIC ducting and is not suitable for other duct materials or sizes.

Is it possible to cut the duct without using this knife?
While other cutting tools may be used, they may not provide the same level of precision and may damage the duct material.

How should the cut edges be prepared for connection?
The cut edges should be smooth and free from burrs. Any uneven edges should be trimmed or filed before connecting the duct to other system components.

Can this knife be used in tight spaces?
Yes, the compact design of the knife makes it suitable for use in confined areas where larger cutting tools cannot be applied.
