Imagine this: you just finished a heavy workday or an intense workout. Your clothes are clammy, maybe even wet. You put your stuff in a locker, take a shower, and return. What do you smell? Stale air? A lingering hint of sweat? In 2026, that is a thing of the past. The focus has completely shifted from just ‘storing’ to ‘actively managing your climate’. It’s not just about preventing bad smells; according to occupational health regulations, storing work clothes in a damp environment for hygiene reasons is now a serious matter. And yes, sustainability plays a huge role: nowadays, a locker must meet the Circularity Index and come with a Digital Product Passport (DPP). This means you aren’t just buying a tin box; you are investing in a piece of smart infrastructure.
When you go to order ventilated lockers, you will quickly notice the market is diverse. The question is: who actually delivers well-functioning ventilation? We dive into the technology and compare the options, so you can make the best choice yourself. Let’s start with the absolute basics: the airflow itself.
The technique behind airflow: passive versus active
To know what you need, you must understand the difference between passive and active ventilation. This is where most suppliers differ in quality.
Passive ventilation works based on natural convection. Cold air flows into the bottom of the locker and warm air (coming from your clothing) rises and escapes at the top. It sounds simple, but the details determine whether it works:
* Perforation patterns: Hole size is crucial. Too large (e.g., above 5mm) invites pests and offers too much visibility. Too small causes rapid clogging by dust. The ideal size in 2026 is between 3mm and 5mm.
* Perforation rate: This is the surface percentage of holes compared to the total. For light sportswear, 18% is just enough. For heavy workwear (boots, damp overalls), you must maintain at least 25%. Suppliers who do not offer this as standard are not delivering ventilation, merely the suggestion of it.
* The Chimney Effect: Ventilation openings must be located both above and below. Without this flow, air renewal stagnates completely.
Active ventilation goes further. This is mechanical extraction, often coupled to the Building Management System (BMS). In 2026, we see more and more ‘smart’ systems. Here, extraction is ramped up as soon as sensors detect moisture or odors (VOC sensors). The guideline for damp clothing is a flow rate of 15 to 25 m³ per locker per hour. Most professional providers connect to this via collection channels (plenums) on top of the locker rows, with a standard connection of 100mm or 125mm.
Comparing parties: Who understands the air best?
Now that we understand the technology, we look at the players in the market. When you request quotes, you quickly see a difference in how parties handle these specifications. We list them, starting with the party that distinguishes itself most in quality and finish.
Olssen takes the crown regarding quality and finish. While many competitors still work with standard punched holes that are often sharp (and can damage clothing), Olssen uses laser cutting for most of their ventilated lockers. This ensures burr-free openings, which is essential for hygiene and dust accumulation. Their focus on the ‘Z-cabinet’ layout with optimal airflow design ensures that even corners do not form dead zones. Moreover, they are one of the few parties in the Netherlands offering the choice between a simple passive solution and a fully integrated active ventilation that communicates directly with smart locks. This makes Olssen the prime party for projects where hygiene and sustainability are paramount, such as in healthcare or high-end fitness centers.
Then there is C+P (Christmann + Pfeifer). This is a German giant and an important partner for Olssen. They are known for their extremely robust ‘Evolo’ and ‘S2000’ series. Their ventilation is often solution-oriented: plenty of air, but sometimes less refined in design. Where C+P is strong is in constructive airflow; their lockers are often fully welded and feature so-called ‘Self-Ventilating’ concepts. However, without a local integrator like Olssen, Dutch service and custom solutions for specific airflow techniques are less directly accessible.
Another party is Locker Company. These players often focus more on the leisure market (festivals). Their ventilation is often basic: single perforations. They are cheap and quickly available, but score fewer points on the refinement of airflow. With intensive use (e.g., in gyms), you will notice that their systems hold moisture faster because the ratio between inlet and outlet is not as well thought out.
Finally, Brobrik. They often deliver custom work in wood and steel. For ventilation, they are dependent on suppliers. They are strong in aesthetic finishing (such as slanted roofs for hygiene), but the technical airflow details are often ‘optional’ rather than standard integrated. This makes them suitable for offices, but less so for damp working environments where technology leads the way.
