![]() ![]() Observe the correct shielding and possible extraction of released dry and liquid substances. Air turbulence can cause deposits on unwanted places. Liquid material is removed, forming a spray. All health and safety aspects must be observed. Using air knives, particular attention should be taken to control dust and liquid being removed. Benefits of circular air knife: uniform airflow 360 º, divisible, infinitely adjustable outlet velocity of flow, no physical contact with the material passed through, 'split design', compact design The air consumption compared with traditional methods (tube with holes) is. The right choice is partly determined by the desired internal diameter and operating conditions (whether aggressive environment and / or company rules). The combined airflow forms a closed ring of 360 º and cleans the exposed object / product.ĪirWipes are available in various diameters (13-279 mm free passage). Negative pressure is created through which ambient air adds to the primary airflow. This primary airflow moves along the Coanda-surface in the direction of the object to be cleaned. Through a narrow gap, the expanding air is blown at an angle of 30 º. The circular air knife - Fiktech AirWipe - is a simple solution to many clean elongated products from and moisture with compressed air Compressed air of up to 7 bar (R) is supplied to the inlet and is evenly distributed in the circular plenum. Open bags for automatic filling systems etc.Cooling and / or drying of components with various dimensions.Separation of multiple process conditions / environments.Push Pull systems for the removal of dust, fumes, vapor.Blowing off fluids of miscellaneous objects.Easy to mount, no moving parts, almost wear-free.Standard lengths and specials available.Aluminium and Stainless Steel 304/316 versions.Evenly ditributed airflow, high speeds (up to 200 m / sec.) & blow-off force. ![]() ![]() Effective Way to blow off moist & particles, drying, cooling and cleaning.The cost of energy determines 64% of the total cost of the compressed air!Ĭompare the energy consumption of the HP and LP air knivesįeatures and benefits of air knives & air guns In general, one must consider that - a Nm3 air costs 2.4 cents - at an energy of 14 cents per kWh. In these cases it's better to opt for LP Air knives or air guns, which generate significantly higher air speeds and are energetically favorable. HP Air Knives are more compact constructed compared to the LP versions, but the compressed air consumption is rapidly increasing at greater lengths. HP (High Pressure) Air knives use compressed air, LP (Low Pressure) Air knives are powered by a side channel blower. The connecting pipe work should be dimensioned in the right way in order to minimize pressure losses.Īir knives and air guns are available in both aluminium and stainless steel. However, the air supply must be clean, by the use of appropriate filters. Observe the correct shielding and possibly of extraction of dry and liquid substances released.īecause air knives contain no moving parts, they ask little maintenance. Due too air turbulence spray may be deposited on unwanted places. Liquid material which is removed, may form a spray. All health and safety aspects should be observed carefully. One must pay particular attention to the control of dust and liquid which will be removed by the air knife. ![]()
