Engineering
indoor environments.
Gerhman develops and manufactures ventilation equipment for the people who design and build indoor environments. Our broad portfolio brings together architectural ventilation, airflow control and certified fire and smoke control dampers. With Gerhman Suite, we connect room design and product selection to the technical requirements of each project.
What does Gerhman offer?
A broad product range, connected by engineering expertise. Our solutions support air distribution, indoor comfort, acoustic performance and fire and smoke control.
Ventilation components
Architectural diffusers, grilles and airflow control components that bring ventilation performance into the design of a space.
Air conditioning technology
Heating and cooling solutions, including trench technology and floor convectors, for indoor climate applications.
Noise protection
Sound attenuation solutions for ventilation and air distribution systems.
Certified fire protection and smoke control
Certified fire and smoke control dampers for the safety requirements of building ventilation systems.
Design the room.
Select with purpose.
Move from room conditions to informed product choices. Gerhman Suite brings Room Design, engineering calculations and product selection into one connected workspace.
Start with the room: its dimensions, supply airflow and temperatures. Explore mixing or displacement ventilation, position products and review calculated results against the conditions of your design.
Keep the outcome with your project. With an approved account, you can download a results PDF and save rooms and product selections for your project workflow.
From specification
to site.
Gerhman brings product engineering, manufacturing and application support together to turn technical requirements into practical ventilation solutions. We work alongside engineers, consultants and project teams from the first selection through delivery and beyond.
Engineering & selection
Product selection and technical guidance shaped around the specification, application and architectural intent.
Manufacturing & supply
Manufacturing expertise and coordinated supply to support the requirements of each project.
Application & after-sales
Application guidance, site support and after-sales service that keep our team connected to your project.
Research, Development
& Testing
At Gerhman, research, development and testing connect engineering knowledge with practical product design. Engineering calculations, design evaluations and performance testing help us develop ventilation, air distribution and control solutions for different applications. We use findings from these activities to review product performance, refine design details and support informed technical decisions. From airflow and acoustic behaviour to fire and smoke performance, our approach focuses on the requirements relevant to each product and its intended use.
Quality built into
the way we work.
Our organisation holds certifications covering internationally recognised standards for quality management, environmental management, occupational health and safety, and customer satisfaction. These frameworks support a consistent approach across our operations and customer relationships.
ISO 9001:2015- Quality management
