In every Textile Industry Humidification or Air Conditioning System requires a proper air filtration device so as to have circulation of clean air in the department.

One of the major menaces in textile industry airflow system is fluff. Fluff / lint suspended in air is a normal feature in almost all textile units, which do not filter return air properly.

Although requisite air flow is a must for textile units to maintain relative humidity the efficiency of air flow system is not, in most of the cases, given due consideration. In most Units the airflow efficiency is NOT EVEN 50% (based on our experience at various units), thereby resulting in wastage of capital investment as well as energy, not to talk of poor end product quality.

When we talk of air circulation we mean supply or fresh air, which mixes with return air coming from department and entering Humidification Plant. This air then flows and diffuses in the department through ducts. The blockade in air passage (i.e. return air duct) caused due to deposition of fluff on filter media is most probably ignored and under the conditions availability of air quantity is drastically reduced. Axial Flow Fans consume same or higher energy for reduced air quantity resulting in huge energy losses.

With due consideration to this problem and inherent draw backs related to Rotary Air Filter and Stationary “V” filter we at PACK PLAST after sufficient R & D exercise have developed AUTO RETURN AIR CLEANSER which over comes the problems related with Rotary Air Filter and “V” Type Stationary Filter.

Our Auto Return Air Cleanser (ARAC) is a properly designed & balanced device to automatically remove fluff at a slow and continuous rate, so that fluff is not converted into small particles, which may mix in the air.

The ARAC is simple in mechanism which offers long trouble free service eliminating the complex fluff problem and minimize the energy wastage due to filter choking partially or fully.

It has been observed that energy consumption increases, to the tune of 30-40% with respect to rated consumption if filter media is unclean.

For example a 50,000 CMH capacity plant, (having 10 HP S/A Fan and 7.5 HP R/A Fan) can waste energy worth Rs. 1,00,000 approx. per annum if it is run with choked R.A. Filter. Also the required conditions in department may not be maintained with set parameters.