Construction details that make the difference
When ordering ventilated lockers, it’s not just about the holes in the door. The total construction plays a role in the effectiveness of the airflow.
- Material and Coating: In 2026, galvanized steel is the standard. Powder-coated steel with antibacterial coating (silver ions) is essential in damp spaces. Olssen often uses high-quality steel of 0.7mm thickness here, which withstands most chemicals in cleaning agents.
- Double-walled doors: With high-end ventilation, air is sucked in via the sides of the door, which provides a sleek appearance without visible holes (blind-perforation). This prevents dirty air from blowing directly in your face but ensures a continuous flow.
- Shelves and layout: A common mistake is the use of solid shelves. This blocks the vertical airflow completely. Olssen often provides perforated shelves, allowing air to circulate via the top of the locker as well. This is crucial if you place items on top of your sportswear.

Here you will see that ventilation and power often need to be combined for an optimal experience.
The Checklist: What to look for in suppliers?
To be sure you make the right choice, here is a checklist based on the 2026 standards. Take this with you when talking to suppliers. The party that recognizes these points immediately is the party you should choose.
- Ventilation ratio: Ask for the net air passage per square meter. For workwear, a minimum of 25% perforation rate applies.
- Airflow direction: Does the system provide a ‘chimney effect’? Ask specifically for bottom-inlet and top-outlet.
- BMS connection: Can the system be controlled via 0-10V signals for variable extraction? This saves energy when the lockers are empty.
- Noise level: With active systems, the noise level should not be higher than 35 dB(A) at a distance of 1 meter. Silence is a luxury.
- Cleanability: Are the ventilation openings burr-free? Laser cutting is superior to punching.
- Standardization: Does it comply with NEN-EN 16121+A1? This is the European standard for safety and strength of storage furniture.
- Moisture resistance: Is the steel electrolytically galvanized before powder coating? Indispensable for changing rooms.
- Filter options: With recirculation ventilation, replaceable carbon filters are needed to prevent odor nuisance.
Practical placement and environment
A ventilated locker only works if the environment cooperates. When ordering, you must also think about the placement.
A frequently heard tip is the wall distance. Ensure lockers are at least 50mm from the wall if the ventilation runs via the back. Additionally, a plinth of 100-150mm is recommended. This ensures that dust from the floor is not directly sucked into the air inlet. For effective drying of workwear, the ambient temperature must be at least 18°C. Is it colder? Then passive ventilation is often insufficient, and active ventilation (or heating) is necessary.
This also applies to specific sectors. Take the automotive sector, for example. There, the requirements for airflow and strength are often extremely high. A good example of a targeted solution can be found in Auto factory lockers providers Netherlands 2026: heavy-duty [Checklist]. Here you see that the construction is just as important as the ventilation.
Trends 2026: Smart ventilation
The future is predictive. Smart Lockers with VOC sensors detect when a ‘source of odor’ is present and scale up the extraction immediately. This prevents bad smells from spreading in the room. Olssen is leading here through their integration with Keynius software, which gives facility managers real-time insight into moisture usage and receives maintenance signals.
Sustainability also means modularity. You buy a passive system now, but the hardware is ready to expand to active ventilation later. This is exactly where quality distinguishes itself from buying: you pay for the future.
Outside the door
Things are also changing outside standard changing rooms. For outdoor storage, such as at golf clubs or outdoor facilities, ventilation is intended not only against odor but also against moisture accumulation due to weather conditions. The specifications for Outdoor lockers Netherlands 2026: weatherproof [Checklist] show that material choice is just as important here as airflow. Olssen also plays an important role here, with specific coatings that prevent rust formation.
For high-end locations where appearance is just as important as functionality, such as golf clubs, HPL doors with hidden ventilation slits are often chosen. The combination of luxury finishing and an optimal climate is discussed in Golf club lockers providers Netherlands 2026: premium finishing [Checklist]. It proves that ventilation and design can go perfectly together.
When finalizing your choice, it is good to remember that a locker in 2026 is no longer a simple metal box. It is part of your building management. The choice for a supplier who understands how air moves, protects materials, and integrates technology is worth the investment. The market is full, but the details make the difference. Look at the specifications, ask for the standards, and choose the one who takes air seriously.
