Why Choose Laminar Flow?
Laminar flows are used in all industries where there are high demands on the purity of the air environment. Clean benches for particular environments are equipped with either horizontal or vertical laminar flow. This means that the air flows in one direction and at one speed in parallel lines without backflow. This type of protection and the right enclosure design ensures that the laminar flow protects the work on the clean bench surface. Laminar flow can carry contaminants away from the clean bench to where they can be efficiently collected by filtration and disposed of in another, even more convenient location.
Clean room doors are an essential part of cleanrooms since they are responsible for sealing the controlled environment. If they do not work properly, the cleanroom is exposed to a higher risk of contamination.
Here, Kleanlabs provide 10 key considerations when choosing a cleanroom door based on its many years in the cleanroom construction industry.
1. Completely flat surface
Opt for a door that has a completely flat surface on both sides. If there are no edges for the dust to settle in, it becomes very easy to clean and maintain exceptional hygiene. The best option is a door that has smoothly embedded windows and is completely flush with clean room walls.
2. Easy to integrate
Be aware of system dependence of cleanroom doors. Many manufacturers market doors that can only be integrated into their systems. This makes it difficult to change parameters within the facility without the cleanroom door integrity being compromised. System independent doors however, can be installed into any cleanroom regardless of the manufacturer. Kleanlabs have designed bezels that fit into any wall structure.
3. Thick door panels
Choose a door that is resistant to bending and shock. Kleanlabs recommend a thickness of 60 mm which provides both strength and reliability under most industrial circumstances. Aluminum is a particularly durable material.
4. High level of air tightness
What level of appropriate air tightness should the door have? 3,5 m3/hm2 measured at 200 Pa pressure is a reliable and good value. Some doors can be equipped with double gasket technology and an integrated sink gasket, improving air tightness even more.
5. Resistance to cleaning products
Cleanrooms are exposed to intense cleaning every day with a variety of strong chemicals to assure high levels of hygiene. Cleanroom doors, as any other cleanroom surfaces, need to be resistant to the regular usage of any cleaning products and any reaction between the door and the chemicals need to be avoided. Kleanlabs have carried out several tests to make sure that its own brand of doors resist any cleaning product used within the industry.
6. Safety glazing
In a cleanroom, safety comes first. Therefore, every part of the product should be designed to meet the highest safety requirements. Kleanlab doors are equipped with shatter proof, safety glazing, meaning if the window breaks, it stays in place and there is no risk of scatter.
