A properly sized suction system not only keeps the clinic free of dust and bioaerosols; it also protects the practitioner’s airway, reduces cross-contamination, and prolongs the life of the micromotors. Below are the technical parameters, installation best practices, and preventive maintenance based on field experience with Namrol vacuum cleaners (e.g. Aerobox<\/a>, Air\u2011S and units integrated into Duna<\/a> y Futura Plus<\/a>).<\/p><\/div><\/div><\/article><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Namrol brushless motors eliminate mechanical friction and carbon dust, two common sources of premature failure. Benefits:<\/p>

  • Stable torque<\/strong>: Current is electronically regulated, maintaining constant flow even when the filter is at 60% load.<\/p><\/li>

  • Lower operating temperature<\/strong>: +\u202f20\u201325\u202f\u00b0C lower than brushed motors, which reduces dust wetting in the bag.<\/p><\/li>

  • Continuous duty cycle<\/strong>: Suitable for workdays of more than 8 hours without mandatory breaks.<\/p><\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    1. High-capacity prefilter (bag)<\/strong><\/p>

      • Material: Electrostatically charged microfiber.<\/p><\/li>

      • Replacement: When the pressure drop reaches 40% of the initial value (approximately every 120 hours of standard clinical use)<\/p><\/li><\/ul><\/li>

      • HEPA\u00a0H13<\/strong><\/p>

        • Retention \u2265\u202f99,95\u202f% at 0,3 \u00b5m.<\/p><\/li>

            • Bend radius<\/strong> \u2265\u202f3 \u00d7 D \u2192 each sharp bend (+\u202f90\u00b0) can subtract up to 50 mm H\u2082O.<\/p><\/li>

            • Total lenght<\/strong> <\u202f2,5\u202fm; if exceeded, upgrade to \u00d8 32 mm or install a booster.<\/p><\/li>

            • Sealing joints<\/strong>: clamps with NBR gasket; a 4\u202f% leak can reduce the effective flow rate by 15\u202f%.<\/p><\/li>

            • Location<\/strong>: Place the vacuum cleaner under the work table with anti-vibration foam; this prevents conduction of structure-borne noise and shortens the suction distance.<\/p><\/li><\/ul>

              Ergonomic tip<\/strong>: combines an on\/off pedal and a handle with a fine-tuning valve to adjust the suction without stopping the micromotor.<\/p><\/blockquote><\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
