The incoming air

In rural areas, 1 litre of ambient air contains 1 Million particles whereas in urban areas, 1 litre of air contains 1 Billion particles. Many of these particles are pollutants which can range from organic sources (pollen, fungal spores, bacteria, etc.), inorganic sources (due to erosion, sandstorms, fires and salt particles) and also man made sources such as air traffic, industry, mining, agriculture, road traffic, mineral fibres, nanoparticles, smoking, etc.

Damage to health

Many of the particles contained by the air can affect our health. Particles of up to 10 microns are deposited in our noses and throats. Particles of up to 2.5 microns are deposited on our Bronchi and Bronchioli while particles of 1 micron or less are deposited in our alveoli. The damage caused by these particles depends on the amount, size and type of particles present in the air we breathe.

Damage to Machinery

Equipment exposed to dust (airborne as well as deposited on its surface) may underperform and even cause accidents such as Arc flashes. Dust‐free environments are especially required in control rooms, substations and telephone exchanges as the dust particles can cause sensitive electrical equipment to short‐circuit.



The creation and maintenance of positive pressure within a room or vessel through adequate supply of clean (filtered) air will prevent dust from accessing through doors, windows, and leaks. This positive pressure will keep the room and the equipment inside clean whilst ensuring a clean dust-free environment for its occupants.
