LAMINAR AIR FLOW BENCH is classified based on the air flow pattern. If the Airflow pattern is horizontally across the work table is called horizontal laminar air flow and if the air flow is vertically downwards on the work table surface is called vertical laminar air flow. In both types principally the room air is taken through a pre filter which arrest larger size particle by which the life of HEPA filter increases. The pre filtered air is forced through HEPA filter, results a stream of unidirectional clean air flow within the work table surface of the work bench. A nominal filter face velocity of 80 to 100 fpm ensures sufficient number of air changes in order to maintain desired cleanliness level. The filtered air moves out from the front open space of cabinet. The LAF unit is constructed out of GI powder coated sheets & MS powder coated sections in combination with SS work table surface or alternatively all SS construction.

Cyclonic separation is a method of removing particulates from an air stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate particle from the dust laden air. Cyclone Separators Cyclone body will be cylindrical in the top portion and conical shape at the bottom as shown in the drawing. The air stream will enter into the cyclone body tangentially in the top cylindrical with high velocity. The top portion of the cyclone body guides the air to move in circular pat in high velocity. A cyclonic effect (twister) will be created inside the body and the air stream move downwards in the heavier dust particles in helical pattern. The heavier particles in the air stream have too much inertia, while moving in cyclonic effect and move towards outer peripheral of the cyclonic effect in the air stream. When the particles are striking the inner surface of the cyclonic body, it will lose its momentum and fall down. In a conical system, as the rotating flow moves towards the narrow end of the cyclone, the rotational radius of the stream is reduced, thus separating smaller and smaller particles. Cyclone is called as pre collector in the dust extraction system. Cyclone has good efficiency in dust separation for large size particles and fiber dust particles. Cyclone separator will be used to segregation of items or products in the conveying systems. Cyclone separator MOC will be defined by the application and nature of dust to be handled.

Dust Proofing System is requirement of certain process / activities such as assembly of precision components, packing of precision products, painting process, electronic components assembly.
Dust proofing environment requirement arises
To meet dust proofing system, the process area is provided with filtered fresh air systems. The classification of filtration depending on the process/ equipment. To obtain dust proof zone the area need to be air tight to arrest leakage of supply air to establish positive pressure inside the area with respect to outside area or adjacent areas. The positive pressure inside will prevent dust / hazardous entry from outside.
This helps the process in a dust free environment. We can add cooling system also in the air handling unit of the pressurization system based on the requirement of process. Air lock rooms for material entry & men entry are must for dust proof systems. The in dust generation & heat generated by process can be tackled by suitable extraction system & can not only be controlled by dust proof systems.
Evaporative cooling systems have added advantage in achieving higher comfort level in manufacturing & general engineering industries. Ventilation supply air systems draws the outside air & filter it to the required micron level & distribute air to occupied areas to meet comfort. In evaporative cooling system, the same fresh air system is equipped with a water circulated cooling pad & the filtered dry air at ambient temperature is allowed to pass through cooling pad, their by the dry bulb temperature of air it will brought down and cooled air will be distributed to the occupied areas. Which make more comfort if the occupied area. This is an adiabatic cooling process where large occupied areas to be brought under comfort level. Evaporative cooling system is working with the principle that when the air is passing through water circulated cooling pad, water will be evaporated by taking the energy (heat) from the fresh dry air in an adiabatic process, due to the difference between dry bulb temperature and wet bulb temperature. Energy loses due to change water from liquid to vapour results in reduction of dry bulb temperature of air. These systems are more suitable and efficient where ambient temperature is too high & low RH levels. In case if it use a chilled water spray in the cooling pad in place of normal water the room temperature will be still better & close to air conditioning comfort. This application has a main disadvantage is the relative humidity level will be high (over 70%) which place an important role & can affect the manufacturing process & products where the humidity levels are the criteria. Evaporative cooling system comprises of following Air inlet section Filters Water circulated cooling pad Re circulation water pump with internal water sump Blowers / Air Handing units Ducts Register/grills for distributing the air within the work space

