Filtration Systems & Housing

  • Exhaust Mist Separator Units
    Most CNC machines today are enclosed to avoid mist and reduce risk on the shop floor. While exhaust blowers are used additionally to increase visibility, it is essential to separate the mist before letting the air into the working area. The mist composed of water, coolants, or oil needs to be trapped by appropriate media like crimp mesh, foam, felt, etc. To prevent pressure build-up and restriction to airflow, the media must rapidly settle the mist and continuously drain it. Media should be washed periodically for better performance. Pre-filtration of fine solids could be needed to avoid permanent clogging of the media. Filtration down to 25–50 microns is usually adequate, the exception being fine fumes from light oil and fine high-pressure spray, where a 5-micron level is required. An inline cooler can be added for heat loads. In the case of hot air and steam from washing machines, a condenser with a cooling water supply is required to eliminate the steam and remove oil droplets and solid dirt. In the case of totally dry grinding, a cyclonic chamber and a bag filter are required.
  • Filtration Systems
    These customized solutions including automation, pumps, tanks, housings, particle counter, etc. are built around specific process requirements to meet predetermined output. Systems are designed to integrate seamlessly with the existing setup of machinery and processes. What sets us apart from the rest is that the filters required for these systems are designed and manufactured in-house allowing complete flexibility in customization with no dependency on deliverables and an uninterrupted supply of spares at the best prices.
  • Portable Filtration Units
    Liquids - There are six models that can be used for oils, coolants, glycols, etc. with suitable elements. These heavy-duty, rugged units are capable of full flow-through filtration across a wide micron range and dirt levels. Though filtration is possible in a single pass, recirculation ensures complete cleaning. Vigorous circulation also removes all dirt accumulated at the tank bottom (not done by ELC). Regular use of these units keeps various machine oils sparkling clean, avoids disposal, and also reduces the consumption of the original small imported filters. These can then be made of washable stainless steel mesh in sizes of 25 or 50 microns. This is the lowest-cost, safest option without maintenance problems. A typical use of 4–8 hours once a month can serve 25–50 machines. This is the ideal choice for the shop floor of the engineering industry. A comparison is given with other types. Target dirt level (w/o ELC) < 10 mg/lit, NAS < 7. (ELC can be used for further reduction if required.) Using a centrifugal pump and epoxy-coated housing, the unit can be used for aq, coolant, and other liquids.
  • Standalone Filtration Units
    These custom-designed filtration units include the filter element as well as the outer casing called housing. They are supplied in various sizes and designs based on the application and operating parameters. They are more like add-ons to the existing system for improving performance and reducing costs.
