Low-Impulse Cone – Intelligent Ventilation for a Better Indoor Climate
A healthy indoor climate is essential for well-being and productivity—especially in industrial environments where heat, humidity, and airborne contaminants can heavily burden the air. At Bardram, we have many years of experience in industrial ventilation, and our specially developed low-impulse cone is an efficient and reliable solution that supports stable and healthy air quality.
The low-impulse cone is designed for use in displacement ventilation systems, where large volumes of cold air are introduced into the room at low velocity. This enables effective and controlled air exchange—without drafts and without unnecessary mixing with the existing air.
Indoor Climate and Ventilation Go Hand in Hand
A good indoor climate is not a luxury—it is a necessity. Poor air quality can lead to headaches, fatigue, reduced concentration, and in the worst cases, illness. That’s why correctly dimensioned ventilation, such as with the low-impulse cone, is an important part of any company’s workplace environment strategy.
Our ventilation solutions ensure:
- Low humidity
- High air exchange
- Reduction of CO₂ levels
- Prevention of mold and bacterial growth
By using the low-impulse cone in displacement ventilation, air is exchanged efficiently and without drafts, creating a stable and comfortable temperature throughout the space—even in large halls.
Improved Indoor Climate Through Targeted Air Distribution
A single cone can handle up to 8,000 m³/h of cold air, making it particularly suitable for spaces with high heat loads or large numbers of people. The air is directed gently and purposefully toward the floor, where it displaces warm and polluted air upward and out. This results in more effective ventilation and a noticeably improved indoor climate with lower CO₂ levels, lower humidity, and reduced risk of headaches, fatigue, and concentration issues among employees.
This method is especially relevant in industries such as manufacturing, logistics, food production, pharmaceuticals, and healthcare, where high demands are placed on air quality and working environments.
Space-Saving and Easy-to-Clean Design
The low-impulse cone is made of stainless steel (AISI 304) and weighs only 39 kg, making it both robust and easy to handle. Its design is compact and optimized for environments with limited space. Both the inner and outer cone can be easily removed, facilitating thorough cleaning and maintenance—an important factor in hygiene-critical settings like food production and laboratories.
Flexible Installation
The unit can be adapted to various installation types and mounted either via wire suspension from the ceiling or wall-mounted using brackets. For optimal effect, the cone should be placed below the boundary layer and not directly above workstations, as this can cause drafts. Its flexible installation makes it easy to integrate the low-impulse cone into both new and existing ventilation systems.
Part of a Holistic Solution
A poor indoor climate can result in reduced efficiency, increased sick leave, and problems with moisture and mold. By investing in a ventilation solution from Bardram, you’re not just buying a technical component—you’re investing in the work environment, productivity, and general well-being of your business. At the same time, energy savings are possible, as we ensure all systems operate with the appropriate air volumes.
We tailor the low-impulse cone to your specific needs in our in-house workshop, and we of course offer consulting, sizing, and installation—whether in a warehouse, cleanroom, or food processing plant. Our condensation-free low-impulse units, another of our products, use displacement ventilation in a similar way and can be connected to the same system for greater effect.

Specially Designed for Demanding Environments
At Bardram, we have over 30 years of experience in delivering customized ventilation solutions for production environments with high standards for hygiene, reliability, and comfort. Our solutions are developed with a focus on functionality and durability—we use materials such as stainless steel or food-grade film where extra resistance to moisture, cleaning, and corrosion is required.
The low-impulse cone is a natural part of these solutions, ensuring efficient and condensation-free air supply—even in cool production environments with high humidity.

Ventilation is a key solution for companies that need to maintain production environments and keep turning profits. Knowledge and insight about your company are important to us when we design solutions.
In rooms with high temperatures, steam, or contamination, process extraction is the way to go. Dust, heat, or contamination can be extracted from the source and create a better environment for your employees.
In all production rooms, machines and other processes will release heat. To maintain a good working environment, it is necessary to cool these rooms down — our products will help with this.
A dry production environment is key to safety. Steam and condensation on your work site can cause big challenges and loss of production time. Our solutions are designed to keep work areas dry so your team can get back to work sooner.

Public guidelines determine how much noise is allowed in your work area, and some production units are too loud. Whether excess sound comes from processes in your production or ventilation units on the roof, we can reduce noise and make both employees and neighbors happy.
The smell of food can be wonderful, but if you are surrounded by it every day it might become too much. With different techniques, we can help you limit the odors created during production inside and outside of the working area.
Save unnecessary expenses by getting your current ventilation system checked. Usually, we can find ways for you to save electricity and money, by reusing the power already generated during production.
We have created our own products, that enables dehumidifying and cooling which will lead to a better working enviroment and increased production time.