An impingement-plate scrubber is a vertical chamber with plates mounted horizontally inside a hollow shell. Impingement-plate scrubbers operate as countercurrent particulate matter (PM) collection devices. The scrubbing liquid flows down the tower while the gas stream flows upward. Contact between the liquid and the particle-laden gas occur on the plates. The plates are equipped with openings that allow the gas to pass through. Some plates are perforated or slotted. The simplest impingement-plate scrubber is the sieve plate, which has round perforations. In this type of scrubber, the scrubbing liquid flows over the plates and the gas flows up through the holes. The gas velocity prevents the liquid from flowing down through the perforations. Gas-liquid-particle contact is achieved within the froth generated by the gas passing through the liquid layer. Complex plates, such as baffle plates, introduce an additional means of collecting PM. The baffles placed above the plate perforations force the gas to turn before escaping the layer of liquid. While the gas turns to avoid the obstacles, most PM cannot and is collected by impaction on the baffles.
High precession clean room activity recommends an AIR SHOWER for people entering into clean room. This is to prevent dust, contaminates carried through apparel worn by operators. Air shower is self contained equipment designed to provide high velocity HEPA filtered air through air jets nozzles located inside shower area. Air shower is provided with two electrically interlocked doors for entry & other for exit.

Fabric filter bags are used to separate particle from the dust laden air in bag filter unit. They are one of the most efficient and cost effective types of dust collectors available and can achieve a collection efficiency of more than 99% for very fine particulates. Mechanical shaking Dust-laden gases enter the bag filter unit and pass through fabric bags that act as filters. The bags can be of woven or felted cotton, synthetic, or glass-fiber material in either a tube or envelope shape. The high efficiency of these collectors is due to the dust cake formed on the surfaces of the bags. The fabric primarily provides a surface on which dust particulates collect through the following four mechanisms: Inertial collection - Dust particles strike the fibers placed perpendicular to the gas-flow direction instead of changing direction with the gas stream. Interception - Particles that do not cross the fluid streamlines come in contact with fibers because of the fiber size. Brownian movement Sub micrometre particles are diffused, increasing the probability of contact between the particles and collecting surfaces. Electrostatic forces - The presence of an electrostatic charge on the particles and the filter can increase dust capture.
Recovery of particulate matter from exhaust gas is vital for any industry from three aspect To ensure the operators health and safety by removing the hazardous fumes from the working area To avoid pollution problems Sturdy construction To increase the product quality removing fumes from the process Dust collection systems is used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere. Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air quality. The dust generation in manufacturing process directly effects the operators health, can contaminate the product which is being manufacturing can make highly uncomfortable for the people in & around the dust generating areas. BATS wish to offer a solution by incorporating dust control & extraction system & ensure a safe & pure zone for the occupants. This process involves exhaust blowers, exhaust air duct work and dust collection hoods to pick up dust particles at the point of generation. In several cases, the dust collected by the system from the point of generation is routed through a filter unit which collects the dust & pure air will be exhausted to the ambient to meet pollution control.
This is a process requirement design where humidity levels requirement is more than 60 to 70% simultaneously enhances the comfort level due to adiabatic cooling process. Indoor air quality solutions mushroomed in the industries as the process demands controlled humidity level and people become more aware of health related issues. The ashrae standard range for optimum indoor relative humidity is between 40-60% year round. Controlling indoor relative humidity is important to health because too little humidity can create microscopic cracks in a persons nasal membrane, leaving the body more vulnerable to infections from bacteria and viruses. Conversely, too much humidity creates ideal breeding conditions for mold, mildew and dust mites; from which the waste products are among the most troublesome triggers of asthma and allergies. The outside air is filtered & allows passing through a water spray zone in the air handling unit. The air leaving the water spray zone will have more moisture & this air will be distributed to the manufacturing process area to meet their process requirement. The following industries generally needs humidification plant tobacco process textile process painting wood working hospital pharmaceutical food processing printing steel rolling mill
