Ck airtech india private limited. Manufacture and supply the cyclones and multi cyclones. It is highly energy efficient and less noisy. These are widely used for collection of coarse dust particles. Their cyclones are successfully designed to remove dust with an emission level of 200 mg/m 3 . The pressure drop across the cyclones are as low as 50-100 mm wg resulting in energy savings. For high dust loading condition they act as primary filtering system before the bag filter. They do not need any preservation. Multicyclones are offered to handle larger volumes of hot gas. These are also offer to achieve better operating efficiencies. Rotary air cut valves or double flap valves are used as discharge devices to these cyclones.
