Air is more contaminated than you think We can't always see what can hurt us. Even something as intimate as the air we breathe can be filled with harmful contaminants. Pollution. Allergens. Mould. Viruses. Bacteria. Poor-quality air can be filled with these, all of which can affect our health. And ... Read More

A HEPA filter stops different-sized particles in various ways. Large particles are too big to pass through the gaps in the filter, so they get stuck. Smaller particles (things like bacteria, for example) get stuck to the fibres of the filter, preventing them from passing through. And the smallest ... Read More

Should you go for a traditional cleanroom or a modular cleanroom? Traditional cleanrooms are more of containment rooms. The air inside these cleanrooms is filtered and sent back to the room. However, the modular cleanrooms are pretty different particularly in the context of air flow; they use HEPA ... Read More

The Cleanroom The purpose of every cleanroom is to control an environment by limiting the presence of sub-micron particles and modifying inadequate environmental conditions. The level to which the environment is controlled is what separates one cleanroom from another. For instance, a Class 10 ... Read More

Any air introduced in the controlled zone needs to be filtered. Air filtration involves the separation of "particles" from airstreams. Their removal method is almost as diverse as the size ranges of the particulates generated. Understanding separation techniques requires an exact definition of what ... Read More

1. Each exhaust fan filter box must be opened every six months to check whether the frames of the primary filter, medium efficiency filter and the hepa filter are damaged or aging, and the cabinet should be cleaned and wiped. 2.

Airborne particles Characteristics Airborne particles are solids suspended in the air. For our purposes, particles are defined as bodies with: 1) Definite physical boundaries in all directions. 2) Diameters ranging from 0.001 micron to 100 microns*. 3) Liquid or solid phase material characteristics. ...
